$27 Million Hack Hits BigONE Exchange; Company Promises Complete User Compensation

BigONE Confirms $27M Hack, Ensures Full User Compensation After Hot Wallet Breach

Crypto exchange BigONE has confirmed a $27 million security breach following a hack of its hot wallet on July 16. The platform assured users that all affected funds will be fully reimbursed.

In its official statement, BigONE said it detected unusual transactions tied to a third-party vulnerability, which has since been addressed. No private keys were compromised, and the threat has been contained.

To aid the investigation, blockchain security firm SlowMist is assisting in tracing the stolen funds, which span multiple blockchains including Bitcoin, Ethereum, Solana, Tron, and BNB Chain.

Breakdown of Stolen Assets:

• 120 BTC
• 350 ETH
• 9.5 billion SHIB
• 7.1 million USDT (on multiple chains)
• 538,000 DOGE
• 1,800 SOL
• 1 WBTC
• 20,730 XIN
• 15.7 million CELR
• 25,487 UNI
• 16,071 LEO

BigONE stated that all losses will be covered using internal reserves in BTC, ETH, SOL, USDT, and XIN. For less liquid assets, the exchange may use short-term external borrowing to meet the compensation obligations.

While deposits and trading are expected to resume shortly, withdrawals will remain paused until additional security layers are deployed.

“We sincerely apologize for the inconvenience caused,” the exchange said. “We are committed to protecting our users and will maintain full transparency as we recover and strengthen operations.”

This breach adds to the mounting toll of crypto hacks in 2025, pushing total industry losses from exploits past $2.1 billion.
