Liquidity provision means providing token pairs to a pool so that other users can swap. Liquidity providers receive a share of the swap fees collected by the pool — by default this is 0.2% per swap, though the exact fee depends on the specific pool. The fee accrual is split proportionally among all liquidity providers in that pool.
Farming usually refers to depositing LP tokens into a separate rewards contract so they accrue extra incentives on top of swap fees. Farming rewards come from the project running the farm (or from STON.fi-led campaigns) and are paid in additional tokens. Reward rates are variable.
Staking involves locking a single token (not a pair) to support the protocol and receive rewards. For STON staking specifically, the reward in GEMSTON is paid as a one-time amount at the moment of staking, not gradually over time.
Liquidity provision exposes you to impermanent loss; staking typically does not. Farming adds an additional reward layer but often comes with higher smart-contract risk. Each method suits different goals: protocol-fee accrual, additional incentives, or governance participation. Outcomes are variable in all three cases.
