Onramp CEO Urges Three Checks for Corporate Bitcoin Custody

Onramp CEO Michael Tanguma is urging companies that hold Bitcoin (BTC) to examine three custody questions: who controls the assets, who approves transfers and whether holdings can be checked independently. Tanguma argues that an account balance does not answer all three. Proof-of-reserves snapshots can show assets at a point in time, but they do not explain who can authorize a future withdrawal. Dividing signing authority among institutions addresses control over transfers; a corporate client also needs a way to verify its own holdings. Tanguma advocates a multi-signature custody model in which independent institutions create and hold separate keys.
