Key hygiene you can read off the ledger.

On a public ledger, every account's key setup is visible. Whether it still has its master key enabled, whether it assigned a separate signing key, whether it set up recovery signers, the whole configuration sits on-chain in the open.

We run a read-only crawler that reads the validated XRP Ledger and reports this posture on a public metrics page. It reads ledger state and holds no key, so the most it can do to an account is describe it.

Think of a building inspector who notes which doors are propped open while carrying no keys. Anyone can look up an account and read its posture straight from the ledger.

Because the ledger is transparent, how a network holds its keys is a measurable fact rather than a claim. A whole chain's custody posture can be surveyed without touching one key.
