}
Tres tipos de integración potentes
Automatiza las comunicaciones críticas con usuarios directamente desde tus contratos inteligentes
Notificaciones de transacciones
Notificaciones en tiempo realMejorar la experiencia del usuarioTickets de soporte reducidos
Notifique automáticamente a los usuarios sobre transacciones exitosas, intentos fallidos y confirmaciones pendientes.
Casos de uso comunes:
- DeFi swap confirmations with slippage details
- NFT purchase receipts with marketplace links
- Notificaciones de recompensas de staking reclamadas
- Alertas de transacciones fallidas con estimación de gas
- Actualizaciones sobre la finalización del puente intercadena

DeFi Protocol Events
Prevenir liquidacionesAumentar el TVL del protocoloMejor retención de usuarios
Mantén a los usuarios informados sobre las recompensas de yield farming, riesgos de liquidación y cambios en el protocolo.
Casos de uso comunes:
- Distribuciones de recompensas en yield farming
- Advertencias de liquidación al 110% del ratio de colateral
- Nuevo lanzamiento de pool con rendimiento anual (APY) de bonificación
- Recordatorios de votación de propuestas de gobernanza
- Cambios y actualizaciones de la tarifa del protocolo

Funciones Avanzadas
Capacidades potentes para casos de uso complejos
Lógica condicional
Enviar correos electrónicos basados en condiciones complejas en cadena.
Ejemplo:
Solo notificar a los usuarios si su tamaño de posición excede $1,000 y el factor de salud cae por debajo del 150%.
Operaciones por lotes
Envíe correo electrónico a varios usuarios en una sola transacción.
Ejemplo:
Notificar a todos los proveedores de LP cuando se lance un nuevo programa de incentivos.
Variables de plantilla
Contenido dinámico basado en datos de transacciones
Ejemplo:
Incluya los montos de intercambio, tarifas, deslizamiento y hash de la transacción en las confirmaciones.
Lógica de reintentos
Reintento automático para entregas de correo electrónico fallidas
Ejemplo:
Reintentar las notificaciones importantes hasta 3 veces con retroceso exponencial
