Set Up MetaMask

How to set up a MetaMask wallet on Chrome

Before you can publish or purchase assets, you will need a crypto wallet. As Metamask is one of the most popular crypto wallets around, we made a tutorial to show you how to get started with Metamask to use Ocean's tech.

MetaMask can be connected with a TREZOR or Ledger hardware wallet but we don't cover those options below; see the MetaMask documentation.

Set up

1. Go to the Chrome Web Store for extensions and search for MetaMask.

metamask-chrome-store

• Install MetaMask. The wallet provides a friendly user interface that will help you through each step. MetaMask gives you two options: importing an existing wallet or creating a new one. Choose to Create a Wallet:

Create a wallet

• In the next step create a new password for your wallet. Read through and accept the terms and conditions. After that, MetaMask will generate Secret Backup Phrase for you. Write it down and store it in a safe place.

• Continue forward. On the next page, MetaMask will ask you to confirm the backup phrase. Select the words in the correct sequence:

Confirm secret backup phrase

• Voila! Your account is now created. You can access MetaMask via the browser extension in the top right corner of your browser.

• You can now manage ETH and OCEAN with your wallet. You can copy your account address to the clipboard from the options. When you want someone to send ETH or OCEAN to you, you will have to give them that address. It's not a secret.

Set Up Custom Network

Sometimes it is required to use custom or external networks in MetaMask. We can add a new one through MetaMask's Settings.

Open the Settings menu and find the Networks option. When you open it, you'll be able to see all available networks your MetaMask wallet currently use. Click the Add Network button.

Add custom/external network

There are a few empty inputs we need to fill in:

• Network Name: this is the name that MetaMask is going to use to differentiate your network from the rest.

• New RPC URL: to operate with a network we need an endpoint (RPC). This can be a public or private URL.

• Chain Id: each chain has an Id

• Currency Symbol: it's the currency symbol MetaMask uses for your network

• Block Explorer URL: MetaMask uses this to provide a direct link to the network block explorer when a new transaction happens

When all the inputs are filled just click Save. MetaMask will automatically switch to the new network.
