Wanchain bridge exploit drains 515M NIGHT tokens, causing 30% price drop in Midnight's native token.

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 solely to the third-party bridge infrastructure operated by Wanchain. The exploit caused a sharp 30% drop in NIGHT's price as investigations pointed to a possible signature reuse vulnerability in the TreasuryCheck validator used by the bridge. The incident highlights ongoing security risks in cross-chain bridges, with further investigation underway to fully understand the attack and prevent future breaches.
