Methodology

Every number on this site should be checkable. Here is exactly how the safety score is built, where the market data comes from, and where our judgment enters.

The safety score

A 0–100 composite of five weighted factors. Market inputs refresh continuously; issuer, legal and collateral inputs are maintained by hand and reviewed when disclosures change. The score is an opinion, not a rating in any regulatory sense.

  • Collateral quality & transparency

    30%

    What actually backs the token and how often it is verified. Treasury-backed with daily or on-chain proof scores highest; unattested reserves score lowest.

  • Peg stability

    25%

    Live deviation from $1.00 plus the worst historical depeg on record. A single deep depeg keeps weighing on the score.

  • Liquidity depth

    20%

    Tracked on-chain pool liquidity in absolute dollars and as a share of circulating supply — how much can exit before the price moves.

  • Issuer & legal structure

    15%

    Regulatory status of the issuer and whether holders have a direct redemption right or only a secondary market exit.

  • Track record

    10%

    Years in production, minus documented incidents.

Yield rating and risk-adjusted APY

Yields are scored by a separate model: a 0–100 durability rating built from pool depth, base-versus-incentive split, 30-day rate stability, exposure structure and rate plausibility, plus the risk-adjusted APY derived from it. Read the full yield methodology.

Data sources

  • DefiLlama stablecoins API — circulating supply, per-chain breakdown, prices and historical series.
  • DefiLlama yields API — pool-level APY and TVL used for the best-yield column and the yields screen.
  • DefiLlama protocols API — tokenized treasury and RWA assets under management.
  • Curated issuer dataset — issuer, jurisdiction, collateral type, attestation cadence, redemption terms and incident history, maintained in-repo from public disclosures.

Refresh cadence

Market data is cached server-side for a few minutes so the terminal stays fast and we stay inside upstream rate limits. Daily snapshots are written to our own database, which is what powers historical charts independent of any single upstream provider.

Limitations

  • Liquidity is estimated from tracked pools; off-chain and OTC depth is not visible.
  • Prices are aggregated and can lag venue-specific dislocations during a fast depeg.
  • Bridged versus canonical supply is not always distinguishable from upstream data; where it matters we flag it in the asset notes.
  • Nothing here is financial advice or a recommendation to buy or sell anything.
