[ARFC] Add rETH to Aave V3 Arbitrum Liquidity Pool
Vote Result: YES
Rationale
rETH is already listed on Aave Ethereum v3 and expanding it to Arbitrum is a logical next step. Adding more established LSTs like rETH to Aave drives revenue as users deposit the LST and borrow ETH. This is most evident on Ethereum where the LST- and wETH-yield-maximising loop is the source of the vast majority of wETH borrowing demand. Another important point is that of LST diversification - Rocket Pool offers Aave v3 users on Arbitrum an alternative to wstETH, which is very important. Lastly, Chaos Labs and Gauntlet are in favour of this proposal and the risk parameters presented match those on Ethereum v3 and are a combination of the most cautious parameters presented by both risk providers, enabling appropriate risk management.
