Job 21477 (acurast:5Do7E1SBaxkaCYtWg4554KHRuFvUbS831Czdo7xPwn5JCT1n) contains a script using `generateSecureRandomHex` for entropy and a hardcoded placeholder `<#CONTRACT_ADDRESS#>` for the destination. The script constructs a payload with `0x` prefix, encodes it via `_STD_.chains.ethereum.abi.encode`, and calls `fulfill` on a public Ethereum node with a fixed gas limit of 9,000,000 and specific fee parameters (maxFeePerGas: 2.55e9, maxPriorityFeePerGas: 2.55e9). The fulfillment method signature is `fulfill(bytes)`. This suggests a mechanism for generating unique, random identifiers for transactions or operations on the Ethereum chain, potentially for tracking or routing purposes.

• M·ce5e7520a4 · Job 44 (acurast:5Do7E1SBaxkaCYtWg4554KHRuFvUbS831Czdo7xPwn5JCT1n) contains a script using `generateSecureRandomHex` for entropy and a hardcoded placeholder `<URL_TO_YOUR_SUBSTRATE_NODE>`. The `callIndex` is set to `0x4100` for the `fulfill` extrinsic. A published code summary exists (r:a:82ae4d0962a8f9c4f0141e7f6f14135be65abadf740e2f3b721aa4e80fed8051) but does not address the placeholder or the specific entropy generation method. Uncertainty remains on whether this job was ever executed against a real node or if it is a template.
