The Light Token Program

High-performance token standard that is functionally equivalent to SPL while reducing account creation cost by 200x and being more CU efficient on hot paths. The Light Token SDK keeps code changes minimal and is a superset of the SPL-token API.

Note: This page is for the new Light Token Program Beta.
For legacy compressed tokens, please go here.

Mint Accounts

Light-mint accounts represent a unique mint and optionally can store token-metadata. Functionally equivalent to SPL mints.

Creation Cost	Light-Token	SPL-Token
Mint Account	0.00001 SOL	0.0015 SOL

Token Accounts

Light-token accounts can hold balances from any light, SPL, or Token-2022 mint, without the need to pay rent-exemption.

- SPL to Light reference: https://zkcompression.com/api-reference/solana-to-light-comparison
- Packages: @lightprotocol/compressed-token, @lightprotocol/stateless.js

SPL equivalent: createMint() → Light Token: createMintInterface()

### 1. Index project
- Grep `@solana/spl-token|Connection|Keypair|createMint` across src/
- Glob `**/*.ts` for project structure
- Identify: RPC setup, existing mint logic, entry point for mint creation
- Task subagent (Grep/Read/WebFetch) if project has multiple packages to scan in parallel

### 2. Read references
- WebFetch the guide above — follow the TypeScript Client tab
- WebFetch skill.md — check for a dedicated skill and resources matching this task
- TaskCreate one todo per phase below to track progress

### 3. Clarify intention
- AskUserQuestion: what is the goal? (new feature, migrate existing SPL code, add alongside existing)
- AskUserQuestion: does the project already have mint operations to extend, or is this greenfield?
- Summarize findings and wait for user confirmation before implementing

### 4. Create plan
- Based on steps 1–3, draft an implementation plan: which files to modify, what code to add, dependency changes
- Verify existing connection/signer setup is compatible with the cookbook prerequisites
- If anything is unclear or ambiguous, loop back to step 3 (AskUserQuestion)
- Present the plan to the user for approval before proceeding

### 5. Implement
- Add deps if missing: Bash `npm install @lightprotocol/compressed-token @lightprotocol/stateless.js`
- Follow the cookbook guide and the approved plan
- Write/Edit to create or modify files
- TaskUpdate to mark each step done

### 6. Verify
- Bash `tsc --noEmit`
- Bash run existing test suite if present
- TaskUpdate to mark complete

### Tools
- mcp__zkcompression__SearchLightProtocol("<query>") for API details
- mcp__deepwiki__ask_question("Lightprotocol/light-protocol", "<q>") for architecture
- Task subagent with Grep/Read/WebFetch for parallel lookups

## Add create-token-account CPI to an Anchor program

Context:
- Guide: https://zkcompression.com/light-token/cookbook/create-token-account
- Skills and resources index: https://zkcompression.com/skill.md
- SPL to Light reference: https://zkcompression.com/api-reference/solana-to-light-comparison
- Crate: light-token (CreateTokenAccountCpi)
- Example: https://github.com/Lightprotocol/examples-light-token/tree/main/programs/anchor/basic-instructions/create-token-account

Key CPI struct: `light_token::instruction::CreateTokenAccountCpi`

### 1. Index project
- Grep `declare_id|#\[program\]|anchor_lang|Account<|Pubkey|invoke|token_account|vault|owner|mint` across src/
- Glob `**/*.rs` and `**/Cargo.toml` for project structure
- Identify: program ID, existing instructions, account structs, vault/token account patterns
- Read Cargo.toml — note existing dependencies and framework version
- Task subagent (Grep/Read/WebFetch) if project has multiple crates to scan in parallel

### 2. Read references
- WebFetch the guide above — review the CPI tab under Program: token account creation with .rent_free() chain
- WebFetch skill.md — check for a dedicated skill and resources matching this task
- TaskCreate one todo per phase below to track progress

### 3. Clarify intention
- AskUserQuestion: what is the goal? (add create-token-account to existing program, new program from scratch, migrate from SPL token account init)
- AskUserQuestion: should the payer be an external signer or a PDA? (determines invoke vs invoke_signed)
- Summarize findings and wait for user confirmation before implementing

### 4. Create plan
- Based on steps 1–3, draft an implementation plan: which files to modify, what code to add, dependency changes
- Follow the guide's step order: Build CreateTokenAccountCpi → .rent_free() → .invoke() or .invoke_signed()
- If anything is unclear or ambiguous, loop back to step 3 (AskUserQuestion)
- Present the plan to the user for approval before proceeding

