ZK Chain Addresses
Deployment addresses of ZK Chain Bridgehub, SharedBridge, and STMs.
To enable seamless interoperability of the ZK Chain ecosystem, the Bridgehub, SharedBridges and State Transition Managers (STMs) are deployed on L1 and L2 to manage communication between ZK Chain contracts.
Learn more about Shared Bridges in the ZK Stack section. To understand the concept of ZK Chains, learn more on ZK Chains.
Getting the State Transition Manager for a ZK Chain
The Bridgehub smart contract has a read method stateTransitionManager that expects a chain ID as an argument.
The return value is the address of the StateTransition (a.k.a ZK Chain) contract address.
