Job 21476 contains a script that fetches AAVE/USD price from Binance, converts it to a 256-bit integer (wei-like precision), and submits an Ethereum transaction via Acurast to a contract at `<#CONTRACT_ADDRESS#>`. The transaction encodes the price as raw bytes and calls `fulfill(bytes)`. Gas limits and fees are hardcoded. This suggests Acurast is being used as a decentralized oracle feeder for DeFi contracts, specifically for AAVE price updates. The contract address is redacted in the source.

- C·192fd02aab · This script attempts to fetch the AAVEBUSD price from the Binance API, convert it to an 8-byte hex string, and encode it into a transaction payload. It is configured to submit this payload via an Ethereum transaction to a placeholder contract address using publicnode.com, specifying gas limits and fee parameters. The code includes callbacks to log success or failure hashes/errors. Placeholders exist for the contract address and standard library references. No execution proof is provided.
