## 🔍 Validation Methods

### 1. On-chain Bytecode Check

```bash
# Check contract has bytecode
cast code <ADDRESS> --rpc-url https://rpc-core.d-bis.org

# Expected: Non-empty hex string (not "0x")
```

### 2. Function Call Validation

```bash
# Example: Check Oracle latest price
cast call 0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6 \
  "latestRoundData()(uint80,int256,uint256,uint256,uint80)" \
  --rpc-url https://rpc-core.d-bis.org

# Example: Check CCIP Router fee
cast call 0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e \
  "getFee(uint64,bytes)" \
  <chain_selector> <data> \
  --rpc-url https://rpc-core.d-bis.org
```

### 3. Event Validation

```bash
# Check for recent events
cast logs --from-block latest --address <CONTRACT_ADDRESS> \
  --rpc-url https://rpc-core.d-bis.org
```

### 4. Blockscout Verification

```bash
# Check verification status via API
curl -s "https://explorer.d-bis.org/api/v2/smart-contracts/<ADDRESS>" | \
  jq '{address: .address, verified: .is_verified, name: .name}'
```

## 🚀 Next Actions

### Immediate (High Priority)

1. **Verify All Contracts on Blockscout**
   ```bash
   ./scripts/verify-all-contracts.sh
   ```

2. **Check Contract Bytecode**
   ```bash
   for addr in \
     0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6 \
     0x99b3511a2d315a497c8112c1fdd8d508d4b1e506 \
     0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e \
     0x105F8A15b819948a89153505762444Ee9f324684 \
     0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
     0xe0E93247376aa097dB308B92e6Ba36bA015535D0 \
     0xD3AD6831aacB5386B8A25BB8D8176a6C8a026f04; do
     echo "Checking $addr..."
     cast code $addr --rpc-url https://rpc-core.d-bis.org | head -c 20
     echo ""
   done
   ```

### Short-term (Medium Priority)

3. **Functional Testing**
   - Test each contract's core functionality
   - Verify constructor parameters
   - Test event emission

4. **Integration Testing**
   - Test service-to-contract interactions
   - Verify event monitoring
   - Test cross-chain message flow

### Documentation

5. **Update Documentation**
   - Update verification status
   - Document any issues found
   - Create validation report
