}

Drei leistungsstarke Integrationsarten

Automatisieren Sie kritische Benachrichtigungen direkt aus Ihren Smart Contracts.

Transaktionsbenachrichtigungen

Echtzeit‑BenachrichtigungenVerbessertes BenutzererlebnisReduzierte Support-Tickets

Automatisch Benutzer über erfolgreiche Transaktionen, fehlgeschlagene Versuche und ausstehende Bestätigungen informieren.

Häufige Anwendungsfälle:

  • DeFi swap confirmations with slippage details
  • NFT purchase receipts with marketplace links
  • Benachrichtigungen über beanspruchte Staking-Belohnungen
  • Fehlgeschlagene Transaktionswarnungen mit Gas-Schätzung
  • Aktualisierungen zum Abschluss der Cross‑Chain‑Brücke

DeFi Protocol Events

Liquidationen verhindernTVL des Protokolls erhöhenBessere Nutzerbindung

Informieren Sie die Nutzer über Ertragsfarming-Belohnungen, Liquidationsrisiken und Protokolländerungen.

Häufige Anwendungsfälle:

  • Auszahlungen von Yield‑Farming-Belohnungen
  • Liquidationswarnungen bei einem Sicherheitenverhältnis von 110 %
  • Neuer Pool startet mit Bonus‑APY
  • Erinnerungen zum Abstimmen über Governance‑Vorschläge
  • Änderungen und Aktualisierungen der Protokollgebühr

  • Aktualisierungen zu Treasury-Meilensteinen
Implementierungsbeispiel
// Notify on new governance proposal
function createProposal(string calldata description) external {
    uint256 proposalId = proposals.length;
    
    // ... create proposal logic ...
    
    // Email all token holders
    IMailBox(mailboxContract).sendBulkEmail(
        getAllTokenHolders(),
        "🗳️ New Governance Proposal",
        "governance-proposal",
        abi.encode(proposalId, description, block.timestamp + votingDelay)
    );
}

Erweiterte Funktionen

Mächtige Fähigkeiten für komplexe Anwendungsfälle

Bedingte Logik

E-Mails basierend auf komplexen On-Chain-Bedingungen senden

Beispiel:
Benachrichtige Benutzer nur, wenn ihre Positionsgröße mehr als 1.000 $ beträgt und der Gesundheitsfaktor unter 150 % fällt.

Massenoperationen

E-Mails an mehrere Benutzer in einer einzigen Transaktion senden

Beispiel:
Alle LP-Anbieter benachrichtigen, wenn ein neues Anreizprogramm gestartet wird

Vorlagenvariablen

Dynamische Inhalte basierend auf Transaktionsdaten

Beispiel:
Schließen Sie die Swap-Beträge, Gebühren, Slippage und Transaktions-Hash in den Bestätigungen ein.

Wiederholungslogik

Automatischer erneuter Versuch bei fehlgeschlagenen E-Mail-Zustellungen

Beispiel:
Wiederhole wichtige Benachrichtigungen bis zu 3 Mal mit exponentiellem Backoff.
