"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
RLUSD scores higher on safety (91 vs 85), driven mainly by collateral quality and disclosure. DAI has deeper tracked liquidity ($1.11B), which is what determines whether you can exit at size. RLUSD currently earns up to 4.99% — 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: DAI or RLUSD?
Capital preservation over everything else.
For park cash safely, RLUSD is the better fit over DAI.
- Safety score 91 vs 85, with collateral rated 95/100.
- Current peg deviation 0.030% against -0.009% for DAI.
- No material depeg recorded for RLUSD in our incident log.
Concentrating in one issuer is a single point of failure regardless of score. Split across collateral structures.
Key risks, side by side
DAI
- Collateral volatility: a fast drawdown in backing assets can force liquidations.

- Attestation cadence: onchain.
- Yield venue risk: 4.71% is earned outside the token itself.
- Chain concentration: 86% of supply sits on Ethereum.
RLUSD
- Issuer and banking risk: reserves sit with Ripple under United States (NYDFS) rules.

A round trip between DAI and RLUSD costs roughly the market spread plus venue fees. At 3.9 bps of price gap, swapping $1M implies about $390.20 of price impact before fees — usually only worth it if the peg gap or yield spread is durable, not intraday noise.
Historical context
Track record is the part of a stablecoin you cannot model — it has to be observed. Here is how DAI and RLUSD have actually behaved since launch, including every stress event we have on record.

Chain coverage
DAI is live on 35 chains, RLUSD on 2. 1 chains carry both, so bridging is only unavoidable for the 35 networks where just one of them is deployed.

DAI vs RLUSD: frequently asked questions
Is DAI or RLUSD safer?
+
On our composite safety score RLUSD rates 91/100 versus 85/100 for DAI. The score weighs collateral quality (treasuries vs crypto-overcollateralized), 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 DAI and RLUSD?
+
Dai is issued by Sky (formerly MakerDAO) (Decentralised / Cayman foundation), backed by crypto-overcollateralized, with redemption terms: direct. Ripple USD is issued by Ripple (United States (NYDFS)), backed by treasuries, with redemption terms: direct. Attestation coverage is "onchain" for DAI and "monthly" for RLUSD.
Which has the bigger market cap, DAI or RLUSD?
+
DAI is larger at $4.77B in circulating supply, against $1.76B for the other. Over the last 7 days supply moved −0.54% for DAI and +13.28% for RLUSD.
Are DAI and RLUSD trading at $1.00 right now?
+
DAI trades at $0.9999 (−0.009% off peg) and RLUSD at $1.0003 (+0.030% off peg). The gap between the two is about 3.9 basis points, which is the cost you pay when rotating size between them before fees.
Has DAI or RLUSD ever depegged?
+
DAI: worst recorded deviation −7.4%. RLUSD: 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, DAI or RLUSD?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. DAI shows deeper on-chain liquidity at $1.11B versus $505.74M. Combine that with the redemption channel — DAI: direct; RLUSD: direct — and size trades against the primary window rather than the order book where possible.
Can I earn yield on DAI or RLUSD?
+
RLUSD currently shows the higher rate at 4.99% via aave-v3 · Ethereum, against 4.71% via flux-finance · Ethereum for DAI. 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 DAI and RLUSD?
+
Both are deployed on 1 shared network, including Ethereum. DAI spans 35 chains in total and RLUSD spans 2. 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 DAI to RLUSD?
+
Budget three components: the current price spread of roughly 3.9 bps, swap or venue fees, and slippage against available depth ($1.11B for DAI, $505.74M for RLUSD). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is DAI or RLUSD regulated?
+
DAI is issued from Decentralised / Cayman foundation with onchain; RLUSD is issued from United States (NYDFS) 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.
