## Zone contracts

The protocol provides the factory and shared Zone runtimes below. Each zone has its own portal proxy pointing to the shared implementation. Confirm the deployed runtime and configuration before integrating; these addresses alone do not establish execution-proof enforcement. See the [current settlement verification limits](https://tempo.xyz/developers/docs/protocol/zones/proving).
