양도 불가능한 토큰

양도 불가능한 토큰이란?

Token Extensions Program의 NonTransferable mint 확장 기능은 해당 mint의 모든 token account를 양도 불가능하게 만듭니다. 토큰이 발행된 후 토큰 보유자는 Transfer 또는 *rsTransferChecked*를 사용하여 다른 token account로 이동할 수 없습니다.

이 패턴은 하나의 지갑에 고정되어야 하는 자산에 유용합니다.

양도 불가능한 토큰은 여전히 다음이 가능합니다:

mint 권한에 의한 발행
token account 소유자 또는 승인된 위임자에 의한 소각
잔액이 0이 된 후 token account 폐쇄

Token Account 확장 기능

_rsNonTransferable_가 있는 mint에 대해 token account가 초기화되면, token account는 NonTransferableAccount 및 _rsImmutableOwner_와 함께 초기화됩니다. Associated Token Program을 통해 token account가 생성되면 필요한 계정 크기가 계산되고 token account는 필요한 크기와 rent 면제 lamport로 생성됩니다.

양도 불가능한 Mint를 생성하는 방법

양도 불가능한 mint를 생성하려면:

mint 및 NonTransferable 확장 기능에 필요한 mint account 크기와 rent를 계산합니다.
*rsCreateAccount*로 mint account를 생성하고, *rsNonTransferable*를 초기화한 다음, *rsInitializeMint*로 mint를 초기화합니다.
mint에 대한 token account를 생성합니다. token account에 대해 NonTransferableAccount 및 *rsImmutableOwner*가 자동으로 활성화됩니다.
Transfer 및 *rsTransferChecked*는 TokenError::NonTransferable 오류로 실패합니다.

계정 크기 계산

기본 mint와 NonTransferable 확장 기능을 포함한 mint account 크기를 계산합니다. 이것이 *rsCreateAccount*에서 사용되는 크기입니다.

렌트 계산

민트에 필요한 크기와 NonTransferable 확장을 사용하여 렌트를 계산합니다.

mint account 생성

계산된 공간과 lamport로 mint account를 생성합니다.

NonTransferable 초기화

민트에서 NonTransferable 확장을 초기화합니다.

민트 초기화

동일한 트랜잭션에서 *rsInitializeMint*를 사용하여 민트를 초기화합니다.

계정 크기 계산

기본 mint와 NonTransferable 확장 기능을 포함한 mint account 크기를 계산합니다. 이것이 *rsCreateAccount*에서 사용되는 크기입니다.

렌트 계산

민트에 필요한 크기와 NonTransferable 확장을 사용하여 렌트를 계산합니다.

mint account 생성

계산된 공간과 lamport로 mint account를 생성합니다.

NonTransferable 초기화

민트에서 NonTransferable 확장을 초기화합니다.

민트 초기화

동일한 트랜잭션에서 *rsInitializeMint*를 사용하여 민트를 초기화합니다.

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 recipient = await generateKeyPairSigner();

const nonTransferableExtension = extension("NonTransferable", {});

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

명령어 순서

_rsInitializeNonTransferableMint_는 _rsInitializeMint_보다 먼저 실행되어야 합니다. CreateAccount, InitializeNonTransferableMint, 그리고 _rsInitializeMint_는 동일한 트랜잭션에 포함되어야 합니다.

소스 참조

항목	설명	소스
`NonTransferable`	민트의 토큰을 양도 불가능으로 표시하는 민트 확장입니다.	소스
`NonTransferableAccount`	양도 불가능 민트를 위한 token account에 추가되는 token account 확장입니다.	소스
`ImmutableOwner`	소유권 변경을 방지하며 양도 불가능 token account에 필수적인 token account 확장입니다.	소스
`InitializeNonTransferableMint`	`InitializeMint` 이전에 민트 수준의 양도 불가능 확장을 초기화하는 명령어입니다.	소스
`process_initialize_non_transferable_mint`	초기화되지 않은 민트에서 `NonTransferable` 민트 확장을 초기화하는 프로세서 로직입니다.	소스
`get_required_init_account_extensions`	민트에서 활성화된 확장을 기반으로 token account가 초기화될 때 token account 확장을 자동으로 추가하는 데 사용됩니다. `NonTransferable` 민트의 경우 rs`NonTransferableAccount`와 rs`ImmutableOwner`를 추가합니다.	소스
