JSON-RPC
A lightweight request-response protocol many blockchain nodes use for transaction broadcast and chain queries.
- Also known as
- rpcnode rpc
JSON-RPC defines a simple JSON request and response format for calling methods on a remote service. Blockchain nodes expose RPC methods so wallets, explorers, and backend systems can query data or submit signed transactions.
RPC endpoints can expose sensitive or resource-intensive capabilities, so production deployments should use authentication, network isolation, rate limiting, and least-privilege method access.
