The changes introduce a compliance mechanism that checks Ethereum addresses against the Office of Foreign Assets Control (OFAC) sanctions list. A new JSON file containing sanctioned addresses is added, along with an OfacChecker class responsible for loading and verifying these addresses. Modifications are made to the codebase to incorporate checks for blacklisted addresses during authorization and broadcasting processes, enhancing regulatory compliance.
