# Building on Goshen

Goshen is an Ethereum-equivalent Optimistic rollup. Developing on Goshen will not require any additional knowledge besides your Ethereum dev skills and favourite tools!

To deploy your Dapp on Goshen, you can use any Ethereum contract development framework like [Hardhat](https://hardhat.org/), [Foundry](https://github.com/foundry-rs/foundry), [Truffle](https://trufflesuite.com/), [Brownie](https://eth-brownie.readthedocs.io/en/stable/). Just change the RPC endpoint settings to Goshen network.
