Farming is represented in the form of liquidity mining, when the user adds the liquidity into the DEX pool, receives LP tokens in exchange, and then deposits them in the protocol's MasterChef contract to receive ORU token as a reward.
The emission rate for liquidity providers can be found at:
Early exit penalty
ORU / oUSD LP
ORU / USDC LP
oUSD / USDC LP
If the user deposits more LP into the oUSD / USDC pool, the lock-up period is reset to 3 days.
