  * @notice SpokePoolVerifier is a contract that verifies that the SpokePool exists on this chain before sending ETH to it.
+ * @dev This contract must be deployed via Create2 to the same address on all chains. That way, an errant transaction sent
+ * to the wrong chain will be blocked by this contract rather than hitting a dead address. This means that this contract
+ * will not work to protect chains, like zkSync, where Create2 address derivations don't match other chains.
