Libraries

Explore the key libraries for interacting with smart contracts on Polkadot-based networks. These libraries simplify contract calls, event listening, and transaction handling.

This section provides setup instructions, usage examples, and a comparison to help you select the right tool for your project.

Library Comparison

Consider the following features when choosing a library for your project:

Library	Language Support	Type Safety	Performance	Best For
Ethers.js	JavaScript, TypeScript	Limited	Efficient, widely optimized	General dApp development
Web3.js	JavaScript, TypeScript	Limited	Older codebase, can be less performant	Legacy projects, Web3.js users
viem	TypeScript only	Strong TypeScript support	Lightweight, optimized for bundling	TypeScript-heavy projects, modular workflows
Wagmi	TypeScript, React	Strong TypeScript support	React hooks-based, efficient caching	React applications, hook-based development
Web3.py	Python	Python typing support	Standard Python performance	Python-based blockchain applications

Warning

Web3.js has been sunset. You can find guides on using Ethers.js and viem in the Libraries section.

In This Section

Ethers.js

Learn how to interact with the Asset Hub chain using Ethers.js, from compiling and deploying Solidity contracts to interacting with deployed smart contracts.

Web3.js

Learn how to interact with the Asset Hub chain using Web3.js, deploying Solidity contracts, and interacting with deployed smart contracts.

Web3.py

Learn how to interact with the Asset Hub chain using the Web3 python library, deploying Solidity contracts, and interacting with deployed smart contracts.

viem

viem is a TypeScript library for interacting with EVM-compatible chains. This guide covers using viem to deploy and interact with smart contracts on Asset Hub.

Wagmi

Learn how to use Wagmi React Hooks to fetch and interact with smart contracts on Asset Hub for seamless dApp integration.
