To use the liquidity lockers, the fee model is very simple. There is a flat fee (ETH, xDai, BNB.. depending on the blockchain from where you are using the service) and a percentage of the LP tokens locked.
For very large locks, there is a second fee option, consisting of burning UNCX to receive a discount on the UNIv2 fees.
These options can be chosen while interacting on our UI.
We could summarize it in the table below :
Flat fee + % of LP tokens locked
UNCX burnt + reduced % of LP tokens locked
