Solana Kit Development Guide

A comprehensive guide for building Solana applications with @solana/kit - the modern, tree-shakeable, zero-dependency JavaScript SDK from Anza.

Overview

Solana Kit (formerly web3.js 2.0) is a complete rewrite of the Solana JavaScript SDK with:

• Tree-shakeable: Only ship code you use (-78% bundle size)
• Zero dependencies: No third-party packages
• Functional design: Composable, no classes
• 10x faster crypto: Native Ed25519 support
• TypeScript-first: Full type safety
