MathWallet now supported ERC6551 (NFT owned wallet)
What is ERC6551 ?
ERC-6551 is Ethereum’s new standard for NFT, designed to make them more usable and interactive. The key feature of ERC-6551 is Token Bound Account (TBA), which provides NFT with an interface to smart contract accounts and a permissionless registry.
ERC-6551 gives every ERC-721 token the full functionality of an Ethereum account. Token-bound accounts allow ERC-721 tokens to own other on-chain assets and interact with utilities, without requiring changes to existing ERC-721 smart contracts or infrastructure. Tokens are account-bound and immutably record all activities performed on the blockchain.
