Charles Hoskinson, founder of Cardano and key developer behind the privacy-focused blockchain project Midnight, emphasized the need to move past outdated bridge technology in the cryptocurrency industry after a recent exploit on the Wanchain bridge led to a significant theft and price crash for the NIGHT token.
Bridge exploit sinks NIGHT price
On Monday, an exploit targeting a legacy Wanchain bridge resulted in the theft of 290 million NIGHT tokens. The tokens were quickly sold across the Binance-Cardano corridor, pushing the price of NIGHT down approximately 43% to a historic low before partial recovery.
Within 24 hours, NIGHT recovered roughly 19%, rebounding to trade around $0.022. Hoskinson, responding to coverage that primarily highlighted the crash, drew attention to the market’s recovery and stated the rebound was being overlooked by some observers.
Wanchain, a company dedicated to developing decentralized cross-chain bridge technology, was responsible for the bridge infrastructure involved in the incident.

“All software is under this enormous assault,” Hoskinson said, pointing to a rise in Linux kernel vulnerabilities and attributing this trend to AI-powered exploit discovery. He noted that, while robust systems may reduce risk, constant exposure still leaves them vulnerable over time.
Security challenges in cross-chain bridges
Bridge hacks remain a persistent and damaging threat within the crypto sector. In recent years, attacks on bridges like Ronin, Wormhole, and Nomad have collectively cost the industry over $1.5 billion.
These exploits typically target the smart contracts and multisignature (multisig) setups that facilitate token movements between blockchains. Once compromised, large sums can be drained rapidly due to limited underlying security.
| Bridge | Year | Loss |
|---|---|---|
| Ronin | 2022 | $620 million |
| Wormhole | 2022 | $320 million |
| Nomad | 2022 | $190 million |
| Wanchain (NIGHT) | 2024 | 290 million NIGHT |
Hoskinson advocated for zero-knowledge systems such as Midnight, explaining that these platforms can eliminate the need for trust in bridge operators and multisigs by substituting cryptographic proofs for human intervention.
The case for zero-knowledge systems
Hoskinson suggested that attackers are increasingly using AI tools to identify vulnerabilities across all types of software, not just within the crypto sector. He reiterated that, while improved architecture can help, legacy solutions often fail to fully protect projects from sophisticated attacks.
Zero-knowledge proof systems, like those used in Midnight, establish transaction validity without revealing underlying data. Hoskinson described this approach as the next step in advancing blockchain security and building greater resilience into cross-chain solutions.

The incident has highlighted the ongoing debate about the best ways to secure rapidly evolving digital assets and infrastructure, especially as both attackers and defenders turn to advanced technologies.
