BUIDL across four dimensions
Each dimension is scored out of 25, then multiplied by its weight and summed into the /100 composite — so the four dimension scores are a weighted, not a plain, sum. Last scored Aug 26, 2026 on methodology v1.2.
| Dimension | Score | Weight |
|---|---|---|
| Disclosure Quality | 6 / 25 | ×0.4 |
| Redemption Liquidity | 17 / 25 | ×0.9 |
| Structural Trust | 20 / 25 | ×1.4 |
| Holder Concentration | Not measured | ×1.3 |
| CompositeΣ (score × weight) | 68 / 100 |
Holder Concentration is withheld for this instrument. Its holder base is too large or too widely distributed to measure to ground truth, so the concentration figure is not published. The composite reflects the three measured dimensions, renormalized.
