Unocoin Cannot Fully Trace Transfers From Frozen BitGo Accounts

By Nathan Brooks

Unocoin said it suspended all services on Nov. 9 after detecting further unauthorized activity. The Indian crypto exchange's BitGo enterprise accounts remain frozen, and the company cannot log in, limiting its ability to reconstruct transfers from an Ethereum address in the setup.

Unocoin said it detected transfers from that Ethereum address but cannot fully assess potentially unintended activity across its BitGo wallets after losing account access. The exchange has requested transaction-level records for the individual transactions, seeking detail that its current account access does not provide.

The update disclosed no transaction count, amount, destination address or cause. That leaves the scale of the incident undefined: readers cannot calculate an aggregate value, determine how many transfers occurred or identify a destination from the information provided.

Why change addresses matter

BitGo's use of change addresses is the technical constraint Unocoin cited. A change address receives the leftover funds remaining after a transaction. Unocoin said BitGo applies that address pattern across much of its wallet architecture, which makes it harder to connect the movement of funds to a clear transaction sequence across Unocoin's wallets.

This creates an evidentiary gap for anyone trying to establish the full path and status of the transfers. Address visibility can identify a movement, but Unocoin says it cannot use account access and the change-address structure together to assess potentially unintended activity across the wallets. Its request for individual transaction records addresses that gap.

For investigators and market participants, the immediate issue is evidentiary rather than merely operational. An address-level record can establish that a transfer occurred, while account-level records are needed to test its authorization and reconcile it across wallets. Unocoin's inability to combine those views is why it requested transaction-level records.

What does this change for users and counterparties?

For users and counterparties, the practical change is that Unocoin cannot yet present a complete account of the transfers associated with its BitGo setup. The exchange had already disclosed unusual transfers tied to BitGo before the Nov. 9 suspension, and its investigation found that its infrastructure had been compromised.

BitGo has opened a separate investigation into how the transactions occurred. The update did not disclose any findings from that inquiry.

Unocoin's statement also requires careful reading. It labels activity across the wallets as "potentially unintended," while describing the further activity detected before the service suspension as "unauthorized." The update does not establish that every transfer in the BitGo arrangement was illegitimate, nor does it identify a responsible actor, a mechanism or a final cause.

The freeze compounds the disclosure problem by preventing the exchange from logging in. It also means the current account record cannot substitute for the records requested from BitGo. The update does not say which party imposed the freeze, how long it will last or what restoration would require, so no firm reopening timetable can be inferred.

Nor does the update connect the freeze to a regulator, court process or law-enforcement action. The verified facts are corporate and technical: Unocoin's services are off, its BitGo enterprise accounts remain inaccessible, transaction-level records have been requested, and BitGo is investigating execution.

Any assessment of aggregate exposure would exceed the disclosed record because Unocoin has supplied neither a transaction count nor a monetary amount. It has also omitted any destination address and any final explanation of cause, preventing a complete account of affected wallets.

No deadline has been disclosed; the next material checkpoint is delivery of the requested transaction-level records and any findings from BitGo's investigation, and until then the count, value, destinations and cause remain unresolved.
