In a startling turn of events, a severe cybersecurity breach struck SecondFi’s wallets, a key component of the Cardano network, during a short window between June 21 and June 23, 2026. A total of 374 wallets were compromised, resulting in a significant loss of 16 million ADA, valued at approximately $2.4 million. EMURGO, one of Cardano’s foundational entities, swiftly addressed the situation, announcing plans for complete reimbursement to affected users.
