"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 (80 vs 67), driven mainly by collateral quality and disclosure. DAI has deeper tracked liquidity ($305.57M), which is what determines whether you can exit at size. FRXUSD currently earns up to 5.47% — 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.

Has DAI or FRXUSD ever depegged?

Which is better for large institutional size, DAI or FRXUSD?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. DAI shows deeper on-chain liquidity at $305.57M versus $81.06M. Combine that with the redemption channel — DAI: direct; FRXUSD: market-only — and size trades against the primary window rather than the order book where possible.
Can I earn yield on DAI or FRXUSD?
+
FRXUSD currently shows the higher rate at 5.47% via aave-v4 · 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 FRXUSD?
+
Both are deployed on 9 shared networks, including Ethereum, Polygon, BSC, Arbitrum, OP Mainnet, Avalanche. DAI spans 31 chains in total and FRXUSD spans 17. 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 FRXUSD?
+
Budget three components: the current price spread of roughly 5.7 bps, swap or venue fees, and slippage against available depth ($305.57M for DAI, $81.06M for FRXUSD). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is DAI or FRXUSD regulated?
+
DAI is issued from Decentralised / Cayman foundation with onchain; FRXUSD 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.
