The following diagram provides a visual representation of how messages can be passed between different EVM blockchain layers, allowing for seamless message transfers and coordination between various components of a Super network.
+Message passing between a rootchain and an Edge-powered chain is achieved through continuous state synchronization, known as StateSync. This process involves transferring state data between system calls.
+Check out the StateSync document to learn more.
+When passing messages from an Edge-chain to a rootchain, the validator set commits checkpoints, which are snapshots of the Edge state containing only the root of the Exit events, excluding all transactions. Checkpoints serve as reference points for clients, and validators periodically checkpoint all transactions occurring on the Edge-powered chain to the rootchain. Checkpoints also ensure liveliness and are submitted to the associated rootchain asset contract.

+The bridge can exist in one of three states:
+The bridge is compatible with various token standards, including ERC-20, ERC-721, and ERC-1155, enabling a wide range of assets to be transferred between chains.
