MetaMask Integration Verification - Complete Report

Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation

Date: 2026-01-27
Status: ✅ Complete Verification Performed

📊 Verification Results Summary

Overall Status

  • ✅ Decimals: Correct in token lists
  • ✅ Balances: ERC-20 functions working
  • ⚠️ Pricing: Oracle updated, but MetaMask uses CoinGecko
  • ⚠️ Volumes: MetaMask doesn't get volumes from oracles

✅ 1. Decimals Verification

Status: ✅ ALL CORRECT

Token On-Chain Token List Status
WETH9 0 ❌ 18 ✅ Fixed via token list
WETH10 18 ✅ 18 ✅ Correct
cUSDT 6 ✅ 6 ✅ Correct
cUSDC 6 ✅ 6 ✅ Correct

Finding: Token lists correctly override on-chain decimals. MetaMask will use token list decimals.

✅ 2. Balance Display

Status: ✅ WORKING

  • All balanceOf() functions work correctly
  • Balance queries succeed
  • Display will be correct when using token lists

⚠️ 3. Pricing Status

Oracle Update

Transaction: 0x8f2f7760b887c4e5449e7c11ae0b63449962770c7d7ec97b20ca360da0144e1b
Status: ✅ Transaction confirmed in block 1463361
Price: $2999.66 (299966000000 in 8 decimals)

MetaMask Limitation

⚠️ CRITICAL: MetaMask does NOT automatically query oracle contracts.

MetaMask Price Sources:

  1. CoinGecko API (primary) - requires token listing
  2. Token Lists - limited support
  3. Oracle Contracts - ❌ NOT used by MetaMask

Current Status:

  • ✅ Oracle has price data (ETH/USD)
  • ❌ cUSDT/cUSDC not on CoinGecko → no USD display in MetaMask
  • ✅ Oracle can be used by dApps directly

Action Required:

  • Submit cUSDT and cUSDC to CoinGecko for MetaMask USD display

⚠️ 4. Volume Data

Status: ⚠️ ORACLES DON'T PROVIDE VOLUME DATA

Finding:

  • MetaMask doesn't display volume from oracles
  • Volume data comes from CoinGecko/external APIs
  • Oracle contracts don't provide volume data
  • Token aggregation service exists but MetaMask doesn't query it

Action Required:

  • Submit tokens to CoinGecko (includes volume data)

🔧 Scripts Created/Updated

  1. MetaMask Integration Check:

    • smom-dbis-138/scripts/check-metamask-integration.sh
    • Verifies decimals, balances, pricing, volumes

  2. Oracle Update Script:

    • smom-dbis-138/scripts/update-oracle-price.sh
    • ✅ Fixed RPC URL selection
    • ✅ Added transmitter authorization check
    • ✅ Uses aggregator address for updates
    • ✅ Successfully updated oracle

  3. Oracle Publisher Status:

    • smom-dbis-138/scripts/check-oracle-publisher-status.sh
    • Checks service status and configuration

📋 Complete Checklist Results

✅ Working

  • Decimals correct in token lists
  • Balances display correctly
  • ERC-20 functions operational
  • Token lists hosted and accessible
  • Oracle contract updated successfully
  • Transaction confirmed

⚠️ Limitations (Expected)

  • MetaMask USD pricing (requires CoinGecko)
  • MetaMask volume display (requires CoinGecko)
  • Oracle Publisher service (needs configuration)

🎯 Key Findings

1. Decimals ✅

  • Status: All correct
  • Solution: Token lists override on-chain decimals
  • Action: None needed

2. Balances ✅

  • Status: Working correctly
  • Solution: ERC-20 functions operational
  • Action: None needed

3. Pricing ⚠️

  • Oracle: ✅ Updated successfully
  • MetaMask: ⚠️ Uses CoinGecko, not oracles
  • Solution: Submit tokens to CoinGecko
  • Action: Use CoinGecko submission guide

4. Volumes ⚠️

  • Oracle: ❌ Doesn't provide volume data
  • MetaMask: ⚠️ Gets volumes from CoinGecko
  • Solution: Submit tokens to CoinGecko
  • Action: Use CoinGecko submission guide

✅ Conclusion

Decimals and Balances: ✅ FULLY WORKING

  • Token lists correctly configured
  • All functions operational
  • MetaMask will display correctly

Pricing and Volumes: ⚠️ REQUIRES COINGECKO LISTING
