Midnight’s native token NIGHT has staged a notable recovery in the hours following a high-profile $10 million exploit on the Wanchain Cardano bridge.
After plunging as much as 50% intraday on July 21, 2026, the token climbed from session lows near $0.0158, posting gains of roughly 35%, according to CoinMarketCap data. The price action highlights the volatile but resilient nature of the Cardano ecosystem’s privacy-focused asset.
The Anatomy of the Exploit
Security firm BlockSec’s Phalcon monitor first flagged the incident on July 21. Attackers exploited a non-injective signed-message encoding flaw in the bridge’s TreasuryCheck validator. The vulnerability stemmed from raw concatenation of 14 variable-length redeemer fields without proper delimiters, enabling signature reuse.
In just eight minutes and four rapid transactions, the attacker drained approximately 515.2 million NIGHT tokens from the bridge treasury. The stolen assets, valued at roughly $10 million at prevailing prices, were funneled to a primary Cardano wallet before roughly 90% were liquidated through DEX swaps and DeFi protocols.
Wanchain quickly paused the affected Cardano-BNB route. Both the Wanchain team and Midnight Foundation emphasized that the core Midnight blockchain and Layer-1 remained uncompromised. The breach was confined to third-party bridging infrastructure. Midnight Foundation stated: “This incident does not reflect any vulnerability in the underlying Midnight blockchain.”
The root cause—a classic replay attack via ambiguous message construction—echoes past bridge failures across the industry. Wanchain had previously touted an eight-year exploit-free record, making the event particularly notable. On-chain analysis traced one legitimate BSC signature being reused to authorize massive unauthorized withdrawals on Cardano.
Market Reaction and the Rebound
NIGHT’s price reacted instantly to the sell pressure. The token dropped from intraday highs above $0.026 to a new all-time low near $0.01582, representing a peak-to-trough decline exceeding 40%. Daily trading volume exploded nearly 800% as panicked holders exited and opportunistic buyers entered.
By late July 21 into July 22, buyers defended key support levels. NIGHT recovered to approximately $0.0174, trimming some daily losses while maintaining higher lows on short timeframes. Social sentiment turned cautiously optimistic, with traders noting the token as a top gainer on the day and highlighting accumulation on the dip. Technical observers pointed to RSI recovering above 60 and price holding above moving averages as signs of building momentum.
The partial rebound reflects classic post-exploit dynamics: initial fear-driven liquidation followed by bargain hunting once the scope was clarified as bridge-specific rather than protocol-wide. However, uncertainty lingers over the roughly 200 million unsold NIGHT still potentially in attacker-controlled wallets.
Outlook: Recovery Prospects and Lingering Risks
The NIGHT pump demonstrates short-term market resilience but also underscores ongoing bridge security challenges in cross-chain DeFi. Midnight’s privacy narrative and Cardano ties continue to attract long-term interest, yet repeated infrastructure incidents could weigh on confidence.
Wanchain and Midnight teams have promised full investigations and updates. Key factors for sustained recovery include transparent post-mortems, code patches, potential asset tracing or freezes, and resumption of secure bridging. Broader market sentiment, Bitcoin’s performance, and adoption metrics for Midnight (such as holder growth and ecosystem integrations) will also influence price action.
At the time of publishing, NIGHT trades with elevated volatility. While the rebound offers relief, participants should monitor resistance levels near $0.023 and support around $0.015–0.016.
The incident serves as a reminder that while Layer-1 projects like Midnight may remain secure, reliance on third-party bridges introduces external risks that can rapidly impact token prices.
