Question 1

Is FDUSD or YLDS 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 FDUSD and YLDS 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 FDUSD and YLDS?

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 FDUSD and YLDS diverge on each.

Question 3

Which has better DeFi yield support, FDUSD or YLDS?

Accepted Answer

Yield availability depends on protocol coverage. The /yields directory lets you filter by stablecoin to see every indexed pool denominated in FDUSD or YLDS. 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 FDUSD or YLDS 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/FDUSD, /stablecoins/YLDS) shows historical peg trajectory.

Question 5

Is StableLens recommending FDUSD over YLDS, 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.
