How to create a Token Bound Account NFT – ERC6551 + ERC4337

In this video, we’ll go over how to create a token bound account with ERC6551 support. We will build an app where a user can claim an NFT with their personal wallet. That NFT will then have an ERC4337 wallet (smart wallet) created for it where it can claim an ERC20 and ERC1155 token. Those tokens will not be owned by your personal wallet, but owned by the NFTs wallet and the NFT.
