Smart contract development & toolchains

Highlights

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust. It is a smart contract development toolchain that manages your dependencies, compiles your project, runs tests, deploys, and lets you interact with the chain from the command-line and via Solidity scripts.

Fe is a high-level language for the EVM. It is heavily inspired by Rust and implemented in it too. You can use Fe to write smart contracts for Ethereum or any EVM-equivalent platform. Currently, we are developing Fe v2, which introduces an improved type system. While it does not yet compile to EVM, users can still analyze their code using the CLI or an editor plugin.

Solady is an open-source repository containing highly-optimized Solidity snippets. It offers efficient implementations of commonly-used libraries, such as MerkleProofLib, alongside cutting-edge features like LibZip. By thoughtfully encapsulating low-level inline assembly within flexible APIs, Solady simplifies the process of writing clean and efficient Solidity code. More than just a library, Solady also serves as a learning resource and experimental laboratory for pioneering gas-optimization techniques. Solady is used in the codebases of Optimism and Coinbase. With respect to the OP stack, Solady contributes in the following ways: Provides a Solidity and JavaScript implementation of FastLZ compression algorithm, which is used for more accurate gas estimations in the Fjord upgrade. The JavaScript code is very minimal, allowing for it's easy translation into Go. Various other utilities such as bytecode proxies and string operations.
