Hey @papiporn, off topic from this thread but to directly answer your question about UIs and contracts for liquidity mining Uniswap v3 LP NFTs, we have what I believe is the first full suite front end at Frax Finance. For example, you can check out our Uni V3 farming pair UI and contracts here:
app .frax .finance/staking#Uniswap_V3_FRAX_USDC
We also allow locking the NFT LP for an additional boost to increase stickiness of the LP program. The farming contract also allows setting of range/ticks that are incentivized instead of generalized. The contract itself can be found here:
etherscan .io/ address/0x3EF26504dbc8Dd7B7aa3E97Bc9f3813a9FC0B4B0
I think the other protocol that might have full Uni v3 farming infrastructure other than FRAX is Gelato’s G UNI system. Maker is using them to manage their PSM module. I think they also are expanding it to generalized farming for end-users right now as well.
Hope that helps
