Code Review Progress

• Read repository guidelines (CLAUDE.md)
• Review token definition changes across all modified files
• Check consistency between different network implementations
• Verify adherence to existing patterns and conventions
• Provide comprehensive review feedback

Code Review Summary

I've completed a thorough review of the PR that adds SoFiUSD and USD1 token definitions across multiple blockchain networks. Here are my findings:

✅ Positive Aspects

1. Consistent Pattern Following: The implementation correctly follows established patterns for token definitions across all networks
2. Proper Network Coverage: Comprehensive coverage across mainnet and testnet for all supported networks
3. Correct Token Features: Appropriate use of CoinFeature.STABLECOIN for both SoFiUSD and USD1
4. Complete Implementation: All necessary files are updated (base enums, network-specific configs, OFC variants)

📋 Detailed Analysis by Network

SoFiUSD Token (6 decimals):

• ✅ Tempo: Added to both mainnet (tempo:sofid) and testnet (ttempo:sofid, ttempo:stgsofid)
• ✅ Monad: Added to both mainnet (mon:sofid) and testnet (tmon:sofid, tmon:stgsofid)
• ✅ Polygon: Added to both mainnet (polygon:sofid) and testnet (tpolygon:sofid, tpolygon:stgsofid)

USD1 Token (18 decimals):

• ✅ GasEVM: Added to both mainnet (gasevm:usd1) and testnet (tgasevm:usd1, tgasevm:stgusd1)

🔍 Technical Verification

1. Unique IDs: All token entries use proper UUID v4 format
2. Contract Addresses: All Ethereum addresses follow proper format (0x + 40 hex chars)
3. Decimals: Consistent across networks (SoFiUSD: 6, USD1: 18)
4. UnderlyingAsset Enum: All new assets properly added to base.ts:3210-4535
5. Feature Flags: Appropriate features applied (STABLECOIN, EVM_NON_BITGO_RECOVERY, etc.)

🏗️ Architecture Compliance

• OFC Support: Both tokens properly added to OFC (Off-Chain) variants
• Test Coverage: Both mainnet and testnet configurations included
• Staging Variants: Appropriate staging token variants (stg*) included for testnet

⚠️ Minor Observations

1. Contract Address Reuse: I notice some contract addresses appear to be reused between networks (e.g., SoFiUSD uses same address 0xa7171032d2f41828dffd793149823e13f79c456e on both tmon and tpolygon testnets). This is likely intentional for testing but worth confirming.

2. Network Consistency: The implementation correctly handles the different network architectures (EVM-compatible chains vs. Tempo's TIP-20 standard).

🎯 Recommendation

✅ APPROVED - This PR is well-implemented and follows all established patterns. The token definitions are complete, consistent, and properly structured across all target networks. No blocking issues identified.

The changes are ready for merge assuming the contract addresses are correct for each respective network.

Pull request overview

Adds new token metadata to @bitgo/statics for SoFiUSD and USD1 across several supported networks (Polygon, Tempo, Monad, and GasEVM / Neo X), ensuring the assets are available via the statics coin/token registries and OFC mappings.

Changes:

• Added SoFiUSD token definitions for Polygon (mainnet + testnet), Tempo (mainnet + testnet), and Monad (mainnet + testnet).
• Added USD1 token definitions for GasEVM (mainnet + testnet), including OFC ERC20 metadata.
• Extended UnderlyingAsset to include the new asset identifiers required by the new token entries.

Did we deployed the prod token ?,

The current prod explore is showing nothing

https://monadscan.com/token/0x5572728e36b5510010ade1db6bbaea1c402411cc#transactions

Can you check is this the correct prod contract

[zeeshanamjad-eng]

Not deployed, but the address is going to be the same, @sachushaji will deploy it
