Open USD stablecoin rolls out on Solana and joins Polygon network

A consortium of more than 140 companies, including Visa, Mastercard and Coinbase, has launched the Open USD (OUSD) stablecoin. The token is designed to return nearly all reserve‑yield to holders, unlike many incumbent stablecoins that keep earnings for the issuer. OUSD’s first trading venue will be the Solana blockchain, positioning it as a direct competitor to USDC.

Polygon Foundation CEO Sandeep Nailwal announced that OUSD will also be integrated with the Polygon network, adding the consortium‑backed stablecoin to a blockchain that already processes trillions in stablecoin volume. The integration aims to broaden OUSD’s liquidity and use cases across multiple chains while leveraging Polygon’s low‑cost, high‑speed infrastructure.
