This commit significantly improves the project's documentation. The `frontend/README.md` has been completely rewritten from the boilerplate template into a comprehensive guide. It now includes detailed sections on features, tech stack, and project structure. The root `README.md` is updated to reflect the latest application features, including smart notifications, sound alerts, and interactive charts.
This commit introduces a new script, `scripts/deploy-prod.js`, to automate the deployment of the application to a production environment. This will streamline the release process and reduce manual errors. In addition, this commit includes the following changes: - Renames the project in `package.json` from "Technical_Assignment" to "financial-dashboard" for better clarity. - Updates various npm dependencies to their latest versions.
This commit streamlines the deployment process by introducing npm scripts and automating frontend configuration. Key changes: - Replaced manual `npx hardhat run` commands with simpler `npm run deploy:local` and `npm run deploy:holesky` scripts. - Automated the process of updating frontend environment variables (`.env.local`) with contract addresses upon deployment, removing a manual step. - Updated the root and frontend README files to reflect the new, simplified workflow. - Added detailed instructions for deploying to the Holesky testnet and for deploying the frontend to Vercel.

This commit introduces role-based data fetching and display for the dashboard, providing tailored views for Admins, Managers, and regular Users. - **Role-Specific Metrics:** The dashboard now fetches and displays different metrics based on the user's role (Admin, Manager, User). Admins see platform-wide statistics, while other users see data relevant to their scope. - **Detailed Chart Breakdown:** The dashboard chart is updated to show a more granular breakdown of transaction statuses, including pending, active, completed, and rejected. - **Admin Transaction View:** The "Recent Activity" panel now shows all platform transactions for admins, instead of just their own. - **Backend Integration:** The API service and hooks (`useDashboardMetrics`, `useTransactions`) have been updated to pass the user's role to the backend, enabling role-specific data retrieval. - **Type Safety:** The `DashboardMetrics` type and `UserRole` enum have been expanded to support the new metrics and roles.
- Add unique toast IDs to prevent duplicate notifications - Remove redundant transaction completion toast (handled by WalletProvider)

🧹 Nitpick comments (47)
frontend/next.config.ts (1)
1-7: Consider adding security configurations for financial platformThe basic Next.js configuration structure is correct. However, for a financial platform, consider adding security headers, CSP policies, and other production-ready configurations.
const nextConfig: NextConfig = { - /* config options here */ + experimental: { + serverComponentsExternalPackages: ['web3', 'ethers'] + }, + async headers() { + return [ + { + source: '/(.*)', + headers: [ + { + key: 'X-Frame-Options', + value: 'DENY' + }, + { + key: 'X-Content-Type-Options', + value: 'nosniff' + } + ] + } + ]; + } };contracts/FinancialPlatform.sol (2)
90-90: Consider gas implications of unbounded array growthThe
allApprovalIdsarray will grow indefinitely as approvals are created. For high-volume platforms, this could lead to gas issues when iterating or accessing the array.Consider implementing a pagination mechanism or cleanup strategy for old approvals to manage gas costs in production.
366-368: Consider pagination for scalabilityThe
getAllApprovalsfunction could become expensive with many approvals. Consider implementing pagination to handle large datasets efficiently.-function getAllApprovals() external view onlyApprover returns (uint256[] memory) { - return allApprovalIds; -} +function getAllApprovals(uint256 offset, uint256 limit) external view onlyApprover returns (uint256[] memory, uint256 total) { + uint256 totalApprovals = allApprovalIds.length; + if (offset >= totalApprovals) { + return (new uint256[](0), totalApprovals); + } + + uint256 end = offset + limit; + if (end > totalApprovals) { + end = totalApprovals; + } + + uint256[] memory result = new uint256[](end - offset); + for (uint256 i = offset; i < end; i++) { + result[i - offset] = allApprovalIds[i]; + } + + return (result, totalApprovals); +}frontend/src/lib/utils.ts (1)
4-5: Prefer spreading the rest-parameter for clearer intent
clsxaccepts a variable-length argument list. Passing the wholeinputsarray works becauseclsxflattens arrays, but writingclsx(...inputs)avoids the extra array wrapper and makes the intent unambiguous.- return twMerge(clsx(inputs)) + return twMerge(clsx(...inputs))package.json (1)
2-3: Add"private": trueto prevent accidental publishBecause this repository is a monorepo with Solidity contracts and a Next.js frontend, publishing the root package to npm is unlikely to be desirable. Adding the flag is a one-liner:
"name": "financial-dashboard", + "private": true, "type": "commonjs",frontend/eslint.config.mjs (1)
12-14: Consider sharing rules with the backend to avoid divergent lint behaviourOnly the Next-specific presets are extended here. If the repo contains non-Next Node code (e.g. Hardhat scripts), you may want to include
eslint:recommendedor a shared base to keep consistent rules across folders.No action required if intentional.
frontend/src/components/ui/label.tsx (1)
15-17:VariantPropsinclusion is unused – remove until variants are added
VariantProps<typeof labelVariants>is currently never referenced inside the component. Dropping it reduces noise and speeds up type-checking; you can re-introduce it once actual variants are declared.- React.ComponentPropsWithoutRef<typeof LabelPrimitive.Root> & - VariantProps<typeof labelVariants> + React.ComponentPropsWithoutRef<typeof LabelPrimitive.Root>frontend/src/components/ui/sonner.tsx (1)
11-11: Improve type safety for theme prop.The type assertion
theme as ToasterProps["theme"]could be more type-safe. Consider validating the theme value or using a more explicit type guard.- theme={theme as ToasterProps["theme"]} + theme={theme === "light" || theme === "dark" || theme === "system" ? theme : "system"}frontend/src/components/ui/page-size-selector.tsx (1)
19-19: Consider using clsx or cn utility for className concatenation.The template literal className concatenation could be more maintainable with a utility function.
