So senden Sie SPL-Tokens

Verwenden Sie das Token-Programmopen in new window, um SPL-Token zu übertragen. Um ein SPL-Token zu senden, müssen Sie die Kontoadresse des SPL-Tokens kennen. Sie können sowohl die Adresse abrufen als auch Token senden mit folgendem Beispiel.

So berechnen Sie die Transaktionskosten

Zur Berechnung wird die Anzahl der Unterschriften der Transaktionskosten, die eine Transaktion benötigt herangezogen. Solange Sie kein Konto erstellen, werden dies die endgültigen Transaktionskosten sein. Um mehr über die Erstellungskosten eines Konto zu erfahren , siehe Berechnung der Mietbefreiung

Die beiden folgenden Beispiele zeigen die beiden derzeit verfügbaren Möglichkeiten zur Berechnung der geschätzten Transaktionskosten.

Das erste Beispiel verwendet „getEstimatedFee“, eine neue Methode in der Klasse „Transaction“, während das zweite Beispiel „getFeeForMessage“ verwendet, das „getFeeCalculatorForBlockhash“ in der Klasse „Connection“ ersetzt.

So fügen Sie einer Transaktion eine Notiz hinzu

Jede Transaktion kann unter Verwendung des [Memo-Programms] 2open in new window eine Nachricht hinzufügen. Aktuell muss noch die programID aus dem Memo-Programm hinzugefügt werden manuell MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr.

So ändern Sie das Computing-Budget, die Gebühr & Priorität für eine Transaktion

Die Transaktionspriorität (TX) wird zusätzlich zur Grundgebühr durch die Zahlung einer Priorisierungsgebühr erreicht. Standardmäßig ist das Rechenbudget das Produkt von 200.000 Compute Units (CU) * Anzahl der Anweisungen, mit einem Maximum von 1,4 Mio. CU. Die Grundgebühr beträgt 5.000 Lamports. Ein microLamport ist 0,000001 Lamport.

Das Gesamtrechenbudget oder die Priorisierungsgebühr für eine einzelne TX kann umgeändert werden. Hinzufügen von Anweisungen aus dem ComputeBudgetProgram.

ComputeBudgetProgram.setComputeUnitPrice({ microLamports: Zahl }) wird eine Priorisierungsgebühr über der Grundgebühr (5.000 Lamports) hinzugefügt. Um das zu bestimmen Der Wert der Priorisierungsgebühr in Lamports die in microLamports bereitgestellt werden, werden mit dem CU-Budget multipliziert. Wenn Ihr CU-Budget beispielsweise 1 Mio. CU beträgt, und Sie Fügen Sie 1 microLamport/CU hinzu, beträgt die Priorisierungsgebühr 1 Lamport (1M * 0,000001). Die Gesamtgebühr beträgt dann 5001 Lamports.

Verwenden Sie zum Festlegen „ComputeBudgetProgram.setComputeUnitLimit({units: number})“. das neue Compute-Budget. Der angegebene Wert ersetzt den Standardwert. Transaktionen sollten die erforderliche Mindestmenge an CU anfordern Ausführung, um den Durchsatz zu maximieren oder Gebühren zu minimieren.
