Créer un compte de jetons

Qu'est-ce qu'un compte de jetons ?

Un compte de jetons est un type de compte dans les programmes de jetons de Solana qui stocke des informations sur la propriété d'un jeton spécifique (mint) par un individu. Chaque compte de jetons est associé à un seul mint et suit des détails comme le solde de jetons et le propriétaire.

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>,
}

Notez que dans le code source, les développeurs appellent un compte de jetons un type Account. Le Programme de Jetons et le Programme d'Extension de Jetons partagent la même implémentation de base pour le compte de jetons.

Pour détenir des jetons d'un mint spécifique, les utilisateurs doivent d'abord créer un compte de jetons. Chaque compte de jetons garde une trace de :

Un mint spécifique (le type de jeton que le compte de jetons détient)
Un propriétaire (l'autorité qui peut transférer des jetons depuis le compte)

Voici un exemple utilisant USD Coin (USDC) sur Solana :

L'adresse du mint USD Coin : EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v
Circle (l'émetteur de USD Coin) possède un compte de jetons à 3emsAVdmGKERbHjmGfQ6oZ1e35dkf5iYcS6U4CPKFVaa
Ce compte de jetons ne détient que des unités du jeton USD Coin (mint)
Circle a l'autorité de propriétaire à 7VHUFJHWu2CuExkJcJrzhQPJ2oygupTWkL2A2For4BmE et peut transférer ces jetons

Vous pouvez consulter les détails de ce compte de jetons sur Solana Explorer.

Le terme "propriétaire" est utilisé dans deux contextes différents :

Le "propriétaire" du compte de jetons - Il s'agit d'une adresse stockée dans les données du compte de jetons comme champ "owner" du type Account défini par le Programme de Jetons. Le propriétaire peut transférer, brûler ou déléguer des jetons depuis le compte. Cette adresse est parfois appelée "autorité" du compte de jetons pour la distinguer du propriétaire du programme.
Le "propriétaire" du programme - Ceci fait référence au programme qui possède les données du compte sur Solana. Pour les comptes de jetons, il s'agit toujours soit du Programme de Jetons (Token Program) soit du Programme d'Extension de Jetons (Token Extension Program), comme spécifié dans le champ "owner" du type Account de base de Solana.

Lorsqu'on travaille avec des comptes de jetons, "propriétaire" fait généralement référence à l'autorité qui peut dépenser les jetons, et non au programme qui possède le compte.

Qu'est-ce qu'un Compte de Jetons Associé ?

Un compte de jetons associé est un compte de jetons dont l'adresse est une Adresse Dérivée de Programme (PDA) créée par le Programme de Jetons Associés. Vous pouvez considérer un compte de jetons associé comme le compte de jetons par défaut pour un utilisateur détenant des unités d'un jeton spécifique (mint).

Le terme "comptes de jetons associés" s'applique uniquement aux comptes de jetons que le Programme de Jetons Associés crée.

Les comptes de jetons associés fournissent une méthode déterministe pour trouver le compte de jetons d'un utilisateur pour n'importe quel mint donné. Vous pouvez examiner l'implémentation de la dérivation ici.

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
    )
}

Cette dérivation déterministe garantit que pour toute combinaison d'adresse de portefeuille et de mint de jeton, il existe exactement une adresse de compte de jetons associé. Cette approche simplifie la recherche du compte de jetons d'un utilisateur pour n'importe quel mint de jeton, éliminant ainsi la nécessité de suivre séparément les adresses de comptes de jetons.

Le Programme de Jetons Associés fonctionne comme un programme auxiliaire qui crée des comptes de jetons avec des adresses déterministes (PDAs). Lors de la création d'un compte de jetons associé, le Programme de Jetons Associés effectue un CPI (Invocation Inter-Programme) vers soit le Programme de Jetons soit le Programme d'Extension de Jetons. Le programme de jetons possède le compte créé qui a la même structure de type Account que celle définie dans le programme de jetons. Le Programme de Jetons Associés ne maintient aucun état - il offre simplement une façon standardisée de créer des comptes de jetons à une adresse déterministe qui est une PDA.

Comment créer un compte de jetons

Pour créer un compte de jetons, invoquez l'instruction InitializeAccount. Vous pouvez trouver des implémentations de cette instruction ici.

La transaction pour créer un compte de jetons nécessite deux instructions :

Invoquer le programme système pour créer et allouer de l'espace pour un compte de jetons et transférer la propriété au programme de jetons.
Invoquer le programme de jetons pour initialiser les données du compte de jetons.

Comment créer un compte de jetons associé

Pour créer un compte de jetons associé, invoquez l'instruction Create. Vous pouvez trouver des implémentations de cette instruction ici.

L'instruction pour créer un compte de jetons associé invoque automatiquement le programme système pour créer le compte de jetons et invoque le programme de jetons pour initialiser les données du compte de jetons. Cela se produit via des invocations inter-programmes (CPI).
