title description
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.
