In order to **get yield in DF**, you will need to lock your OCEAN first! When you lock your OCEAN, you get **veOCEAN** and **weekly passive OCEAN rewards** in return. veOCEAN is a token used in Ocean Protocol's Data Farming dApp to **generate even more yield,** called **Volume DF rewards**, for allocating your veOCEAN to your favorite assets and get a portion of their sales!
### Don't have OCEAN yet? Get those first!
#### Step 1 - Get OCEAN
- Acquire OCEAN via a decentralized exchange (DEX) such as Uniswap or a centralized exchange (CEX) such as Binance, Coinbase, etc.
#### Step 2 - Send to your self-custody wallet
- Send your OCEAN to a self-custody wallet of yours that supports ERC-20 tokens, like Metamask for example.
- Enter the amount of OCEAN that you are going to lock up
- Select a Lock End Date indicating how many weeks you’re going to lock up your OCEAN. (As the Lock End Date goes farther into the future, your Lock Multiplier increases).
- Click on the checkbox to agree to the disclaimer.
Congratulations! You have now locked your OCEAN for veOCEAN and are generating passive yield automatically. You can [claim your passive OCEAN rewards](claim-rewards.md) every Thursday - note that your first time claiming rewards will require at least one week, but not more than 2 weeks of wait!
