# Networks

Ocean Protocol contracts are deployed on multiple public networks. You can always find the most up-to-date deployment addresses for all individual contracts in the [address.json](https://github.com/oceanprotocol/contracts/blob/v4main/addresses/address.json).

In each network, whether it's the Ethereum mainnet, a testnet, or the Polygon/Matic network, you'll need ETH or Matic to pay for gas and OCEAN for certain actions on the Ocean Protocol network. The Ethereum mainnet and the Polygon network are both live networks and the tokens on these networks have real value. However, the tokens on the test networks are not of real value and are only used for testing purposes. You can obtain testnet ETH and OCEAN from faucets, which are services that provide small amounts of tokens for free.

### Ethereum Mainnet

The Ethereum mainnet is a production network, which means that it is a live and operational network that handles real transactions and has actual economic value. To connect to the Ethereum mainnet using a wallet such as MetaMask, you can click on the network name dropdown and select Ethereum mainnet from the list of available networks.

### Polygon Mainnet

Ocean Protocol is also deployed to Polygon Mainnet, which is another production network. The native token of Polygon Mainnet is MATIC. If you cannot find Polygon Mainnet as a predefined network in your wallet, you can manually connect to it by following Polygon's [guide](https://wiki.polygon.technology/docs/develop/metamask/config-polygon-on-metamask/#add-the-polygon-network-manually), which provides step-by-step instructions for connecting to Polygon Mainnet.

### Oasis Sapphire Mainnet

Ocean Protocol is also deployed to Oasis Sapphire Mainnet, which is a production network that Ocean Protocol uses for [Predictoor](https://predictoor.ai). Ocean Protocol does do not currently support ocean.js, ocean.py, or Ocean Market on Oasis Sapphire. The native token of Oasis Sapphire is ROSE. If you cannot find Oasis Sapphire Mainnet as a predefined network in your wallet, you can manually connect to it by entering the following information during the import process: Network Name: `Oasis Sapphire`, RPC URL: `https://sapphire.oasis.io`, Chain ID: `23294`, Token: `ROSE`.
