WHY ARBITRUM STYLUS IS A BIG DEAL

Summary from the TLDR Crypto newsletter

Arbitrum Stylus is reducing the barrier of entry for developers by allowing EVM-compatible smart contracts programmed in C, C++, and Rust. Stylus improves execution by 10x and scales memory by 50-100x. Since Solana programs are written in Rust, Stylus applications can be interoperable with the Solana ecosystem. It's expected to go live on mainnet in the coming months.
