Stablecoin

Aqua (also known as AquaBot) was a Solana-based Telegram trading bot that conducted a presale in September 2025, raising approximately 21,770 SOL ($4.65 million) from retail investors before executing an apparent exit scam. On-chain investigator ZachXBT flagged the project after presale funds were split into four tranches, routed through intermediary wallets, and sent to instant exchanges hours before the scheduled token generation event. The project had secured endorsements from multiple established Solana ecosystem participants — including Meteora, Helius, Dialect, SYMMIO — and had received a near-perfect audit score from QuillAudits just days before the alleged rug pull.

Tapioca DAO is an omnichain DeFi money market built on LayerZero, offering a CDP stablecoin (USDO) and isolated lending markets (Singularity/Big Bang) across Arbitrum and BNB Chain. On October 18, 2024, the protocol suffered a critical security breach when a team member was targeted by a social engineering attack attributed to North Korea's Contagious Interview campaign, resulting in private key compromise, drainage of TAP token vesting contracts, and the minting of 5 quintillion USDO. Approximately $4.4–4.7 million was stolen before a partial counter-exploit recovered roughly 996 ETH (~$2.7 million), leaving the protocol treasury down approximately 45% and the TAP token price collapsed over 95%.
