## 🔗 **Chain-Specific Guides**

### **XDC Network (Chain ID 50)**

**Status**: ✅ Adapter Created

**Deployment Steps**:

1. Deploy XDCAdapter:
```bash
forge script script/deploy/adapters/DeployXDCAdapter.s.sol \
  --rpc-url https://rpc.xinfin.network \
  --broadcast \
  --private-key $PRIVATE_KEY
```

2. Register in ChainRegistry:
```solidity
chainRegistry.registerEVMChain(
    50,
    xdcAdapterAddress,
    "https://explorer.xdc.network",
    12,  // min confirmations
    2,   // avg block time
    ""   // additional data
);
```

**Special Notes**:
- XDC uses `xdc` prefix instead of `0x`
- Adapter includes conversion functions
- Very low fees (~0.001 XDC per tx)

---

### **ALL Mainnet**

**Status**: ✅ Adapter Created (Chain ID: 651940)

**Chain Information**:
- **Chain ID**: 651940 (0x9f2a4)
- **Network Name**: ALL Mainnet
- **Native Currency**: ALL (18 decimals)
- **RPC**: https://mainnet-rpc.alltra.global
- **Explorer**: https://alltra.global
- **ChainList**: https://chainlist.org/chain/651940

**Deployment Steps**:

1. ✅ Chain ID updated in `AlltraAdapter.sol` (651940)
2. ⚠️ Verify CCIP support via CCIP Directory
3. ⚠️ Verify LiFi support via LiFi API
4. Deploy adapter
5. Register in ChainRegistry

**Configuration Needed**:
- [x] Confirm ALL Mainnet Chain ID (651940)
- [x] Get RPC endpoint (https://mainnet-rpc.alltra.global)
- [x] Get block explorer URL (https://alltra.global)
- [ ] Verify CCIP chain selector (if supported)
- [ ] Verify USDC deployment on ALL Mainnet
- [ ] Update routing logic based on CCIP/LiFi support status

**Important**: Distinguish between:
- **ALL Mainnet** (chain, chainId 651940) - The EVM blockchain
- **ALLTRA** (orchestration layer) - The hybrid service layer

---

### **XRPL (XRP Ledger)**

**Status**: ✅ Adapter Created

**Deployment Steps**:

1. Deploy XRPLAdapter
2. Deploy Oracle Service (monitors XRPL transactions)
3. Register in ChainRegistry

**Oracle Service Requirements**:
- Monitor XRPL for bridge transactions
- Call `confirmXRPLTransaction()` on adapter
- Handle XRP drops conversion

**XRPL Features**:
- Destination tags (for exchanges)
- Very low fees (~0.000012 XRP)
- Fast finality (3-5 seconds)

**Infrastructure**: ✅ VMIDs 6202, 6203 deployed

**Deployment Steps**:

1. Initialize Firefly on VMID 6202:
```bash
ssh root@192.168.11.175
ff init alltra-bridge --multiparty
```

2. Connect to Besu (ChainID 138):
```bash
ff accounts create --key /path/to/besu/key.json
```

# firefly/config/firefly.core.yml
namespaces:
  predefined:
    - name: alltra-bridge
      plugins:
        blockchain:
          - ethereum:

## 🐛 **Troubleshooting**

### **Common Issues**

1. **Adapter Not Found**
   - Check ChainRegistry registration
   - Verify adapter address
   - Check adapter is active

2. **Oracle Not Confirming**
   - Check oracle service is running
   - Verify oracle has ORACLE_ROLE
   - Check event logs

3. **Firefly Not Responding**
   - Check Firefly service status
   - Verify namespace configuration
   - Check WebSocket connection
