About
The problem it solves Participating in DeFi as a liquidity provider often takes up to 10 steps. Before Chainspan  After Chainspan  We make it super easy and safe with a self custodian vault (SCV) that is controlled by an AA wallet account.  The ONLY owner of the SCV is the AA account, and the AA account's guardian is a single EOA account. This way, we are able to ring fence all the actions needed to interact with a specific defi opportunity into one contract that is only accessible by a single EOA owner. Staking or yield farming as LP is now more secure with better privacy as users’ assets sit in SCV that is only accessible by the owner, to some extent the assets are isolated on top of an infrastructure that is privately owned without sharing.
How it's made
Challenges we ran into getting the smart contract wallet to do the automate swapping from any token into the desired tokens for the DeFi opportunity was a challenge, and UX remains a work in progress since it's not clear to first time users how to send the correct token from their EOA wallet into this smart contract wallet. Once that part is made clearer, it should be easy for users to use these AA wallets to interact with the entire Base ecosystem.
