## Integration Guidelines

### Using These Addresses

1. **CCTP Transfers:** Use Cashmere CCTP contracts + Domain IDs
2. **USDT0 Transfers:** Use USDT0 OFT contracts + LayerZero Endpoint IDs
3. **NEAR Intents:** Use Treasury contracts for BNB Chain routing
4. **Token Approvals:** Approve spending to Cashmere contracts before transfers

### Important Notes

* Domain IDs ≠ Chain IDs — use Domain IDs for Gas API and contracts
* BNB Chain USDC/USDT use **18 decimals** (exception to standard 6 decimals)
* Solana uses base58 addresses, not hex
* Move modules (Aptos/Sui) use module paths with `::` notation

### Getting Started

* See [Quickstart](/developers/quickstart) for integration examples
* See [Smart Contracts](/developers/smart-contracts) for detailed contract interfaces
* See [Backend APIs](/developers/backend-apis) for Gas API usage
