Why reserve transparency matters
A stablecoin’s peg is only as strong as what backs it — and only as trustworthy as the issuer’s willingness to prove it. A genuine attestation shows the reserve composition (cash, Treasuries, commercial paper, other), confirms independent audit, and is published on a regular cadence.
What to watch
- No public attestation at all, or one that’s months out of date.
- Reserves partly held in the issuer’s own token rather than external assets.
- Crypto House links each issuer’s own transparency page directly — verify the primary source, don’t just trust the label.
