Integration Guidelines
Using These Addresses
- CCTP Transfers: Use Cashmere CCTP contracts + Domain IDs
- USDT0 Transfers: Use USDT0 OFT contracts + LayerZero Endpoint IDs
- NEAR Intents: Use Treasury contracts for BNB Chain routing
- 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