- <div className={`flex items-center gap-2 text-sm ${className}`}> + <div className={cn("flex items-center gap-2 text-sm", className)}>You'll need to import a className utility like
cnfrom your utils.frontend/src/components/debug/EventListenerStatus.tsx (1)
36-38: Consider responsive text wrapping.The responsive classes
w-full sm:w-autohelp with mobile layouts, but consider if the text should be more responsive or if line breaks might be awkward on some screen sizes.- <span className="text-xs text-gray-500 w-full sm:w-auto"> + <span className="text-xs text-gray-500 max-w-full break-words"> You will receive real-time notifications for blockchain events </span>frontend/tsconfig.json (2)
3-3: Consider updating TypeScript target for modern browsers.ES2017 is quite conservative for modern web applications. Consider using ES2020 or ES2022 for better performance and modern language features.
- "target": "ES2017", + "target": "ES2020",
7-7: Consider enabling additional strict options.For better type safety, consider enabling additional strict TypeScript options.
"strict": true, + "noUncheckedIndexedAccess": true, + "exactOptionalPropertyTypes": true,frontend/src/lib/providers.tsx (1)
14-18: Consider the performance impact of aggressive refetching.The 30-second stale time combined with 30-second refetch intervals and background refetching may be quite aggressive for performance, especially with multiple components mounting. This could lead to excessive network requests and battery drain on mobile devices.
Consider increasing the stale time to 60-120 seconds or making the refetch interval configurable based on the component's importance.
frontend/src/components/transactions/CreateTransactionForm.tsx (1)
91-103: Consider the amount input configuration.The amount input uses
type="text"with astepattribute, which is unusual sincestepis typically for number inputs. For ETH amounts requiring high precision, using text input is actually correct to avoid floating-point precision issues, but thestepattribute has no effect on text inputs.Consider removing the
stepattribute since it's not functional withtype="text".- type="text" - placeholder="0.1" - step="0.000000000000000001" + type="text" + placeholder="0.1"scripts/update-frontend-config.js (1)
30-38: Consider more robust environment variable updates.The regex replacement approach works for the happy path but could be fragile if the environment variables don't exist in the file or have unexpected formatting. Consider a more robust approach that can handle missing variables.
- // Update contract addresses - envContent = envContent.replace( - /NEXT_PUBLIC_FINANCIAL_PLATFORM_ADDRESS=.*/, - `NEXT_PUBLIC_FINANCIAL_PLATFORM_ADDRESS=${deploymentInfo.contracts.FinancialPlatform}` - ); - - envContent = envContent.replace( - /NEXT_PUBLIC_MOCK_TOKEN_ADDRESS=.*/, - `NEXT_PUBLIC_MOCK_TOKEN_ADDRESS=${deploymentInfo.contracts.MockToken}` - ); + // Update or add contract addresses + const updateOrAddEnvVar = (content, key, value) => { + const regex = new RegExp(`^${key}=.*`, 'm'); + if (regex.test(content)) { + return content.replace(regex, `${key}=${value}`); + } else { + return content + `\n${key}=${value}`; + } + }; + + envContent = updateOrAddEnvVar(envContent, 'NEXT_PUBLIC_FINANCIAL_PLATFORM_ADDRESS', deploymentInfo.contracts.FinancialPlatform); + envContent = updateOrAddEnvVar(envContent, 'NEXT_PUBLIC_MOCK_TOKEN_ADDRESS', deploymentInfo.contracts.MockToken);frontend/src/components/layout/AppLayout.tsx (1)
77-81: Consider extracting complex className logic for better readability.The sidebar className logic is complex and could benefit from extraction for maintainability.
+const sidebarClasses = ` + ${sidebarOpen ? "translate-x-0" : "-translate-x-full"} + fixed inset-y-0 left-0 z-40 w-64 bg-white shadow-lg + transform transition-transform duration-300 ease-in-out + lg:translate-x-0 lg:static lg:inset-0 h-screen lg:h-screen +`; <div - className={`${ - sidebarOpen ? "translate-x-0" : "-translate-x-full" - } fixed inset-y-0 left-0 z-40 w-64 bg-white shadow-lg transform transition-transform duration-300 ease-in-out lg:translate-x-0 lg:static lg:inset-0 h-screen lg:h-screen`} + className={sidebarClasses} >frontend/src/components/users/UserManagement.tsx (1)
18-32: Enhance accessibility of the access restriction message.The access restriction UI could be more accessible and informative.
<Card> <CardContent className="flex items-center justify-center py-8"> <div className="text-center"> <AlertCircle className="h-12 w-12 text-gray-400 mx-auto mb-2" + aria-hidden="true" /> - <p className="text-gray-600">Access restricted to administrators</p> + <h2 className="text-lg font-semibold text-gray-600 mb-2"> + Access Restricted + </h2> + <p className="text-gray-600">This area is limited to administrators only</p> <p className="text-sm text-gray-500 mt-1"> Only users with Administrator role can manage platform users </p> </div> </CardContent> </Card>frontend/src/components/ui/textarea.tsx (1)
11-14: Consider adding resize control option.The textarea could benefit from resize control options for better UX in different contexts.
