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

Networks

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.

Networks Summary

Here are the networks that Ocean is deployed to.

Production Networks:

• Ethereum mainnet
• Polygon mainnet
• Oasis Sapphire mainnet
• BNB Smart Chain
• Energy Web Chain
• Optimism (OP) Mainnet
• Moonriver

Test Networks:

• Görli
• Sepolia
• Mumbai
• Oasis Sapphire testnet
• Optimism (OP) Sepolia

The rest of this doc gives details for each network. You can skip it until you need the reference information.
