Τι Είναι ένα Mint με Δυνατότητα Παύσης;

Η επέκταση mint PausableConfig του Token Extensions Program παρέχει στην εξουσιοδότηση παύσης τη δυνατότητα να διακόπτει και να συνεχίζει τη δραστηριότητα token για ολόκληρο το mint.

Όταν ένα mint βρίσκεται σε παύση, το Token Extensions Program απορρίπτει:

Μεταφορές
Εκδόσεις (Mints)
Καταστροφές (Burns)

Όταν το mint συνεχιστεί, αυτές οι εντολές λειτουργούν κανονικά ξανά.

Πώς να Δημιουργήσετε, Παύσετε και Συνεχίσετε ένα Mint

Για να δημιουργήσετε, παύσετε και συνεχίσετε ένα mint:

Υπολογίστε το μέγεθος του λογαριασμού mint και το rent που απαιτείται για το mint και την επέκταση PausableConfig.
Δημιουργήστε τον λογαριασμό mint με CreateAccount, αρχικοποιήστε το PausableConfig και αρχικοποιήστε το mint με InitializeMint.
Εκδώστε tokens και δημιουργήστε token accounts για το mint.
Χρησιμοποιήστε το Pause για να μπλοκάρετε τη δραστηριότητα token για το mint.
Χρησιμοποιήστε το Resume για να επιτρέψετε ξανά τη δραστηριότητα token.

Υπολογισμός μεγέθους λογαριασμού

Υπολογίστε το μέγεθος του λογαριασμού mint για το βασικό mint συν την επέκταση PausableConfig. Αυτό είναι το μέγεθος που χρησιμοποιείται στο CreateAccount.

Υπολογισμός rent

Υπολογίστε το rent χρησιμοποιώντας το μέγεθος που απαιτείται για το mint συν την επέκταση PausableConfig.

Δημιουργία του λογαριασμού mint

Δημιουργήστε το mint account με τον υπολογισμένο χώρο και lamports.

Αρχικοποίηση PausableConfig

Αρχικοποιήστε την επέκταση PausableConfig στο mint.

Αρχικοποίηση του mint

Αρχικοποιήστε το mint με InitializeMint στην ίδια συναλλαγή.

Παύση του mint

Θέστε το mint σε παύση με Pause.

Συνέχιση του mint

Συνεχίστε τη λειτουργία του mint με Resume.

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 pausableExtension = extension("PausableConfig", {
  authority: client.payer.address,
  paused: false
});

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

Σειρά Εντολών

Το PausableInstruction::Initialize πρέπει να προηγείται του InitializeMint. Τα CreateAccount, PausableInstruction::Initialize και InitializeMint πρέπει να συμπεριλαμβάνονται στην ίδια συναλλαγή.
