Networks

All the public networks the Ocean Protocol contracts are deployed to.

Ocean Protocol's smart contracts and OCEAN are deployed on multiple public networks: several production chains, and several testnets too.

The file address.json holds up-to-date deployment addresses for all Ocean contracts.

On tokens:

You need the network's native token to pay for gas to make transactions: ETH for Ethereum mainnet, MATIC for Polygon, etc. You typically get these from exchanges.
You may get OCEAN from an exchange, and bridge it as needed.
For testnets, you'll need "fake" native tokens to pay for gas, and "fake" OCEAN. Typically, you get these from faucets.
Below, we give token-related instructions, for each network.
