+Block explorers such as Etherscan may interpret this payload as a call to a Solidity function with the ABI selector `0x00000000`. As of July 2023, Etherscan's database has the `0x00000000` selector mapped to a function called `fulfillBasicOrder_efficient_6GL6yc(tuple parameters)`.
+
+Since the `CREATE2` factory smart contract was written directly in EVM assembly and not Solidity, the factory has no conception of ABI. To have block explorers display a different function in their UI, you can set the first 4 bytes of the salt to some hardcoded value while using the last 28 bytes to mine the desired address.
