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.

## Token Information

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

**Mainnet**

- Contract Address: `0x967da4048cD07aB37855c090aAF366e4ce1b9F48`
- Symbol: `OCEAN`
- Decimals: `18`

**Rinkeby**

- Contract Address: `0x8967BCF84170c91B0d24D4302C2376283b0B3a07`
- Symbol: `OCEAN`
- Decimals: `18`

**Ropsten**

- Contract Address: `0x5e8DCB2AfA23844bcc311B00Ad1A0C30025aADE9`
- Symbol: `OCEAN`
- Decimals: `18`

**Polygon Mainnet (previously Matic)**

- Contract Address: `0x282d8efCe846A88B159800bd4130ad77443Fa1A1`
- Symbol: `mOCEAN`
- Decimals: `18`

The [OCEAN Token page](https://oceanprotocol.com/token) 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](https://metamask.zendesk.com/hc/en-us/articles/360015488931-How-to-Send-Tokens).
