Stellar Developers Meeting features a live CCTP demo enabling canonical USDC to move cross-chain from Stellar to Ethereum, Base, Arc, and Solana. SDF developers showcase a wrapper contract that combines USDC approval and burn into a single atomic transaction. The integration handles Stellar's 7-decimal precision, Circle's attestation flow, and enables permissionless destination minting.
Stellar Developers Meeting covered CCTP (Circle's Cross-Chain Transfer Protocol), enabling canonical USDC movement between Stellar and other blockchains without wrapping or liquidity pools. SDF Senior Developer Advocate Elliot demonstrated the practical implementation: burn tokens on the source chain, wait for Circle's attestation, then mint on the destination chain. The key innovation was a wrapper contract that reduces the typical two-step (approve + deposit) flow into a single atomic call, streamlining the developer experience. The demo moved 5 USDC from Stellar testnet to Arc testnet, showing real-world mechanics including handling the seven-decimal-to-six-decimal precision conversion between Stellar and EVM chains. The session also introduced upcoming features and discussed permissionless minting options that allow any address to trigger the mint function on the destination chain, making the protocol more composable for DApps.
