|
||||
|
||||
### Option 2: Implement Custom Bridge
|
||||
|
||||
#### Architecture
|
||||
|
||||
```
|
||||
┌─────────────┐ ┌──────────────┐ ┌─────────────┐
|
||||
│ ChainID 1 │ ──────► │ Bridge Router│ ◄────── │ ChainID │
|
||||
│ (Ethereum) │ │ │ │ 138 │
|
||||
└─────────────┘ └──────────────┘ └─────────────┘
|
||||
│
|
||||
▼
|
||||
┌──────────────┐
|
||||
│ Validators │
|
||||
│ / Relayers │
|
||||
└──────────────┘
|
||||
```
|
||||
|
||||
#### Components
|
||||
|
||||
1. **Lockbox Contract** (ChainID 138)
|
||||
- Locks tokens on source chain
|
||||
- Emits lock events
|
||||
- Handles unlocks
|
||||
|
||||
2. **Inbox Contract** (Destination Chain)
|
||||
- Receives bridge messages
|
||||
- Mints/burns tokens
|
||||
- Validates messages
|
||||
|
||||
3. **Bridge Router**
|
||||
- Routes messages between chains
|
||||
- Validates transactions
|
||||
- Manages liquidity
|
||||
|
||||
4. **Relayer Network**
|
||||
- Monitors lock events
|
||||
- Submits unlock transactions
|
||||
- Provides redundancy
|
||||
|
||||
#### Implementation Steps
|
||||
|
||||
1. **Deploy Contracts**:
|
||||
```bash
|
||||
# Deploy Lockbox on ChainID 138
|
||||
forge script script/bridge/DeployLockbox.s.sol --rpc-url $RPC_URL_138
|
||||
|
||||
# Deploy Inbox on destination chain
|
||||
forge script script/bridge/DeployInbox.s.sol --rpc-url $DEST_RPC
|
||||
```
|
||||
|
||||
2. **Configure Bridge**:
|
||||
- Set up relayer network
