Client Libraries & Wallet Kits

Lightweight, type-safe, tree-shakeable TypeScript interface for Ethereum; now the most downloaded EVM client.

Compact, battle-tested JavaScript library for Ethereum wallets, providers and contracts; huge installed base.

React (and Vue) hooks built on viem for wallet connection, contract reads/writes and caching in dApps.

Python library for interacting with EVM chains (originally EF, now stewarded by ApeWorX); standard for Python backends.

Modular, tree-shakeable successor to @solana/web3.js from Anza, with React hooks and typed RPC.

Classic 1.x Solana JavaScript SDK still in many apps; in maintenance mode in favor of Solana Kit.

High-performance Rust toolkit for EVM RPC, ABI and signing; replaced ethers-rs and powers Reth and Foundry.

Polished React wallet-connection modal built on wagmi, with theming and support for most EVM wallets.

Wallet connection, social login and onramp SDK from Reown (formerly WalletConnect) for EVM, Solana and Bitcoin.

Full-stack SDK for wallets, account abstraction, payments and contract deployment across EVM chains.

Original Ethereum JavaScript library; sunset by ChainSafe in 2025 and archived, migrate to viem or ethers.
