Connect to Ocean-Related Networks

How to connect to the Kovan testnet, Nile testnet and other Ocean-related networks.

Connect to the Kovan Testnet

Most Ethereum wallets and libraries know how to connect to the Kovan Testnet. In MetaMask, click on the network name then click on “Kovan Test Network” in the drop-down list.

If you’re using Barge to run a local Kovan node, you can connect to that local Kovan node at RPC URL http://localhost:8545 (called “Localhost 8545” in MetaMask).

Connect to the Nile Testnet

Here are the parameters you might need to connect to the Nile Testnet:

ParameterValue
RPC URL (required)https://nile.dev-ocean.com/
ChainID8995 (decimal for MetaMask) or 0x2323 (hexadecimal)
SymbolWhatever you like, e.g. NILE ETH
NicknameWhatever you like, e.g. Nile Testnet

In MetaMask, click on the network name then click on Custom RPC in the drop-down list. Scroll down to the New Network section. Enter the above RPC URL. You don’t need to add a port number to the end of the RPC URL. Enter the ChainID, Symbol and Nickname if you like. See the MetaMask docs about how it uses the ChainID.

If you’re using Barge to run a local Nile node, you can connect to that local Nile node at RPC URL 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.

Connect to a Local Spree Testnet or Ganache-Based Testnet

When using Barge to run a purely-local testnet (Spree or Ganache-based), you can connect to a local node at RPC URL http://localhost:8545 (called “Localhost 8545” in MetaMask).
