Let's now imagine that this contract is going to live on one chain, but we want the minting and the upgrading to be performed by a xref:governance.adoc[`governor`] contract on another chain.

In order to do that, we will start by adding xref:api:crosschain.adoc#CrossChainEnabled[`CrossChainEnabled`] to our contract. You will notice that the contract is now abstract. This is because `CrossChainEnabled` is an abstract contract: it is not tied to any particular chain and it deals with cross-chain interactions in an abstract way. This is what enables us to easily reuse the code for different chains. We will specialize it later by inheriting from a chain-specific implementation of the abstraction.
