+**The feature is a work in progress**. A preview version is deployed to the [Westend Asset Hub](https://wiki.polkadot.network/docs/maintain-networks#westend-asset-hub)
+to gather feedback during development. This documentation will also be moved to the official Polkadot Wiki once the feature is stable.

 Our solution is Ethereum-compatible: You can write your contracts in Solidity and interact with the node
 using Ethereum JSON RPC alongside an Ethereum wallet like MetaMask. Under the hood, we recompile the
 contracts from YUL (EVM assembly) to RISC-V to run them using [PolkaVM](https://wiki.polkadot.network/docs/learn-jam-chain#polkadot-virtual-machine-pvm) instead of EVM.
 
 To keep things simple for now, you need to use our [REMIX](https://remix.polkadot.io) web frontend to compile
-your contracts to RISC-V and deploy them to Westend. Eventually, we will provide tools to accomplish this process locally.

 To develop an app that interacts with your contract, you can use any Ethereum JavaScript library of your choice. We
 are using [`ethers.js`](https://ethers.org) in our tests, which is the most popular library as of this writing.
