JSON-RPC Namespaces

Reth supports all standard Ethereum JSON-RPC API methods. The API methods are grouped into namespaces, which are listed below:

admin: Administrative APIs for the node. DO NOT expose these APIs to the public internet.
eth: Ethereum APIs for interacting with the Ethereum blockchain.
tracing: APIs for tracing the execution of transactions, compatible with the popular Parity Tracing module.
debug: APIs for debugging the node, originally created by Geth.

One can easily interact with these APIs just like they would with any Ethereum client. You can use curl, a programming language with a low-level library, or a tool like Foundry to interact with the chain at the exposed HTTP or WS port. As a reminder, you need to run the command below to enable all of these apis:

RUST_LOG=info reth node --http --http.api "eth,admin,debug,tracing"

The IPC transport is also supported with --ipc!

This allows you to then call:

cast block-number
cast rpc admin_nodeInfo
cast rpc debug_traceTransaction
cast rpc trace_replayBlockTransactions
