There is a 6 week scaling tax set AT LAUNCH. Meaning after the first 6 weeks of Walrus, there will be no penalty tax for unstaking LP.
Example: Dylan creates a WLRS/USDC.e LP worth $200 and deposits the LP in the WLRS/USDC.e farm. After exactly 1 week, he wishes to unstake his position and withdraws his LP. He will incur a tax of 4% tax (or $8, assuming the value of the LP remains unchanged at $200). His new position will be $192 worth of WLRS/USDC.e LP.
