Although a new space, dapps (decentralized applications) are growing in number and many now exist in various industries, such as media, education, wallet, browser, infrastructure platforms, and more.

In particular, the gaming industry has been growing tremendously - Gods Unchained, Fomo3D, CryptoKitties… You find yourself can’t avoid getting into the conversation that is sweeping the world. However, there’s one problem: these games aren’t exactly pick-up-and-go. The steep learning curve has prevented many people from trying out dapps.

But hey, dapps are not designed only for tech-savvy person. In this article, we will take crypto gaming as an example and walk you through the steps of using a dapp that is based on the Ethereum blockchain.


For EOS dapp, check out here for a quick tutorial. 


If you’re just starting out in the crypto space at the point of “I know what blockchain is about and I just want to be one of the first explorers of dapps”, this article is ideal for you.


3 Ethereum Terms You Should Know

If you are just getting into the crypto world, there are few terms that might have confused you:

  • MetaMask - MetaMask is a wallet that allows users to interact with the Ethereum network. It enables users to sign smart contracts, buy, store and send ETH as well as ERC20 tokens.

  • ERC-721 token - all of your crypto collectibles are ERC-721 tokens!

  • Gas - Gas is a measurement roughly equivalent to computational steps. Every transaction includes a gas limit and a price that you are willing to pay per gas. Setting a higher gas price will make your transaction faster.


To Set Up:

Step1. Download MetaMask extension

To use any dapps that are based on the Ethereum blockchain, you’re going to need the MetaMask extension in your browser.

  • Install MetaMask: Click “Add to Chrome” to install MetaMask as Google Chrome extension.

  • Click “Add Extension” to confirm and MetaMask will be added


You will see that MetaMask is added by the little fox logo that shows up on the top right corner.


Step 2: Create a wallet

Click on the MetaMask logo, then click “Create New Vault”. Enter a password and click “OK”

  • MetaMask will show you your seed. It’s essential for you to copy and carefully store these 12 words, without them, you cannot restore your wallet.


Step 3: Import ERC20 address / Create a new account & Buy some ETH

If you previously have ERC20 addresses, open the account menu (the person image) in the top right and click “Import Account”.

Or you can create a new one by clicking “Create Account”. Purchasing Ethereum can be done easily at Ethereum exchanges such as Binance, Coinbase, and so on.

Now you have everything equipped to start playing a dapp!


Start Playing Dapps

Choose a game that caught your eye and click “Visit Website”. Sign up for the game to start playing.

Some games such as 0xUniverse use ETH as their transaction currency. If you want to own a crypto planet, click the “Buy” button, your MetaMask wallet will automatically pop up the “Transaction Confirmation” window. Click “Submit” to seal the deal.

Other games, however, have their own token and wallet as their official currencies. Take Fair City, the first crypto slot game in the world, as an example.


Step 1. Open your wallet at the game center. Click “Deposit” to transfer ETH from your Metamask wallet to the wallet in the game.

Step 2. Click “Copy Address”

Step 3. Open MetaMask, click “Send”. Paste the address, enter the amount of ETH you want to transfer, then click “Next”

Step 4. Confirm the transaction

Step 5. Exchange ETH to token (in this case, FAIR)
