Installing and setting up MetaMask
MetaMask can be downloaded on Chrome and Firefox, or on iOS and Android if you’re a mobile user. For the purposes of this tutorial, we’ll use the Firefox version, but the instructions will be more or less the same for every platform.
Firstly, you’ll want to head over to the MetaMask Download page. From there, select whichever platform you’re using, and follow the steps to install it on your device. Easy!
Next, follow along with the setup specified by the app. Go ahead and click Create a Wallet. Write down the backup seed phrase somewhere secret (preferably not on an Internet-connected device). Without this phrase, your funds can’t be recovered if your device is damaged or lost. Confirm that you’ve written them down on the next page.
And that’s it! You should now see your wallet, ready to send and receive funds.

Configuring the wallet
You might notice straight away that we’re still dealing with an Ethereum wallet. At best, this won’t work with 1COIN Smart Chain DApps. At worst, you could lose funds by sending them to addresses you can’t actually use.

On the Settings page, we want to locate the Networks menu.

We want to click Add Network in the top-right corner to manually add the 1COIN Network – it doesn’t come packaged with MetaMask. Below are the parameters to fill in for each.
1COIN Mainnet
Network Name: 1COIN Network
New RPC URL: https://data.1coin.network/
ChainID: 85
Symbol: 1CN
Block Explorer URL: https://1coin.network
Once you Save the Network and return to the main view, you’ll notice two things: the network has automatically been set to the one you just entered, and the units are no longer denominated in ETH, but in 1CN.

Closing thoughts
MetaMask has long been the go-to passport for accessing the sprawling Ethereum landscape. But, with minimal effort, anyone can configure it to point towards 1COIN Smart Chain Network. This allows them to enjoy years of development put into making MetaMask an indispensable tool for anyone interacting with decentralized applications.
