Before you publish the integration

Use a reachable address

The generated code uses this site’s origin. A loopback address works only on the computer hosting the site.

Keep networks visible

Show the selected asset and network together so recipients can confirm compatibility.

Keep secrets on your server

Local account keys and provider credentials should never be inserted into a public embed.
