# Migrating Your Project to Nova

The execution layer of zkLink Nova is built on top of [ZK Stack](https://docs.zksync.io/zk-stack), which leverages the underlying technology of zkSync. Building on zkLink Nova shares the same process of building on zkSync. 

zkSync provides developers with a smooth experience, offering tools for testing locally and compatibility with existing frameworks like Hardhat and Foundry. You can find the user guide for using these tools here.

[Hardhat with zkSync](https://docs.zksync.io/build/tooling/hardhat/getting-started.html)

[Foundry with zkSync](https://docs.zksync.io/build/tooling/foundry/overview.html)

For deploying smart contracts or using unique zkSync features, please use  `zksync-ethers` SDKs. zkSync provides SDKs for different programming languages. Please refer to the user guides in below.
