Open-source ERC-4337 bundler written in Golang by Stackup.
The Stackup bundler is a modular, high-performance, and fully compliant ERC-4337 bundler built in Go by the engineering team at Stackup, most notably Stackup's co-founder, Hazim (@hazim-j). While developers can self-host the open-source bundler, Stackup also offers a hosted solution to make it easier and more scalable for smart contract wallet developers to get started.
