How to use crypto wallet software to check your Ocean Token balance and to send Ocean Tokens to others.

Use Your Wallet to Manage OCEAN Tokens

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

The OCEAN Token page at oceanprotocol.com has further details.

MetaMask

1. Make sure MetaMask is connected to the Ethereum Mainnet.
2. Select the account you want to manage.
3. Scroll down until the Add Token link is visible, then click on it.
4. Click on Custom Token.
5. Paste the Ocean Token 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 Next.
7. Click Add Tokens.

MetaMask should now show your Ocean Token (OCEAN) balance, and when you're looking at that, there should be a Send button to send Ocean Tokens to others. For help with that, see the MetaMask docs about how to send tokens.
