How to Connect to Cronos

It’s easy to connect to your Cronos infrastructure via RPC.

If you haven’t configured any Cronos infrastructure, visit the Cronos marketplace page to learn more about Blockdaemon’s Cronos options.

Once you have purchased your Blockdaemon Cronos infrastructure, your Blockdaemon Technical Account Manager (TAM) will send you the necessary access credentials.
