# MetaMask Integration Verification Report
**Last Updated:** 2026-01-31
**Document Version:** 1.0
**Status:** Active Documentation
---
**Date:** 2026-01-27
**ChainID:** 138 (DBIS Chain)
**Status:** ✅ Verification Complete
---
## 📊 Executive Summary
**Results:**
- ✅ **Passed:** 20 checks
- ❌ **Failed:** 1 check (Oracle price data)
- ⚠️ **Warnings:** 5 (Expected limitations)
**Overall Status:** ✅ **Decimals and Balances Correct** | ⚠️ **Pricing/Volumes Need CoinGecko**
---
## ✅ 1. Decimals Verification
### Status: ✅ **CORRECT**
| Token | On-Chain | Token List | MetaMask List | Status |
|-------|----------|------------|---------------|--------|
| **WETH9** | 0 ❌ | 18 ✅ | 18 ✅ | ✅ Fixed via token list |
| **WETH10** | 18 ✅ | N/A | 18 ✅ | ✅ Correct |
| **cUSDT** | 6 ✅ | 6 ✅ | 6 ✅ | ✅ Correct |
| **cUSDC** | 6 ✅ | 6 ✅ | 6 ✅ | ✅ Correct |
### Key Finding
**WETH9 Issue Resolved:**
- Contract's `decimals()` returns `0` (known issue)
- Token lists override with correct `18` decimals ✅
- MetaMask will use token list decimals when available
**Recommendation:** ✅ No action needed - token lists correctly configured
---
## ✅ 2. Balance Display Verification
### Status: ✅ **WORKING**
**All tokens:**
- ✅ `balanceOf()` function works correctly
- ✅ Balance queries succeed
- ✅ Display depends on correct decimals (handled by token lists)
**Test Results:**
- ✅ cUSDC: balanceOf() works
- ✅ cUSDT: balanceOf() works
- ✅ WETH10: balanceOf() works
- ✅ WETH9: balanceOf() works
**Recommendation:** ✅ No action needed - balances display correctly
---
## ⚠️ 3. Pricing Verification
### Status: ⚠️ **ORACLE EXISTS BUT NOT USED BY METAMASK**
### Oracle Contract Status
- **Address:** `0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6`
- **Type:** ETH/USD Price Feed
- **Current Status:** ❌ Returns zero (needs price update)
- **Update Service:** Oracle Publisher (VMID 3500) - needs configuration
### MetaMask Price Source Reality
**⚠️ CRITICAL FINDING:** MetaMask does NOT automatically query oracle contracts.
**MetaMask Price Sources (in order):**
1. **CoinGecko API** - Primary source (requires token listing)
2. **Token Lists** - Limited price metadata support
3. **Oracle Contracts** - ❌ NOT automatically queried
### Current Token Status
| Token | CoinGecko Listed | USD Display in MetaMask |
|-------|------------------|-------------------------|
| **ETH** | ✅ Yes | ✅ Shows USD |
| **WETH9** | ❌ No | ❌ No USD (unless CoinGecko lists) |
| **WETH10** | ❌ No | ❌ No USD (unless CoinGecko lists) |
| **cUSDT** | ❌ No | ❌ No USD (needs CoinGecko listing) |
| **cUSDC** | ❌ No | ❌ No USD (needs CoinGecko listing) |
### Recommendations
1. **For Oracle (dApp Use):**
- ✅ Update oracle with current prices (script available)
- ✅ Oracle Publisher service needs to be running
- ✅ dApps can query oracle directly for USD values
2. **For MetaMask USD Display:**
- ⏳ Submit cUSDT and cUSDC to CoinGecko
- ⏳ Submit WETH9 and WETH10 to CoinGecko (if needed)
- ✅ Documentation prepared: `docs/04-configuration/coingecko/COINGECKO_SUBMISSION_GUIDE.md`
---
## ⚠️ 4. Volume Data Verification
### Status: ⚠️ **ORACLES DON'T PROVIDE VOLUME DATA**
### Key Finding
**MetaMask does NOT display volume data from oracles.**
**Volume Data Sources:**
- **CoinGecko API** - If token is listed
- **Token Lists** - Limited support
- **Oracle Contracts** - ❌ Do not provide volume data
- **Token Aggregation Service** - Exists but MetaMask doesn't query it
### Current Status
- ✅ Token aggregation service exists (`smom-dbis-138/services/token-aggregation`)
