Default account state

Configure the DefaultAccountState extension to set the initial state for newly created token accounts using Light Token.

Every new token account created under a mint starts in a specified state, such as frozen, requiring the freeze authority to thaw accounts before holders can transact.

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

Key Parameters

DefaultAccountState is configured with two parameters:

Parameter	Description
state	The initial AccountState for new token accounts. Set to Frozen to require approval before transacting.
freezeAuthority	Authority that can thaw frozen accounts and update the default state. Required when the default state is Frozen.

When a new token account is created for this mint, the token program automatically sets its state to the configured default. If the default is Frozen, the account cannot send or receive tokens until the freeze authority thaws it.

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

createMintInterface creates a basic Token 2022 mint with an interface PDA. To include the DefaultAccountState 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 DefaultAccountState, 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 DefaultAccountState and register with Light Token

Context:
- Guide: https://zkcompression.com/light-token/extensions/default-account-state
- 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: createInitializeDefaultAccountStateInstruction() + createMint()
Light Token: createInitializeDefaultAccountStateInstruction() + LightTokenProgram.createSplInterface()

### 1. Index project
- Grep `@solana/spl-token|Connection|Keypair|DefaultAccountState|TOKEN_2022` across src/
- Glob `**/*.ts` for project structure
- Identify: RPC setup, existing mint logic, entry point for T22 mint with default account state
- 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 default account state, 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
- Ensure a freeze authority is set (required when default state is Frozen)
- 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.DefaultAccountState]) → SystemProgram.createAccount → createInitializeDefaultAccountStateInstruction(AccountState.Frozen) → 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 freeze authority is set in initialization code
- 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
