Introduction
Yield Farming or Liquidity Mining is a aspect of DeFi that allows Liquidity Providers (LPs) to passively earn a return on capital contributed to a liquidity pool. The Yield Farm provides LPs with rewards over time to incentivize LPs to continue to provide liquidity to the pool as well as to help offset their risk.
This guide covers yield farming on KyberSwap Classic.It covers the following aspects of yield farming on KyberSwap Elastic:
- Staking LP Tokens
- Harvesting and Claiming Rewards
- Unstaking LP Tokens
Staking LP Tokens
Step 1: Approve and add liquidity to the farm of your choice. A guide on how to do this can be found here. For the purposes of this guide, we will use the following USDC-miMATIC pool on Polygon.
Step 2: From the Active tab on the Classic Farms page, click on the “+” button associated with your farming pool to bring up the Stake window.
The Stake window should show you the balance you have in the pool. Click on the “Approve” button on the Stake window to give the farming smart contract permission to stake your LP tokens.
This is an onchain transaction that will require confirmation in your web3 wallet.
Step 3: From the Active tab on the Classic Farms page, click on the “+” button once more to bring up the Stake window. Now that you have given the farming smart contract permission to access your LP tokens, the Stake window should look different. You can now specify the amount of LP tokens to stake either by manually typing in an amount or by using the “max” and “half” buttons. Click the “Stake” button to proceed.
This is an onchain transaction that will require confirmation in your web3 wallet.
Once you’ve confirmed the transaction you will see a screen informing you that the transaction has been submitted. You can click on “View Transaction” to view your transaction on the appropriate blockchain explorer.
Your LP tokens are now staked and you are eligible to accumulate rewards for as long as your LP tokens remain staked. You should now also be able to see your farming pool under the “My Farms” tab.
Harvesting and Claiming Rewards
After you have accumulated rewards, you can harvest them from the pool and subsequently claim them (i.e. withdraw rewards to your wallet).
Step 1: From the Farms page, click on the small “pickaxe” button associated with your desired pool to bring up the Harvest screen. Alternatively, if you have multiple pool farms and would like to harvest them all at once, you can use the “Harvest All” button to batch all the harvest transactions together. Please note that this does not save you any gas fees since every individual harvest call of the smart contract still needs to be broadcast to the blockchain.
From the Harvest (or Harvest All) screen that appears, click on the “Harvest” button to proceed. This is an onchain transaction that will require wallet confirmation.
If the pool does not have a rewards vesting schedule, your rewards will automatically be sent to your wallet. But if the pool has a vesting schedule, you will need to wait some time after harvesting for the rewards to vest before you can claim them.
Step 2: This step only applies to certain pools with a vesting schedule for rewards. Rewards harvested from such pools will need to be claimed in a separate action. Click the “Claim” button in the Vesting tab of the Farms page.
Note: The vast majority of active yield farming pools on KyberSwap do not have a vesting schedule, and these do not require this separate claim step.
Unstaking LP Tokens
You may also choose to unstake your LP Tokens from a farming pool at any time. This will return LP tokens to your wallet and you will cease earning liquidity mining rewards from the pool. On the other hand, this will free up your liquidity in the pool and you will once again be able to withdraw it.
Step 1: On the Farms page, click on the “-” button of the pool you would like to unstake LP tokens from. On the screen that opens, specify the amount of LP tokens you would like to unstake, and then click the “Unstake” button. This is an onchain transaction. As part of this action, any as-yet unharvested rewards will also automatically be harvested.
