Permissioned Burn

What Is Permissioned Burn?

The Token Extension Program's PermissionedBurnConfig mint extension requires a configured burn authority to co-sign every burn for the mint.

While the burn authority is set:

The standard Burn and BurnChecked instructions fail with TokenError::InvalidInstruction.
Burns must use PermissionedBurnInstruction::Burn or PermissionedBurnInstruction::BurnChecked, signed by both the burn authority and the token account's owner or delegate.

The burn authority is a co-signer, not a replacement for the owner. The authority alone cannot burn tokens from someone else's token account, and a token account owner cannot burn without the authority's signature. A permanent delegate must also use the permissioned burn instructions and still needs the burn authority's co-signature.

This lets an issuer keep token supply in sync with an off-chain record, for example a tokenized asset that must stay backed 1:1, by preventing holders from unilaterally burning tokens.

The burn authority can be rotated later with SetAuthority using AuthorityType::PermissionedBurn. Setting the authority to None disables permissioned burning and re-enables the standard burn instructions. The extension data itself stays on the mint.

A local test validator also bundles an older Token-2022 build, so to run the examples on this page, load the v11.0.0 program from devnet into your test validator:

Terminal

solana program dump -u devnet TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb token_2022.so
solana-test-validator --reset --bpf-program TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb token_2022.so

How to Create a Mint and Burn With Permission

To create a mint with permissioned burn and burn tokens:

Calculate the mint account size and rent needed for the mint and the PermissionedBurnConfig extension.
Create the mint account with CreateAccount, initialize PermissionedBurnConfig, and initialize the mint with InitializeMint.
Create a token account and mint tokens.
Burn with PermissionedBurnInstruction::BurnChecked signed by both the token account owner and the burn authority.
Optionally disable permissioned burning with SetAuthority using AuthorityType::PermissionedBurn and a None authority, which re-enables the standard burn instructions. The full code examples below show this step.

Calculate account size

Calculate the mint account size for the base mint plus the PermissionedBurnConfig extension. This is the size used in CreateAccount.

Example

const client = await createClient()
  .use(generatedPayer())
  .use(
    solanaRpc({
      rpcUrl: "http://localhost:8899",
      rpcSubscriptionsUrl: "ws://localhost:8900"
    })
  )
  .use(rpcAirdrop())
  .use(airdropPayer(lamports(1_000_000_000n)));

const mint = await generateKeyPairSigner();
const burnAuthority = await generateKeyPairSigner();

const permissionedBurnExtension = extension("PermissionedBurn", {
  authority: burnAuthority.address
});

const mintSpace = BigInt(getMintSize([permissionedBurnExtension]));

Calculate rent

Calculate rent using the size needed for the mint plus the PermissionedBurnConfig extension.

Example

const client = await createClient()
  .use(generatedPayer())
  .use(
    solanaRpc({
      rpcUrl: "http://localhost:8899",
      rpcSubscriptionsUrl: "ws://localhost:8900"
    })
  )
  .use(rpcAirdrop())
  .use(airdropPayer(lamports(1_000_000_000n)));

const mint = await generateKeyPairSigner();
const burnAuthority = await generateKeyPairSigner();

const permissionedBurnExtension = extension("PermissionedBurn", {
  authority: burnAuthority.address
});

const mintSpace = BigInt(getMintSize([permissionedBurnExtension]));

const mintRent = await client.rpc
  .getMinimumBalanceForRentExemption(mintSpace)
  .send();

Create the mint account

Create the mint account with the calculated space and lamports.

Example

const client = await createClient()
  .use(generatedPayer())
  .use(
    solanaRpc({
      rpcUrl: "http://localhost:8899",
      rpcSubscriptionsUrl: "ws://localhost:8900"
    })
  )
  .use(rpcAirdrop())
  .use(airdropPayer(lamports(1_000_000_000n)));

const mint = await generateKeyPairSigner();
const burnAuthority = await generateKeyPairSigner();

const permissionedBurnExtension = extension("PermissionedBurn", {
  authority: burnAuthority.address
});

const mintSpace = BigInt(getMintSize([permissionedBurnExtension]));

const mintRent = await client.rpc
  .getMinimumBalanceForRentExemption(mintSpace)
  .send();

await client.sendTransaction([
  getCreateAccountInstruction({
    payer: client.payer,
    newAccount: mint,
    lamports: mintRent,
    space: mintSpace,
    programAddress: TOKEN_2022_PROGRAM_ADDRESS
  })
]);

Initialize PermissionedBurn

Initialize the PermissionedBurnConfig extension on the mint with the burn authority.

