The short answer
USDY scores higher on safety (88 vs 54), driven mainly by collateral quality and disclosure. USDY has deeper tracked liquidity ($2.21B), which is what determines whether you can exit at size. FRAX currently earns up to 8.60% — remember that any rate above the T-bill yield is payment for a risk.
If both are fiat-reserve tokens, note that holding both is not diversification: they share the same short-dated Treasury and banking exposure. Genuine diversification means mixing collateral structures.

Has FRAX or USDY ever depegged?
+
FRAX: no material depeg recorded in our incident set. USDY: no material depeg recorded in our incident set. Past peg behaviour under stress is the single best available proxy for how a token trades in the next crisis.
Which is better for large institutional size, FRAX or USDY?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. USDY shows deeper on-chain liquidity at $2.21B versus $91.54M. Combine that with the redemption channel — FRAX: market-only; USDY: gated — and size trades against the primary window rather than the order book where possible.
Can I earn yield on FRAX or USDY?
+
FRAX currently shows the higher rate at 8.60% via fraxlend · Ethereum, against 4.21% via navi-lending · Sui for USDY. Neither token pays interest by holding it in a wallet: the yield comes from lending, liquidity provision or a wrapped yield-bearing version, each with its own counterparty and contract risk.
Which chains support both FRAX and USDY?
+
Both are deployed on 4 shared networks, including Ethereum, Arbitrum, Osmosis, Solana. FRAX spans 14 chains in total and USDY spans 12. Bridged supply on a chain is not the same as natively issued supply, and it usually carries the bridge's risk rather than the issuer's.
What does it cost to switch from FRAX to USDY?
+
Budget three components: the current price spread of roughly 1368.0 bps, swap or venue fees, and slippage against available depth ($91.54M for FRAX, $2.21B for USDY). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is FRAX or USDY regulated?
+
FRAX is issued from Not documented with none; USDY is issued from BVI with monthly. Regulatory status varies by your own jurisdiction and by whether the token is offered under a specific stablecoin regime, so treat this as a starting point for diligence, not legal advice.
