This project provides a permissionless, extensible framework for cross-chain execution, supporting multiple runtimes (EVM, SVM, Move) and protocols (CCTP, NTT, VAA). It enables integrators to request execution of cross-chain messages through a decentralized system where relay providers generate signed quotes and execute transactions on destination chains. The framework minimizes overhead by keeping on-chain contracts stateless and stateless while handling verification and payment processing off-chain, making it suitable for developers building cross-chain applications who need a cost-effective alternative to traditional relayer systems.
