--- title: Ocean Tokens description: The technical basics and most important infos about Ocean Tokens in different networks. --- ## Basics **Ocean Tokens** are the [cryptocurrency](https://en.wikipedia.org/wiki/Cryptocurrency) associated with Ocean Protocol. They are standards-compliant [ERC-20 tokens](https://en.wikipedia.org/wiki/ERC-20). Ocean Tokens can, in principle, live in any EVM-compatible network. The Ocean Token contract is deployed in the Ethereum Mainnet, Pacific Mainnet, and the Nile Testnet. Only OCEAN within the Ethereum Mainnet carry any value, reflected [on our token page](https://oceanprotocol.com/token). | Property | Value | | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Token Contract Addresses | _Ethereum Mainnet_

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. 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 - provide liquidity in decentralized exchanges like Uniswap or Balancer ### 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: #### Ocean Token Tool Enter your account address into the form on the [Ocean Token page on our website](https://oceanprotocol.com/token#balance). [![Ocean Token Tool](images/token-tool.png)](https://oceanprotocol.com/token#balance) #### Blowfish Download and use [Blowfish](https://github.com/kremalicious/blowfish), a desktop app that tells you your Ocean Token balance (and other things). [![Blowfish](images/blowfish.png)](https://github.com/kremalicious/blowfish) #### MetaMask Use MetaMask or other ERC-20-compatible wallet software. See the page about [using wallet software to manage Ocean Tokens](/tutorials/wallets-and-ocean-tokens/). You can also use wallet software to send Ocean Tokens to some other account. #### Etherscan Go to [Etherscan](https://etherscan.io/), 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. ### Buy or Sell Ethereum Mainnet Ocean Tokens You can buy or sell Ethereum Mainnet Ocean Tokens (OCEAN) via any exchange that lists them. An always up-to-date _official list_ of exchanges can be found on the [Ocean Token page on our website](https://oceanprotocol.com/token#balance). ## Pacific Network Ocean Tokens Ocean Tokens in Ocean's Mainnet, [Pacific](/concepts/pacific-network/), represent the same value as in the Ethereum Mainnet. The only way to get Ocean Tokens in Pacific is to transfer them from the Ethereum Mainnet. ## Testnet Ocean Tokens There are Ocean Tokens in several testnets, including the 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](/concepts/testnets/) and the [tutorials](/tutorials/introduction/). 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: - [`OceanAccounts.requestTokens()`](/references/squid-js/#OceanAccounts-requestTokens) - [`Account.requestTokens()`](/references/squid-js/#Account-requestTokens) - The squid-py docs for: - [the `squid_py.ocean.ocean_tokens` module](https://squid-py.readthedocs.io/en/develop/api/squid_py.ocean.ocean_tokens.html): see the `request()` method. - [the `squid_py.ocean.ocean_accounts` module](https://squid-py.readthedocs.io/en/develop/api/squid_py.ocean.ocean_accounts.html): see the `request_tokens()` method. - [The squid-java docs](https://www.javadoc.io/doc/com.oceanprotocol/squid/): 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](/tutorials/example-code/) has links to example Squid code (in all of the languages), including examples of using the above methods. ## Further Reading about Ocean Tokens - [Ocean Token page](https://oceanprotocol.com/token) - [Tutorial: Use Your Wallet to Manage Ocean Tokens](/tutorials/wallets-and-ocean-tokens/) - [Blog: Ocean Tokenomics](https://blog.oceanprotocol.com/ocean-tokenomics-d34f28c480a8) - [Blog: Ocean Tokenomics II](https://blog.oceanprotocol.com/https-blog-oceanprotocol-com-ocean-tokenomics-ii-faf05854314b) - [Ocean Protocol Technical Whitepaper](https://oceanprotocol.com/tech-whitepaper.pdf) - [Blog: What Happened with the IEO?](https://blog.oceanprotocol.com/what-happened-with-the-ieo-54cc5c6c3db9) - [Blog: Ocean Protocol — Token Sale](https://blog.oceanprotocol.com/ocean-protocol-token-sale-96d03f968e22) - [Blog: Ocean Protocol Pre-Launch is Target Reached](https://blog.oceanprotocol.com/ocean-protocol-pre-launch-is-target-reached-d10e53272a2e)
