## Integrate light-token APIs for stablecoin payments

Context:
- Guide: https://zkcompression.com/light-token/payments/overview
- 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
- Packages: @lightprotocol/compressed-token, @lightprotocol/stateless.js
- Import from @lightprotocol/compressed-token/unified for all interface APIs

SPL → Light Token API mapping:
| Operation    | SPL                               | Light Token                              |
| Receive      | getOrCreateAssociatedTokenAccount() | createLoadAtaInstructions() / loadAta()  |
| Transfer     | createTransferInstruction()        | createTransferInterfaceInstructions()    |
| Delegated Transfer | transfer() (delegate signs)  | transferInterface(..., ownerPubkey, delegateSigner, ...) |
| Get Balance  | getAccount()                      | getAtaInterface()                        |
| Tx History   | getSignaturesForAddress()         | getSignaturesForOwnerInterface()         |
| Wrap SPL     | N/A                               | createWrapInstruction() / wrap()         |
| Unwrap       | N/A                               | createUnwrapInstructions() / unwrap()    |

### 1. Index project
- Grep `@solana/spl-token|@lightprotocol|createTransferInstruction|getAccount|Connection|Keypair|stablecoin|payment` across src/
- Glob `**/*.ts` and `**/*.tsx` for project structure
- Identify: RPC setup, existing token operations, payment flow, wallet signing pattern
- 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 Instruction and Action tabs for each operation
- 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 payment integration, migrate existing SPL payment flow, add alongside existing SPL)
- AskUserQuestion: which operations? (receive, send, balance, history, wrap, unwrap — or all)
- AskUserQuestion: instruction-level API (build your own transactions) or action-level API (high-level, fewer lines)?
- 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 (createRpc with ZK Compression endpoint)
- Key pattern: import from `@lightprotocol/compressed-token/unified` for all interface APIs
- 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

How rent sponsorship works:
- A rent sponsor PDA pays the rent-exemption cost on account creation so creators never lock up SOL
- The fee payer bumps a small virtual rent balance (766 lamports) on each write to keep the account active (hot)
- Set your application as the fee payer so users never pay rent or top-ups

Key APIs:
| Language   | Function                                        | Payer parameter                           |
| TypeScript | createLightTokenTransferInstruction()            | 5th argument: `sponsor.publicKey`         |
| TypeScript | createAtaInterface()                             | 2nd argument: `sponsor` (Keypair)         |
| Rust       | TransferInterface { ..., payer: sponsor.pubkey() } | `payer` field                           |
| Rust       | CreateAssociatedTokenAccount::new(sponsor, ...)  | 1st argument: sponsor pubkey              |

### 1. Index project
- Grep `feePayer|payer|createTransferInstruction|createLightTokenTransferInstruction|@lightprotocol|@solana/spl-token|Connection` across src/
- Glob `**/*.ts` and `**/*.tsx` for project structure
- Identify: existing token operations, RPC config, fee payer setup, signing flow
- Check package.json for existing @lightprotocol/* dependencies
- Task subagent (Grep/Read/WebFetch) if project has multiple packages to scan in parallel

### 2. Read references
- WebFetch the guide above — review TypeScript and Rust 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: what is the goal? (add sponsored top-ups to existing light-token code, new integration from scratch, migrate from user-pays to sponsor-pays)
- AskUserQuestion: TypeScript or Rust client?
- AskUserQuestion: which operations need sponsoring? (transfers only, ATA creation + transfers, all write operations)
- 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
- Key pattern: set the `payer` parameter to the sponsor's public key on transfer and ATA creation instructions
- The sponsor Keypair must sign the transaction alongside the user
- 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` for the token APIs
- Set sponsor as payer: `createLightTokenTransferInstruction(senderAta, recipientAta, sender.publicKey, amount, sponsor.publicKey)`
- Sign with both sponsor and sender: `sendAndConfirmTransaction(rpc, tx, [sponsor, sender])`
- Follow the guide and the approved plan
- Write/Edit to create or modify files
- TaskUpdate to mark each step done

## Create rent-free nullifier PDAs to prevent duplicate actions

Context:
- Guide: https://zkcompression.com/pda/compressed-pdas/nullifier-pda
- Skills and resources index: https://zkcompression.com/skill.md
- Dedicated skill: https://github.com/Lightprotocol/skills/tree/main/skills/zk-nullifier
- Rust crates: light-nullifier-program, light-client
- TS packages: @lightprotocol/nullifier-program, @lightprotocol/stateless.js
- Example: https://github.com/Lightprotocol/examples-light-token/blob/main/rust-client/actions/create_nullifier.rs
- Program source: https://github.com/Lightprotocol/nullifier-program/

Key APIs:
- Rust: create_nullifier_ix(), fetch_proof(), build_instruction(), derive_nullifier_address()
- TS: createNullifierIx(), fetchProof(), buildInstruction(), deriveNullifierAddress()

### 1. Index project
- Grep `nullifier|create_nullifier|createNullifierIx|deriveNullifierAddress|NFLx5WGPrTHHvdRNsidcrNcLxRruMC92E4yv7zhZBoT` across src/
- Glob `**/*.rs` and `**/*.ts` for project structure
- Identify: existing transaction building, duplicate prevention logic, payment flow
- Check Cargo.toml or package.json for existing light-* dependencies
- Task subagent (Grep/Read/WebFetch) if project has multiple packages to scan in parallel

### 2. Read references
- WebFetch the guide above — review both Rust and TS code samples
- 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: Rust or TypeScript?
- AskUserQuestion: what is the goal? (prevent duplicate payments, idempotent instruction execution, other use case)
- AskUserQuestion: do you need the helper (create_nullifier_ix) or manual proof fetching (fetch_proof + build_instruction)?
- 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 pattern: create unique 32-byte ID → build nullifier instruction → prepend to transaction
- If checking existence is needed, add derive_nullifier_address + get_compressed_account check
- If anything is unclear or ambiguous, loop back to step 3 (AskUserQuestion)
- Present the plan to the user for approval before proceeding

### 5. Implement

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

transferInterface() transfers tokens in a single call. The recipient parameter is a wallet public key.
Pass the source token-account owner pubkey and the signing authority separately: owner-signed flows use (owner.publicKey, owner); delegated flows use (owner.publicKey, delegate). Do not use removed InterfaceOptions.owner.
The SDK derives and creates the destination ATA internally. All transfers use transferChecked under the hood.
- Light Token → Light Token: transfers between Light Token accounts
- SPL → Light Token: locks SPL tokens in interface PDA, mints to Light Token account
- Light Token → SPL: burns Light Token balance, releases SPL tokens from interface PDA

Edge case: for explicit destination token accounts (PDA/program-owned), use transferToAccountInterface()
or createTransferToAccountInterfaceInstructions(). Most integrations should use transferInterface().

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

### 1. Index project
- Grep `@solana/spl-token|@lightprotocol|createTransferInstruction|getAccount|wallet|signTransaction|signAllTransactions|Connection` across src/

- APIs return TransactionInstruction[][] — handle multi-tx case with signAllTransactions
- 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
