⛽ Today we’re proud to release the first public version of Yul+, new low-level language for Ethereum!

Yul+ makes writing stateless contracts (including optimistic rollups) easier and increases code legibility.

🔪 Why is this needed? Solidity doesn’t support pass-by-reference or slices.

This means parsing Merkle branches/proofs---a key component of stateless contracts---is wastefully expensive if written in Solidity.

➕ Yul+ adds a number of QoL improvements, such as enums, constants, Booleans, and by-default safemath. But most importantly, it adds in-memory structures.

This means structured calldata can be parsed *in-place* (no memory copies, no problems!).

🔗 If you’re building a stateless contract, including an optimistic rollup, then you’ll find that Yul+ will remove a whole lot of headache.

🛠️ If you want to support our R&D efforts to make optimistic rollups a reality and scale Ethereum to thousands of decentralized tps, we’re participating in the @gitcoin Grants CLR Round 5.

With #QuadraticFunding, every dollar counts!
