## The Kovan Testnet
The [Kovan Testnet](https://github.com/kovan-testnet/proposal) (or just "Kovan") is a public Ethereum testnet operated by members of the Ethereum community.
The [Kovan Testnet](https://github.com/kovan-testnet/proposal) (or just "Kovan") is a public Ethereum Testnet operated by members of the Ethereum community.
Most Ethereum wallets and libraries know how to connect to the Kovan Testnet. If you're using [Barge](https://github.com/oceanprotocol/barge) to run a local Kovan node, you can connect to that local Kovan node at RPC URL [http://localhost:8545](http://localhost:8545) (called "Localhost 8545" in MetaMask).

## The Nile Testnet
_Formerly called the Ocean POA Testnet._
The Nile Testnet is similar to the Kovan Testnet, except all the nodes are operated by BigchainDB GmbH.
If you want to connect to the Nile Testnet e.g. using MetaMask, then you must enter an "RPC URL" for the Nile Testnet. It is:
[https://nile.dev-ocean.com/](https://nile.dev-ocean.com/)
### Nile Testnet Parameters
(You don't need to include the port number.)
Parameter | Value
-------------------|---------------
RPC URL (required) | [https://nile.dev-ocean.com/](https://nile.dev-ocean.com/)
ChainID | 8995 (decimal for MetaMask) or 0x2323 (hexadecimal)
Symbol | Whatever you like
Nickname | Whatever you like
- In MetaMask, you don't need to include the port number with the RPC URL.
- If you're using MetaMask, see the [MetaMask docs about how it uses the ChainID](https://metamask.github.io/metamask-docs/Main_Concepts/Sending_Transactions).
- If you're using [Barge](https://github.com/oceanprotocol/barge) to run a local Nile node:
- You can connect to that local Nile node at RPC URL [http://localhost:8545](http://localhost:8545) (called "Localhost 8545" in MetaMask).
- You can configure that local Nile node by editing the files in the `barge/networks/nile/config/` directory.

## A Spree Testnet
When Ocean Protocol developers run [Barge](https://github.com/oceanprotocol/barge) with the `--local-spree-node` option, a "Spree Testnet" node is deployed on their local machine: a local "testnet" not connected to any public testnet. It's named after the main river flowing through Berlin, Germany, where many Ocean Protocol developers are located.

Spree testnet details can be found in the [Barge README.md file](https://github.com/oceanprotocol/barge/blob/develop/README.md).
Spree Testnet details can be found in the [Barge README.md file](https://github.com/oceanprotocol/barge/blob/develop/README.md).
You can configure the Spree nodes by editing the files in the `barge/networks/spree/` directory.
Note: Spree testnets are named after the Spree River, the main river flowing through Berlin, Germany, where many Ocean Protocol developers are located.
