+# Archival Notice
+
+This repository was a home for the reference implementation of the engine built to automatically execute profitable orders placed on the [deBridge Liquidity Network](https://docs.debridge.finance/dln-the-debridge-liquidity-network-protocol/introduction) (DLN) protocol. Since 2024, the DLN protocol has become a highly competitive market, with many solvers competing to be the first to take each new profitable order using highly efficient custom-built engines, while the current implementation remains conservative.
+
+So we decided to stop active development of this product and archive the repository. It would remain public and open to anyone who wants to have example of some basic implementation of solver, and build your own implementation that will be able to compete for speed with other solvers. We can't provide support for it.
