What is Chainrel?

Chainrel provides real‑time blockchain event notifications to backend services through webhooks, Slack, and Discord. It supports EVM chains such as Ethereum, Polygon, Binance Smart Chain, and Avalanche C‑Chain, with Optimism and Linea coming soon. Users can subscribe to events from specific contract addresses or via a factory contract that listens to all child contracts.

Block‑confirmation thresholds can be customized for secure transaction validation. Event data is parsed into ABI‑defined JSON, handling arrays, strings, integers, and structs. The platform includes a queue system to manage high event throughput and flexible notification channels for developers building DApps, DeFi platforms, or gaming projects.
