## Connect to the Pacific Network
##Connect to Ethereum mainnet
Here are the parameters you might need to connect to the [Pacific Network](/concepts/pacific-network/):
Metamask and other ERC20 wallets default to Ethereum mainnet. Therefore your wallet is almost certainly pointing to Ethereum by default.
| Parameter | Value |
| ------------------ | ---------------------------------------------------------- |
| RPC URL (required) | `https://pacific.oceanprotocol.com` |
| ChainID | `846353` (decimal for MetaMask) or `0xcea11` (hexadecimal) |
| Symbol | Whatever you like, e.g. `PACIFIC ETH` |
| Nickname | Whatever you like, e.g. `Pacific` |
Some apps may need `network_id` and `chain_id`. The values are both `1` for Ethereum mainnet. `Symbol` and `nickname` can be whatever value you like.
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](https://metamask.github.io/metamask-docs/Main_Concepts/Sending_Transactions).
##Connect to Ropsten testnet
If you're using [Barge](https://github.com/oceanprotocol/barge) to run a local Pacific node, you can connect to that local Pacific node at RPC URL [http://localhost:8545](http://localhost:8545) (called "Localhost 8545" in MetaMask). You can configure that local Pacific node by editing the files in the `barge/networks/pacific/config/` directory.
In MetaMask, click on the network name dropdown, then select `Ropsten`.
## Connect to the Nile Testnet
Its `network_id` is 3 and `chain_id` is 3.
Here are the parameters you might need to connect to the [Nile Testnet](/concepts/testnets/#the-nile-testnet):
##Connect to local Ganache network
| Parameter | Value |
| ------------------ | ------------------------------------------------------- |
| RPC URL (required) | `https://nile.dev-ocean.com` |
| ChainID | `8995` (decimal for MetaMask) or `0x2323` (hexadecimal) |
| Symbol | Whatever you like, e.g. `NILE ETH` |
| Nickname | Whatever you like, e.g. `Nile Testnet` |
**Metamask.** 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](https://metamask.github.io/metamask-docs/Main_Concepts/Sending_Transactions).

**Barge.** If you're using Ocean [Barge](https://github.com/oceanprotocol/barge) to help run a local network, you can connect to that local node at RPC URL [http://localhost:8545](http://localhost:8545) (called "Localhost 8545" in MetaMask). You can configure that local node by editing the files in the `barge/networks/pacific/config/` directory.
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.

## Connect to a Local Spree Testnet or Ganache-Based Testnet
When using [Barge](https://github.com/oceanprotocol/barge) to run a purely-local testnet (Spree or Ganache-based), you can connect to a local node at RPC URL [http://localhost:8545](http://localhost:8545) (called _Localhost 8545_ in MetaMask).
