## What it is
Revm is a highly efficient and stable Rust implementation of the Ethereum Virtual Machine (EVM). It serves both as a transaction executor for mainnet blocks and as an extensible framework for EVM variants like Optimism, and is widely used across Ethereum clients, tooling, L2s, and zkVMs.

## Use cases
- execute ethereum transactions locally in rust
- simulate evm smart contract calls
- trace evm transaction execution
- build a custom evm variant for an L2 rollup
- embed an evm interpreter in a blockchain client
- run evm inside a zkvm for provable execution
- test smart contracts with foundry-style cheatcodes

## When to choose
- you need a fast, robust EVM implementation in Rust
- you are building an Ethereum client, block builder, or dev tooling
- you need to extend the EVM with custom opcodes or L2 logic
- you want execution tracing and inspection support

## When to avoid
- you need a full Ethereum node rather than just the execution layer
- your stack is not Rust and you don't want FFI bindings
- you need a JavaScript/TypeScript EVM for browser tooling

## Facets
- artifact type: library
- maturity: stable
- function: interpreter, sdk, developer-tools, simulation
- domain: blockchain, developer-tools
- platform: rust, cross-platform
- tags: ethereum, evm, smart-contracts, transaction-execution, zkvm, layer2, no-std, cryptocurrency
