Δημιουργία ενός Token Account

Τι είναι ένα Token Account;

Ένα token account αποθηκεύει το υπόλοιπό σας σε ένα συγκεκριμένο token. Κάθε token account συνδέεται με ακριβώς ένα mint και παρακολουθεί το υπόλοιπο των token σας και πρόσθετες λεπτομέρειες.

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>,

}

Σημειώστε ότι στον πηγαίο κώδικα, οι προγραμματιστές αποκαλούν ένα Token account ως τύπο Account. Τόσο το Token Program όσο και το Token Extension Program μοιράζονται την ίδια βασική υλοποίηση για το Token account.

Για να διατηρήσετε tokens, χρειάζεστε ένα token account για αυτό το συγκεκριμένο mint. Κάθε token account παρακολουθεί:

  1. Mint: Τον συγκεκριμένο τύπο token που διατηρεί
  2. Owner: Την αρχή που μπορεί να μεταφέρει tokens από αυτόν τον λογαριασμό

Παράδειγμα: USD Coin (USDC)

  • Διεύθυνση mint: EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v
  • Token account της Circle: 3emsAVdmGKERbHjmGfQ6oZ1e35dkf5iYcS6U4CPKFVaa
  • Αυτός ο λογαριασμός διατηρεί μόνο USDC tokens
  • Η Circle ελέγχει τα token μέσω της αρχής ιδιοκτήτη του token account: 7VHUFJHWu2CuExkJcJrzhQPJ2oygupTWkL2A2For4BmE

Μπορείτε να δείτε τις λεπτομέρειες αυτού του token account στον Solana Explorer.

Κατανόηση της ορολογίας "Owner"

Ο όρος "owner" μπορεί να χρησιμοποιηθεί σε δύο διαφορετικά πλαίσια:

  1. Token Account Owner: Η αρχή που μπορεί να μεταφέρει, να κάψει ή να αναθέσει tokens. Αυτό αποθηκεύεται στα δεδομένα του token account.

  2. Program Owner: Το πρόγραμμα που κατέχει τον λογαριασμό (πάντα το Token Program ή το Token Extension Program για token accounts).

Όταν εργάζεστε με token accounts, ο "owner" συνήθως αναφέρεται στην αρχή που μπορεί να μεταφέρει tokens, όχι στο πρόγραμμα που κατέχει τον λογαριασμό.

Τι είναι ένα Associated Token Account;

Ένα associated token account (ATA) είναι το προεπιλεγμένο token account για ένα πορτοφόλι για τη διατήρηση ενός συγκεκριμένου token. Χρησιμοποιεί μια ντετερμινιστική διεύθυνση (PDA) που δημιουργείται από το Associated Token Program.

Μόνο τα token accounts που δημιουργούνται από το Associated Token Program ονομάζονται "associated token accounts."

Τα ATAs χρησιμοποιούν ντετερμινιστικές διευθύνσεις, καθιστώντας εύκολη την εύρεση του token account οποιουδήποτε πορτοφολιού για ένα δεδομένο mint. Δείτε την υλοποίηση παραγωγής εδώ.

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

    )

}

Για οποιονδήποτε συνδυασμό πορτοφολιού και token, υπάρχει ακριβώς μία διεύθυνση ATA. Αυτό εξαλείφει την ανάγκη χειροκίνητης παρακολούθησης των διευθύνσεων token account—μπορείτε πάντα να παράγετε τη σωστή διεύθυνση.

Πώς λειτουργεί το Associated Token Program

Το Associated Token Program είναι ένα βοηθητικό πρόγραμμα που:

  • Δημιουργεί token accounts σε προκαθορισμένες διευθύνσεις (PDAs)
  • Πραγματοποιεί Cross-Program Invocations (CPIs) στο Token Program
  • Δεν διατηρεί καμία κατάσταση από μόνο του

Τα token accounts που δημιουργούνται ανήκουν στο Token Program και χρησιμοποιούν την τυπική δομή Account.

Πώς να δημιουργήσετε ένα Token Account

Η δημιουργία ενός token account απαιτεί την εντολή InitializeAccount. Δείτε την υλοποίηση εδώ.

Χρειάζεστε δύο εντολές για να δημιουργήσετε ένα token account:

  1. System Program: Δημιουργία λογαριασμού με κατανεμημένο χώρο για ένα token account και μεταφορά ιδιοκτησίας στο Token Program
  2. Token Program: Αρχικοποίηση των δεδομένων του token account
