# 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 ## Quick Start ### Installation ```bash npm install @solana/kit ``` For specific program interactions: ```bash npm install @solana-program/system @solana-program/token ``` ### Minimal Example ```typescript import { createSolanaRpc, createSolanaRpcSubscriptions, generateKeyPairSigner, lamports, pipe, createTransactionMessage, setTransactionMessageFeePayer, setTransactionMessageLifetimeUsingBlockhash, appendTransactionMessageInstruction, signTransactionMessageWithSigners, sendAndConfirmTransactionFactory, getSignatureFromTransaction, } from "@solana/kit"; import { getTransferSolInstruction } from "@solana-program/system"; const LAMPORTS_PER_SOL = BigInt(1_000_000_000); async function transferSol() { // 1. Connect to RPC const rpc = createSolanaRpc("https://api.devnet.solana.com"); const rpcSubscriptions = createSolanaRpcSubscriptions("wss://api.devnet.solana.com"); // 2. Create signers const sender = await genera...
