What is Arbitrum Stylus

Arbitrum Stylus represents a groundbreaking advancement within the Arbitrum technology stack, strategically crafted to enhance the landscape of smart contract development. It streamlines the creation of EVM-compatible smart contracts by supporting popular programming languages such as Rust, C, and C++, which are compiled down to WebAssembly (WASM). This innovation, known as EVM+, introduces a second, coequal virtual machine alongside the existing EVM. This advancement holds the promise of substantially reducing gas fees and accelerating transaction speeds, thereby unlocking new potential use cases on the blockchain.

In addition to providing a platform for developers to work with their favorite languages, Stylus maintains interoperability with Solidity, enabling smooth interactions between Solidity and Rust programs. This promotes a more diverse and inclusive developer community.



In conclusion, Arbitrum Stylus provides a better environment for developing smart contracts and can be easily integrated with MetaMask. Installing the Stylus testnet on your MetaMask is simple if you follow the instructions and consult the official documentation from Arbitrum. This new component of the Arbitrum tech stack promises increased efficiency and inclusivity in the blockchain space going forward, as well as opening doors for a larger developer community.
