Chainrel – Unlocking Blockchain Events with Ease

Chainrel empowers your backend service with seamless blockchain event integration. It provides a flexible, language-agnostic way to listen to and deliver blockchain events to your backend, enabling real-time notifications and automation across your workflows.

Overview

  • Independent: Your backend services run independently of the blockchain programming languages you use.
  • Customize: Import events with a verified contract address or an ABI file. Predefined events for ERC-20, ERC-721, and ERC-1155 are supported.
  • Safety: You can choose the block confirmation value you consider safe for transaction verification.
  • Easy to use: Factory contract listening and wallet transfer events are supported, simplifying listening to events from your own deployments.

How It Works

  • Listen to blockchain events from supported networks and forward them to your webhook endpoints or integration channels.
  • Parse event data into structured formats and deliver via abi json variable names.
  • Use the block confirmation value to balance speed and safety for your use case.
  • Import events via contract address or ABI, and opt into listening to multiple contracts or to all contracts on a given network.

Supported Chains

  • Ethereum mainnet and Goerli testnet
  • Polygon mainnet and Mumbai testnet
  • Binance Smart Chain mainnet and testnet
  • Avalanche C-Chain mainnet and Fuji testnet
  • Optimism soon
  • Linea soon

If your network isn’t listed, you can request support.
