Yes. OUSD and GHO both trade on major centralized and decentralized exchanges. Since both track USD, the exchange rate is typically very close to 1:1. Direct swap protocols on Ethereum, Solana, and other chains offer the tightest spreads.
The right choice depends on your use case. Consider: which chain do you need? OUSD is available on 4 chains and GHO on 2. What backing do you prefer? What's your integration surface (exchanges, DeFi protocols, payment providers)? Both have deep liquidity, so market cap alone shouldn't decide it.
