토큰 계정 생성하기

토큰 계정이란 무엇인가요?

토큰 계정은 특정 토큰의 잔액을 저장합니다. 각 토큰 계정은 정확히 하나의 민트와 연결되어 있으며 토큰 잔액과 추가 세부 정보를 추적합니다.

Token Account Type
/// Account data.

#[repr(C)]

#[derive(Clone, Copy, Debug, Default, PartialEq)]

pub struct Account {

    /// The mint associated with this account

    pub mint: Pubkey,

    /// The owner of this account.

    pub owner: Pubkey,

    /// The amount of tokens this account holds.

    pub amount: u64,

    /// If `delegate` is `Some` then `delegated_amount` represents

    /// the amount authorized by the delegate

    pub delegate: COption<Pubkey>,

    /// The account's state

    pub state: AccountState,

    /// If `is_native.is_some`, this is a native token, and the value logs the

    /// rent-exempt reserve. An Account is required to be rent-exempt, so

    /// the value is used by the Processor to ensure that wrapped SOL

    /// accounts do not drop below this threshold.

    pub is_native: COption<u64>,

    /// The amount delegated

    pub delegated_amount: u64,

    /// Optional authority to close the account.

    pub close_authority: COption<Pubkey>,

}

소스 코드에서 개발자들은 토큰 계정을 Account 타입이라고 부릅니다. Token Program과 Token Extensions Program 모두 토큰 계정에 대해 동일한 기본 구현을 공유합니다.

토큰을 보유하려면 해당 민트에 대한 토큰 계정이 필요합니다. 각 토큰 계정은 다음을 추적합니다:

  1. 민트: 보유하는 특정 토큰 유형
  2. 소유자: 이 계정에서 토큰을 전송할 수 있는 권한을 가진 주체

예시: USD 코인 (USDC)

  • 민트 주소: EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v
  • Circle의 토큰 계정: 3emsAVdmGKERbHjmGfQ6oZ1e35dkf5iYcS6U4CPKFVaa
  • 이 계정은 USDC 토큰만 보유합니다
  • Circle은 토큰 계정 소유자 권한을 통해 토큰을 제어합니다: 7VHUFJHWu2CuExkJcJrzhQPJ2oygupTWkL2A2For4BmE

솔라나 익스플로러에서 이 토큰 계정의 세부 정보를 볼 수 있습니다.

"소유자" 용어 이해하기

"소유자"라는 용어는 두 가지 다른 맥락에서 사용될 수 있습니다:

  1. 토큰 계정 소유자: 토큰을 전송, 소각 또는 위임할 수 있는 권한을 가진 주체입니다. 이는 토큰 계정의 데이터에 저장됩니다.

  2. 프로그램 소유자: 계정을 소유한 프로그램(토큰 계정의 경우 항상 Token Program 또는 Token Extensions Program)입니다.

토큰 계정을 다룰 때 "소유자"는 일반적으로 계정을 소유한 프로그램이 아닌 토큰을 전송할 수 있는 권한을 가진 주체를 의미합니다.

Associated Token Account란 무엇인가요?

Associated token account(ATA)는 지갑이 특정 토큰을 보유하기 위한 기본 토큰 계정입니다. 이는 Associated Token Program에 의해 생성된 결정론적 주소(PDA)를 사용합니다.

Associated Token Program에 의해 생성된 토큰 계정만이 "associated token accounts"라고 불립니다.

ATA는 결정론적 주소를 사용하여 주어진 민트에 대한 지갑의 토큰 계정을 쉽게 찾을 수 있게 합니다. 여기에서 파생 구현을 확인하세요.

Associated Token Account Address Derivation
pub fn get_associated_token_address_and_bump_seed_internal(

    wallet_address: &Pubkey,

    token_mint_address: &Pubkey,

    program_id: &Pubkey,

    token_program_id: &Pubkey,

) -> (Pubkey, u8) {

    Pubkey::find_program_address(

        &[

            &wallet_address.to_bytes(), // Owner's public key

            &token_program_id.to_bytes(), // Token Program or Token Extension Program

            &token_mint_address.to_bytes(), // Token mint address

        ],

        program_id, // Associated Token Program ID

    )

}

모든 지갑과 토큰 조합에 대해 정확히 하나의 ATA 주소가 있습니다. 이로 인해 토큰 계정 주소를 수동으로 추적할 필요가 없어집니다—항상 올바른 주소를 도출할 수 있습니다.

Associated Token Program의 작동 방식

Associated Token Program은 다음과 같은 도우미 역할을 합니다:

  • 결정론적 주소(PDA)에 토큰 계정 생성
  • Token Program에 Cross-Program Invocation(CPI) 수행
  • 자체적으로 상태를 유지하지 않음

결과적으로 생성된 토큰 계정은 Token Program이 소유하며 표준 Account 구조를 사용합니다.

토큰 계정을 생성하는 방법

토큰 계정을 생성하려면 InitializeAccount 명령이 필요합니다. 여기에서 구현을 확인하세요.

토큰 계정을 생성하려면 두 가지 명령이 필요합니다:

  1. System Program: 토큰 계정을 위한 공간이 할당된 계정을 생성하고 소유권을 Token Program에 이전
  2. Token Program: 토큰 계정 데이터 초기화
