Offchain Labs, the development company behind Arbitrum, announced it will launch Stylus later this year, which is a programming environment allowing developers to deploy programs written in traditional programming languages, such as Rust, C, and C++.

Offchain Labs said that DApps written in Stylus will be over an order of magnitude faster than their Solidity counterparts, and Stylus is EVM equivalent.
