Scores
Each criterion carries equal weight. The overall score is the average of these 5 scores — (8.0 + 9.0 + 3.0 + 2.0 + 7.0) ÷ 5 = 5.8.
Pros
- Fee published as a 10% technical service fee from staking rewards
- ankrETH is value-accruing: quantity stays fixed, value rises against ETH
- Two exit routes: standard unstake, or flash unstake that is instant for a stated 0.5% commission
- Audits named: Beosin, dated 2020 and 2022, and Salus, 2023
- Minimum unstake stated at 0.5 ETH
Cons
- The operator set is described only as trusted and reputable, with no count or permission model
- No official ankrETH contract repository with a licence file could be identified
- Flash unstake is limited by the flash pool's capacity
A priced instant exit
Ankr offers two routes out: a standard unstake whose timing depends on the Ethereum exit queue, and a flash unstake that is instant for a stated 0.5% commission, limited by the flash pool's capacity. Publishing both the option and its exact price is what this criterion rewards, and it earns Ankr a high exit score.
Fee and audits are clear
The technical service fee is published at 10% of staking rewards, and audit reports are named and dated — Beosin in 2020 and 2022, Salus in 2023.
Two gaps
The operator set is described only as trusted and reputable validator nodes, with no count or permission model stated, and no official ankrETH contract repository with a licence file could be identified. Both hold down the decentralisation and licence scores, and the review states what could not be found rather than guessing at it.
