The Flare RPC documentation provides developers with a comprehensive guide for programmatically interacting with the Flare blockchain. With API endpoints designed to facilitate key operations such as sending transactions, querying blockchain data, and managing smart contracts, the documentation is built to support decentralized applications that require scalability and interoperability. Flare uses the Federated Byzantine Agreement (FBA) consensus mechanism to ensure secure, efficient operations across multiple blockchain ecosystems.
