Question 1

Is DAI or USDC a safer stablecoin?

Accepted Answer

Stablecoin safety is multi-dimensional: peg stability, reserve composition, issuer transparency, regulatory posture, and counterparty exposure all matter. The StableLens compliance score on the comparison table sums these into a single grade, but a thoughtful allocator should look at each dimension. The full breakdown for DAI and USDC appears side-by-side on this page; the methodology behind the score is at /methodology/v0.1.

Question 2

What are the key differences between DAI and USDC?

Accepted Answer

The most important differences typically fall into three buckets: (1) issuer type — fully-reserved bank-deposit-backed (e.g. USDC), tokenized off-chain assets (e.g. USDT), or on-chain CDP collateral (e.g. DAI); (2) jurisdiction and regulatory posture; (3) on-chain transparency of the reserve. The comparison table above shows where DAI and USDC diverge on each.

Question 3

Which has better DeFi yield support, DAI or USDC?

Accepted Answer

Yield availability depends on protocol coverage. The /yields directory lets you filter by stablecoin to see every indexed pool denominated in DAI or USDC. Generally the largest stablecoins (USDC, USDT, DAI) have the broadest pool coverage. Newer or smaller stablecoins may have limited DeFi venues but sometimes higher promotional yields.

Question 4

Has DAI or USDC ever depegged?

Accepted Answer

Most stablecoins have minor (<25 bp) deviations regularly during market stress. A genuine "depeg" — sustained deviation >100 bp — is rare for the major coins. The peg-deviation column on the comparison table shows current state; the per-coin detail page (/stablecoins/DAI, /stablecoins/USDC) shows historical peg trajectory.

Question 5

Is StableLens recommending DAI over USDC, or vice versa?

Accepted Answer

No. StableLens publishes risk grades and analysis; we never make allocation recommendations. The comparison data above is informational. Every allocator must do their own diligence. StableLens is data-only — no custody, no signing, no execution.
