On July 21, 2026, a security breach on the Wanchain bridge linking Cardano and BNB Chain led to the theft of about 515 million NIGHT tokens worth $13 million. The exploit exploited a message encoding flaw, allowing attackers to amplify authorized transfers drastically. This caused a sharp selloff, dropping NIGHT token price over 30% to a record low. Wanchain has taken the bridge offline for investigation, while the Midnight Foundation confirmed that the core Midnight blockchain and Cardano network remain unaffected. The incident highlights ongoing risks in cross-chain bridges despite secure Layer-1 networks like Cardano.
Wanchain's Cardano-BNB Bridge was exploited due to a cryptographic flaw allowing attackers to reuse a legitimate signature to authorize fake withdrawals, resulting in the theft of 515 million NIGHT tokens worth $9 million. The vulnerability involved ...
Attackers exploited a signature reuse flaw in the Wanchain-operated Cardano–BNB Chain bridge, draining about 515 million NIGHT tokens worth $13 million. This caused the NIGHT token price to fall over 30% to a record low near $0.016. The breach was is...
The Midnight network's Wanchain Cardano-to-BNB cross-chain bridge was hacked, resulting in 515 million NIGHT tokens being stolen. The attacker sold a large portion, causing the wrapped NIGHT on BNB to become unbacked and the token price to plummet 32...
Wanchain's Cardano-to-BNB Chain bridge was exploited, resulting in the loss of approximately 515 million NIGHT tokens from its Cardano-side treasury. The Midnight Foundation confirmed the core Midnight network remains secure, attributing the incident...
