Unlocking High-Performance Rust Smart Contract Development: OpenZeppelin x Arbitrum Stylus

Unlocking High-Performance Rust Smart Contract Development: OpenZeppelin x Arbitrum Stylus

This Open House session, hosted by Arbitrum's evangelist Swagtimus and presented by OpenZeppelin engineer Daniel Bigos, introduces developers to building secure, high-performance Rust smart contracts using Arbitrum Stylus. The session covers the motivation behind Stylus, benefits of writing contracts in Rust, the new OpenZeppelin Stylus library, and a live walkthrough of setting up, compiling, and deploying a Rust-based smart contract. It’s a must-watch for developers looking to move beyond Solidity and explore the next evolution of secure and scalable contract development.
