BitGo says Unocoin outflow was signed by Unocoin’s own keys, third key unused

The significance here is jurisdictional: the loss sits with Unocoin's own key custody rather than the shared infrastructure provider, which narrows the blast radius to a single client and removes a platform-wide failure narrative. For other BitGo clients on similar 2-of-3 setups, the reassurance is structural — the third key was never invoked — but it also highlights that self-custody arrangements concentrate operational risk at the key-holder. What remains open is how the two Unocoin-held keys were compromised, and whether the suspension reveals anything about internal controls that other self-custody operators share.
