298-303: Consider expanding the token metadata and making it more maintainable.The current implementation only includes SOL and USDC tokens, which may be limiting for a swap platform. Consider the following improvements:
- Expand token coverage: Add more commonly traded tokens
- External metadata source: Consider fetching metadata from a token registry or API
- Type safety: Add proper TypeScript interfaces
Here's a suggested improvement:
+interface TokenMetadata { + symbol: string; + name: string; + logoURI?: string; // Optional for future use +} + // Mapping tokens by addresses -const TOKEN_METADATA: Record<string, { symbol: string; name: string }> = { +const TOKEN_METADATA: Record<string, TokenMetadata> = { 'So11111111111111111111111111111111111111112': { symbol: 'SOL', name: 'Solana' }, 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v': { symbol: 'USDC', name: 'USD Coin' }, - // Add other tokens if necessary. - mainnet.json + // Add more popular tokens: + 'Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB': { symbol: 'USDT', name: 'Tether USD' }, + 'mSoLzYCxHdYgdzU16g5QSh3i5K3z3KZK7ytfqcJm7So': { symbol: 'mSOL', name: 'Marinade staked SOL' }, };

256-258: LGTM! Clean metadata retrieval with proper fallback.The implementation correctly retrieves token metadata with a sensible fallback to 'UNKNOWN' values when metadata is not found.
261-267:❓ Verification inconclusive
Verify Token constructor signature supports the new parameters.
The code now passes
symbolandnameparameters to the Token constructor. Please ensure the Raydium SDK's Token constructor accepts these additional parameters in this order.Also applies to: 269-275

Verify Token constructor signature in @raydium-io/raydium-sdk
Ensure theTokenclass’s constructor in the Raydium SDK accepts the extrasymbolandnameparameters (in the order:programId, mint, decimals, symbol, name). You can confirm this by inspecting the SDK’s type declarations (e.g.node_modules/@raydium-io/raydium-sdk/dist/index.d.ts) or its source on GitHub.• File:
src/RaydiumSwap.ts(lines 261–267 & 269–275)
