# Supported Networks

## Supported Networks

Ocean Enterprise smart contracts are deployed across multiple public networks, including several production chains and several testnets.

The file [`address.json`](https://github.com/oceanprotocol/contracts/blob/v4main/addresses/address.json)  holds up-to-date deployment addresses for all Ocean contracts.

### Networks Summary

The networks where Ocean Enterprise smart contracts are deployed are:

**Production Networks:**

* Ethereum Mainnet
* Optimism (OP) Mainnet

**Test Networks:**

* Ethereum Sepolia
* Optimism (OP) Sepolia

### Production Networks

The smart contracts deployed by O.E.C. in the production networks and used by default by the Ocean Enterprise components are available at the following addresses.
