## Description

Use when user asks to "build a Solana dapp", "write an Anchor program", "create a token", "debug Solana errors", "set up wallet connection", "test my Solana program", "fuzz my Solana program", "deploy to devnet", "send a v1 transaction", "support larger transactions", "fix maxSupportedTransactionVersion", or "explain Solana concepts" (rent, accounts, PDAs, CPIs). Also for program architecture (state layout, compute units, throughput, naming), quick on-chain lookups via public RPC + curl, gasless or sponsored-fee transactions (Kora), server-side signing with KMS/Turnkey/Privy/Fireblocks (Solana Keychain), and issuing stablecoins or allowlisted tokens (Mosaic). Covers wallets, Anchor/Pinocchio, Codama clients, Surfpool/LiteSVM/Mollusk testing, security review, and v1 transactions (SIMD-0385). Prefers @solana/kit 8 plugin clients building transaction v1 by default, @solana/kit-plugin-wallet + @solana/react for wallets, web3.js v3 as the legacy migration target, and Surfpool for local networks.

# Solana Development Skill

## What this Skill is for
Use this Skill when the user asks for:
- Solana dApp UI work (React / Next.js)
- Wallet connection + signing flows
- Transaction building / sending / confirmation UX
- Transaction v1 / larger transactions (SIMD-0385), the default format for new code; sending, reading, indexing
- On-chain program development (Anchor or Pinocchio)
- Program architecture, state layout, PDA seed conventions, naming, parallelization, cranks, vault topology
- Client SDK generation (typed program clients)
- Local testing (Surfpool, LiteSVM, Mollusk) and fuzz testing (Trident, cargo-fuzz)
- Security hardening and audit-style reviews
- Confidential transfers (Token-2022 ZK extension)
- Gasless / sponsored-fee transactions (Kora), server-side signing with KMS / MPC / managed wallets (Solana Keychain), regulated token issuance (Mosaic)
- **Toolchain setup, version mismatches, GLIBC errors, dependency conflicts**
- **Upgrading Anchor/Solana CLI versions, migration between versions**
- **Migrating web3.js v1 code to web3.js v3 or Kit**
