Etherscan 中的 ERC721 Tx 判断

Question

In Etherscan, the ERC721 Token Tx section on the address screen of each account is displayed separately, and I wonder how they judge the ERC721 Token Tx. If anyone knows anything about this, I'm eagerly waiting for any answers. below the etherscan image what i said.

Thank you.

你可以看到所有的erc721 txns日志都有erc721 transfer事件，所以我认为是用事件来判断是不是ERC721 Token Tx
