Fee rewards can be collected separately apart from deposits. You can choose either to withdraw the rewards or reinvest them into the vault to earn more rewards.
The fee sharing for future Pika tokens are built into the smart contract. Before the token is launched, 70% of fees are distributed to vault, and 30% is for protocol revenue. After Pika token is launched, 50% of fees will be distributed to vault, 30% to Pika stakers and 20% to the protocol.
