Open USD stablecoin launches on Ethereum, Solana, Base, and Tempo, backed by major firms and $1B in liquidity. The model ties partner rewards to supply and use, aiming for broad adoption.

Open USD (OUSD), a new US dollar-pegged stablecoin, has officially launched on four major blockchains: Ethereum, Solana, Base, and Tempo. The project is backed by leading financial and technology firms, including Mastercard, Visa, Stripe, Coinbase, and Shopify. It has secured over $1 billion in liquidity commitments from its five founding partners, each receiving equal initial equity stakes. OUSD introduces a model where future ownership and rewards are tied to partners' contributions in expanding the stablecoin’s supply and transaction volume. Issued by Stripe subsidiary Bridge, OUSD is backed by reserves managed by BlackRock, Lead Bank, and BNY, with monthly reserve attestations planned for public release. The partner network now includes over 200 companies, and OUSD is listed on major exchanges such as Coinbase, Kraken, and Uniswap. The initiative targets payments, banking, settlements, cross-border transfers, institutional trading, and lending, aiming to become a widely adopted stablecoin in a market currently led by USDT and USDC.