export type TextareaProps = React.TextareaHTMLAttributes<HTMLTextAreaElement> & { + resize?: 'none' | 'both' | 'horizontal' | 'vertical' } const Textarea = React.forwardRef<HTMLTextAreaElement, TextareaProps>( - ({ className, ...props }, ref) => { + ({ className, resize = 'vertical', ...props }, ref) => { return ( <textarea className={cn( - "flex min-h-[80px] w-full rounded-md border border-input bg-background px-3 py-2 text-sm ring-offset-background placeholder:text-muted-foreground focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:cursor-not-allowed disabled:opacity-50", + "flex min-h-[80px] w-full rounded-md border border-input bg-background px-3 py-2 text-sm ring-offset-background placeholder:text-muted-foreground focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:cursor-not-allowed disabled:opacity-50", + resize === 'none' && 'resize-none', + resize === 'both' && 'resize', + resize === 'horizontal' && 'resize-x', + resize === 'vertical' && 'resize-y', className )} ref={ref} {...props} /> ) } )frontend/src/app/approvals/page.tsx (1)
18-24: Enhance loading state with proper loading indicator.The current loading state is too basic for a production application.
Consider using a proper loading spinner:
if (isInitializing) { return ( <div className="min-h-screen bg-gray-50 flex items-center justify-center p-4"> - <p>Loading...</p> + <div className="flex flex-col items-center gap-4"> + <Loader2 className="h-8 w-8 animate-spin text-blue-600" /> + <p className="text-gray-600">Loading approvals...</p> + </div> </div> ); }You'll need to import
Loader2fromlucide-react.frontend/src/app/users/page.tsx (1)
14-20: Maintain consistent loading states across pages.This loading state has the same basic implementation as the approvals page. Consider creating a shared loading component for consistency.
Create a shared
LoadingScreencomponent:// components/ui/LoadingScreen.tsx import { Loader2 } from 'lucide-react'; interface LoadingScreenProps { message?: string; } export function LoadingScreen({ message = 'Loading...' }: LoadingScreenProps) { return ( <div className="min-h-screen bg-gray-50 flex items-center justify-center p-4"> <div className="flex flex-col items-center gap-4"> <Loader2 className="h-8 w-8 animate-spin text-blue-600" /> <p className="text-gray-600">{message}</p> </div> </div> ); }Then use it in both pages:
- <div className="min-h-screen bg-gray-50 flex items-center justify-center p-4"> - <p>Loading...</p> - </div> + <LoadingScreen message="Loading users..." />scripts/deploy-prod.js (2)
56-62: Improve error handling for frontend config update.The current error handling catches all errors generically. Consider more specific error handling and validation.
try { + const configPath = './update-frontend-config.js'; + if (!fs.existsSync(configPath)) { + throw new Error('Frontend config script not found'); + } const { updateFrontendConfig } = require('./update-frontend-config.js'); + if (typeof updateFrontendConfig !== 'function') { + throw new Error('updateFrontendConfig is not a function'); + } updateFrontendConfig(); + console.log("Frontend configuration updated successfully!"); } catch (error) { - console.error("Failed to update frontend config:", error.message); + console.error("Failed to update frontend config:", error.message); + console.error("Error details:", error); console.log("You can manually run: node scripts/update-frontend-config.js"); }
12-15: Add deployment verification.Consider adding verification that the contracts were deployed successfully before proceeding.
const financialPlatform = await FinancialPlatform.deploy(); await financialPlatform.waitForDeployment(); const platformAddress = await financialPlatform.getAddress(); + + // Verify deployment + const deployedCode = await ethers.provider.getCode(platformAddress); + if (deployedCode === '0x') { + throw new Error('FinancialPlatform deployment failed - no code at address'); + } + console.log("FinancialPlatform deployed to:", platformAddress);frontend/src/components/users/RegisterUserForm.tsx (2)
28-50: Consider moving roleOptions outside component for performance.The
roleOptionsarray is being recreated on every render. Since it's static data, it should be moved outside the component.+ const roleOptions = [ + { + value: UserRole.Regular, + label: 'Regular User', + description: 'Basic platform access', + icon: User, + color: 'bg-gray-100 text-gray-800 border-gray-200', + }, + // ... rest of the options + ]; + export function RegisterUserForm({ isOpen, onClose }: RegisterUserFormProps) { - const roleOptions = [ - // ... options array - ];
86-89: Simplify role selection handler.The role selection logic is correct, but could be slightly simplified by using the form's
setValuetrigger option.const handleRoleSelect = (role: UserRole) => { setSelectedRole(role); - setValue('role', role); + setValue('role', role, { shouldValidate: true }); };This will trigger validation immediately when a role is selected.
frontend/src/app/page.tsx (1)
12-18: Apply consistent loading state improvement.As with the other pages, consider using the shared
LoadingScreencomponent suggested earlier for consistency across the application.if (isInitializing) { return ( - <div className="min-h-screen bg-gray-50 flex items-center justify-center p-4"> - <p>Loading...</p> - </div> + <LoadingScreen message="Loading dashboard..." /> ); }frontend/src/components/settings/SoundSettings.tsx (1)
115-126: Consider adding user-facing error feedback.While the error handling logs to console, users won't be aware if a sound test fails. Consider showing a toast notification on error.
const handleTestSound = async (type: NotificationSoundType, playFunction: () => Promise<void>) => { if (!isEnabled) return; setTestingSound(type); try { await playFunction(); } catch (error) { console.error('Failed to test sound:', error); + toast.error('Failed to play sound. Please check your browser settings.'); } finally { setTimeout(() => setTestingSound(null), 500); } };frontend/src/lib/web3/config.ts (1)
44-48: Consider documenting the role hash origins.While the role names are self-explanatory, it would be helpful to document that these are keccak256 hashes of the role names for future maintainers.
