base-reth-node

base-reth-node runs the Base L2 execution client. It extends the standard Reth OP node with five extensions covering Flashblocks streaming, transaction pool RPC, resource metering, and proofs history retention.

Package

• Crate name: base-reth-node
• Source: bin/node
• Dockerfile: etc/docker/Dockerfile.client

Extensions

The node binary installs five extensions on top of the standard Reth OP node:

Extension	Crate	Purpose
TxPoolRpcExtension	base-txpool-rpc	Exposes custom transaction pool RPC methods
TxPoolExtension	base-txpool-tracing	Adds transaction pool tracing and diagnostics
MeteringExtension	base-metering	Resource metering RPC for gas accounting
FlashblocksExtension	base-flashblocks	Flashblocks streaming provider over WebSocket
ProofsHistoryExtension	base-proofs-history	Retains trie proofs for the fault proof window

These extensions are registered via Reth’s NodeComponents system. Each one hooks into the node lifecycle to provide additional RPC methods or background services.

Key Dependencies
