222-225: Consider adding maximum decimal places validationWhile the numeric validation is good, cryptocurrency amounts often have restrictions on the maximum number of decimal places allowed.
Consider enhancing the validation to include a maximum decimal places check:
// check if valid sendAmount.value if (!isNumeric(sendAmount.value)) { return false; } + const [, decimals] = sendAmount.value.split('.'); + if (decimals && decimals.length > selectedAsset.value.decimals!) { + return false; + }

222-225: Verify the validation coverage
Let's verify that numeric validation is consistently applied across all transaction-related computations.
Also applies to: 353-355, 540-542
✅ Verification successful
Numeric validation is consistently applied across transaction flows
The verification shows that numeric validation is properly implemented across all transaction providers:
- Ethereum provider validates using both
isNumericandisValidDecimalschecks - Solana, Polkadot, Kadena, and Bitcoin providers all implement
isValidDecimalschecks - All providers use
BigNumberfor safe numeric operations after validation - Amount values are properly validated before being used in calculations or transactions
The current implementation in the Ethereum provider at lines 222-225 follows the established pattern across the codebase.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for potential missing numeric validations in transaction-related computations
# Look for direct usage of amount.value without validation
rg -A 5 "amount\.value" --type vue
# Look for potential arithmetic operations that might need validation
ast-grep --pattern 'computed(() => {
$$$
return $_ + $_;
})'
# Look for BigNumber operations that might need validation
rg "new BigNumber\(" --type vue
Length of output: 193
Script:
#!/bin/bash
# Search for numeric validation patterns and amount-related computations
rg -g '*.{vue,js,ts}' -A 5 "amount\.value|sendAmount\.value"
# Look for BigNumber operations
rg -g '*.{vue,js,ts}' "new BigNumber\("
# Look for isNumeric usage
rg -g '*.{vue,js,ts}' "isNumeric"

222-226: Add user feedback for invalid amount inputsWhile the validation is correct, consider providing user feedback when an invalid amount is entered.

583-597: Prevent race conditions in name resolutionThe debounced name resolution could lead to race conditions where a later request completes before an earlier one, potentially setting an incorrect address.

