What problem does it solve? Solana development spans rapidly evolving SDKs, program frameworks, and testing tools, making it hard to choose the right stack and avoid security pitfalls. This Skill provides an opinionated, up-to-date playbook that guides every layer of Solana development from wallet UI to on-chain programs. ## Core Features & Use Cases - Opinionated stack selection: Defaults to @solana/client + @solana/react-hooks for UI, @solana/kit for client code, and isolates legacy web3.js behind @solana/web3-compat adapters. - Program development guidance: Covers Anchor (macros, constraints, CPIs, Token-2022 interfaces) and Pinocchio (zero-copy, CU optimization, manual validation) with security checklists. - Testing and codegen workflows: LiteSVM/Mollusk unit tests, Surfpool integration tests, and Codama-based IDL client generation. - Use Case: When asked to build a Next.js dApp with wallet connection and an Anchor program, the Skill scaffolds the provider setup, generates typed clients via Codama, writes the program with proper account validation, and adds LiteSVM tests. ## Quick Start Ask the assistant to build a Solana token transfer dApp with wallet connection using the solana-dev skill.
