The short answer
USYC scores higher on safety (74 vs 69), driven mainly by collateral quality and disclosure. USYC has deeper tracked liquidity ($2.98B), which is what determines whether you can exit at size. USDD currently earns up to 3.97% — 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.

Which chains support both USDD and USYC?
+

+
Budget three components: the current price spread of roughly 1190.6 bps, swap or venue fees, and slippage against available depth ($432.82M for USDD, $2.98B for USYC). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
