fuellabs/fuels-rs

fuels-rs is the official Rust SDK for the Fuel Network, a high-performance blockchain designed for smart contract execution. It gives Rust developers everything they need to build, deploy, and interact with smart contracts on Fuel without manually constructing raw transactions or dealing with low-level protocol details. The SDK handles the full workflow: you can compile Sway smart contracts (Fuel's native programming language) directly from Rust build scripts, deploy them to a running Fuel node or to a local test network spun up by the SDK itself, and call contract functions through type-safe Rust bindings that are auto-generated from the contract's ABI. This tight compile-time integration means many contract interaction errors are caught before the code even runs. The SDK also provides wallet abstractions, account management, transaction building, and querying the chain for balances, receipts, and events. You would use fuels-rs when you are a Rust developer building applications on the Fuel Network. Common scenarios include writing integration tests for Sway smart contracts, building back-end services that submit transactions or read chain state, and automating deployments as part of a CI/CD pipeline. The local network capability is particularly useful for testing because it lets you run a complete Fuel environment in your test suite without a live node. The project is written entirely in Rust and maintained by Fuel Labs, the core team behind the Fuel Network. It is the primary SDK for Rust-based Fuel development, complemented by a separate TypeScript SDK for frontend and JavaScript environments.
