## 🔍 Variable Naming Strategy

### Primary Naming (Network-Specific)
- Format: `{CONTRACT}_{NETWORK}`
- Examples: `CCIP_ROUTER_138`, `CCIPWETH9_BRIDGE_MAINNET`

### Alias Naming (Backward Compatibility)
- Format: `{CONTRACT}` (for ChainID 138)
- Examples: `LINK_TOKEN`, `CCIP_ROUTER_ADDRESS`, `WETH9_ADDRESS`

### Benefits
- ✅ Clear network identification
- ✅ Backward compatibility maintained
- ✅ Easy to find contracts by network
- ✅ Supports multi-network configurations

---

## ✅ Verification Results

### All Contracts Found
- ✅ All 13 ChainID 138 contracts in .env
- ✅ All 6 Ethereum Mainnet contracts in .env
- ✅ Total: 19/19 contracts (100% coverage)

### Variable Names
- ✅ Network-specific variables added (`_138`, `_MAINNET`)
- ✅ Alias variables maintained for backward compatibility
- ✅ All contracts accessible via multiple variable names

---

## 📄 Files Updated

1. ✅ `explorer-monorepo/.env`
   - Added all missing contracts from DEPLOYED_CONTRACTS_REVIEW.md
   - Added network-specific variable names
   - Maintained backward compatibility aliases

---

## 🔧 Issues Identified

### Critical
1. ⚠️ **CCIPReceiver** (ChainID 138)
   - Address: `0x95007eC50d0766162F77848Edf7bdC4eBA147fb4`
   - Status: In .env but needs re-deployment
   - Issue: Code size only 3 bytes (not actually deployed)
   - Action: Re-deploy contract

### Notes
- All other contracts are properly deployed and verified
- All addresses are now in .env files
- Variable naming is comprehensive and consistent