Example

const client = await createClient()
  .use(generatedPayer())
  .use(
    solanaRpc({
      rpcUrl: "http://localhost:8899",
      rpcSubscriptionsUrl: "ws://localhost:8900"
    })
  )
  .use(rpcAirdrop())
  .use(airdropPayer(lamports(1_000_000_000n)));

const mint = await generateKeyPairSigner();
const burnAuthority = await generateKeyPairSigner();

const permissionedBurnExtension = extension("PermissionedBurn", {
  authority: burnAuthority.address
});

const mintSpace = BigInt(getMintSize([permissionedBurnExtension]));

const mintRent = await client.rpc
  .getMinimumBalanceForRentExemption(mintSpace)
  .send();

await client.sendTransaction([
  getCreateAccountInstruction({
    payer: client.payer,
    newAccount: mint,
    lamports: mintRent,
    space: mintSpace,
    programAddress: TOKEN_2022_PROGRAM_ADDRESS
  }),
  getInitializePermissionedBurnInstruction({
    mint: mint.address,
    authority: burnAuthority.address
  })
]);

Initialize the mint

Initialize the mint with InitializeMint in the same transaction.

Example

const client = await createClient()
  .use(generatedPayer())
  .use(
    solanaRpc({
      rpcUrl: "http://localhost:8899",
      rpcSubscriptionsUrl: "ws://localhost:8900"
    })
  )
  .use(rpcAirdrop())

const mint = await generateKeyPairSigner();
const burnAuthority = await generateKeyPairSigner();

const permissionedBurnExtension = extension("PermissionedBurn", {
  authority: burnAuthority.address
});

const mintSpace = BigInt(getMintSize([permissionedBurnExtension]));

const mintRent = await client.rpc
  .getMinimumBalanceForRentExemption(mintSpace)
  .send();

await client.sendTransaction([
  getCreateAccountInstruction({
    payer: client.payer,
    newAccount: mint,
    lamports: mintRent,
    space: mintSpace,
    programAddress: TOKEN_2022_PROGRAM_ADDRESS
  }),
  getInitializePermissionedBurnInstruction({
    mint: mint.address,
    authority: burnAuthority.address
  }),
  getInitializeMintInstruction({
    mint: mint.address,
    decimals: 0,
    mintAuthority: client.payer.address,
    freezeAuthority: client.payer.address
  })
]);

PermissionedBurnInstruction::Initialize must come before InitializeMint. CreateAccount, PermissionedBurnInstruction::Initialize, and InitializeMint must be included in the same transaction.

Source Reference

Item	Description	Source
`PermissionedBurnConfig`	Mint extension that stores the authority required to co-sign every burn for the mint.	Source
`PermissionedBurnInstruction::Initialize`	Instruction that initializes the permissioned burn config before `InitializeMint`.	Source
`PermissionedBurnInstruction::Burn`	Burn instruction that requires signatures from the burn authority and the token account owner or delegate.	Source
`PermissionedBurnInstruction::BurnChecked`	Burn instruction with a decimals check that uses the same accounts as `PermissionedBurnInstruction::Burn`.	Source
`AuthorityType::PermissionedBurn`	Authority discriminator used with `SetAuthority` to rotate or disable the burn authority on a mint.	Source
`process_initialize`	Processor logic that initializes `PermissionedBurnConfig` on an uninitialized mint and stores the burn authority.	Source
`process_burn`	Processor logic that rejects standard burns when the burn authority is set and verifies the authority's signature.	Source
`process_set_authority`	Processor logic that validates and rotates the burn authority when `AuthorityType::PermissionedBurn` is used.	Source

Typescript

The Kit example below uses the generated instructions directly. The published legacy @solana/spl-token package does not include permissioned burn support yet, so no legacy example is included.
