ONPROOF rates every token against 35 indicators across 8 categories, using a methodology disclosed in advance and sealed at review time. This page documents the full scoring framework — what we measure, how we weight it, and how grades are assigned.
ONPROOF is an independent token rating platform. Each review produces a single composite grade (A–F) and an underlying 0–100 score derived from the same 35-indicator rubric, regardless of token class. The methodology is disclosed in advance — weights and thresholds are not retroactively changed, and every report is sealed at review time with a snapshot of the rubric version it was scored against.
The methodology rests on three commitments:
Composite scores map to letter grades as follows. Category-level grades use the same scale.
| Grade | Description | Score range |
|---|---|---|
| A | Excellent | 90–100 |
| B | Good | 75–89 |
| C | Fair | 60–74 |
| D | Weak | 40–59 |
| F | Critical | 0–39 |
Category weights reflect each dimension's share of the composite score. Contract safety and holder distribution carry the heaviest weight because they directly affect downside risk; online presence and token economy alignment are lighter because they correlate with — but do not cause — risk.
Each category groups a small set of indicators that together describe a single dimension of risk or quality. Indicators are scored on a 0–5 scale and aggregated by simple weighted average within the category.

Each indicator is evaluated against an explicit rubric documented per indicator on the Token Report (Methodology & Data Snapshot section). The status determines the points contribution within the indicator's 0–5 scale:
Indicator meets or exceeds the rubric threshold. Earns full or near-full points.
Within acceptable range but with caveats. Earns partial points; flagged for monitoring.
Indicator falls below the rubric threshold. Earns zero or near-zero points.
Indicator is informational only — observed but not scored (e.g., descriptive metrics).
Indicator does not apply to this token class (e.g., LP locks for CEX-led tokens). Excluded from the category average.
Indicators marked N/A are excluded from the denominator, so a token isn't penalised for a dimension that doesn't apply. Indicators marked Neutral are observed but not scored.
NOTE — ONPROOF ratings are informational only and do not constitute investment advice. Ratings reflect the methodology disclosed in this whitepaper as of the snapshot recorded on each token report. Weights, formulas, and thresholds are not retroactively changed; subsequent methodology revisions apply only to reviews issued after the revision date. Disputes regarding any rating may be filed via the appeals process described above. ONPROOF is operated by The Monster Lab Inc. The methodology document is versioned; references to "v2.0" on this page should be read as the current version unless explicitly stated otherwise.
