Silius is a modular and highly efficient ERC-4337 bundler implementation in Rust. The project fully aligns with the broader ERC vision and ecosystem - staying up-to-date with spec changes and supporting up-and-coming features such as P2P protocol and alternative mempools. The bundler is structured in a way its core building blocks - main components and libraries - can be reused as Lego bricks in other AA projects in the ecosystem. Silius also contributes to the Rust Ethereum Ecosystem by building on and extending other Rust libraries and projects.
