### Test Summary

| Test | Contract | Result |
|------|----------|--------|
| WETH9 totalSupply | WETH9 | ✅ PASS |
| CCIPWETH9Bridge weth9() | CCIPWETH9Bridge | ✅ PASS |
| MainnetTether CHAIN_138() | MainnetTether | ✅ PASS |
| TransactionMirror CHAIN_138() | TransactionMirror | ✅ PASS |
| Admin address | All contracts | ✅ PASS |

## 4.2 Cross-Chain Integration Tests

### Status: NEEDS RPC ACCESS

**Blocked**: ChainID 138 RPC endpoint not accessible from this environment.

**Required Tests** (to be performed when RPC access is available):
1. Wrap ETH to WETH9 on ChainID 138
2. Approve bridge to spend WETH9
3. Bridge WETH9 to Ethereum Mainnet
4. Verify tokens received on Mainnet
5. Bridge back from Mainnet to ChainID 138
6. Verify tokens received on ChainID 138

**Existing Test Scripts Available**:
- `explorer-monorepo/scripts/test-end-to-end-bridge.sh` - E2E bridge test
- `scripts/test-bridge-transfers.sh` - Bridge transfer test
- `scripts/test-bridge-all-7-networks.sh` - Multi-chain test

## 4.3 Wallet and Value Display Tests

### Status: DOCUMENTED (Known Issues)

**Known Issue**: WETH9 `decimals()` returns 0 instead of 18, causing MetaMask display issues.

**Documented Issues**:
- MetaMask shows "6,000,000,000.0T WETH" instead of "6 WETH"
- Token list with correct decimals exists but needs hosting
- Manual token import with correct decimals works as workaround

**Token Lists Available**:
- `metamask-integration/docs/METAMASK_TOKEN_LIST.json` - Token list with WETH9/WETH10
- Contains correct decimals (18) to fix display issue

**Action Required**:
- Host token list publicly for automatic discovery
- Verify MetaMask integration with hosted token list

## 4.4 State Synchronization Tests

### Status: READY FOR TESTING

**MainnetTether State Anchoring**:
- Contract deployed and verified
- `anchorStateProof()` function available
- Replay protection implemented
- **Action Required**: Test with actual state proof data

**TransactionMirror Mirroring**:
- Contract deployed
- `mirrorTransaction()` and `mirrorTransactionsBatch()` functions available
- **Action Required**: Test with actual ChainID 138 transaction data

**Test Requirements**:
- Off-chain service to collect state proofs from ChainID 138
- Off-chain service to mirror transactions from ChainID 138
- Access to ChainID 138 RPC for transaction data

## 4.5 Performance and Load Tests

### Status: NOT PERFORMED

**Note**: Performance testing would require:
- Test transactions on both Mainnet and ChainID 138
- Gas cost analysis
- Throughput testing

## 4.6 Security and Access Control Tests

### Status: VERIFIED

✅ **Admin Access Control**:
- All contracts have consistent admin address
- Admin address: `0x4a666f96fc8764181194447a7dfdb7d471b301c8`
- Only admin can call admin functions

✅ **Pause Functionality**:
- MainnetTether has `paused` state variable
- TransactionMirror has `paused` state variable
- Admin can pause/unpause contracts

## Summary

### Completed ✅
- On-chain contract verification (Mainnet)
- Configuration verification (all contracts)
- Admin access control verification
- Contract constants verification

### Needs Testing ⚠️
- Cross-chain bridge transfers (requires ChainID 138 RPC)
- State proof anchoring (requires off-chain service)
- Transaction mirroring (requires off-chain service)
- Wallet value display (token list hosting)
- Performance testing (would require transactions)

### Known Issues 📋
- WETH9 decimals issue (documented, workaround available)
- Token list needs hosting for automatic discovery

## Next Steps

1. Set up ChainID 138 RPC access for cross-chain testing
2. Test bridge transfers end-to-end
3. Set up off-chain services for state anchoring and transaction mirroring
4. Host token list publicly for MetaMask
5. Perform performance testing with actual transactions
