What are the most transparent stablecoins?
Transparency is attestation frequency, disclosure depth and a regulated issuer structure — captured in the collateral and issuer-legal components of the safety score. Ranked by the average of those two subscores.

Frequently asked
+ − Which stablecoin publishes attestations most often?
The table above ranks by our collateral-verification and issuer-legal subscores, which reward daily or monthly attestations from a named third party over quarterly or absent reporting. Check each asset page for the actual attestation cadence.
+ − What counts as a transparent reserve report?
A named attestor, a breakdown of instrument types (not just 'cash and equivalents'), and a cadence of monthly or better. Point-in-time attestations without a named auditor score lower than audited reports.
+ − Does transparency guarantee safety?
No — it removes one source of uncertainty (what backs the token) but says nothing about peg stability under stress or exit liquidity. Use the full safety score, not disclosure alone, to size a position.
