# TAC Proxies

> TAC Proxy contracts receive cross-chain calls and assets from TON users and route them to EVM dApps and vice versa

## Proxy Solutions

When choosing a proxy solution, you currently have two options:

* **Custom**: Build and deploy a proxy for your EVM dApp using Solidity.
  Test locally using `TacLocalTestSdk` library or by using our joint [TON + TAC Testnet](/sdk/overview#testnet).
  This option supports any level of complexity.

* **Agnostic**: Implement calls to your EVM dApp directly in your frontend or JS-based backend using our SDK.
  No deployment needed.
  Test on our joint [TON + TAC Testnet](/sdk/overview#testnet).
  Has limitations, preferred for relatively simple use cases.
