Apply with your domain. If your anchor passes the checks below, it is measured every 20 minutes like every other anchor, and its score card is published on-chain. An anchor that stops answering for a week is checked every six hours instead, until it answers again. Nothing else is asked of you: everything is read from your stellar.toml and the public network, and nothing here moves funds.
An anchor that only distributes someone else’s asset (USDC, for instance) has no asset of its own to age or count, so it is admitted on the first five checks.