+// Role hashes are keccak256 hashes of role names used in the smart contract +// ADMIN_ROLE: keccak256("ADMIN_ROLE") +// APPROVER_ROLE: keccak256("APPROVER_ROLE") +// USER_ROLE: keccak256("USER_ROLE") export const ROLE_HASHES = { ADMIN_ROLE: '0xa49807205ce4d355092ef5a8a18f56e8913cf4a201fbe287825b095693c21775', APPROVER_ROLE: '0x65d7a28e3265b37a6474929f336521b332c1681b933f6cb9f3376673440d862a', USER_ROLE: '0x2db9fd3d099848027c2383d0a083396f6c41510d7acfd92adc99b6cffcf31e96', } as const;frontend/src/lib/validations/transaction.ts (2)
19-26: Consider using a more precise number parsing method for amounts.The current implementation uses
parseFloatwhich may lose precision for very large numbers or numbers with many decimal places. Since this is handling financial amounts, precision is critical.Consider using a more robust validation approach:
.refine((value) => { try { - const parsed = parseFloat(value); - return parsed > 0; + // First check if it's a valid number format + if (!/^\d*\.?\d+$/.test(value.trim())) return false; + // Then verify it can be parsed by ethers + const parsed = ethers.parseEther(value); + return parsed > 0n; } catch { return false; } - }, 'Amount must be greater than 0') + }, 'Amount must be a valid positive number')This approach validates the format first and uses ethers' parsing to ensure the value is valid for blockchain operations.
8-14: Add validation for checksummed addresses.While
ethers.isAddressvalidates the address format, it accepts both checksummed and non-checksummed addresses. For better security, consider enforcing checksummed addresses..refine((value) => { try { - return ethers.isAddress(value); + if (!ethers.isAddress(value)) return false; + // Optionally enforce checksummed addresses + return ethers.getAddress(value) === value; } catch { return false; } - }, 'Invalid Ethereum address'), + }, 'Invalid Ethereum address (must be checksummed)'),frontend/src/components/users/UserList.tsx (2)
33-53: Consider using type-safe role comparisons.The code uses
Number(role)conversions throughout. Consider creating utility functions for type-safe role checks.Add these utility functions at the top of the file:
const isAdminRole = (role: UserRole | number): boolean => { return Number(role) === UserRole.Admin; }; const isManagerRole = (role: UserRole | number): boolean => { return Number(role) === UserRole.Manager; }; const isRegularRole = (role: UserRole | number): boolean => { return Number(role) === UserRole.Regular; }; const getRoleInfo = (role: UserRole | number) => { if (isAdminRole(role)) { return { label: 'Administrator', icon: Crown, color: 'bg-red-100 text-red-800 border-red-200', }; } if (isManagerRole(role)) { return { label: 'Manager', icon: Shield, color: 'bg-blue-100 text-blue-800 border-blue-200', }; } return { label: 'Regular User', icon: UserIcon, color: 'bg-gray-100 text-gray-800 border-gray-200', }; };Then use these throughout the component for better type safety and readability.
Also applies to: 73-74, 86-96
66-377: Consider splitting this component into smaller, more focused components.The UserList component is quite large (300+ lines) and handles multiple responsibilities. This could impact maintainability.
Consider extracting these sub-components:
UserStatistics- Lines 172-199UserFilters- Lines 201-226UserCard- Lines 249-337EmptyState- Lines 231-245This would improve:
- Code reusability
- Testability
- Maintainability
- Performance (with React.memo on sub-components)
Example for UserCard:
interface UserCardProps { user: User; currentUserAddress?: string; onEditRole: (user: User) => void; } const UserCard = React.memo(({ user, currentUserAddress, onEditRole }: UserCardProps) => { const roleInfo = getRoleInfo(user.role); const RoleIcon = roleInfo.icon; const isCurrentUser = user.walletAddress.toLowerCase() === currentUserAddress?.toLowerCase(); return ( <div className="flex flex-col lg:flex-row lg:items-center lg:justify-between p-4 border rounded-lg hover:bg-gray-50 gap-4"> {/* ... rest of the user card JSX ... */} </div> ); });frontend/src/components/dashboard/Dashboard.tsx (2)
36-36: Remove unused 'trend' property from MetricCard interface.The
trendproperty is defined in the interface but never used in the component.icon: React.ElementType; - trend?: 'up' | 'down' | 'neutral'; }) {
205-209: Consider implementing proper error handling for dashboard metrics.Currently, errors are only logged to console. Consider showing a user-friendly error state or fallback UI.
// Handle permission errors gracefully if (metricsError) { - console.warn('Dashboard metrics error:', metricsError); + // Show a toast notification or error banner + console.error('Dashboard metrics error:', metricsError); + // Consider showing partial dashboard with available data + // or a retry button for the user }You might want to add a toast notification system or error boundary to handle these cases more gracefully.
frontend/src/components/users/UserRoleManager.tsx (1)
63-72: Add user feedback for role update errors.The error is only logged to console. Consider showing a user-friendly error message.
try { await updateUserRoleMutation.mutateAsync({ userAddress: user.walletAddress, newRole: selectedRole, }); setSelectedRole(null); onClose(); } catch (error) { console.error('Failed to update user role:', error); + // Show error to user via toast or alert + // Example: toast.error('Failed to update user role. Please try again.'); }Consider implementing a toast notification system or error alert to inform users when the role update fails.
frontend/src/components/transactions/TransactionList.tsx (2)
124-126: Improve error handling for user feedback.Errors are only logged to console. Users should be informed when actions fail.
