Summit

The Summit contract is deployed on Synapse Chain and acts as the "rollup" of SIN for the attested states of all remote chains in the system. The snapshot root of the contract determines the source of truth for snapshots for all chains and is attested to by every actor in the system every time they perform an action.

The contract works hand in hand with the BondingManager to keep remote chains up-to-date on the state of the agents & forces all agents to attest to the validity of the agents in every snapshot and ultimately serves as a global state of the interchain network.
