OpenZeppelin Relayer API
The OpenZeppelin Relayer is an open-source transaction relay infrastructure service that enables decentralized applications to submit and manage blockchain transactions across EVM-compatible networks (Ethereum, Polygon, Arbitrum, Optimism), Solana, and Stellar. The self-hosted REST API provides endpoints for relayer management, transaction submission and signing, nonce management, gas estimation, and RPC calls. It supports gasless transactions, sponsored transactions, and configurable policies with rate limiting at 100 requests/second (burst 300).
