# Grinex Crypto Exchange Shuts Down After $13.7M Breach, Blames Western Agencies Amid Exit Scam Allegations
What happened
In April 2026, Grinex, a mid-sized cryptocurrency exchange, suddenly shut down its platform following a massive security breach that resulted in the loss of approximately $13.7 million in user funds. The exchange publicly blamed Western intelligence agencies for orchestrating the hack, alleging targeted cyberattacks designed to destabilize its operations. Meanwhile, blockchain analytics firm Chainalysis flagged suspicious activity suggesting that Grinex may have been involved in an exit scam and linked to networks evading international sanctions.
The breach reportedly involved unauthorized access to Grinex’s hot wallets, enabling attackers to siphon off millions in various cryptocurrencies. The exchange’s abrupt closure left thousands of users unable to access their accounts or withdraw funds, sparking widespread concern and speculation in the crypto community.
