Receiving ARB incentives is great news and I am in favor of doubling-down with UNI incentives.
While Arbitrum is the largest non-Ethereum market for Uniswap in terms of TVL and trading volumes, it is lagging behind Base in terms of fees generation. Considering the large amount of incentives and the ongoing discussion on the fee-switch, this seems an interesting challenge.
While ARB incentives (as per the LTIPP application) will be focused on optimizing TVL gained per incentive spend and volume gained per incentive spend, it would be interesting for the UNI portion to be dedicated at improving fee-generation from the Arbitrum ecosystem. Or, to see how the ARB + UNI incentives impact fee-generation.
