What problem does it solve? Developers building Solana applications struggle with outdated web3.js 1.x patterns, bloated bundles, and unclear transaction-building APIs. This Skill provides current, accurate guidance for @solana/kit, the modern tree-shakeable, zero-dependency SDK from Anza, covering everything from RPC connections to transaction signing and sending. ## Core Features & Use Cases - Transaction Building with Pipe: Compose versioned transactions functionally using pipe, fee payer setters, blockhash lifetimes, and instruction appending. - Signers and Account Fetching: Generate KeyPairSigners, sign or partially sign transactions, and fetch or decode on-chain accounts with codecs. - Advanced Patterns: Custom RPC transports with retry and failover, compute budget optimization, durable nonces, address lookup tables, and WebSocket subscriptions. - Use Case: You need to transfer SOL from a TypeScript backend. Use this Skill to create an RPC connection, build the transaction with a transfer instruction, sign it, and confirm it on devnet in a few lines of code. ## Quick Start Ask the agent to write a TypeScript script using @solana/kit that transfers 0.1 SOL between two generated wallets on devnet.
