Chainrel provides real-time blockchain event notifications for seamless backend integration, keeping you updated instantly, and routing notifications to various channels like Slack, Discord, and webhooks. It empowers backend services with easy blockchain event integration, allowing them to run independently of blockchain programming languages. Chainrel supports customizable event imports from verified contracts or ABI files, including predefined ERC-20, 721, and 1155 events.

To use Chainrel, sign up for an account and configure webhooks to listen for specific blockchain events. Import events using a contract address, an ABI file, or by selecting predefined ERC standards.
