Incentives should be provided on Base soon to avoid a cold-start scenario, where substantial liquidity for the new UP token is not reached quickly, which leads to a lack of motivation for new lps. Gamma is a trusted tool with a long track-record. I recommend using Gamma rather than the proposed Ichi single-sided liquidity, in order to keep things simple.
Start with $8k per month for an initial period of 2 months. Given the current mainnet price for UDT is $7.20, at 1000 UP / 1 UDT ratio, the initial price of UP would be $0.0072
$8,000 / $0.0072 = 1,111,111 UP rewards per month For a total of 2,222,222 UP (0.22% of supply)
Other considerations: The bridge and swap app https://up-swap.unlock-protocol.com/ should be updated to recommend adding liquidity to earn rewards. Instructions should be clear that liquidity should be added using the Gamma app in order to receive rewards.
