Indian Exchange Unocoin Says Wallet Backup Was Exploited Despite BitGo Account Freeze

Key takeaways

  • Unocoin said disputed transfers from one of its BitGo Ethereum addresses were signed and broadcast outside BitGo’s platform.
  • BitGo said the transactions used the user and backup keys held by Unocoin, and that its own systems were not breached.
  • The Indian exchange has suspended all services since Nov. 9 and has not yet said how much crypto, if any, was lost.

Indian crypto exchange Unocoin said a backup mechanism in its BitGo multisignature wallets “seems to be exploited,” after outgoing transfers were found despite a freeze on its BitGo account, according to its Nov. 13 update. The exchange has suspended all services since Nov. 9.

Unocoin first detected unauthorized activity on Nov. 6. It requested a freeze of its Fireblocks enterprise account at 11:24 UTC and its BitGo account at 11:29 UTC, and both providers confirmed the freezes. At that point, no loss of crypto had been identified, the company said.

After further unauthorized activity on Nov. 9, Unocoin suspended its services and later said its infrastructure had been compromised. On Nov. 12, it found outgoing transactions from an Ethereum address in its BitGo wallets that it used to fund ERC-20 tokens.

The exchange said it still cannot see all potentially unintended transactions, because its BitGo accounts remain frozen and the wallets use change addresses. It is investigating how the backup mechanism was accessed, any crypto losses and possible exposure of customer information.

BitGo Says Its Key Was Not Used

BitGo said the affected wallet used a two-of-three setup in which Unocoin held the user and backup keys and BitGo held the third. Its review found the Ethereum transactions were signed with Unocoin’s two keys and broadcast directly to the blockchain, BitGo said in a blog post.

“BitGo’s systems were not breached in connection with that transaction,” the company said in a statement to Cointelegraph. BitGo said transaction requests sent through its platform on Nov. 9 were blocked by the freeze, but a freeze does not lock funds on the blockchain or revoke compromised keys.

BitGo has advised Unocoin to move its remaining funds to new wallets with newly generated keys. In a Nov. 12 report, Unocoin said more than 90% of customer crypto was kept in cold storage, though it was still working out the full status of its holdings.

A Nov. 5 warning from India’s cybersecurity agency described an AI-assisted campaign targeting crypto exchanges and other financial firms, Cointelegraph reported, though no link to Unocoin has been established. Exchange breaches remain a major source of losses, with crypto hacks reaching $1.18 billion in the third quarter.

Unocoin said it is still working to complete its investigation and restore services, and will share significant updates once they are established. It has not given a date for reopening deposits and withdrawals.

Kraken Parent Payward Reports 66% Drop in Q3 Adjusted EBITDA to $60 Million

Kraken Parent Payward Reports 66% Drop in Q3 Adjusted EBITDA to $60 Million

Key takeaways

  • Payward’s third-quarter adjusted EBITDA fell 66% from a year earlier to $60 million, though it rose from $23 million in the second quarter.
  • Total platform margin, its new main revenue measure, fell 12% year over year to $487 million on $353 billion in transactions.
  • The company plans U.S. prediction markets, stock perpetual futures and a personal finance AI agent.

Kraken parent Payward reported $60 million in third-quarter adjusted EBITDA on Friday, down 66% from $178.6 million a year earlier but up from $23 million in the second quarter, according to The Block. Slower crypto trading weighed on fees.

The private company has replaced adjusted revenue with a measure it calls total platform margin, which also deducts staking rewards paid to customers. That figure fell 12% from a year earlier to $487 million, but rose 12% from $436 million in the second quarter.

Customers transacted $353 billion across Payward’s platforms in the quarter, down 30% year over year and up 22% from the prior quarter. Funded accounts reached 7.1 million at the end of September, up 37% from a year earlier, while billable accounts rose 74% to 1.5 million.

Payward nearly doubled its share of global crypto spot trading to 6.5% in September from 3.3% a year earlier, Cointelegraph reported. The number of derivatives contracts it charges a per-contract fee on rose 84% to 66 million, and margin from subscriptions and trader evaluations rose 59% to $125 million.

Less Reliance on Trading Fees

Income tied to client assets and access to products, data and services rose to 52% of the total, up from 46% a year earlier, CoinDesk reported. Margin from assets customers hold on its platforms, including staking services, rose 26% to $128 million, Cointelegraph said.

Payward said prediction markets for U.S. clients are among its next products, though it gave no launch date. It also plans stock perpetual futures through its own CFTC-regulated exchange, a test U.S. credit card, and a personal finance AI agent that would need customer approval before each trade, The Block said.

Its tokenized stock platform, xStocks, passed $1 billion in assets in October, and the company plans funds built around it. Payward has also expanded through acquisitions, including futures broker NinjaTrader, derivatives platform Bitnomial and stablecoin payments firm Reap, according to Cointelegraph.

Payward has also held talks with Wells Fargo about supplying liquidity for crypto trading, and separately discussed a financial-infrastructure partnership with BNY, CoinDesk previously reported, citing people familiar with the discussions. In November, a Payward-affiliated fund and its clients bought an undisclosed amount of AAVE tokens.

Other exchanges are under similar pressure. Coinbase’s third-quarter revenue fell 35% year over year, CoinDesk noted, while Gemini reported a 19% revenue drop and a 73% fall in trading volume this week.

The results could matter for a future listing. Payward confidentially filed for a U.S. IPO in November 2025 but paused the plan in March. By September, the earliest listing window it was considering was the second quarter of 2027, Cointelegraph reported.
