Trois types d’intégration puissants

Automatisez les communications critiques aux utilisateurs directement depuis vos contrats intelligents

Notifications de transaction

Notifications en temps réelExpérience utilisateur amélioréeTickets de support réduits

Notifiez automatiquement les utilisateurs des transactions réussies, des tentatives échouées et des confirmations en attente.

Cas d’utilisation courants :

  • DeFi swap confirmations with slippage details
  • NFT purchase receipts with marketplace links
  • Notifications de réclamation des récompenses de staking
  • Alertes de transactions échouées avec estimation du gaz
  • Mises à jour sur l’achèvement du pont inter-chaînes
