+- **Project structure**: Organizes contracts, tests, scripts, and configuration into a consistent workspace. Provides a clear folder layout and a single configuration file (`hardhat.config.js`) to manage compilers, networks, and tooling.
+- **Compilation**: Compiles Solidity sources, supports multiple compiler versions, and generates ABI and bytecode artifacts.
+- **Local testing**: Runs tests written in JavaScript or TypeScript against an integrated local network, enabling fast feedback when validating contract behavior.
+- **Task automation**: Automates deployments, maintenance operations, and recurring workflows through custom scripts and Hardhat tasks.
+- **Contract interaction**: Enables reading contract state, sending transactions, and calling contract functions.

-    PolkaVM smart contracts with Ethereum compatibility are in **early-stage development and may be unstable or incomplete**.
 ## Introduction
 
 A local development node provides an isolated blockchain environment where you can deploy, test, and debug smart contracts without incurring network fees or waiting for block confirmations. This guide demonstrates how to set up a local Polkadot SDK-based node with smart contract capabilities.

 Next, you need to compile the two essential components for your development environment. The Substrate node provides the core blockchain runtime with smart contract support, while the ETH-RPC adapter enables Ethereum JSON-RPC compatibility for existing tooling:
