Harmony ONE crashes 40% after attacker mints 4 billion tokens; Uniswap slides 9% as SEC tightens crypto rules

Two stories dominated today. The first: an attacker exploited a vulnerability in Harmony's smart contracts to mint approximately 4 billion ONE tokens — roughly a quarter of the asset's entire supply — out of thin air. The token crashed around 40% on the news. The mechanics here matter: minting that volume of new tokens instantly dilutes every existing holder, and the attacker can sell those tokens into the market, compounding the price collapse. It's a reminder that smart contract security remains one of the sharpest risks in DeFi (decentralized finance, where code governs transactions without a central intermediary). The second story is regulatory. The SEC appears to be formalizing what analysts at TD Cowen are calling 'Reg Crypto' — a structured framework for how crypto assets get classified and regulated. A token safe harbor, which would give projects a defined window to achieve compliance before facing enforcement, is reportedly on the table. That sounds constructive in the long run, but the near-term effect was the opposite: DeFi tokens sold off as traders priced in the possibility of tighter rules. Uniswap, the largest decentralized exchange by volume, fell 9% — the sharpest drop in the top tracked universe today. Overlaying both stories is a market already on edge. The Fear & Greed index sits at 27, firmly in fear territory, and traders in the Bitcoin and Ethereum options markets are positioning cautiously ahead of a U.S. CPI (consumer price index, the main inflation gauge) release. A hotter-than-expected print could push the Fed toward keeping rates higher for longer, which historically weighs on risk assets including crypto. A cooler print could provide relief. The market is waiting.

• –An XRP bridge was drained of $200,000 after a software flaw caused the system to treat fake deposits as real ones — a separate security incident from the Harmony exploit, adding to a difficult day for DeFi infrastructure.
• –Bitwise Asset Management cut 14% of its staff today, one of the more visible signs that the prolonged market downturn — with Fear & Greed at 27 — is translating into real cost-cutting at established crypto firms.
• –The SEC's emerging 'Reg Crypto' framework, flagged by TD Cowen analysts as potentially pivotal, could reshape compliance requirements across the industry; a formal proposal has not yet been published.
