-Once the child and root contract is deployed on the Polygon and Ethereum chain respectively, these contracts have to be mapped using the PoS bridge. This mapping ensures that a connection is maintained between these two contracts across the chains. For doing this mapping,the Polygon team can be reached on [Discord](https://discord.com/invite/0xPolygon).

 One important thing to note is that in the root contract, there is a `onlyPredicate` modifier. It is recommended to use this modifier always because it ensures that only the predicate contract makes the state change on the root contract. The predicate contract is a special contract that triggers the root contract only when the transaction that happened on the Polygon PoS chain is verified by the `RootChainManager` on Ethereum chain. This ensures secure change of state on the root contract.