} catch (error) { console.error('Failed to request approval:', error); + // Show user-friendly error message + // Example: toast.error('Failed to request approval. Please try again.'); } finally {Similar improvement needed for the
handleCompleteTransactionfunction. Consider implementing a toast notification system or error alerts.Also applies to: 136-139
53-353: Consider splitting this large component.Like UserList, this component handles multiple responsibilities and could benefit from being split into smaller components.
Consider extracting:
TransactionFilters- Search and filter controlsTransactionCard- Individual transaction displayTransactionActions- Action buttons for transactionsThis would improve maintainability and enable better performance optimization with React.memo.
frontend/src/context/WalletProvider.tsx (1)
303-305: Document the reason for the setup delayConsider adding a comment explaining why the 1-second delay is necessary for contract initialization.
console.log('🔄 Setting up blockchain event listeners...'); - // Small delay to ensure contract is properly initialized + // Small delay to ensure contract is properly initialized and provider is ready + // This prevents race conditions when the wallet connection is just established await new Promise(resolve => setTimeout(resolve, 1000));frontend/src/components/ErrorBoundary.tsx (1)
83-83: Consider using Next.js router for navigation consistency.Instead of directly manipulating
window.location.href, consider using Next.js router for better consistency with the SPA navigation pattern.Import the router at the top of the file:
+import { useRouter } from 'next/navigation';Since this is a class component, you'd need to create a wrapper component or convert the navigation button to use a Link component:
-<Button - onClick={() => window.location.href = '/'} +<Button + onClick={() => window.location.replace('/')}Alternatively, use
window.location.replace('/')to prevent adding to browser history when navigating from an error state.frontend/src/components/wallet/WalletConnect.tsx (1)
107-119: Simplify the role badge rendering logic.The IIFE (Immediately Invoked Function Expression) adds unnecessary complexity. Consider simplifying this.
-{(() => { - const roleInfo = getRoleInfo(user.role); - const RoleIcon = roleInfo.icon; - return ( - <Badge - variant="outline" - className={`${roleInfo.color} flex items-center gap-1`} - > - <RoleIcon className="h-3 w-3" /> - {roleInfo.label} - </Badge> - ); -})()} +{(() => { + const { icon: RoleIcon, color, label } = getRoleInfo(user.role); + return ( + <Badge + variant="outline" + className={`${color} flex items-center gap-1`} + > + <RoleIcon className="h-3 w-3" /> + {label} + </Badge> + ); +})()}Or even better, extract this to a variable before the JSX:
const roleInfo = user ? getRoleInfo(user.role) : null; const RoleIcon = roleInfo?.icon;Then in the JSX:
{roleInfo && RoleIcon && ( <Badge variant="outline" className={`${roleInfo.color} flex items-center gap-1`} > <RoleIcon className="h-3 w-3" /> {roleInfo.label} </Badge> )}frontend/src/components/approvals/ApprovalHistory.tsx (1)
119-135: Consider memoizing filtered results for better performance.The filtering logic runs on every render. For large datasets, consider memoizing the filtered results.
Add at the top of the component:
import { useMemo } from 'react';Then wrap the filtering logic:
const filteredApprovals = useMemo(() => { return approvals.filter((approval) => { // ... existing filter logic }); }, [approvals, filter, searchTerm]);This will prevent unnecessary recalculations when other state changes.
frontend/src/lib/sounds/notificationSounds.ts (1)
51-51: Consider making MIN_INTERVAL configurableThe 1-second minimum interval between sounds is hardcoded. Consider making this configurable through the constructor or a setter method to allow different rate limiting based on use cases.
frontend/src/hooks/useContract.ts (1)
271-289: Consider consistent cache invalidation strategyThe cache invalidation here uses
exact: falsewhich is good for broad invalidation. Consider applying the same pattern in other mutations likeuseCreateTransaction(lines 184-188) for consistency.frontend/src/lib/web3/provider.ts (2)
65-65: Consider removing or conditionalizing the console.log in production.Logging wallet addresses to console could be a privacy concern in production environments.
- console.log('Connected to account:', accounts[0]); + if (process.env.NODE_ENV === 'development') { + console.log('Connected to account:', accounts[0]); + }
74-77: Add comment to clarify disconnect behavior.The method only clears local references as MetaMask doesn't support programmatic disconnection.
async disconnect(): Promise<void> { + // Note: This only clears local references. MetaMask doesn't support programmatic disconnection. this.provider = null; this.signer = null; }frontend/src/lib/contracts/service.ts (1)
80-80: Use console.error for consistency.Other error handlers in this file use
console.error.- console.log('Error getting user:', error); + console.error('Error getting user:', error);frontend/src/types/index.ts (2)
1-6: Considerconst enumfor better tree-shaking (or switch to literal unions).The numeric
enumkeeps the reverse mapping object in the bundle.
If these values never need runtime reflection you can drop ~1 kB per enum by switching toconst enum(or a union such as'pending' | 'active' | …'), which the TS compiler will inline as plain numbers/strings.-export enum TransactionStatus { +export const enum TransactionStatus {Same applies to
ApprovalStatus,ApprovalType, andUserRole.
77-83: Avoid duplication by deriving the form type fromTransaction.
CreateTransactionFormre-declares three fields already present onTransaction.
Derive it instead to stay DRY and auto-sync when the base interface evolves.-export interface CreateTransactionForm { - to: string; - amount: string; - description: string; -} +export type CreateTransactionForm = Pick< + Transaction, + 'to' | 'amount' | 'description' +> & { + // keep string-amount if you rely on text input; + // otherwise change to `bigint` for consistency. +};

.gitignore (1)
87-88: PR title inconsistency with actual changesThe PR title "Fix chart" doesn't align with the comprehensive financial platform being introduced. The gitignore change itself is appropriate for excluding temporary task files.
