## Recent evidence

- [confirms] DeFi Exploit Drains Roughly $578,000 as Seoul Police Break Up $19 Million Staking Fraud (2026-07-31): A reward-recycling manipulation drained roughly $578,000 from a BNB Chain protocol while Seoul police arrested three people over a $19M fake-XRP staking platform. Another mid-size on-chain exploit in a steady series keeps monthly DeFi losses elevated, an incremental confirmation of the thesis.
- [confirms] DeFi Self-Dealing Exploits Drain Reward Vaults on Ethereum and BNB Chain (2026-07-30): Proof-of-concept reconstructions detail a ~301.7 ETH reward-vault drain on Ethereum and a 605,000 USDT reward-on-transfer attack on BNB Chain, both caused by flawed incentive logic rather than stolen keys. It sustains the elevated-DeFi-loss thesis while widening the failure mode from proof/mint bugs to broken reward-vault economics.
