Scores
Each criterion carries equal weight. The overall score is the average of these 6 scores — (8.0 + 5.0 + 5.0 + 10.0 + 10.0 + 0.0) ÷ 6 = 6.3.
Pros
- Documents its distribution mechanism: one Merkle root per chain, a public reward file per update, and a dispute window with a forfeitable bond
- Case studies describe concrete anti-farming rules, such as World ID verification with per-user caps on World Chain
- Live campaigns, APRs and daily rewards are public without a login
Cons
- Case-study outcome figures have no method, and one page says results are not solely attributable to the program
- Some named campaigns give no amount
- No disclosure of ties to campaign creators or reward recipients

How Merkl scores, criterion by criterion
Each mark comes from a fixed scale published on our methodology page, and each links to the page it was read from.
| Criterion | Mark | What we found | Source |
|---|---|---|---|
| Named programs | 8 | Names Optimism Superfest (OP Mainnet, Base, Mode and Fraxtal; eight weeks), World Chain human-verified rewards (April to October 2025), Plasma launch incentives (from 25 September 2025, six months) and Aave campaigns (from mid-2024). | merkl.xyz, read 2026-09-22 |
| Disclosed volume | 5 | Amounts are stated for Superfest (1.5 million OP), World Chain (about $5 million) and Aave (over $65 million to date) but not for Plasma. | merkl.xyz, read 2026-09-22 |
| Impact report | 5 | The Superfest case study reports more than $100 million in liquidity added and $66 of TVL per OP, with no method, and notes the results were not solely attributable to the program. | merkl.xyz, read 2026-09-22 |
| Abuse protection | 10 | On World Chain only Orb-verified World ID holders were rewarded, capped at deposits of 1,000 WLD and 1,000 USDC per user; campaigns can also exclude blacklisted addresses or positions below a health factor. | merkl.xyz, read 2026-09-22 |
| Open data | 10 | Each reward update publishes a public reward file, and the app lists campaigns with APR, TVL and daily rewards without a login. | docs.merkl.xyz, read 2026-09-22 |
| Independence | 0 | Not published. | merkl.xyz, read 2026-09-22 |
Merkl publishes nothing we could find on independence, so that criterion scores 0. That is a record of what is published, not a finding about what the firm does privately.