224-227: Consider adding explicit error handlingWhile the validation using
isNumericPositiveis good, silently returning 0 for invalid values might mask errors from users. Consider adding explicit error feedback through the UI.if (!isNumericPositive(sendAmount.value)) { + // Emit an error event or update an error state + emit('update:error', 'Please enter a valid positive number'); return toBN(0); }
Line range hint
441-557: Consider refactoring sendAction for better maintainabilityThe
sendActionmethod is handling multiple responsibilities including:
- Transaction preparation
- Fee calculation
- Hardware wallet detection
- Navigation logic
Consider breaking this down into smaller, focused methods for better maintainability and testing.
Example refactor:
+ const prepareTxInfo = (accountUTXOs, isSendToken) => { + // Extract transaction preparation logic + } + const calculateOutputs = (txInfo, toAmount, remainder) => { + // Extract output calculation logic + } + const handleHardwareWallet = async (txVerifyInfo) => { + // Extract hardware wallet logic + } const sendAction = async () => { const keyring = new PublicKeyRing(); const fromAccountInfo = await keyring.getAccount(addressFrom.value); // Use extracted methods const txInfo = await prepareTxInfo(accountUTXOs.value, isSendToken.value); const outputs = calculateOutputs(txInfo, toAmount, remainder); if (fromAccountInfo.isHardware) { await handleHardwareWallet(txVerifyInfo); } else { router.push(routedRoute); } };packages/extension/src/providers/kadena/ui/send-transaction/index.vue (3)
241-246: Remove debugging console.log statementThe console.log statement appears to be debugging code that should be removed before merging.
if (!isNumericPositive(amount.value)) { - console.log('amount', amount.value, !isNumericPositive(amount.value)); fieldsValidation.value.amount = false; errorMsg.value = 'Invalid amount. Amount has to be greater than 0'; return; }
241-246: Consider reordering validation checksThe positive number validation should come after the decimal places validation to provide more accurate error messages. If a user enters a negative number with too many decimal places, they'll first see the "greater than 0" error before seeing the decimal places error.
- if (!isNumericPositive(amount.value)) { - fieldsValidation.value.amount = false; - errorMsg.value = 'Invalid amount. Amount has to be greater than 0'; - return; - } if (!isValidDecimals(amount.value, selectedAsset.value.decimals!)) { fieldsValidation.value.amount = false; errorMsg.value = `Amount cannot have more than ${selectedAsset.value.decimals} decimals`; return; } + if (!isNumericPositive(amount.value)) { + fieldsValidation.value.amount = false; + errorMsg.value = 'Invalid amount. Amount has to be greater than 0'; + return; + }
241-246: Enhance error message clarityThe error message could be more specific about acceptable values, especially since there's a minimum amount check later in the code (0.000001).
if (!isNumericPositive(amount.value)) { fieldsValidation.value.amount = false; - errorMsg.value = 'Invalid amount. Amount has to be greater than 0'; + errorMsg.value = 'Invalid amount. Please enter a positive number (minimum 0.000001)'; return; }packages/extension/src/providers/polkadot/ui/send-transaction/index.vue (3)
462-465: Consider simplifying the amount validationThe current implementation can be made more concise while maintaining the same functionality.
- const checkedValue = amount.value?.toString() ?? '0'; - const rawAmount = toBN( - toBase( - isNumericPositive(checkedValue) ? checkedValue : '0', - selectedAsset.value.decimals ?? 0, - ), + const rawAmount = toBN( + toBase( + isNumericPositive(amount.value?.toString() ?? '0') ? amount.value : '0', + selectedAsset.value.decimals ?? 0, + ),
489-491: Consider optimizing validation orderThe current validation might attempt to check
isNumericPositiveon an undefined value. Consider reordering the conditions for better efficiency.if ( - amount.value !== undefined && amount.value !== '' && + amount.value !== undefined && isNumericPositive(amount.value) &&
Line range hint
202-490: Consider centralizing validation logicThe validation for positive numeric values is currently duplicated across multiple computed properties and methods. Consider extracting this into a single computed property that other parts of the component can reference.
Example approach:
const isValidAmount = computed(() => { return amount.value !== undefined && amount.value !== '' && isNumericPositive(amount.value); });This would:
- Reduce code duplication
- Make validation changes easier to maintain
- Ensure consistent validation behavior
packages/extension/src/providers/ethereum/ui/send-transaction/index.vue (3)
356-358: Ensure consistent validation approach.The validation in
nativeBalanceAfterTransactionuses a local variable as a fallback, which is good. However, this approach differs from other validations in the component.Consider extracting a common validation function:
+const getValidAmount = (value: string) => { + return isNumericPositive(value) ? value : '0'; +}; // In nativeBalanceAfterTransaction -const locAmount = isNumericPositive(amount.value) ? amount.value : '0'; +const locAmount = getValidAmount(amount.value);
500-500: Verify validation order in isInputsValid.The numeric validation is placed at the end of the validation chain. Consider moving it earlier to fail fast and avoid unnecessary validations.
const isInputsValid = computed<boolean>(() => { + if (!isNumericPositive(sendAmount.value)) return false; if (!props.network.isAddress(addressTo.value)) return false; if ( isSendToken.value && !isValidDecimals(sendAmount.value, selectedAsset.value.decimals!) ) { return false; } if (!isSendToken.value && !selectedNft.value.id) { return false; } if (new BigNumber(sendAmount.value).gt(assetMaxValue.value)) return false; if (gasCostValues.value.REGULAR.nativeValue === '0') return false; - if (!isNumericPositive(sendAmount.value)) return false; return true; });
Line range hint
1-800: Consider adding error messages for validation failures.The component performs various validations but doesn't provide specific error messages to users when validation fails. This could impact user experience.
Consider adding a computed property for validation error messages:
const validationError = computed(() => { if (!isNumericPositive(sendAmount.value)) return 'Please enter a valid positive amount'; if (!props.network.isAddress(addressTo.value)) return 'Invalid address'; if (new BigNumber(sendAmount.value).gt(assetMaxValue.value)) return 'Insufficient balance'; return ''; });

packages/extension/src/providers/ethereum/ui/send-transaction/index.vue (2)
171-174: LGTM: Import statement is correctly structured.
The import statement correctly includes both formatFloatingPointValue and isNumericPositive from the number formatter utility.
225-229: Verify edge cases in amount validation.
The numeric validation is good, but consider these edge cases:
- Scientific notation (e.g., "1e18")
- Numbers larger than
Number.MAX_SAFE_INTEGER - Extremely small numbers that could lead to precision loss
Consider using BigNumber.js for comprehensive validation:
- if (!isNumericPositive(sendAmount.value)) {
+ const amount = new BigNumber(sendAmount.value);
+ if (amount.isNaN() || !amount.isPositive() || amount.gt(new BigNumber(2).pow(256))) {
return false;
