MetaMask Integration - Final Status Report

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

Date: 2026-01-27
Verification: Complete

✅ Verification Complete

Summary

All aspects of MetaMask integration have been verified:

  1. ✅ Decimals - Correct in token lists
  2. ✅ Balances - ERC-20 functions working
  3. ✅ Oracle Pricing - Updated successfully
  4. ⚠️ MetaMask Pricing - Requires CoinGecko (limitation, not error)
  5. ⚠️ Volumes - Oracles don't provide (limitation, not error)

📊 Detailed Results

1. Decimals ✅

Status: ✅ ALL CORRECT

  • WETH9: Token list has 18 (overrides contract's 0)
  • WETH10: Both contract and list have 18
  • cUSDT: Both contract and list have 6
  • cUSDC: Both contract and list have 6

Result: MetaMask will display balances correctly when using token lists.

2. Balances ✅

Status: ✅ WORKING

  • All balanceOf() functions operational
  • All allowance() functions operational
  • Balance queries succeed

Result: Balances will display correctly in MetaMask.

3. Pricing ⚠️

Oracle Status

  • ✅ Oracle Updated: Transaction 0x8f2f7760b887c4e5449e7c11ae0b63449962770c7d7ec97b20ca360da0144e1b
  • ✅ Price Sent: $2999.66 (299966000000 in 8 decimals)
  • ✅ Transaction Confirmed: Block 1463361
  • ✅ Status: Success

MetaMask Limitation

⚠️ IMPORTANT: MetaMask does NOT automatically query oracle contracts.

MetaMask Price Sources:

  1. CoinGecko API (primary) - requires token listing
  2. Token Lists - limited price metadata support
  3. Oracle Contracts - ❌ NOT automatically queried

Current Status:

  • ✅ Oracle has ETH/USD price data
  • ❌ cUSDT/cUSDC not on CoinGecko → no USD display in MetaMask
  • ✅ dApps can query oracle directly

Action Required:

  • Submit cUSDT and cUSDC to CoinGecko
  • See: docs/04-configuration/coingecko/COINGECKO_SUBMISSION_GUIDE.md

4. Volumes ⚠️

Status: ⚠️ ORACLES DON'T PROVIDE VOLUME DATA

Finding:

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

Action Required:

  • Submit tokens to CoinGecko (includes volume data)

🔧 Scripts and Tools

Created Scripts

  1. MetaMask Integration Check:

    ./smom-dbis-138/scripts/check-metamask-integration.sh
    • Verifies decimals, balances, pricing, volumes
    • Checks token list integration
    • Verifies oracle status

  2. Oracle Update:

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

  3. Oracle Publisher Status:

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

📋 Complete Checklist

✅ Working Correctly

  • Token decimals correct in token lists
  • WETH9 decimals fixed via token list
  • cUSDT/cUSDC decimals correct (6)
  • Balance functions working
  • Token lists hosted and accessible
  • Oracle contract updated successfully
  • Transaction confirmed

⚠️ Expected Limitations

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

🎯 Key Takeaways

✅ What's Working

  1. Decimals are correct - Token lists override on-chain values
  2. Balances display correctly - ERC-20 functions operational
  3. Oracle updated - Price feed has current data
  4. Token lists accessible - Hosted and properly configured

⚠️ Important Limitations

  1. MetaMask doesn't use oracles - Uses CoinGecko API instead
  2. USD pricing requires CoinGecko - No workaround for native MetaMask
  3. Volumes don't come from oracles - Oracles don't provide volume data

✅ Solutions Available

  1. Oracle updates - Script available and working
  2. CoinGecko submissions - Documents prepared
  3. dApp integration - Can query oracle directly

✅ Final Status

Decimals: ✅ CORRECT
Balances: ✅ WORKING
Oracle Pricing: ✅ UPDATED
MetaMask Pricing: ⚠️ REQUIRES COINGECKO
Volumes: ⚠️ REQUIRES COINGECKO

Overall: ✅ VERIFICATION COMPLETE

All critical checks passed. MetaMask will display decimals and balances correctly. For USD pricing and volumes, CoinGecko listing is required (expected limitation, not an error).
