CANTILEVER
A bridge which uses EIP-4337 and Account Abstraction infrastructure
Project Description
This is a bridge, technologically based on currently existing EIP-4337 infrastructure. It uses AA for pools, validators, bundler, entrypoint and aggregator for validating and sending gasless transactions reliable way. We implemented three chains (Polygon, Gnosis, Celo), used Biconomy SDK/API and Safe AA. Presentation: https://docs.google.com/presentation/d/1Rvk3BQ2hx5XhSgoSkBVFoeC86hyKvuj96OtTEva9xbw
How it's Made
Backend is written in typescript, run on debian server with nginx and pm2. We use Biconomy SDK for sending user operations to the Entrypoint. The crosschain frontend is in vue. Some peripheral contracts like Safe EIP-4337 module and mocks for testing were tested and deployed with Foundry (solidity).
