anchored·3tpHKU…TzaqSummary
DEXX is a Solana-based on-chain memecoin trading terminal that suffered a catastrophic private key compromise on November 16, 2024, resulting in approximately $30 million in user losses across more than 8,600 wallets. Despite marketing itself as non-custodial, DEXX stored user private keys in plaintext on its own servers — a centralization risk that CertiK had flagged as unresolved prior to the breach. A partial compensation initiative led by LBank was announced in early 2025, but full recovery of stolen funds remains unlikely as the attacker laundered substantial ETH through Tornado Cash.
