"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

DAI scores higher on safety (81 vs 54), driven mainly by collateral quality and disclosure. DAI has deeper tracked liquidity ($318.75M), which is what determines whether you can exit at size. DAI currently earns up to 4.79% — 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 USDJ?

Capital preservation over everything else.

For park cash safely, DAI is the better fit over USDJ.

  • Safety score 81 vs 54, with collateral rated 84/100.
  • Current peg deviation -0.010% against 0.000% for USDJ.
  • DAI has 2 recorded depeg event(s) — read them before sizing up.

Concentrating in one issuer is a single point of failure regardless of score. Split across collateral structures.

A round trip between DAI and USDJ costs roughly the market spread plus venue fees. At 1.0 bps of price gap, swapping $1M implies about $98.97 of price impact before fees — usually only worth it if the peg gap or yield spread is durable, not intraday noise.

DAI vs USDJ: frequently asked questions

Is DAI or USDJ safer?

+

On our composite safety score DAI rates 81/100 versus 54/100 for USDJ. The score weighs collateral quality (crypto-overcollateralized 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 DAI and USDJ?

+

Dai is issued by Sky (formerly MakerDAO) (Decentralised / Cayman foundation), backed by crypto-overcollateralized, with redemption terms: direct. USDJ is issued by Undisclosed (Not documented), backed by crypto-backed, with redemption terms: market-only. Attestation coverage is "onchain" for DAI and "none" for USDJ.

Which has the bigger market cap, DAI or USDJ?

+

DAI is larger at $4.77B in circulating supply, against $539.0K for the other. Over the last 7 days supply moved −0.31% for DAI and −0.04% for USDJ.

Are DAI and USDJ trading at $1.00 right now?

+

DAI trades at $0.9999 (−0.010% off peg) and USDJ at $1.0000 (0.000% off peg). The gap between the two is about 1.0 basis points, which is the cost you pay when rotating size between them before fees.

Has DAI or USDJ ever depegged?

+

DAI: worst recorded deviation −7.4%. USDJ: 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 USDJ?

+

For block size the constraint is exit liquidity and primary redemption, not headline supply. DAI shows deeper on-chain liquidity at $318.75M versus $0.00. Combine that with the redemption channel — DAI: direct; USDJ: market-only — and size trades against the primary window rather than the order book where possible.

Can I earn yield on DAI or USDJ?

+

DAI currently shows the higher rate at 4.79% via aave-v3 · Polygon, against no tracked rate for USDJ. 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 USDJ?

+

They currently share no common network in our data: DAI is deployed on 31 chain(s) and USDJ on 1. Moving between them requires a bridge or a centralised venue.

What does it cost to switch from DAI to USDJ?

+

Budget three components: the current price spread of roughly 1.0 bps, swap or venue fees, and slippage against available depth ($318.75M for DAI, $0.00 for USDJ). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.

Is DAI or USDJ regulated?

+

DAI is issued from Decentralised / Cayman foundation with onchain; USDJ 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.
