Tron JSON-RPC API

JSON-RPC API reference for TRON blockchain. Explore method list, request examples, and how to connect to GetBlock's TRON RPC endpoints

TRON exposes an Ethereum-compatible JSON-RPC subset over the /jsonrpc path, so EVM-oriented tooling can read TRON data and TVM contract state. Every request is an HTTP POST with a JSON-RPC 2.0 body: a method, params, and an id. Responses carry the same id and a result or error.

Addresses in this API use TRON's hex (0x41...) form, and balances are in SUN. For transaction creation, staking, and TRON-native features, use the REST API; TRON's idiomatic SDK, TronWeb, is built on REST rather than this JSON-RPC layer.
