 ## Introduction
 
+The `revive` compiler is used to compile Solidity smart contracts to [`PolkaVM`](/develop/smart-contracts/evm/native-evm-contracts/#polkavm){target=\_blank} bytecode, which allows it to be uploaded to Asset Hub. An Ethereum RPC faciliates interaction with existing Ethereum tools, such as Ethers.js or Metamask
+
 Ethers.js is a lightweight library that enables interaction with Ethereum Virtual Machine (EVM)-compatible blockchains through JavaScript. This article demonstrates how to use Ethers.js to interact and deploy smart contracts to the Asset Hub.
