Both USDG and USD0 track USD, but they differ in backing and issuer. USDG is backed by cash reserves (paxos) while USD0 is backed by tokenized us treasuries (usual). As of today, USDG ranks #7 and USD0 ranks #20 among tracked stablecoins.
USDG is larger, with $3.26B in circulation vs $552.9M for USD0. That's roughly 5.9× the size.
Neither USDG nor USD0 is inherently "safer" — safety depends on the specific backing composition, issuer transparency, redemption rights, and regulatory oversight. USDG uses fiat-backed backing model; USD0 uses fiat-backed. Users should read each issuer's most recent reserve attestation before choosing.
Yes. USDG and USD0 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? USDG is available on 6 chains and USD0 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.
