Avalanche Rosetta is an open-source server implementation for the Avalanche C-Chain, designed to provide standardized interfaces for interacting with blockchain networks via Rosetta API specifications. The server requires access to Avalanche services through RPC and can leverage the hosted API by Ava Labs or a locally-run Avalanche node. Installation involves cloning the repository and building the server with standard ‘make’ commands, resulting in a ‘rosetta-server’ binary. Detailed configuration, including RPC base URLs, network settings, and operational modes, is necessary before starting the service. Comprehensive RPC endpoints support blockchain operations like transaction processing and balance inquiries. Development tools facilitate build and test processes, including Docker support for multiple architectures and testnet environments. The project adheres to the BSD 3-Clause license, ensuring broad adoption and contribution potential in the web3 ecosystem.