### 5. Implement
- Add deps if missing: Bash `cargo add light-token anchor-lang@0.31`
- Follow the guide and the approved plan
- Write/Edit to create or modify files
- TaskUpdate to mark each step done

### 6. Verify
- Bash `anchor build`
- Bash `anchor test` if tests exist
- TaskUpdate to mark complete

### Tools
- mcp__zkcompression__SearchLightProtocol("<query>") for API details
- mcp__deepwiki__ask_question("Lightprotocol/light-protocol", "<q>") for architecture
- Task subagent with Grep/Read/WebFetch for parallel lookups
- TaskList to check remaining work

## Integrate light-token with Privy embedded wallets

Context:
- Guide: https://zkcompression.com/light-token/toolkits/for-privy
- Skills and resources index: https://zkcompression.com/skill.md
- SPL to Light reference: https://zkcompression.com/api-reference/solana-to-light-comparison
- Dedicated skill: https://github.com/Lightprotocol/skills/tree/main/skills/payments-and-wallets
- Packages: @lightprotocol/compressed-token, @lightprotocol/stateless.js
- Node.js example: https://github.com/Lightprotocol/examples-light-token/tree/main/privy/nodejs
- React example: https://github.com/Lightprotocol/examples-light-token/tree/main/privy/react

SPL → Light Token API mapping:
| Operation        | SPL                          | Light Token                              |
| Transfer         | createTransferInstruction()  | createTransferInterfaceInstructions()    |
| Receive          | getOrCreateAssociatedTokenAccount() | createLoadAtaInstructions()       |
| Wrap SPL→Light   | N/A                          | createWrapInstruction()                  |
| Unwrap Light→SPL | N/A                          | createUnwrapInstructions()               |
| Get balance      | getAccount()                 | getAtaInterface()                        |
| Tx history       | getSignaturesForAddress()    | getSignaturesForOwnerInterface()         |

### 1. Index project
- Grep `privy|@privy-io|usePrivy|PrivyProvider|createTransferInstruction|@solana/spl-token|Connection` across src/
- Glob `**/*.ts` and `**/*.tsx` for project structure
- Identify: Privy SDK version, existing wallet setup, RPC config, token operations
- Check package.json for existing @lightprotocol/* or @solana/spl-token dependencies
- Task subagent (Grep/Read/WebFetch) if project has multiple packages to scan in parallel

### 2. Read references
- WebFetch the guide above — review both Node.js and React code examples
- WebFetch skill.md — check for a dedicated skill and resources matching this task
- TaskCreate one todo per phase below to track progress

### 3. Clarify intention
- AskUserQuestion: Node.js or React?
- AskUserQuestion: what is the goal? (new Privy integration, migrate existing Privy+SPL code, add light-token alongside existing SPL)
- AskUserQuestion: which operations? (transfer, wrap, unwrap, balances, tx history — or all)
- Summarize findings and wait for user confirmation before implementing

### 4. Create plan
- Based on steps 1–3, draft an implementation plan: which files to modify, what code to add, dependency changes
- Verify existing Privy wallet setup is compatible (signTransaction or sendTransaction pattern)
- Key integration pattern: build unsigned tx with light-token SDK → sign with Privy → send to RPC
- If anything is unclear or ambiguous, loop back to step 3 (AskUserQuestion)
- Present the plan to the user for approval before proceeding

### 5. Implement
- Add deps if missing: Bash `npm install @lightprotocol/compressed-token @lightprotocol/stateless.js`
- Set up RPC: `createRpc(RPC_ENDPOINT)` with a ZK Compression endpoint (Helius, Triton)
- Import from `@lightprotocol/compressed-token/unified` for the interface APIs
- Follow the guide and the approved plan
- Write/Edit to create or modify files
- TaskUpdate to mark each step done

### 6. Verify
- Bash `tsc --noEmit`
- Bash run existing test suite if present
- TaskUpdate to mark complete

### Tools
- mcp__zkcompression__SearchLightProtocol("<query>") for API details
- mcp__deepwiki__ask_question("Lightprotocol/light-protocol", "<q>") for architecture
- Task subagent with Grep/Read/WebFetch for parallel lookups
- TaskList to check remaining work