Likely an incorrect or invalid review comment.
frontend/.gitignore (1)
1-42: Well-structured frontend gitignoreComprehensive coverage of all necessary ignore patterns for a Next.js TypeScript project with proper categorization and comments.
contracts/FinancialPlatform.sol (2)
198-198: Approval tracking implementation looks correctThe approval ID is properly added to the tracking array when a new approval is requested.
283-283: Frontend error handling forgetUsercovers unregistered usersThe two calls to
contractService.getUserinfrontend/src/context/WalletProvider.tsxare already wrapped intry/catch, logging the error and leavinguserasnull. This preserves the previous behavior of “no user” when an address isn’t registered:• In the initial fetch (around line XX)
• In therefreshUsercallback (around line YY)No additional changes are needed—unregistered addresses will continue to resolve to
nullon the frontend.frontend/postcss.config.mjs (1)
1-5: Standard PostCSS configuration for Tailwind CSSThe configuration is minimal but appropriate for Tailwind CSS integration with proper ES module syntax.
frontend/components.json (1)
6-12: Empty Tailwindconfigpath may break IDE tooling & CLI commands
"config": ""tells the Shadcn/CLI that there is no Tailwind config file, but the project appears to rely on Tailwind utilities. Point it at the actual config (e.g.tailwind.config.ts) or remove the key to let the default be discovered automatically.- "config": "", + "config": "tailwind.config.ts",frontend/src/components/ui/sonner.tsx (1)
6-23: Component implementation looks good, but inconsistent with PR title.The Toaster component is well-implemented with proper theme integration and CSS custom properties. However, this appears to be a notification system component, not chart-related functionality as suggested by the PR title "Fix chart".
Likely an incorrect or invalid review comment.
frontend/src/app/layout.tsx (2)
23-29: Provider nesting structure is well-organized.The nested provider structure follows best practices with ErrorBoundary as the outermost wrapper, followed by general Providers, and finally the WalletProvider. This ensures proper error handling and context availability throughout the app.
10-13: Metadata is appropriate but inconsistent with PR title.The metadata describes a "Web3-enabled financial transaction management system" which aligns with the AI summary but not with the PR title "Fix chart". This suggests the PR title may be misleading.
Likely an incorrect or invalid review comment.
frontend/src/components/ui/page-size-selector.tsx (1)
12-35: Component functionality is solid but unrelated to chart fixes.The PageSizeSelector component is well-implemented for pagination controls, but this doesn't appear to be chart-related functionality as suggested by the PR title "Fix chart".
Likely an incorrect or invalid review comment.
frontend/src/components/debug/EventListenerStatus.tsx (2)
14-16: Early return pattern is appropriate.The early return when not connected prevents unnecessary rendering and is a good practice for conditional components.
9-58: Component is well-implemented but seems misplaced and unrelated to chart fixes.The EventListenerStatus component provides good real-time status feedback, but:
- It's in a "debug" folder yet appears to be a user-facing feature
- This doesn't relate to chart functionality as suggested by the PR title "Fix chart"
Consider moving this to a more appropriate folder like
components/statusorcomponents/wallet.Likely an incorrect or invalid review comment.
frontend/tsconfig.json (1)
1-27: TypeScript configuration is well-structured but unrelated to chart fixes.The tsconfig.json follows Next.js best practices with proper path aliases and modern options. However, this appears to be a general frontend setup rather than chart-specific fixes as suggested by the PR title "Fix chart".
Likely an incorrect or invalid review comment.
scripts/deploy.js (6)
88-89: LGTM! Descriptive transaction data improves test quality.Adding descriptive strings to the createTransaction calls makes the test data more realistic and helps with debugging and demonstration purposes.
96-97: Good practice: Using realistic test data.The "Invoice #123" description provides meaningful context for the transaction, which is helpful for testing and demo scenarios.
107-108: Consistent with the pattern established above.The "Office supplies" description continues the pattern of providing meaningful transaction contexts.
116-124: Good enhancement: Adding context to approval requests.The descriptive messages for approval requests ("Please approve payment", "Urgent approval needed", "Standard approval") provide valuable context that would be useful in a real application scenario.
132-136: Excellent: Realistic approval processing with reasons.Providing specific reasons for approval decisions ("Approved", "Rejected: Invalid invoice") demonstrates proper usage of the approval system and creates more realistic test data.
176-185: Good automation with proper error handling.The automatic frontend configuration update is a nice touch that streamlines the deployment process. The error handling is appropriate - it logs the error and provides manual fallback instructions without breaking the deployment.
frontend/src/lib/providers.tsx (3)
19-27: Excellent error-specific retry logic.The custom retry logic properly handles wallet connection errors and user registration issues by preventing unnecessary retries. This is exactly the right approach for Web3 applications where certain errors are definitive.
30-38: Smart mutation retry strategy for blockchain interactions.The mutation retry logic correctly identifies blockchain transaction failures that shouldn't be retried (execution reverted, user rejected). This prevents unnecessary gas costs and improves user experience.
9-42: Correct pattern: Stable QueryClient instance.Using useState with a factory function ensures the QueryClient instance remains stable across re-renders, which is the recommended pattern for React Query setup.
frontend/src/components/ui/input.tsx (1)
7-21: Well-implemented reusable Input component.The component follows React best practices:
- Proper use of
forwardReffor ref forwarding- Comprehensive TypeScript typing
- Good use of the
cnutility for className composition- Includes all necessary accessibility and styling classes
The implementation is solid and ready for use across the application.
frontend/src/components/transactions/CreateTransactionForm.tsx (4)
27-35: Excellent form setup with validation.The react-hook-form configuration with Zod resolver and
onChangemode provides real-time validation feedback, which is great for user experience. The form structure is well-organized.
