This document describes how you can use a wallet in MetaMask to connect to Switchboard. After completing the steps described in this document, you can use Switchboard.
1 I. Install the MetaMask browser extension
MetaMask is an extension for accessing Ethereum-based decentralized applications, including Switchboard. The MetaMask extension is available only for Chrome and Firefox.
Install the MetaMask browser extension via your browser’s web store or https://metamask.io.
After installing MetaMask, you may see the image below on your screen. If not, click on the MetaMask extension icon (orange fox) in your browser.
Click “Get Started.”
This document assumes that you do not already have a wallet you would like to use. If you have one, you may import it into MetaMask using the “import wallet” option. After you do this, skip to Step 3.
To create a new wallet, click the “create a wallet” button.
Create a new password and agree to the terms of use.
At this point, you should see the screen at right. Click the gray box with the text, “CLICK HERE TO REVEAL SECRET WORDS.”
It is very important to copy these words—in the exact order—and store them in a safe place. If you lose or forget this “seed phrase,” it is not possible to recover it.
On the next screen, MetaMask will check that you have copied your seed phrase this by asking you to confirm it.
You now have a wallet in MetaMask.
Switchboard can be used on Volta or the Energy Web Chain (EWC). You can connect your MetaMask account to either one.
Because Volta tokens are freely available from the faucet and have no value, we recommend testing Switchboard on Volta.
To connect to Volta, first click on the MetaMask browser extension. At the top of the element that appears, click on the pull-down menu, “Main Ethereum Network” (it should appear similar to the top of the image at right). In the gray box, click on the bottom option, “Custom RPC.”
Next, enter the network information shown in the image below. For your convenience, you can copy these URLs:
New RPC URL: https://volta-rpc.energyweb.org
Block explorer URL (optional): http://volta-explorer.energyweb.org/
After you do this, your MetaMask extension should appear similar to the image at right.
Note that if you hover your mouse pointer over the words “Account 1” at the top center of the extension window, you will have the option to copy your address (public key).
You now have created a key pair in MetaMask and can connect it to Switchboard.
To connect to the EWC, first click on the MetaMask browser extension. At the top of the element that appears, click on the pull-down menu, “Main Ethereum Network” (it should appear similar to the top of the image at right). In the gray box, click on the bottom option, “Custom RPC.”
Next, enter the network information shown in the image below. For your convenience, you can copy these URLs:
New RPC URL: https://rpc.energyweb.org
Block explorer URL (optional): http://explorer.energyweb.org/
After you do this, your MetaMask extension should appear similar to the image at right.
Note that if you hover your mouse pointer over the words “Account 1” at the top center of the extension window, you will have the option to copy your address (public key).
You now have created a key pair in MetaMask and can connect it to Switchboard.
