# Manage Your OCEAN

If you don't see any OCEAN in your crypto wallet software 🔎 (e.g. MetaMask or MyEtherWallet), don't worry! It might not know how to manage OCEAN yet.

### Token Information

Almost all ERC-20 wallets require these values for adding a custom token:

<table data-full-width="false">
   <thead>
      <tr>
         <th width="161">Network name</th>
         <th width="444">Contract Address</th>
         <th width="105">Symbol</th>
         <th>Decimals</th>
      </tr>
   </thead>
   <tbody>
      <tr>
         <td><strong>Mainnet</strong></td>
         <td>0x967da4048cD07aB37855c090aAF366e4ce1b9F48</td>
         <td>OCEAN</td>
         <td>18</td>
      </tr>
      <tr>
         <td><strong>Polygon</strong><br><strong>(ex Matic)</strong></td>
         <td>0x282d8efCe846A88B159800bd4130ad77443Fa1A1</td>
         <td>mOCEAN</td>
         <td>18</td>
      </tr>
      <tr>
         <td><strong>BNB</strong><br><strong>BNB Smart Chain</strong></td>
         <td>0xdce07662ca8ebc241316a15b611c89711414dd1a</td>
         <td>OCEAN</td>
         <td>18</td>
      </tr>
      <tr>
         <td><strong>Görli</strong></td>
         <td>0xCfDdA22C9837aE76E0faA845354f33C62E03653a</td>
         <td>OCEAN</td>
         <td>18</td>
      </tr>
      <tr>

         <td>0xd8992Ed72C445c35Cb4A2be468568Ed1079357c8</td>
         <td>OCEAN</td>
         <td>18</td>
      </tr>
      <tr>
         <td><strong>Sepolia</strong></td>
         <td>0x1B083D8584dd3e6Ff37d04a6e7e82b5F622f3985</td>
         <td>OCEAN</td>
         <td>18</td>
      </tr>
      <tr>
         <td><strong>Oasis Sapphire</strong></td>
         <td>0x39d22B78A7651A76Ffbde2aaAB5FD92666Aca520</td>
         <td>OCEAN</td>
         <td>18</td>
      </tr>
   </tbody>
</table>

### MetaMask

1. Make sure MetaMask is connected to the Ethereum Mainnet.
2. Select the account you want to manage.
3. Scroll down until the `Import Tokens` link is visible, then click on it.
4. Click on `Custom Tokens`.
5. Paste the OCEAN contract address listed above into the _Token Contract Address_ field. The other two fields should auto-fill. If not, add `OCEAN` for the symbol and `18` for the precision.
6. Click `Add custom token`.
7. Click `Import Tokens`.

If you prefer visual demonstrations, we have prepared a visual demo that illustrates the steps mentioned above.

MetaMask should now show your OCEAN balance, and when you're looking at that, there should be a `Send` button to send OCEAN to others. For help with that, see [the MetaMask docs about how to send tokens](https://metamask.zendesk.com/hc/en-us/articles/360015488931-How-to-Send-Tokens).
