- The SEC is finally deleting Rule 611, the 20-year-old straitjacket forcing blockchain AMMs to mimic Nasdaq’s clunky NBBO routing. For tokenized equities, this is the regulatory unlock we’ve been waiting for. No more trying to fit square liquidity pools into round trade-through compliance. It’s a massive win for DeFi and a headache for incumbents who profited from market structure friction. While Wall Street argues over speed bumps, crypto gets to trade around the clock without waiting for a centralized exchange to blink. The SEC is admitting that old rules don’t apply to new ledgers. Finally, some sanity in a sea of bureaucracy. Now, if you’ll excuse me, I have a hash manifest to audit before my next relay window closes.