37-46: Good error handling pattern.The async submission handler properly awaits the mutation, resets the form, and closes the dialog on success. Error handling is delegated to the mutation hook, which is appropriate since it likely shows toast notifications.
48-53: Smart dialog state management.The
handleOpenChangefunction ensures the form is reset whenever the dialog is closed, preventing stale data from persisting between opens.
128-141: Excellent loading state implementation.The submit button properly shows loading state with a spinner and disables interaction during mutation. The combination of form validation (
!isValid) and loading state (isPending) for the disabled condition is perfect.scripts/update-frontend-config.js (3)
11-24: Good error handling for missing files.The script properly checks for both the deployment info file and the .env.local file before proceeding, providing clear error messages and exiting gracefully when files are missing.
43-48: Excellent user feedback and guidance.The success messages clearly show what was updated and provide helpful guidance about restarting the frontend. This makes the script user-friendly and informative.
51-55: Good module pattern for reusability.The script can be run directly or imported as a module, which is exactly how it's used in the deployment scripts. This is a clean, reusable design.
frontend/src/app/globals.css (1)
124-132: Good solution for toast readability issues.The Sonner toast description styling fix addresses a common UX issue with proper dark mode support.
frontend/src/components/ui/textarea.tsx (1)
7-20: Well-implemented forwardRef component with good practices.The component follows React best practices with proper ref forwarding, type safety, and consistent styling. The className merging approach allows for customization while maintaining default styles.
frontend/src/app/users/page.tsx (1)
78-80: Good role checking implementation.The role checking logic here is clean and correct, using strict equality comparison. This is better than the Number() conversion pattern used in the approvals page.
frontend/src/components/users/RegisterUserForm.tsx (2)
69-78: Good error handling and cleanup logic.The submit handler properly handles the async operation, resets the form state, and closes the dialog on success. The error logging provides good debugging information.
196-202: Excellent user experience enhancement.The funding reminder is a thoughtful UX addition that helps administrators understand the complete user onboarding process. This kind of contextual help improves the overall user experience.
frontend/src/app/page.tsx (1)
9-84: Well-structured homepage with appropriate access flow.The component correctly handles the wallet connection and user registration flow without imposing role restrictions, which is appropriate for a homepage. The progressive disclosure of content based on wallet state is well implemented.
frontend/src/components/settings/SoundSettings.tsx (3)
1-29: Well-organized imports and proper client component setup.The imports are comprehensive and properly structured, with clear separation between React hooks, UI components, icons, and sound utilities.
30-91: Excellent sound type configuration structure.The SOUND_TYPES array provides a clean, data-driven approach with consistent metadata for each sound type, making the UI rendering logic more maintainable.
160-246: Excellent full mode UI implementation.The card-based layout provides clear organization with proper visual hierarchy, dynamic styling based on sound types, and helpful user information about rate limiting.
frontend/package.json (2)
1-10: Standard Next.js project configuration.The package metadata and scripts follow Next.js best practices with Turbopack enabled for improved development performance.
25-25: React 19 and Tailwind CSS v4 Compatibility Confirmed
- React 19.1.0 is the current stable release (released March 28, 2025).
- Tailwind CSS v4 is a valid stable major release (v4.0 on Jan 22, 2025; latest v4.1 released April 3, 2025).
No further changes are necessary.
frontend/src/lib/web3/config.ts (1)
16-42: Well-implemented configuration management.The getter functions provide proper validation and error handling for network and contract configurations, ensuring fail-fast behavior with clear error messages.
frontend/src/components/transactions/TransactionDetailsModal.tsx (3)
1-65: Well-structured imports and status configuration.The status configuration object provides excellent separation of concerns with comprehensive metadata for each transaction status.
115-269: Excellent dialog structure and user experience.The modal provides a well-organized layout with responsive design, copy functionality for important fields, and clear visual hierarchy.
271-331: Well-implemented action buttons with proper loading states.The action section provides clear user feedback with loading animations and appropriate disabled states during async operations.
frontend/src/components/ui/switch.tsx (2)
1-13: Clean interface definition with proper TypeScript types.The component interface includes all necessary props for a reusable switch component.
14-45: Excellent accessible switch implementation.The component properly implements ARIA attributes, keyboard accessibility, and smooth visual transitions. The use of forwardRef ensures compatibility with form libraries and ref-based APIs.
frontend/src/app/transactions/page.tsx (6)
1-1: Use client directive is correctly placed.The 'use client' directive is properly positioned at the top of the file, which is necessary for this interactive component that uses hooks and event handlers.
3-7: Clean and well-organized imports.The imports are logically grouped and follow a consistent pattern: context, components, and icons. The import paths use the proper alias structure.
9-18: Good loading state handling.The initialization check prevents rendering before wallet state is ready, providing a clean loading experience for users.
20-26: Proper wallet connection gating.The component correctly handles the disconnected state by showing the WalletConnect component, ensuring users can't access transactions without proper authentication.
28-73: Comprehensive unregistered user state handling.The registration required state is well-designed with clear messaging, next steps, and wallet address display. The UI is informative and guides users through the registration process.
75-84: Clean main content rendering.The main transactions page layout is simple and effective, with a clear header and the TransactionList component properly integrated within the AppLayout.
frontend/src/components/ui/button.tsx (4)
1-5: Well-structured imports and dependencies.The imports correctly include React, Radix UI Slot for composition, class-variance-authority for variants, and the utility function. All dependencies are properly typed.
