Bounty #05: Webhook Relay for On-chain Events

Overview

Reward: $1,000

Difficulty: 🟢 Small

Timeline: 2-3 weeks

Type: Infrastructure, Event Monitoring, Webhook System

Problem Statement

Developers and applications need real-time notifications when specific events occur on Conflux eSpace contracts, but setting up event monitoring infrastructure is complex and time-consuming. There's a need for a simple, configurable service that can listen for blockchain events and relay them to external systems via webhooks.

Solution Overview

Develop a backend listener service that subscribes to specific eSpace contract events and sends formatted webhook payloads to configurable URLs when events match specified criteria. The service should include templates for popular automation platforms and provide comprehensive configuration options.
