Créer un compte de jetons

Qu'est-ce qu'un token account ?

Un token account stocke votre solde d'un jeton spécifique. Chaque token account est associé à exactement un mint et suit votre solde de jetons ainsi que des détails supplémentaires.

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 Token Program et le Token Extension Program partagent la même implémentation de base pour le token account.

Pour détenir des jetons, vous avez besoin d'un token account pour ce mint spécifique. Chaque token account suit :

Mint : Le type de jeton spécifique qu'il contient
Owner : L'autorité qui peut transférer des jetons depuis ce compte

Exemple : USD Coin (USDC)

Adresse du mint : EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v
Token account de Circle : 3emsAVdmGKERbHjmGfQ6oZ1e35dkf5iYcS6U4CPKFVaa
Ce compte ne contient que des jetons USDC
Circle contrôle les jetons via l'autorité propriétaire du token account : 7VHUFJHWu2CuExkJcJrzhQPJ2oygupTWkL2A2For4BmE

Vous pouvez consulter les détails de ce token account sur Solana Explorer.

Comprendre la terminologie "Owner"

Le terme "owner" peut être utilisé dans deux contextes différents :

Propriétaire du token account : L'autorité qui peut transférer, brûler ou déléguer des jetons. Ceci est stocké dans les données du token account.
Programme propriétaire : Le programme qui possède le compte (toujours le Token Program ou Token Extension Program pour les token accounts).

Lorsqu'on travaille avec des token accounts, "owner" fait généralement référence à l'autorité qui peut transférer des jetons, et non au programme qui possède le compte.

Qu'est-ce qu'un associated token account ?

Un associated token account (ATA) est le token account par défaut pour un portefeuille destiné à détenir un jeton spécifique. Il utilise une adresse déterministe (PDA) créée par l' Associated Token Program.

Seuls les token accounts créés par l'Associated Token Program sont appelés "associated token accounts."

Les ATA utilisent des adresses déterministes, ce qui facilite la recherche du token account de n'importe quel portefeuille pour un mint donné. Voir 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
    )
}

Pour toute combinaison de portefeuille et de jeton, il existe exactement une adresse ATA. Cela élimine la nécessité de suivre manuellement les adresses des token accounts—vous pouvez toujours dériver l'adresse correcte.

Comment fonctionne l'Associated Token Program

L'Associated Token Program est un assistant qui :

Crée des comptes de jetons à des adresses déterministes (PDAs)
Effectue des Cross Program Invocations (CPIs) vers le Token Program
Ne maintient aucun état par lui-même

Les comptes de jetons résultants appartiennent au Token Program et utilisent la structure standard Account.

Comment créer un compte de jetons

La création d'un compte de jetons nécessite l'instruction InitializeAccount. Voir l'implémentation ici.

Vous avez besoin de deux instructions pour créer un compte de jetons :

System Program : Créer un compte avec l'espace alloué pour un compte de jetons et transférer la propriété au Token Program
Token Program : Initialiser les données du compte de jetons

Comment créer un associated token account
