When you select a stake account and click the 'Unstake it' button, our program transfers the selected stake account from you to our SOL pool and transfers the same amount of SOL, minus the displayed fee, from our SOL pool to you in return.
Liquidity providers (LPs) provide a single pool of liquid SOL. When you use unstake.it, we give you the liquid SOL in exchange for your stake account. We then unstake your stake account to replenish the pool, and take a small fee to compensate the LPs.
