A Solana-based decentralized exchange suspended trading on August 22, 2026, after an internal network incident affected its systems and part of its own operating funds. The platform was identified as Humidifi in initial reports by SolanaFloor and as WET in subsequent coverage by BitcoinWorld. The teams stated that losses were limited to their own capital, and no customer or third-party assets were compromised.
The exchange operates a proprietary automated market maker model that supplies liquidity with its own funds rather than relying on external liquidity providers. It had gained significant traction in the Solana ecosystem, with daily trading volume once surpassing $1 billion. The incident reportedly affected part of its internal infrastructure and was detected during routine monitoring. The team has launched an investigation to determine the scope of the event, but has not yet clarified whether the cause was an external attack, a smart contract vulnerability, or an internal error.
No specific timeline has been provided for resuming trading. The decision to halt operations was framed as a precautionary measure to prevent further losses and protect user funds. The event highlights ongoing vulnerabilities in decentralized finance, particularly around smart contract security, oracle failures, and internal operational risk. For traders and liquidity providers, the suspension may temporarily reduce liquidity in Solana-based DeFi and affect confidence in similar protocols. Market participants are advised to monitor official channels for updates.
