Deploy Aave V3 to Metis Andromeda Mainnet
Vote Result: NO
Rationale
Having judged this proposal through a risk vs. reward perspective, i.e., is the risk of deploying on Metis higher than the potential reward, we have come to the conclusion of voting NO.
Before we dive into the reasons for voting NO, we recognise there are a few reasons to vote in favour. Firstly, implementing Aave v3 on Metis would help Aave expand to other chains and build a strong presence on the L2 ecosystem. Secondly, it is a fork of Optimism and hence development effort is not high. Lastly, 30% of the fees accrued from every transaction will be directed towards Aave in perpetuity, which is beneficial for Aave overall.
However, we believe that the reasons to vote against are stronger and counteract some of the purported benefits of deploying on Metis:
Security
Metis has not yet implemented its technical roadmap - data is not posted on-chain, and Sequencer rotation is not yet supported which reduces the security of the system. As pointed out by L2 Beat, without running the verifier dtl, independent observers cannot verify if the posted state root is correct if the data is not posted on-chain. Therefore, if data is missing from the MEMO lab’s storage, then there is no clear plan of action for independent users. When compared to Optimism, which Metis can be closely compared to given that it is forked from Optimism, users can prove that the state root is invalid and notify the community that fraud is happening, and the community can respond in 7 days using social means. In the case of Metis, all users can do is to complain that, according to them, data is missing in the MEMO lab’s storage without knowing if the posted state root is valid or not. This reduces overall security for the system, and for Aave.
TVL, Activity, and Traction
The TVL of Metis is low and market potential is not very high in general, with no discernible reasons to use Metis over other L2s for users. As per this comparison, Metis is slower and more expensive than Optimism, which calls into question its purported benefits and therefore impacts network adoption. If network adoption is low, then revenues that accrue to Aave are low as well.
Metis is the chain with the second-smallest TVL out of all the chains Aave has deployed to, with Harmony being the smallest chain. However, Harmony has faced issues over the last few months, and TVL has dropped significantly, from a peak of $1.82 billion in January 2022 to $7 million today. This drop is almost all of its TVL (reduction of 99.6%), and over the same period, is much higher than the drop in TVL of the other chains Aave is deployed on (Polygon is down 79%, Arbitrum is flat, Optimism’s TVL has increased, and Avalanche is down 86%). This serves to highlight the point that Aave should, as a flagship DeFi protocol, deploy on chains that are battle-tested, more secure, have higher liquidity, and higher potential for growth, with lower probability of bad debt on Aave.
Metis’ Current State of Development
As explained by @Peter88, one of the co-founders of Metis, there is only a high-level roadmap that can be provided by Metis at the moment. This indicates that Metis is still very early on in its development. Aave is a flagship DeFi protocol and should only deploy on chains with the highest level of security and user activity. At the moment, it seems as if Metis is a level below this and it may be more prudent to wait for Metis to further fulfil its roadmap.
