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.
|
|
|
|
[address.json](https://github.com/oceanprotocol/contracts/blob/v4main/addresses/address.json) holds up-to-date deployment addresses for all Ocean contracts.
|
|
|
|
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 also need "fake" native tokens for testnets; you typically get these from faucets.
|
|
|
|
## 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 Mainnet
|
|
- Moonriver
|
|
|
|
**Test Networks:**
|
|
- Görli
|
|
- Sepolia
|
|
- Mumbai
|
|
- Oasis Sapphire testnet
|
|
- Optimism Sepolia
|
|
|
|
The rest of this doc gives details for each network. You can skip it until you need the reference information.
