Live Demo: Link
Swimlanes Diagram: Link exemplifying start-to-finish web2 user journery from onboarding with their web2 accounts to becoming a web3 citizen without having to change their original address, thanks to Account Abstraction! The diagram shows using Lit Protocol as the MPC wallet provider instead of Web3Auth as we had to pivot mid-way through the hackthon due to Lit SDK import issues, the flow is the same.
An fully functional NFT marketplace for web2 (and web3) users.
Collectors can buy, sell and transfer NFTs without ever creating a crypto wallet or paying for gas. Any NFT or ETH is sent to an Account Abstraction contract ('s predicted address), whose owner is an MPC wallet (or Multisig owned by one or more wallets) created and controlled by any web2 authentication method, OAuth, OTP or WebAuthn.
