At last. The SEC closed its investigation into @Uniswap with no enforcement action. This investigation cost Uniswap tremendous time, tens of millions, and held back the promise of DeFi for years. This is a win for DeFi, and a step toward more accessible, transparent and fair

We’ve always been proud to operate in NYC, in broad daylight. Glad to see NY’s @SenGillibrand and @SenSchumer support constructive legislation on SAB 121 last week, and excited for a bipartisan vote in the House this week on FIT 21 to keep users safe and the U.S. innovating.

Crypto will continue to get more powerful due to demographic tailwinds. Ownership is ~30% for ages 18-45 and only 5% over 65. Politicians for/against follows roughly the same trend. As time goes on, today's young supporters grow as a % of global wealth and governance power.

Marvin and I first bonded over the future of an open internet in 2016. I was trying to change the financial system from the inside, with mixed success. In 2020, Marvin urged me to join him at @Uniswap, a project that he believed could make an actual dent in disrupting markets.
