Unocoin Says BitGo Address Sent Untraceable Transactions

The admission that an exchange cannot trace outbound flows from a custody provider's address shifts the problem from a single security incident to a visibility gap in the custody chain — a more uncomfortable issue for an industry that sells custody on the promise of auditable movement. The affected parties extend beyond Unocoin's own users to anyone relying on BitGo-attested address controls as a risk assumption. With the exchange still suspended and the full extent unknown, the open question is whether BitGo can reconstruct and attribute those transactions, and what that answer implies for how much of custodial activity is genuinely observable.
