 Programs often require updates to add new functionality or fix errors, making the ability to update a program’s business logic essential. Updating a program involves modifying the on-chain program in a way that avoids mandatory updates to other components or dependencies, such as the frontend, backend, external links, and more.
 
-**Proxy programs** are a well-known design pattern in blockchain development that address upgrade challenges. This approach enables the delegation of function calls to a separate logic program. The pattern separates business logic from the program’s state and address, allowing upgrades or modifications to the logic without affecting the existing state or deployed address.

 1. Forwarding state-modifying messages while preserving the original sender's address.
 2. Handling state queries to retrieve data from the logic program.

 Making a program compatible with a proxy requires implementing specific features that enable the proxy to forward messages effectively while preserving the original sender's address. The following outlines the key adjustments and features incorporated into the [`Counter` program](https://github.com/gear-foundation/dapps/tree/master/contracts/proxy-example/counter) to support a proxy.
