Circle's DevRel team released CCTP support on Stellar, enabling developers to move USDC cross-chain natively. The integration tutorial covers Circle-specific details: domain ID 27 for Stellar, address handling differences from EVM chains, and managing the 7-decimal-to-6-decimal precision conversion for CCTP messages.
Circle announced CCTP (Cross-Chain Transfer Protocol) support on Stellar, enabling native USDC cross-chain transfers. The technical tutorial from Circle's DevRel team covers integration essentials for developers building on Stellar: assign domain ID 27 when calling CCTP contracts, use the CCTP forwarder contract for user accounts since Stellar addresses (stringy format) differ from EVM chains (raw 32-byte payloads), ensure USDC trustlines before receiving funds, and manage the precision conversion (CCTP uses 6 decimals, Stellar uses 7, with remainder staying on the sender's account). The guide includes supported domains table, contract addresses, technical overview, and quick start examples for moving USDC between Stellar and other chains.
