<Bridge
  clientId="542981292d51ec610388ba8985f027d7"
  fromChain={138}
  toChain={1}
  fromToken="0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"
  toToken="0xdAC17F958D2ee523a2206206994597C13D831ec7"
/>
```

**Installation**:
```bash
npm install @thirdweb-dev/react @thirdweb-dev/sdk
```

**Documentation**: [Bridge Widget](https://portal.thirdweb.com/bridge/widget)

## If Token Not Recognized

**Request Token Support** (per [Bridge FAQ](https://portal.thirdweb.com/bridge/faq)):

1. Go to Bridge tab in project dashboard
2. Settings → "Don't see your token listed?"
3. Submit:
   - Chain: Defi Oracle Meta Mainnet (138)
   - Token: `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
4. Wait 20-40 minutes for route discovery

**Requirements**:
- ✅ Token must have sufficient liquidity
- ✅ Token must be on supported chain (ChainID 138 ✅)

---

## Alternative: CCIP Bridge

**If thirdweb Bridge route not available** (e.g., token not recognized, no liquidity):

**Use CCIP Bridge**:
- Contract: `0x89dd12025bfCD38A168455A44B400e913ED33BE2`
- Supports ChainID 138
- Already deployed and configured
