ev-reth Overview

ev-reth is a modified reth Ethereum execution client optimized for Evolve rollups.

What is ev-reth?

ev-reth extends reth with:

• Engine API integration — Driven by ev-node for block production
• Rollup-specific features — Base fee redirect, deploy allowlist, custom precompiles
• Application gas sponsorship — Custom transaction type for sponsored batch operations
• Configurable chain parameters — Contract size limits, custom gas settings

ev-node drives ev-reth through the Engine API:

1. ev-node calls engine_forkchoiceUpdated with payload attributes
2. ev-reth builds a block from pending transactions
3. ev-node calls engine_getPayload to retrieve the block
4. ev-node broadcasts and submits to DA
5. ev-node calls engine_newPayload to finalize

Features

Feature	Description
Base Fee Redirect	Send base fees to treasury instead of burning
Deploy Allowlist	Restrict who can deploy contracts
Contract Size Limits	Increase max contract size beyond 24KB
Mint Precompile	Native token minting for bridges
Sponsored Batch Transactions	Sponsor user gas and execute multiple calls atomically

When to Use ev-reth

Use ev-reth when you want:

• Full EVM compatibility
• Ethereum tooling (Foundry, Hardhat, etc.)
• Standard wallet support (MetaMask, etc.)
• High-performance Rust execution
