End-to-end Solana development playbook (Jan 2026). Prefer Solana Foundation framework-kit (@solana/client + @solana/react-hooks) for React/Next.js UI. Prefer @solana/kit for all new client/RPC/transaction code. When legacy dependencies require web3.js, isolate it behind @solana/web3-compat (or @solana/web3.js as a true legacy fallback). Covers wallet-standard-first connection (incl. ConnectorKit), Anchor/Pinocchio programs, Codama-based client generation, LiteSVM/Mollusk/Surfpool testing, and security checklists.
- Initial release of the Solana Development Skill, providing an end-to-end playbook for Solana dApp, program, and client development. - Strongly recommends using Solana Foundation framework-kit (@solana/client + @solana/react-hooks) for React/Next.js UIs. - Prefers @solana/kit for all new client, RPC, and transaction code; web3.js is isolated behind compatibility adapters when needed. - Includes best practices for wallet-standard-first connections, Anchor/Pinocchio program development, Codama-based client SDKs, and modern testing tools (LiteSVM, Mollusk, Surfpool). - Details security checklists and provides clear operating procedures for Solana-focused project execution.
