Prefer Light Token for other purposes. Used by Light Token under the hood for rent-free storage of inactive Light Tokens. Supported by Phantom and Backpack. | Do not use for general-purpose token features. Use Light Token instead. | | Compressed PDA | User state and app state, nullifiers (payments and ZK applications), DePIN nodes, and stake accounts.

It provides code patterns, documentation references, and development guidance only. - **No credentials consumed.** The skill requires no API keys, private keys, or signing secrets. `env: []` is declared explicitly. - **User-provided configuration.** RPC endpoints, wallet keypairs, and authentication tokens (Privy, wallet adapters) are configured in the user's own application code — the skill only demonstrates how to use them. - **Install source.** `npx skills add Lightprotocol/skills` installs from the public GitHub repository ([Lightprotocol/skills](https://github.com/Lightprotocol/skills)). Verify the source before running. - **Audited protocol.** Light Protocol smart contracts are independently audited. Reports are published at [github.com/Lightprotocol/light-protocol/tree/main/audits](https://github.com/Lightprotocol/light-protocol/tree/main/audits). ## 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 available [skills](#defi) below * Locate relevant [documentation and examples](#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**: spawn subagent with `Read`, `Glob`, `Grep`, DeepWiki MCP access and load `skills/ask-mcp` ## Skills | Use case | Skill | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | | Build rent-free Solana programs with Light SDK (Anchor or Pinocchio).

Use them by name (`/light-sdk`, `/token-distribution`, `/testing`, etc.) or let Claude invoke them based on task context. ### Install to Cursor 1. Open Settings (**Cmd+Shift+J** / **Ctrl+Shift+J**) 2. Navigate to **Rules & Commands** → **Project Rules** → **Add Rule** → **Remote Rule (GitHub)** 3. Enter: `https://github.com/Lightprotocol/skills.git` Skills are auto-discovered based on context. Ask about light-token, defi, payments, or program migration and the agent uses the relevant skill automatically. ### Install to Any Agent ``` npx skills add Lightprotocol/skills ``` ## Context ### light-token A token standard functionally equivalent to SPL that stores mint and token accounts more efficiently. **Mint accounts** represent a unique mint and optionally store token-metadata. Functionally equivalent to SPL mints. **Token accounts** hold balances from any light, SPL, or Token-2022 mint, without paying rent-exemption. The token program pays rent-exemption cost for you. When an account has no remaining sponsored rent, the account is automatically compressed. Your tokens are cryptographically preserved as a compressed token account (rent-free). The account is loaded into hot account state in-flight when someone interacts with it again. Use for: Launchpads, DeFi, token transfers, payments, ... . ### light-PDA The Light-SDK pays rent-exemption for your PDAs, token accounts, and mints (98% cost savings). Your program logic stays the same. After extended inactivity (multiple epochs without writes), accounts auto-compress to cold state. Your program only interacts with hot accounts. Clients load cold accounts back on-chain via `create_load_instructions`. | Area | Change | | --------------- | --------------------------------------------------------------- | | State struct | Derive `LightAccount`, add `compression_info: CompressionInfo` | | Accounts struct | Derive `LightAccounts`, add `#[light_account]` on init accounts | | Program module | Add `#[light_program]` above `#[program]` | | Instructions | No changes | Use for: DeFi program state, AMM pools, vaults. ### Compressed token (Only use for Token Distribution) Compressed token accounts store token balance, owner, and other information of tokens like SPL and light-tokens. Compressed token accounts are rent-free. Any light-token or SPL token can be compressed/decompressed at will. Supported by Phantom and Backpack. Only Use for: airdrops, token distribution without paying upfront rent per recipient. ### Compressed PDA Compressed PDAs are derived using a specific program address and seed, like regular PDAs. Custom programs invoke the Light System program to create and update accounts, instead of the System program. Persistent unique identification. Program ownership. CPI between compressed and regular PDAs. Use rent-free PDAs for: user state, app state, nullifiers for payments, DePIN node accounts, stake accounts, nullifiers for zk applications. Not for shared state, pool, and config accounts. ### Guidelines * **light-token ≠ compressed token.** light-token is a Solana account in hot state. Compressed token is a compressed account, always compressed, rent-free. * **light-PDA ≠ compressed PDA.** light-PDA is a Solana PDA that transitions to compressed state when inactive. Compressed PDA is always compressed, derived like a PDA and requires a validity proof. * **light-token accounts hold SPL and Token-2022 balances**, not just light-mint balances. * When sponsored rent on a light-token or light-PDA runs out, the account compresses. It decompresses on next interaction. ### Documentation and Examples #### TypeScript Client (`@lightprotocol/compressed-token`) | Operation | Docs guide | GitHub example | | --------------------- |
