To withdraw your funds, open the Farming section and select the farm where your LP tokens are deposited. Click the withdraw option and choose whether to remove all or only part of your LP tokens. The interface will show what you're about to unstake before you approve it. Confirm the withdrawal and approve the transaction in your TON wallet. Your LP tokens are then returned to your wallet instantly. If you want to fully exit your liquidity position, go to the corresponding pool and redeem those LP tokens for the underlying assets.
Withdrawing LP tokens from a farm requires Gram (formerly Toncoin) in your wallet to cover the blockchain fee. You can see the exact amount in the STON.fi interface in the Blockchain fee field before signing the transaction. For more on STON.fi fees, see our Blockchain and swap fees guide.
