Scores
Each criterion carries equal weight. The overall score is the average of these 5 scores — (8.0 + 8.0 + 6.0 + 2.0 + 9.0) ÷ 5 = 6.6.
Pros
- Fee published: 10% of rewards for mETH, 20% for cmETH restaking
- mETH is a value-accumulating receipt token, not rebasing
- Redemption has a minimum 12-hour delay and, notably, no fee
- Five operators named: A41, P2P, Blockdaemon, stakefish and Kraken
- Audits published in a dedicated repository by Blocksec, Exvul, Hexens, MixBytes and Verilog
Cons
- The mantle-lsp contracts repository has no LICENSE file — published code with no grant of rights
- Only five operators, permissioned rather than open
- Maximum redemption time can reach 40+ days depending on the validator exit queue
Redemption without a fee
Mantle charges 10% of rewards on mETH and 20% on cmETH restaking, and states that redemption carries a minimum 12-hour delay with no fee, extending to 40 days or more at the tail depending on the Ethereum validator exit queue. A no-fee redemption is worth noting in a category where several peers charge for a fast exit.
Operators named, audits published
The five operators are named — A41, P2P, Blockdaemon, stakefish and Kraken — which is honest, if permissioned. Audit reports sit in a dedicated repository from Blocksec, Exvul, Hexens, MixBytes and Verilog, a strong disclosure.
The licence gap
Against all that, the mantle-lsp contracts repository carries no LICENSE file on its main branch. Code published without a licence reserves every right by default, which is the weakest position on this criterion and the reason the licence score sits at the bottom despite the protocol's otherwise solid disclosure.
