As part of its projects to help Ethereum users exchange tokens on the more scalable Ethereum layer-2 network StarkNet, Nethermind has "transpiled and compiled" decentralized exchange (DEX) Uniswap v3 on "Warp". 

With Nethermind's new Warp project, Ethereum-native projects can now be "transpiled" to StarkNet.? 

In an Oct. 9 Medium post, team lead Jorik Schellekens announced the team's achievement of this milestone. 

Based on Nethermind's definition, Warp is a Solidity-to-Cairo Transpiler that enables Solidity-based Ethereum projects to move their codebase to StarkNet and therefore benefits from lower fees compared to other services. 

Warp allows converting Solidity code into Cairo, a versatile application programming language. In other words, transpiring is essentially converting one programming language into another with a similar level of abstraction. 

Nethermind plans to run Uniswap's entire test suite on StarkNet soon, even though the Warp plugin is still technically in development. Warp was able to successfully transpile and deploy every Solidity file from Uniswap v3 as a result of StarkNet's new "contract creation from other contracts" capability. 

Schellekens pointed out that Uniswap's codebase is so large that projects of any size will be able to use StarkNet, “With Warp rapidly maturing, the barrier to entry for large and small projects alike to test out the capabilities of StarkNet is lowering.” 

Although Warp has translated Solidity into Cairo, it has not done so perfectly. Nethermind developers have yet to include some Solidity functions to Cairo, according to Warp's GitHub, while several other necessary functions need to be added by developers or will not be supported at all.
