Quest Details


In the final quest of this campaign, we’ll be utilizing the skills picked up in the previous quest to create and deploy a cross-chain counter contract! This contract will be deployed on two different blockchains and it’ll allow an address on one chain to use that chain’s contract to communicate with the destination chain’s contract.

After you’ve completed this quest, you’ll be equipped with the skills and confidence to utilize the concepts you’ve learnt to extend cross-chain messaging functionality to other use cases.

Let’s dive in!
