Sway is a Rust-inspired domain-specific programming language for writing smart contracts on the Fuel blockchain and Fuel VM, accompanied by Forc, a Cargo-like build and project management toolchain. The repository contains the compiler, standard library, language server, formatter, and related developer tooling.
Use cases
- write smart contracts for the fuel blockchain
- compile sway contracts to fuel vm bytecode
- build and deploy a counter contract with forc
- develop dapps on fuel with a rust-like language
- get lsp code completion and formatting for sway
- create src-20 native asset tokens on fuel
- migrate from solidity to a modern contract language
When to choose
- you are building smart contracts or predicates targeting the Fuel VM
- you want Rust-like ergonomics, generics, algebraic types, and unified tooling for contract development
- you need an integrated toolchain with LSP, formatter, testing, and deployment in one place
When to avoid
- you are deploying to EVM-compatible chains where Solidity or Vyper is required
- you need a general-purpose language for non-blockchain software
- your team and tooling ecosystem are already committed to Solidity standards
