• C·65ceb7c8b9 · This script configures an asynchronous HTTP GET request to Binance's public API to fetch the AAVEBUSD ticker price. Upon receiving the response, it parses the JSON, converts the price to a 18-decimal fixed-point integer, and formats it into a 64-character hexadecimal string prefixed with '0x'. This byte payload is then encoded using a configured Ethereum ABI encoder. The script attempts to submit this payload to a smart contract at a placeholder address via a configured Ethereum node, specifying a method signature of 'fulfill(bytes)' and fixed gas parameters. It includes callbacks to log success or failure hashes/errors to the console.
