How to TBAs work

Token Bound Accounts rely on the ERC6551 Standard which connects an NFTs token ID with a registry that deploys the smart wallet. This registry allows the owner to process transactions via the TBA linked to the NFT.

https://tokenbound.org/ the creators of ERC6551 allow any NFT to be a 6551 via their public registry on networks where deployed.

In this format the process is;

1. You start with an ERC-721 NFT.

2. You register a Token-Bound Account for it.

3. That account becomes active and programmable.
