The Cardano blockchain experienced a split into two chains on November 22, triggered by a malformed staking transaction that exploited a software vulnerability. This transaction was validated by the latest node version but rejected by older software, resulting in a network fork. Intersect, a Cardano governance body, assured that no user funds were compromised and most retail wallets remained unaffected. Following the incident, Cardano's ADA token saw a price decline of over 6%.
