Uniswap Newsletter Recaps OUSD, Stock Tokens, and API Updates

Uniswap's latest ecosystem newsletter recaps a week of launches and volume milestones. OUSD, Open Standard's payments stablecoin, is live with Uniswap as a key execution layer — millions in liquidity from day one, with a v4 hook that pays OUSD rewards to LPs in the works. Tokenized stocks did $20.9B in DEX volume over 30 days, 40.7% through Uniswap v4, while Uniswap has processed $70B in volume on Robinhood Chain and $300M+ in tokenized-equity volume on Base.

Also in the issue: PAXGy, Paxos's PAX Gold-based token, launches with Uniswap as its liquidity layer; Circle's cirBTC routes ~90% of its Arc trading through Uniswap; SMBC Nikko and Nethermind are building a Japan-facing venue on Uniswap v4 with compliance inside a hook; and three Uniswap API updates shipped — shared fees, instant calldata, and one-click bridge-and-swap.
