Once you have received pTokens from depositing assets in the PickleJars (guide here), then you are ready to stake your pTokens in the Farms for PICKLE rewards.
Navigate to https://app.pickle.finance/farms
Select the Farm you wish to stake in. You should select the Farm with the same “p” token that you already own.
Enter your desired stake amount and click “Approve and Stake”
A transaction will pop-up for you to sign to “Approve” this transaction.
After the transaction is complete, another transaction will pop up for you to sign to “Stake” the tokens.
Congratulations, you have successfully staked your pTokens in a Farm. This means your tokens are earning PICKLEs in addition to yields from the Pickle Jar.
