Token Bound Accounts

Token Bound Accounts, under the proposed "Non-fungible Token Bound Accounts" standard, let NFTs own Ethereum wallets, so a token can control a wallet that holds other assets. The article says the approach works with any NFT, including those minted before the standard, and that it removes the need for snapshots because each NFT stays permanently linked to a wallet address. It also describes airdropping soulbound NFTs into a token bound account as a way to upgrade existing NFT collections, and says a single NFT on one chain can control wallets on multiple chains, which is useful in ecosystems like the OP Stack.
