NOTICE: Below we outline some plans at the time of writing. Those plans might change. We will update this page on a regular basis.
Basics
Ocean Tokens are the cryptocurrency associated with Ocean Protocol. They are standards-compliant ERC-20 tokens.
| Property | Value |

| Token Contract Address | See the tutorial |
| Token Symbol | OCEAN |
| Decimals of Precision | 18 |
Testnet Ocean Tokens
There are Ocean Tokens in several testnets, including the Kovan testnet and Nile testnet. They are just testnet Ocean Tokens (i.e. for testing purposes only) and they aren't interchangeable with Ethereum Mainnet Ocean Tokens. For more details, see the the page about Testnets and the tutorials.
Testnet Ocean Token Utility
Once you have some Testnet Ocean Tokens, you can use them for all currently-implemented Ocean Protocol tasks in that testnet (e.g. buying assets).
Get Testnet Ocean Tokens
All Squid libraries have methods to request Ocean Tokens. They work by calling the "Dispenser" keeper contract, a contract which is only deployed to testnets. Therefore they will only work in testnets. They're documented in the following places:
- The squid-js docs for:
- The squid-py docs for:
- the
squid_py.ocean.ocean_tokensmodule: see therequest()method. - the
squid_py.ocean.ocean_accountsmodule: see therequest_tokens()method.
- the
- The squid-java docs: click "All Classes" then "AccountsManager" then scroll to the bottom of the Class AccountsManager page where you'll find the
requestTokens()method.
The Example Code page has links to example Squid code (in all of the languages), including examples of using the above methods.
Ethereum Mainnet Ocean Tokens
There were several ways to acquire some of the Ethereum Mainnet Ocean Tokens in the initial circulating supply, including:
- participation in the seed round
- participation in the pre-sale
- participation in the token sale
- participation in the initial exchange offering
- completion of a bounty
After the initial exchange offering on Bittrex International, Ethereum Mainnet Ocean Tokens became available in the Ethereum Mainnet (not the Ocean Production Network; there was no Ocean Production Network at the time). The initial circulating supply of Ethereum Mainnet Ocean Tokens became available on the Ethereum Mainnet in May 2019. If you acquired Ocean Tokens in the initial circulating supply, they should have been, or will be, sent to the address you provided, in the Ethereum Mainnet.
How to Check Your Ethereum Mainnet Ocean Token Balance
There are many ways to check your Ethereum Mainnet Ocean Token balance. Starting with the easiest, here are some ways:
- Enter your account address into the form at https://wallet.oceanprotocol.com/tokens
- Go to Etherscan, enter your account address into the search field, click Search, click on Erc20 Token Txns, look for an "OceanToken" transaction in the "Token" colum, and click on OceanToken there.
- Download and use Blowfish, a desktop app that tells you your Ocean Token balance (and other things).
- Use MetaMask or other wallet software. See the page about using wallet software to manage Ocean Tokens. You can also use wallet software to send Ocean Tokens to some other account.
Ethereum Mainnet Ocean Token Utility
At the time of writing, you could use Ethereum Mainnet Ocean Tokens to do various things in the Ethereum Mainnet, including but not limited to:
- buy other cryptocurrencies. See the next subsection for more details.
- stake in dxDAO.
Moreover, in the near future, there are plans to make it possible to use Ethereum Mainnet Ocean Tokens for Ocean Protocol tasks in the Ethereum Mainnet. That includes asset and service acquisition, via Ocean Protocol marketplaces attached to the Ethereum Mainnet.
How to Buy or Sell Ethereum Mainnet Ocean Tokens
You can buy or sell Ethereum Mainnet Ocean Tokens via any exchange that lists them. See the official list of exchanges below.
You could also make a deal with someone where you send them something and they send you some Ocean Tokens in return (or vice versa). Ethereum Mainnet Ocean Tokens are standard ERC-20 tokens, so any software that can send ERC-20 tokens can be used (e.g. wallet software such as MetaMask).
Official List of Exchanges
Below is the official list of exchanges which listed Ethereum Mainnet Ocean Tokens (OCEAN), at the time of writing:
Ocean Production Network Ocean Tokens
At the time of writing, the Ocean Production Network wasn't deployed yet, so there were no Ocean Production Network Ocean Tokens.
At some point after the Ocean Production Network is launched, it will become possible to move Ocean Tokens from the Ethereum Mainnet to the Ocean Production Network. The details of exactly how that will work are still to be determined.
