HumidiFi halts trading after internal network incident

Solana decentralized exchange HumidiFi suspends trading on August 22, 2026, following an internal network security incident. While customer and third-party assets remain unaffected, the platform's proprietary automated market maker model leaves its own treasury exposed to the undisclosed losses. The disruption, HumidiFi's third major operational incident in eight months, triggers an 8.66% drop in its native WET token price to $0.07173, even as 24-hour trading volume surges by nearly 192%.
