Pausable mint

Configure the Pausable extension to pause and resume all minting, burning, and transfers for a Token-2022 mint using Light Token.

When paused, all minting, burning, and transfers are blocked until the authority resumes the mint.

Set the compression_only flag when creating token accounts for this mint. Use transferInterface for transfers as usual.

Key Parameters

Pausable is configured with two parameters:

Parameter	Description
authority	The public key authorized to pause and resume the mint.
paused	Boolean flag indicating the current pause state. Initialized as false.

When paused, the Token-2022 program rejects all transfers, mints, and burns for the token. The pause authority can resume operations at any time.

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

createMintInterface creates a basic Token 2022 mint with an interface PDA. To include the Pausable extension, use the instruction approach shown in the other tab.

Create Interface PDA for Existing Mint

If you already have a Token-2022 mint with Pausable, create an interface PDA with Light Token.

import { LightTokenProgram } from "@lightprotocol/compressed-token";
import { TOKEN_2022_PROGRAM_ID } from "@solana/spl-token";

const createSplInterfaceIx = await LightTokenProgram.createSplInterface({
    feePayer: payer.publicKey,
    mint: mintKeypair.publicKey,
    tokenProgramId: TOKEN_2022_PROGRAM_ID,
});

## Create a Token-2022 mint with Pausable and register with Light Token

Context:
- Guide: https://zkcompression.com/light-token/extensions/pausable-mint
- Skills and resources index: https://zkcompression.com/skill.md
- SPL to Light reference: https://zkcompression.com/api-reference/solana-to-light-comparison
- Packages: @lightprotocol/compressed-token, @lightprotocol/stateless.js, @solana/spl-token
- Restriction: compression_only accounts required

SPL equivalent: createInitializePausableInstruction() + createMint()
Light Token: createInitializePausableInstruction() + LightTokenProgram.createSplInterface()

### 1. Index project
- Grep `@solana/spl-token|Connection|Keypair|Pausable|TOKEN_2022` across src/
- Glob `**/*.ts` for project structure
- Identify: RPC setup, existing mint logic, entry point for T22 mint with pausable
- Task subagent (Grep/Read/WebFetch) if project has multiple packages to scan in parallel

### 2. Read references
- WebFetch the guide above — follow the Instruction tab for the full flow
- 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 T22 mint with pausable, register existing T22 mint, migrate existing SPL code)
- AskUserQuestion: does the project already use Token-2022?
- 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
- Note: when paused, all minting, burning, and transfers are rejected until resumed
- 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 @solana/spl-token`
- Create T22 mint: getMintLen([ExtensionType.PausableConfig]) → SystemProgram.createAccount → createInitializePausableConfigInstruction(pauseAuthority) → createInitializeMint2Instruction
- Register with Light Token: LightTokenProgram.createSplInterface({ mint, tokenProgramId: TOKEN_2022_PROGRAM_ID })
- Transfer: createTransferInterfaceInstructions() from @lightprotocol/compressed-token/unified
- 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
- Confirm pause authority is set correctly
- 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
