Chain Registry

Goal

Chain-Registry is responsible for

• Storing chains’ related information including URL, name, block depth, block position, and backoff duration.

Chain Registry allows Orchestrate to access to the blockchain network JSON-RPC endpoint, to act as a proxy. And to asynchronously catch and process transaction receipts as transactions are mined on the network.

Quick-Start

The application can be configured through flags or environment variables, we can run the help run command line.

go run . help run

  orchestrate chain-registry run [flags]
