Exploring the landscape of digital assets on the blockchain.
Transfer
event is emitted by the ERC20, ERC721, and ERC1155 standards when a token is transferred from one address to another. By tracking these events, we can create a history of the ownership and transfer of these assets.
To keep track of the balances, we also look at the balanceOf
function, which returns the balance of a particular address for a given token and store that data in our database.
