Approve grants a delegate permission to transfer up to a specified amount of tokens from your account.
- Each token account can have only one delegate at a time.
- Any new approval overwrites the previous one.
Revoke removes all delegate permissions from a Light Token account.
Only the token account owner can approve or revoke delegates.

Localnet
Devnet

# start local test-validator in a separate terminal
light test-validator

In the code examples, use createRpc() without arguments for localnet.

Get an API key from Helius and add to .env:

.env

API_KEY=<your-helius-api-key>

In the code examples, use createRpc(RPC_URL) with the devnet URL.

import "dotenv/config";
import { Keypair } from "@solana/web3.js";
import { createRpc } from "@lightprotocol/stateless.js";
import {
    createMintInterface,
    mintToCompressed,
    approve,
} from "@lightprotocol/compressed-token";
import { homedir } from "os";
import { readFileSync } from "fs";

// devnet:
// const RPC_URL = `https://devnet.helius-rpc.com?api-key=${process.env.API_KEY!}`;
// const rpc = createRpc(RPC_URL);
// localnet:
const rpc = createRpc();

const payer = Keypair.fromSecretKey(
    new Uint8Array(
        JSON.parse(readFileSync(`${homedir()}/.config/solana/id.json`, "utf8")),
    ),
);

(async function () {
    const { mint } = await createMintInterface(rpc, payer, payer, null, 9);
    await mintToCompressed(rpc, payer, mint, payer, [{ recipient: payer.publicKey, amount: 1000n }]);

    const delegate = Keypair.generate();
    const tx = await approve(
        rpc,
        payer,
        mint,
        500,
        payer,
        delegate.publicKey,
    );

    console.log("Tx:", tx);
})();

Revoke a delegate

import "dotenv/config";

## Approve and revoke token delegates

Context:
- Guide: https://zkcompression.com/light-token/cookbook/approve-revoke
- Skills and resources index: https://zkcompression.com/skill.md
- Packages: @lightprotocol/compressed-token, @lightprotocol/stateless.js

SPL equivalent: approve() / revoke() → Light Token: approve() / revoke()

### 1. Index project
- Grep `@solana/spl-token|Connection|Keypair|approve|revoke|delegate` across src/
- Glob `**/*.ts` for project structure
- Identify: RPC setup, existing delegation logic, entry point for delegation
- 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 delegate 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
- TaskList to check remaining work

## Add approve and revoke CPI to an Anchor program

Context:
- Guide: https://zkcompression.com/light-token/cookbook/approve-revoke
- Skills and resources index: https://zkcompression.com/skill.md
- Crate: light-token (ApproveCpi, RevokeCpi)
- Example: https://github.com/Lightprotocol/examples-light-token/tree/main/programs/anchor/basic-instructions/approve

Key CPI structs: `light_token::instruction::ApproveCpi`, `light_token::instruction::RevokeCpi`

### 1. Index project
- Grep `declare_id|#\[program\]|anchor_lang|Account<|Pubkey|invoke|approve|revoke|delegate` across src/
- Glob `**/*.rs` and `**/Cargo.toml` for project structure
- Identify: program ID, existing instructions, account structs, delegate accounts
- 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 both Approve and Revoke CPI 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: what is the goal? (add approve/revoke to existing program, new program from scratch, migrate from SPL approve/revoke)
- AskUserQuestion: should the owner be an external signer or a PDA? (determines invoke vs invoke_signed)
- AskUserQuestion: do you need both approve and revoke, or just one?
- 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 ApproveCpi/RevokeCpi structs → call .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
