## What it is
Dapptools is a suite of Unix-philosophy CLI tools for Ethereum smart contract development, including dapp (build/test/fuzz/deploy), seth (Ethereum CLI client), hevm (EVM debugger and symbolic execution engine), and ethsign (transaction signing). It also ships a set of audited Solidity contract libraries (ds-*).

## Use cases
- build and test solidity smart contracts from the command line
- fuzz and symbolically execute EVM bytecode
- debug ethereum transactions against local or mainnet state
- send transactions and query contracts from the terminal
- sign ethereum transactions with a keystore or hardware wallet
- deploy solidity contracts to ethereum networks

## When to choose
- you prefer composable Unix-style CLI tools for Ethereum development
- you need symbolic execution or formal verification of EVM code
- you want audited ds-* Solidity contract libraries
- you already use Nix for dependency management

## When to avoid
- you are a new user seeking active support - the project recommends Foundry instead
- you need Windows support
- you want a modern integrated toolchain with active community development
