## 1.3 Current Deployment Status Audit

### Ethereum Mainnet (Chain ID: 1)

| Contract | Address | Status | Bytecode Verified |
|----------|---------|--------|-------------------|
| CCIPWETH9Bridge | `0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6` | DEPLOYED | YES |
| CCIPWETH10Bridge | `0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e` | DEPLOYED | YES |
| MainnetTether | `0x15DF1D5BFDD8Aa4b380445D4e3E9B38d34283619` | DEPLOYED | YES |
| TransactionMirror | `0x4CF42c4F1dBa748601b8938be3E7ABD732E87cE9` | DEPLOYED | YES |
| TwoWayTokenBridgeL1 | TBD | NEEDS VERIFICATION | - |
| TwoWayTokenBridgeL2 | TBD | NEEDS VERIFICATION | - |
| MirrorManager | TBD | NEEDS VERIFICATION | - |
| CCIPLogger | TBD | NEEDS VERIFICATION | - |

### ChainID 138

| Contract | Address | Status | Notes |
|----------|---------|--------|-------|
| CCIPWETH9Bridge | `0x89dd12025bfCD38A168455A44B400e913ED33BE2` | NEEDS RPC VERIFICATION | RPC not accessible from test environment |
| CCIPWETH10Bridge | `0xe0E93247376aa097dB308B92e6Ba36bA015535D0` | NEEDS RPC VERIFICATION | RPC not accessible from test environment |
| WETH9 | `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2` | PREDEPLOYED | Genesis predeployment |
| WETH10 | `0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f` | PREDEPLOYED | Genesis predeployment |

**Note**: ChainID 138 RPC endpoint `http://192.168.11.250:8545` is not accessible from this environment. Verification will need to be performed in an environment with network access to ChainID 138.

## 1.4 Environment Configuration Check

### Status: PENDING VERIFICATION

Environment variables that need to be checked:

#### Mainnet Configuration
- `ETHEREUM_MAINNET_RPC` - Required
- `PRIVATE_KEY` - Required
- `ETHERSCAN_API_KEY` - Required
- `WETH9_MAINNET` - Should be `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
- `WETH10_MAINNET` - Should be `0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f`
- `CCIP_ROUTER_MAINNET` - Should be `0x80226fc0Ee2b096224EeAc085Bb9a8cba1146f7D`
- `LINK_TOKEN_MAINNET` - Should be `0x514910771AF9Ca656af840dff83E8264EcF986CA`

#### ChainID 138 Configuration
- `RPC_URL_138` or equivalent - Required
- `CCIP_ROUTER_138` - Required
- `LINK_TOKEN_138` - Required

#### Optional Deployment Admin Variables
- `TETHER_ADMIN` - Optional (defaults to deployer)
- `MIRROR_ADMIN` - Optional (defaults to deployer)
- `BRIDGE_L1_TOKEN` - Required for TwoWayBridge deployment
- `BRIDGE_L2_TOKEN` - Required for TwoWayBridge deployment

## 1.5 Ledger App-Ethereum Verification

### Status: VERIFIED (from previous search)

ChainID 138 is already configured in `app-ethereum`:

- `pr-workspace/app-ethereum/src/network.c` - Line 42: ChainID 138 entry exists
- `pr-workspace/app-ethereum/makefile_conf/chain/defi_oracle.mk` - Configuration file exists
- Test file `pr-workspace/app-ethereum/tests/ragger/test_get_address.py` - Line 24: Includes ChainID 138 in test params

**Configuration Details**:
- Chain ID: 138
- Name: "Defi Oracle Meta"
- Ticker: "ETH"

**Action Required**: Verify RPC endpoints in configuration match current infrastructure:
- Public: `https://rpc-http-pub.d-bis.org`
- Permissioned: `https://rpc-http-prv.d-bis.org`

## Next Steps

1. Verify `.env` file contains all required variables
2. Check if TwoWayTokenBridge contracts are deployed on Mainnet
3. Check if MirrorManager is deployed on Mainnet
4. Check if CCIPLogger is deployed on Mainnet
5. Verify ChainID 138 contracts when RPC access is available
6. Proceed to Phase 2: Pre-Deployment Testing
