Frequently Asked Questions

Which is bigger, USDf or U?

Is USDf safer than U?
Neither is inherently safer. Safety turns on reserve composition, issuer transparency, redemption rights and regulatory oversight — none of which this page audits. Both use a crypto-backed model, so the difference sits in the issuer and the reserves rather than the design. Read each issuer's most recent reserve attestation before choosing.
Can I convert between USDf and U?
Yes. USDf and U 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.
Should I choose USDf or U?
The right choice depends on your use case. Consider: which chain do you need? USDf is available on 2 chains and U on 4. 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.
