Overview

The Blockchain Events service watches contracts on supported chains, decodes the events you subscribe to, and delivers them to your webhook as signed payloads. Every endpoint requires a token with project + business context and a per-operation capability. See the Blockchain Events webhooks & capabilities guide for the capability matrix, supported networks, the event payload, and signature verification.
