An Incomplete Taxonomy of Cross-Chain Messages

An Incomplete Taxonomy of Cross-Chain Messages

Single or Batched

Single Messages - Single messages have a single target address, target chainId, and data payload. The vast majority of cross-chain messages today are single messages.

Example:

function dispatchMessage(uint256 toChainId, address to, bytes calldata data) external payable returns (bytes32 messageId);
pragma solidity ^0.8.0;
contract AtomicityGuard {
// address => block => status
uint256 private constant _ENTERED = 1;
mapping(address => mapping( uint256 => uint256)) ledger;
modifier nonAtomic() {
