## What it is
Fe is a statically typed, Rust-like programming language for the Ethereum Virtual Machine (EVM) featuring explicit effects, message-passing contracts, traits, generics, and higher-kinded types. It ships with an integrated toolchain including a compiler CLI (fe), package manager, formatter, and language server.

## Use cases
- write smart contracts for ethereum
- alternative to solidity for evm development
- compile contracts to evm bytecode
- develop secure decentralized applications
- learn a rust-like smart contract language
- build erc20 tokens with typed message handlers

## When to choose
- you want compile-time safety guarantees like explicit effects and overflow protection when writing EVM contracts
- you prefer Rust-like syntax and modern language features (traits, generics, pattern matching) over Solidity
- you want an integrated toolchain with package manager, formatter, and language server

## When to avoid
- you need production-ready, battle-tested contracts - Fe 26.x is explicitly not production-ready with known bugs and sub-optimal bytecode
- your project depends on the mature Solidity ecosystem, audits, and tooling
- you need a large standard library or extensive third-party contract libraries
