Arbitrum Stylus equips your rollup to support more powerful apps and expands its developer talent pool by millions. How? By bringing WebAssembly (WASM) onchain. Stylus makes it possible for developers to write smart contracts in popular languages like Rust, C, and C++, in addition to Solidity. Besides supporting more widely known programming languages, WASM also brings performance improvements that can give your chain faster transaction times, lower gas fees, and more sophisticated applications. 

That makes Stylus a game changer for your rollup. And best of all, Conduit makes it easy to implement. We’ll tell you how below, plus everything else builders need to know about Stylus. 

What is Arbitrum Stylus and how does it work?

Stylus equips your rollup with a WASM-based virtual machine (WASM VM) that runs alongside the traditional Ethereum Virtual Machine (EVM). Arbitrum dubs this paradigm MultiVM. MultiVM allows developers to write smart contracts in both Solidity and WASM-compatible languages like Rust, C, and C++. 

Interoperability between Solidity and WASM is key to MultiVM. With Stylus, a single application can leverage smart contracts written in both Solidity and WASM languages, and each contract can call functions written in the other languages. That allows developers to get the best of both worlds, and leverage the many libraries available in all supported languages. This will enable new onchain functionalities that haven’t previously been explored. 

Stylus also makes it possible for your rollup to support larger, more complex applications onchain, running at higher speeds and with lower fees. This is due to WASM’s superior memory optimization — smart contracts built with WASM languages can consume memory more efficiently onchain and execute faster. Those performance improvements, combined with the interoperability we described above, open a world of new possibilities for onchain builders.

Why Stylus is a game changer for rollups

Arbitrum Orbit rollups that implement Stylus gain several key advantages over other chains. First, Stylus offers performance improvements that benefit both developers and users. The combination of WASM’s memory optimizations and the ability to use high-performance languages like Rust allows for faster transaction execution, lower gas fees, and more complex applications. Rollups that implement Stylus can run more compute-intensive apps, such as cryptographic verifications, zero-knowledge proofs, complex generative art algorithms, and more advanced gaming experiences.

Stylus allows rollups to tap into a wider developer talent pool. By supporting popular programming languages like Rust and C++, rollups can attract more web2 developers and onboard new projects more easily. This broad developer support can lead to faster ecosystem growth and new innovations.

With these enhancements, rollups can offer a more attractive user experience by reducing costs and increasing app speed, all while enabling more sophisticated applications that were previously infeasible onchain.

How Conduit supports Stylus for rollup developers

Conduit has been a supporter of Stylus since its early testnet stages, and now that Stylus is live on mainnet, we’re proud to offer Stylus support as the default for all new Arbitrum Orbit rollups launched on our platform. The screenshot below shows how easy it is – just click, and your Arbitrum Orbit rollup with Stylus is deployed in minutes. 

Additionally, Conduit already powers the highest-performing Arbitrum Orbit rollups in operation, thanks in large part to our new G2 Sequencer. One example is Proof of Play, whose gaming rollup has surpassed 65 Mgas/s. That level of computational power combined with Stylus’ performance enhancements can make your rollup unstoppable. 

We’re confident that Stylus will play a central role in the future of high-performance rollups, and Conduit is leading the charge to help developers implement this powerful technology on their chains.
