Uniswap
OUSD, the dollar stablecoin from Open Standard, is live across the Uniswap Protocol, Web App, and API — and, per a Base announcement amplified by Uniswap, it is also live and liquid on Base, one of the four chains (with Ethereum, Solana, and Tempo) where the token launched natively. The token is supported by 200+ partners including Visa, Mastercard, Coinbase, and Stripe, with millions in liquidity from day one as Uniswap joins the network as a critical execution layer.
