권한 있는 소각이란?
Token Extensions Program의 PermissionedBurnConfig 민트 확장은 해당 민트의
모든 소각에 설정된 소각 권한자의 공동 서명을 요구합니다.
소각 권한자가 설정되어 있는 동안:
- 표준
Burn및BurnChecked명령어는TokenError::InvalidInstruction오류와 함께 실패합니다. - 소각 시
PermissionedBurnInstruction::Burn또는 *rsPermissionedBurnInstruction::BurnChecked*을 사용해야 하며, 소각 권한자와 token account의 소유자 또는 위임자 모두의 서명이 필요합니다.
소각 권한자는 소유자를 대체하는 것이 아니라 공동 서명자입니다. 권한자 단독으로는 타인의 token account에서 토큰을 소각할 수 없으며, token account 소유자도 권한자의 서명 없이는 소각할 수 없습니다. 영구 위임자도 권한 있는 소각 명령어를 사용해야 하며, 소각 권한자의 공동 서명이 여전히 필요합니다.
이를 통해 발행자는 토큰 공급량을 오프체인 기록과 동기화할 수 있습니다. 예를 들어, 1:1 담보를 유지해야 하는 토큰화 자산의 경우 보유자가 일방적으로 토큰을 소각하는 것을 방지할 수 있습니다.
소각 권한자는 나중에 *rsAuthorityType::PermissionedBurn*를 사용하여
*rsSetAuthority*로 교체할 수 있습니다. 권한자를 None로 설정하면 권한 있는
소각이 비활성화되고 표준 소각 명령어가 다시 활성화됩니다. 확장 데이터 자체는
민트에 그대로 유지됩니다.
사용 가능 여부
권한 있는 소각은 Token-2022
program@v11.0.0에
포함되어 출시됩니다. 현재 devnet에서 사용 가능하며, 2026년 6월 메인넷 활성화가
예정되어 있습니다. Token Extension Program은 각 클러스터에 별도로 배포되므로,
대상 클러스터의 배포 버전이 v11.0.0 이상인지 확인하세요.
로컬 테스트 validator에는 이전 버전의 Token-2022 빌드가 포함되어 있으므로, 이 페이지의 예제를 실행하려면 devnet에서 v11.0.0 프로그램을 테스트 validator에 로드하세요:
solana program dump -u devnet TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb token_2022.sosolana-test-validator --reset --bpf-program TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb token_2022.so
권한 있는 소각으로 Mint 생성 및 소각하는 방법
권한 있는 소각으로 mint를 생성하고 토큰을 소각하려면:
- mint account 크기와 mint 및
PermissionedBurnConfig확장에 필요한 rent를 계산합니다. - *rs
CreateAccount*로 mint account를 생성하고, *rsPermissionedBurnConfig*를 초기화한 후, *rsInitializeMint*로 mint를 초기화합니다. - token account를 생성하고 토큰을 발행합니다.
- token account 소유자와 소각 권한자가 모두 서명한
*rs
PermissionedBurnInstruction::BurnChecked*로 소각합니다. - 선택적으로 *rs
AuthorityType::PermissionedBurn*와None권한자를 사용하여 *rsSetAuthority*로 권한 있는 소각을 비활성화하면 표준 소각 명령어가 다시 활성화됩니다. 아래의 전체 코드 예제에서 이 단계를 확인할 수 있습니다.
계정 크기 계산
기본 mint와 PermissionedBurnConfig 확장을 위한 mint account 크기를
계산합니다. 이 크기는 *rsCreateAccount*에서 사용됩니다.
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]));
rent 계산
mint와 PermissionedBurnConfig 확장에 필요한 크기를 사용하여 rent를
계산합니다.
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();
mint account 생성
계산된 공간과 lamport로 mint account를 생성합니다.
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})]);
PermissionedBurn 초기화
소각 권한자로 mint에 PermissionedBurnConfig 확장을 초기화합니다.
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})]);
mint 초기화
동일한 트랜잭션에서 *rsInitializeMint*로 mint를 초기화합니다.
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}),getInitializeMintInstruction({mint: mint.address,decimals: 0,mintAuthority: client.payer.address,freezeAuthority: client.payer.address})]);
token account 생성 및 토큰 발행
지불자를 위한 token account를 생성하고 토큰을 발행합니다.
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}),getInitializeMintInstruction({mint: mint.address,decimals: 0,mintAuthority: client.payer.address,freezeAuthority: client.payer.address})]);const [sourceToken] = await findAssociatedTokenPda({mint: mint.address,owner: client.payer.address,tokenProgram: TOKEN_2022_PROGRAM_ADDRESS});await client.sendTransaction([await getCreateAssociatedTokenInstructionAsync({payer: client.payer,mint: mint.address,owner: client.payer.address}),getMintToCheckedInstruction({mint: mint.address,token: sourceToken,mintAuthority: client.payer,amount: 2n,decimals: 0})]);
소각 권한으로 소각
token account 소유자와 소각 권한자 모두가 서명한
*rsPermissionedBurnInstruction::BurnChecked*로 토큰을 소각합니다.
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}),getInitializeMintInstruction({mint: mint.address,decimals: 0,mintAuthority: client.payer.address,freezeAuthority: client.payer.address})]);const [sourceToken] = await findAssociatedTokenPda({mint: mint.address,owner: client.payer.address,tokenProgram: TOKEN_2022_PROGRAM_ADDRESS});await client.sendTransaction([await getCreateAssociatedTokenInstructionAsync({payer: client.payer,mint: mint.address,owner: client.payer.address}),getMintToCheckedInstruction({mint: mint.address,token: sourceToken,mintAuthority: client.payer,amount: 2n,decimals: 0})]);await client.sendTransaction([getPermissionedBurnCheckedInstruction({account: sourceToken,mint: mint.address,permissionedBurnAuthority: burnAuthority,authority: client.payer,amount: 1n,decimals: 0})]);
명령어 순서
_rsPermissionedBurnInstruction::Initialize_은 InitializeMint 이전에
와야 합니다. CreateAccount,
PermissionedBurnInstruction::Initialize, _rsInitializeMint_은 동일한
트랜잭션에 포함되어야 합니다.
