How to use a crypto wallet to check your OCEAN balance and send OCEAN Tokens to others

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:

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.
