Light Token Client SDKs

Client-side cookbook for @lightprotocol/compressed-token (TypeScript) and light_token_client (Rust). Covers all token operations: create mints, associated token accounts, transfer, approve, revoke, burn, wrap, unwrap, freeze, thaw, close, and load.

Creation cost	SPL	Light Token
Token account	~2,000,000 lamports	~11,000 lamports

Prerequisites

Examples show both localnet and devnet configurations. For devnet, set:

• API_KEY env var — Helius or Triton RPC API key. In production, load from a secrets manager.
• ~/.config/solana/id.json — local Solana keypair (solana-keygen new). In production, load from a secrets manager.

Workflow

1. Clarify intent
   • Recommend plan mode, if it's not activated
   • Use AskUserQuestion to resolve blind spots
   • All questions must be resolved before execution
2. Identify references and skills
   • Match task to domain references below
   • Locate relevant documentation and examples
3. Write plan file (YAML task format)
   • Use AskUserQuestion for anything unclear — never guess or assume
   • Identify blockers: permissions, dependencies, unknowns
   • Plan must be complete before execution begins
4. Execute
   • Use Task tool with subagents for parallel research
   • Subagents load skills via Skill tool
   • Track progress with TodoWrite
5. When stuck: ask to spawn a read-only subagent with Read, Glob, Grep, and DeepWiki MCP access, loading skills/ask-mcp. Scope reads to skill references, example repos, and docs.

Security

This skill does not pull, store, or transmit external secrets. It provides code patterns, documentation references, and development guidance only.

• Declared dependencies. Devnet and mainnet examples require API_KEY (Helius or Triton RPC key) and read ~/.config/solana/id.json for the payer keypair. Neither is needed on localnet. In production, load both from a secrets manager.
• User-provided configuration. RPC endpoints, wallet keypairs, and authentication tokens are configured in the user's application code. The skill demonstrates patterns — it does not store or transmit secrets.
• Install source. npx skills add Lightprotocol/skills installs from the public GitHub repository (Lightprotocol/skills). Verify the source before running.
• Subagent scope. When stuck, the skill asks to spawn a read-only subagent with Read, Glob, and Grep scoped to skill references, example repos, and docs.
• Audited protocol. Light Protocol smart contracts are independently audited. Reports are published at github.com/Lightprotocol/light-protocol/tree/main/audits.
