## What it is
Rust EVM (formerly SputnikVM) is a pure Rust implementation of the Ethereum Virtual Machine interpreter. It is a flexible, standalone library that can be embedded into other applications, run as a binary, or compiled to WebAssembly via no_std support.

## Use cases
- embed an Ethereum Virtual Machine into a Rust application
- run EVM smart contracts in a custom blockchain or sidechain
- build an Ethereum-compatible execution layer for another chain like Polkadot
- execute EVM bytecode in WebAssembly or no_std environments
- add custom opcodes or precompiled contracts to the EVM
- test Ethereum smart contracts against the official test suite
- simulate contract execution with a custom gas metering scheme

## When to choose
- you need a customizable EVM interpreter written in Rust
- you are building an Ethereum-compatible layer for a non-Ethereum chain
- you need no_std or WASM support for EVM execution
- you want to embed EVM execution directly in your application rather than running a full node

## When to avoid
- you need a full Ethereum node or JSON-RPC client rather than just the VM
- you prefer a battle-tested EVM implementation like geth's EVM with broader ecosystem support
- your project is not in Rust or lacks a Rust/C FFI path