- ✅ Service can aggregate volume from multiple sources (CoinGecko, DexScreener, CMC)
- ⚠️ MetaMask doesn't query this service directly
- ⚠️ Volume data only available if tokens are on CoinGecko
### Recommendations
1. **For Volume Display in MetaMask:**
- ⏳ Submit tokens to CoinGecko (includes volume data)
- ⏳ Ensure tokens have trading activity for volume metrics
2. **For dApp Volume Display:**
- ✅ Token aggregation service can provide volume data
- ✅ dApps can query the service API directly
---
## 📋 Complete Verification Results
### ✅ Working Correctly
1. **Decimals:**
- ✅ Token lists have correct decimals
- ✅ WETH9 issue resolved via token list override
- ✅ cUSDT/cUSDC decimals correct (6)
- ✅ WETH10 decimals correct (18)
2. **Balances:**
- ✅ All ERC-20 functions work
- ✅ balanceOf() works for all tokens
- ✅ Display will be correct when using token lists
3. **Token Lists:**
- ✅ Hosted and accessible
- ✅ Correct decimals configured
- ✅ All tokens included
### ⚠️ Needs Attention
1. **Oracle Price Data:**
- ❌ Oracle returns zero (needs update)
- ⏳ Oracle Publisher service needs configuration
- ✅ Script available to update manually
2. **MetaMask USD Pricing:**
- ⚠️ MetaMask doesn't use oracles
- ⚠️ Requires CoinGecko listing
- ✅ Submission documents prepared
3. **Volume Data:**
- ⚠️ MetaMask doesn't get volumes from oracles
- ⚠️ Requires CoinGecko listing
- ✅ Aggregation service exists for dApps
---
## 🔧 Action Items
### Immediate (Can Do Now)
1. **Update Oracle Price:**
```bash
cd /home/intlc/projects/proxmox/smom-dbis-138
./scripts/update-oracle-price.sh
```
2. **Check Oracle Publisher Service:**
```bash
./scripts/check-oracle-publisher-status.sh
```
### Short-term (1-2 weeks)
1. **Submit to CoinGecko:**
- Review: `docs/04-configuration/coingecko/COINGECKO_SUBMISSION_GUIDE.md`
- Submit cUSDT and cUSDC
- This will enable USD pricing in MetaMask
2. **Configure Oracle Publisher:**
- Set up VMID 3500 service
- Configure automatic price updates
- Monitor service status
### Long-term
1. **Monitor CoinGecko Submissions:**
- Follow up on listing requests
- Verify USD prices appear in MetaMask after listing
2. **Maintain Oracle Updates:**
- Ensure Oracle Publisher stays running
- Monitor price freshness

## 📊 Summary Table
| Aspect | Status | MetaMask Source | Oracle Source | Action Needed |
|--------|--------|-----------------|---------------|---------------|
| **Decimals** | ✅ Correct | Token Lists | N/A | ✅ None |
| **Balances** | ✅ Working | On-chain | On-chain | ✅ None |
| **Pricing** | ⚠️ Limited | CoinGecko | Oracle (not used) | ⏳ CoinGecko listing |
| **Volumes** | ⚠️ Limited | CoinGecko | N/A (oracles don't provide) | ⏳ CoinGecko listing |
---
## 🎯 Key Takeaways
### ✅ What's Working
1. **Decimals are correct** - Token lists override incorrect on-chain decimals
2. **Balances display correctly** - ERC-20 functions work, token lists provide correct decimals
3. **Token lists are hosted** - Accessible and properly configured
### ⚠️ Important Limitations
1. **MetaMask doesn't use oracles** - Uses CoinGecko API instead
2. **Oracle needs price update** - Currently returns zero
3. **USD pricing requires CoinGecko** - No workaround for native MetaMask display
4. **Volumes don't come from oracles** - Oracles don't provide volume data
### ✅ Solutions Available
1. **Oracle updates** - Script available to update prices
2. **CoinGecko submissions** - Documents prepared and ready
3. **dApp integration** - Can query oracle directly for USD values
