[Blockchain Express] Alchemy open-sources Rundler, an ERC-4337 packager infrastructure written in Rust! 🎉 Alchemy announced that it has open-sourced the high-performance, high-reliability, and modular Rundler to accelerate the transition to smart accounts. Rundler is used to support Alchemy's Bundler API endpoints, and the team is still continuing to develop new features such as integrated or distributed deployment, precise Gas estimation, etc. In the future, Rundler will build P2P memory pools, alternative memory pools, Entry Point V0.7 with multi-version support, signature aggregation, and block builder integration. What do you think of Rundler? Feel free to talk in the comments!
