Intro

This documentation teaches you everything you need to know about smart contracts on Polkadot Asset Hub. The feature is a work in progress. A preview version is deployed to the Westend Asset Hub to gather feedback during development.

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 instead of EVM.

To keep things simple for now, you need to use our REMIX 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 in our tests, which is the most popular library as of this writing.
