Project structure

The project is a standard Rust workspace with multiple crates - each responsible for specific functionalities. Each crate can also be imported into any other project, bootstrapping building account abstraction projects in Rust.

At the moment, the following crates are available:

• primitives - types, constants, and other basic primitives

• contracts - interface for entry point smart contract and debug tracing utilities

• uopool - implementation of user operation mempool, validation logic (canonical and alt mempools), reputation

• bundler - implementation of the bundling functionalities (bundle builder)

• rpc - implementation of JSON-RPC interfaces, HTTP and WS

• grpc - crate that implements logic for running components (uopool and bundler) as gRPC services
