How to Query ERC-20 Token Balances and Transactions Using Ethers.js and Etherscan API
You can customize the Etherscan API request to suit your needs. Here are a few options:
- Start and End Block: Adjust the
startblockandendblockparameters to limit the range of blocks you want to query. - Sort: Set the
sortparameter toasc(ascending) ordesc(descending) to control the order of the transactions. - Token Transfers for All Tokens: You can modify the API call to query all token transfers for an address, not just a specific token contract, by omitting the
contractaddressparameter.
