What Unocoin Has Told Users
In a November 9 post on its blog and on X, the Bengaluru-based exchange said it had disabled user logins as a precaution. Its technical team is looking into the incident and working on fixes.
“We want to clearly communicate that no crypto funds have been lost in this incident,” the company wrote. It added that users will not be able to access their accounts until the investigation and remediation are done.
Unocoin apologized for the disruption and said it would share its findings later. It did not give a date.
The exchange has not said how the attackers got in. It also has not said whether personal data, such as ID documents or contact details, was exposed.
By November 12, Unocoin’s website was showing a Cloudflare 504 Gateway Time-out error. This means the site’s main server was not responding in time, while Cloudflare’s network was working normally.
Empty Wallets on Blockchain Records
On November 12, the blockchain tracking account Onchain Lens posted data from Arkham Intelligence. A rkham links wallet addresses to known groups such as exchanges and funds.
Arkham lists about 81,000 addresses tied to Unocoin. Their combined value is shown as $0, with the message “No assets found.”
The data does not prove funds were stolen. A server breach alone does not move coins, since funds only leave a wallet when someone signs a transaction with its private keys.
The empty balances could mean assets were moved out by an attacker. They could also mean Unocoin moved its reserves to new wallets as a safety step.
Another option is a labeling gap. If funds sit in new addresses that Arkham has not yet tagged, the page would show $0 even if the exchange still controls the money.
No independent investigator has linked the zero balances to the breach. Unocoin has not responded publicly to the Arkham data, and crypto.news said it had not received a reply to its questions.
Unocoin was founded in 2013 and is one of India’s longest-running crypto platforms. In August 2017, it blocked website access after users reported unauthorized Bitcoin transfers from their accounts.
Other Indian exchanges have also faced attacks. WazirX lost about $235 million in July 2024, and CoinDCX lost about $44 million in July 2025.
In October, CoinDCX disclosed a loss of 15.99 million USDT from old deposit wallets compromised in its 2025 breach. The exchange said it covered the loss without touching customer balances.
As of November 12, Unocoin had issued no new update since its first statement. Users remain locked out for a fourth day, and the company’s blog and X account are its only confirmed update channels.
