Problem Statement

DeFi is fragmented, we want to build a platform that let users operate all the actions in one place, so they don't have to be familiar with each of the user interfaces from those DeFi protocols. With batched transactions, users can save gas and reduce waiting time. Using session keys, users can send transactions periodically. Those features really redefine the DeFi!!

Solution

First, we integrate with each DeFi protocol by calling their contract methods directly into a component. And user can choose to use multi-component in the order they want. Behind the scene, we send multiple user operations which are introduced in ERC-4337 into one transaction. The transaction will passthrough the entrypoint contract and route to the user's smart contract wallet and execute those user operations.
