-# CCTP Sample App
+# [DEPRECATED] CCTP Sample App
+
+**This project is no longer actively maintained or supported by [Circle].**
+
+This repository is kept for historical and archival purposes only. No further updates, bug fixes, or new features will be implemented by the original maintainers.
+
+**Reason for Deprecation:** The sample code shared in the repository is outdated. Our focus has shifted to providing the latest and greatest of the CCTP experience through our [developer documentation portal](https://developers.circle.com/cctp/).
+
+**Recommended Alternative:** If you are looking for similar functionality, please consider using the [CCTP QuickStart](https://developers.circle.com/cctp/transfer-usdc-on-testnet-from-ethereum-to-avalanche).
+
+# Summary
 
 A sample app used to demonstrate CCTP step by step capabilities on testnet. The app currently supports Ethereum Sepolia, Avalanche Fuji C-Chain, and Arbitrum Sepolia testnets.
