Chainrel

Chainrel is a webhook service that connects blockchain activity directly to your backend systems. It listens for specific events on supported EVM chains—like Ethereum, Polygon, and Binance Smart Chain—and sends instant notifications to a URL you specify. This means you can track NFT sales, token transfers, DeFi orders, or game actions without running your own blockchain node or writing complex listener code. You set up what to watch for, and Chainrel handles the data parsing and delivery.

The tool works by letting you import events using a verified contract address or an ABI file. You can also use predefined templates for common standards like ERC-20, 721, and 1155. A key feature is control over safety: you can set how many block confirmations are required before an event is considered final, guarding against blockchain reorganizations. It also simplifies monitoring for projects using Factory contracts, letting you listen to events from all child contracts created through a single parent.

Chainrel is built for developers and teams building on blockchain. It removes the infrastructure burden of tracking on-chain activity, so they can focus on their core application logic. Practical uses include building dashboards that update live with user activity, automating backend processes triggered by on-chain events, or keeping a team informed via Slack or Discord channels when important transactions occur.
