Once you have a balance of EPS within your wallet, either by earning it or purchasing it on PancakeSwap, you can choose to "lock" it within the fee distribution contract. Locked EPS cannot be withdrawn for 90 days - it is NOT possible to pay a penalty to withdraw locked EPS early.
Locking demonstrates a commitment to the long-term vision of Ellipsis. Along with receiving the regular trade fees, users who lock EPS receive 100% of the penalty fees paid by users who withdraw vested tokens. Distribution of exit penalty fees begins immediately when a vested user withdraws early, and are released evenly over the following seven days.
