The short answer
USDG scores higher on safety (93 vs 72), driven mainly by collateral quality and disclosure. U has deeper tracked liquidity ($38.63B), which is what determines whether you can exit at size. U currently earns up to 8.00% — 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 one fits your goal: U or USDG?
Capital preservation over everything else.
For park cash safely, USDG is the better fit over U.
- Safety score 93 vs 72, with collateral rated 95/100.
- Current peg deviation -0.004% against -0.067% for U.
- No material depeg recorded for USDG in our incident log.
Concentrating in one issuer is a single point of failure regardless of score. Split across collateral structures.

A round trip between U and USDG costs roughly the market spread plus venue fees. At 6.3 bps of price gap, swapping $1M implies about $633.80 of price impact before fees — usually only worth it if the peg gap or yield spread is durable, not intraday noise.
Historical context

U vs USDG: frequently asked questions
Is U or USDG safer?
+
On our composite safety score USDG rates 93/100 versus 72/100 for U. The score weighs collateral quality (treasuries vs crypto-backed), redemption rights, attestation quality, peg history and liquidity depth. A higher score is not a guarantee: both remain issuer-credit and smart-contract exposures, not insured bank deposits.
What is the difference between U and USDG?
+
United Stables is issued by Undisclosed (Not documented), backed by crypto-backed, with redemption terms: market-only. Global Dollar is issued by Paxos Digital Singapore (Singapore (MAS)), backed by treasuries, with redemption terms: direct. Attestation coverage is "none" for U and "monthly" for USDG.
Which has the bigger market cap, U or USDG?
+
USDG is larger at $3.09B in circulating supply, against $1.56B for the other. Over the last 7 days supply moved +6.32% for U and −3.15% for USDG.
Are U and USDG trading at $1.00 right now?
+
U trades at $0.9993 (−0.067% off peg) and USDG at $1.0000 (−0.004% off peg). The gap between the two is about 6.3 basis points, which is the cost you pay when rotating size between them before fees.
Has U or USDG ever depegged?
+
U: no material depeg recorded in our incident set. USDG: 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, U or USDG?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. U shows deeper on-chain liquidity at $38.63B versus $789.34M. Combine that with the redemption channel — U: market-only; USDG: direct — and size trades against the primary window rather than the order book where possible.
Can I earn yield on U or USDG?
+
U currently shows the higher rate at 8.00% via bitway-earn · BSC, against 6.74% via kamino-lend · Solana for USDG. 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 U and USDG?
+
Both are deployed on 2 shared networks, including Ethereum, Robinhood Chain. U spans 4 chains in total and USDG spans 6. 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 U to USDG?
+
Budget three components: the current price spread of roughly 6.3 bps, swap or venue fees, and slippage against available depth ($38.63B for U, $789.34M for USDG). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is U or USDG regulated?
+
U is issued from Not documented with none; USDG is issued from Singapore (MAS) 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.
