"Matters" is our weighting of how much each dimension typically drives a real allocation decision. Sort any column to re-rank the tradeoffs by what matters to you.
The short answer
USDB scores higher on safety (56 vs 39), driven mainly by collateral quality and disclosure. USDB has deeper tracked liquidity ($3.02M), which is what determines whether you can exit at size.
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 USDB or USDZ ever depegged?

Which is better for large institutional size, USDB or USDZ?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. USDB shows deeper on-chain liquidity at $3.02M versus $0.00. Combine that with the redemption channel — USDB: market-only; USDZ: market-only — and size trades against the primary window rather than the order book where possible.
Can I earn yield on USDB or USDZ?
+
Neither USDB nor USDZ currently has a tracked yield venue in our dataset. Holding either in a wallet pays nothing; any advertised rate comes from lending or liquidity provision on top, with its own risk.
Which chains support both USDB and USDZ?
+
Both are deployed on 1 shared network, including Blast. USDB spans 1 chains in total and USDZ spans 4. 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 USDB to USDZ?
+
Budget three components: the current price spread of roughly 481.2 bps, swap or venue fees, and slippage against available depth ($3.02M for USDB, $0.00 for USDZ). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is USDB or USDZ regulated?
+
USDB is issued from Not documented with none; USDZ is issued from Not documented with none. 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.
