Chainrel

Chainrel is a developer tool for tracking events on Ethereum and other EVM-compatible blockchains without having to build and maintain custom polling infrastructure. Instead of repeatedly querying a blockchain node for new activity, developers configure Chainrel to watch specific contracts and receive a notification the moment a relevant event occurs. Users can define what to watch in a few ways: by pointing Chainrel at a verified contract address, by importing a contract's ABI as a JSON file, or by selecting one of the predefined templates for common standards like ERC-20, ERC-721, and ERC-1155. Once configured, notifications can be routed to a backend URL as a webhook, or sent directly to services like Slack or Discord, which the company highlights as a way for communities to get real-time alerts about mint events, transfers, or other on-chain activity. Chainrel has also published guides showing the service used for narrower cases, such as tracking newly registered ENS domains. The product is aimed at developers, DeFi applications, and NFT projects that need reliable event data without deep blockchain infrastructure expertise. Public information about Chainrel is limited mostly to its own site and blog posts, so details on pricing, supported chains beyond Ethereum, and company background are not clearly documented.
