-On the BNB Testnet, call the `MyProxyONFT721` contract to set the `MyONFT721` contract as a trusted remote contract. This will allow the `MyProxyONFT721` contract to send NFTs to the `MyONFT721` contract.

+Now that we have an NFT listed on the marketplace, we need to deploy the `CrossChainAgent` contract to the BNB Testnet and the ShimmerEVM Testnet.

+### Configure CrossChainAgent
 
-On the ShimmerEVM Testnet, call the `MyONFT721` contract to set the minimum gas required to receive an NFT from the BNB Testnet. This is necessary to ensure that the receiver has enough gas to complete the transfer.
+After deploying the `CrossChainAgent` contracts, you need to configure the `CrossChainAgent` contract on the BNB Testnet to send messages to the `CrossChainAgent` contract on the ShimmerEVM Testnet. This is the same process as setting the trusted remote address for the `ONFT721` contracts.

-Finally, call the `MyProxyONFT721` contract on the BNB Testnet to send an NFT to the `MyONFT721` contract on the ShimmerEVM Testnet. This script approves the `MyProxyONFT721` contract to transfer the NFT and then sends the NFT to the `MyONFT721` contract.

 ## Conclusion
-In the second part of this tutorial, you manually bridged an NFT from the BNB Testnet to the ShimmerEVM Testnet and listed it on the NFT marketplace. The final part of the series will explore how to create a cross-chain swap contract that allows users to trade NFTs across chains.
+In the third part of the tutorial, we have automated the buy flow of the cross chain NFT marketplace. We have deployed the necessary contracts on the BNB Testnet and the ShimmerEVM Testnet, and configured them to send and receive NFTs across chains.