7-36: Comprehensive variant configuration with accessibility features.The buttonVariants definition includes:
- Multiple visual variants (default, destructive, outline, secondary, ghost, link)

38-57: Solid component implementation with flexible composition.The Button component:
- Properly extends HTML button props with variant types
- Supports the asChild pattern for flexible composition
- Uses conditional rendering with Slot for advanced use cases
- Includes data attributes for testing/styling hooks
- Correctly merges className with variants using the cn utility
The implementation is robust and follows React best practices.
59-59: Proper exports for reusability.Exporting both the Button component and buttonVariants allows for flexible usage throughout the application - components can use the Button directly or apply the variant styles to other elements.
frontend/src/components/ui/badge.tsx (4)
1-5: Consistent import structure.The imports follow the same pattern as the Button component, maintaining consistency across UI components.
7-26: Well-designed badge variants with accessibility.The badgeVariants configuration includes:
- Comprehensive base styles with proper sizing, spacing, and typography
- Four distinct variants (default, secondary, destructive, outline) with appropriate color schemes
- Accessibility features including focus-visible rings and aria-invalid states
- SVG icon support with size constraints
- Hover states for interactive badges (using
[a&]selector for anchor wrapping)- Dark mode support and smooth transitions
The variant system is thorough and accessible.
28-44: Clean component implementation.The Badge component:
- Properly extends span element props with variant types
- Supports asChild pattern for flexible composition
- Uses data attributes for testing/styling hooks
- Correctly applies variant classes with className merging
The implementation is consistent with the Button component pattern.
46-46: Appropriate exports.Exporting both Badge and badgeVariants provides flexibility for direct usage and custom styling applications.
frontend/src/components/ui/pagination.tsx (5)
1-5: Proper imports and client directive.The imports correctly include the Button component, Lucide icons, and utility functions. The 'use client' directive is appropriate for this interactive component.
7-15: Well-defined TypeScript interface.The PaginationProps interface is comprehensive with clear types and includes an optional className for styling flexibility.
17-43: Robust pagination logic with proper edge case handling.The getVisiblePages function implements a sophisticated algorithm that:
- Uses a delta of 2 to show context around the current page
- Properly handles ellipsis placement for gaps
- Includes edge case handling for pages near the beginning and end
- Ensures page 1 and the last page are always accessible when appropriate
The logic correctly handles various pagination scenarios.
47-91: Excellent pagination UI with accessibility.The pagination rendering:
- Uses consistent Button components with proper variants
- Includes screen reader labels for navigation buttons
- Properly disables buttons at boundaries
- Renders ellipsis indicators appropriately
- Applies consistent styling and spacing
The accessibility features and user experience are well-implemented.
93-109: Useful pagination info component.The PaginationInfo component:
- Calculates item ranges correctly
- Handles edge cases properly with Math.min
- Provides clear, user-friendly text
- Includes proper TypeScript typing
This complement to the main pagination component enhances the user experience.
frontend/src/lib/validations/user.ts (4)
1-5: Proper imports and Ethereum address validation.The imports are correct and the Ethereum address regex pattern is accurate for validating 40-character hexadecimal addresses with '0x' prefix.
7-27: Comprehensive user registration validation.The registerUserSchema includes:
- Proper wallet address validation with Ethereum-specific regex
- Name validation with reasonable length constraints (2-50 characters)
- Email validation with format checking and length limits
- Role validation using UserRole enum bounds with integer constraints
- Clear, user-friendly error messages for all fields
The validation rules are appropriate for a user registration form.
29-39: Solid role update validation.The updateUserRoleSchema properly validates:
- User address with the same Ethereum validation as registration
- New role with the same constraints as registration
- Appropriate error messages
The schema is focused and appropriate for role management functionality.
41-42: Proper TypeScript type inference.The exported types are correctly inferred from the Zod schemas, providing type safety for form handling throughout the application.
frontend/src/components/dashboard/Dashboard.tsx (1)
194-194: Use the UserRole enum for consistency.Similar to the issue in RecentTransactions, use the enum value instead of hard-coding.
- const isAdmin = user && Number(user.role) === UserRole.Admin; + const isAdmin = user && Number(user.role) === UserRole.Admin;Wait, this line already uses the enum correctly. Let me re-check line 64.
Likely an incorrect or invalid review comment.
frontend/src/components/users/UserRoleManager.tsx (1)
187-189: Great implementation of contextual warnings!The dynamic warning messages based on role changes provide excellent user feedback about the implications of their actions.
frontend/src/components/transactions/TransactionList.tsx (1)
231-231: Prevent event propagation more elegantly.Good practice using
stopPropagation()to prevent row click when clicking buttons.frontend/src/lib/errors.ts (1)
14-212: Well-implemented error parsing with comprehensive coverageThe error parsing implementation is thorough and handles a wide variety of blockchain-specific error scenarios. The use of case-insensitive string matching and regex patterns for extracting revert reasons is practical and effective.
frontend/src/components/dashboard/DashboardChart.tsx (1)
1-184: Well-structured dashboard chart with proper role-based renderingThe component implementation is excellent with:
- Comprehensive state handling (loading, error, success)
- Clean role-based data configuration

Verify role type conversion and improve role checking logic.
The Number(user.role) conversion suggests uncertainty about the user.role type. If user.role is already of type UserRole (which should be a number enum), the conversion is redundant.
Consider this more explicit approach:
- if (!(Number(user.role) === UserRole.Manager || Number(user.role) === UserRole.Admin)) {
+ if (user.role !== UserRole.Manager && user.role !== UserRole.Admin) {Or use an array for better maintainability:
