Arbitrum Announces Rust SDK v0.10.0 - Major Boost for Rust & Stylus Developers
@Arbitrum has officially released
#Stylus Rust SDK v0.10.0, a significant upgrade to its Rust tooling that makes developing, deploying, and automating smart contracts in Rust easier and more efficient. This release is part of the latest Builder’s Block newsletter from the Arbitrum Foundation and marks an important milestone for builders working with Rust and WebAssembly (WASM) on Arbitrum.
What’s New in Rust SDK v0.10.0
The highlight of this release is the introduction of stylus-tools, a new library that upgrades the Stylus Rust SDK from a command-line–only workflow into a programmatic toolset:
✅ Programmatic Deployment & Management:
With stylus-tools, developers can execute actions such as deployment, activation, and verification directly from Rust code instead of relying only on CLI commands, enabling more automated workflows.
✅ Automation & Integration:
By exposing these capabilities as a Rust library rather than a CLI tool, teams can integrate contract management into CI/CD pipelines, automated tests, and build scripts.
✅ Multi-Contract & Testing Support:
The update simplifies workflows involving multiple contracts or more complex test environments, improving development and deployment across larger projects.
Overall, this release improves the developer experience for Rust builders on Arbitrum by increasing control and flexibility when working with Rust-based smart contracts.
Stylus and Rust on Arbitrum: What It Means
The Stylus Rust SDK lets developers write smart contracts in Rust that compile to WebAssembly (WASM) and execute on Arbitrum chains alongside Solidity contracts. Rust contracts retain full EVM interoperability while benefiting from Rust’s performance and safety features.
Before this release, Rust workflows relied mainly on cargo-stylus, a CLI tool for compiling and activating contracts. With the new stylus-tools library built into the SDK, these steps can now be handled directly in Rust-based automation, enabling cleaner and more maintainable development pipelines with less manual work.
Why This Upgrade Matters
This isn’t just a version increment, it’s a tooling milestone for Arbitrum’s multi-language ecosystem:
🔹 Improved Productivity: Developers can embed contract operations directly into code and scripts, reducing repetitive manual steps and the risks that come with them.
🔹 Professional Workflows: CI/CD integration, automated testing, and scripted deployments are now more attainable for Rust projects, aligning Arbitrum development with established software engineering practices.
🔹 Language Flexibility: Rust is now a more compelling alternative to Solidity for contract authors. With strong tooling support, Rust developers can confidently build real applications on Arbitrum.
In simple terms, this update turns Rust smart contract development from experimental tooling into a more production-ready experience a shift that benefits teams building complex applications or aiming for long-lived deployments on Arbitrum.
What’s Next
Alongside the Rust SDK release, the Builder’s Block #009 update also highlights other ecosystem tooling improvements, such as future integration of Hardhat support for Stylus and broader learning resources further indicating Arbitrum’s commitment to making development more accessible and powerful.
My take
The Rust SDK v0.10.0 release with stylus-tools marks a meaningful expansion of the Arbitrum developer experience. It enables builders to automate contract deployment and management directly from Rust and strengthens Rust as a first-class language for on-chain development on
@Arbitrum.
More broadly, this update signals Arbitrum’s continued focus on production-ready tooling, making it easier for teams to build complex applications using familiar, high-performance languages.
