Is USDT safer than USDG?
Neither is inherently safer. Safety turns on reserve composition, issuer transparency, redemption rights and regulatory oversight — none of which this page audits.

The right choice depends on your use case. Consider: which chain do you need? USDT is available on 130 chains and USDG on 6. 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.
