Install and Use MetaMask Wallet for Ethereum Decentralized Applications

Decentralized applications (dapps) built on the Ethereum blockchain allow for a new paradigm of software that does not rely on centralized servers. To interact with these dapps, users need an Ethereum wallet. MetaMask is one of the most popular and easy to use Ethereum wallets available. With just a few clicks, anyone can install MetaMask as a browser extension and start using dapps on the Ethereum network.

Getting Started with MetaMask

To get started with MetaMask, first visit the MetaMask website and download the browser extension for Chrome, Firefox, Brave or Edge. The installation process takes just a minute. Once installed, MetaMask will prompt you to create a new wallet or import an existing one if you already have Ethereum accounts.

When creating a new wallet, MetaMask generates a 12 word seed phrase that serves as your private key. This phrase gives you access to your accounts, so be sure to store it securely. Never share your seed phrase with anyone.

After setting up your wallet, MetaMask provides you with a public Ethereum address to receive funds and interact with dapps. Make sure to copy this address to receive any ETH you buy from an exchange or wallet.

Funding Your MetaMask Wallet

To use dapps on Ethereum, you'll need to fund your MetaMask wallet with ETH. Here are some ways to get ETH into MetaMask:

  • Buy ETH on an exchange like Coinbase or Binance, then withdraw it to your MetaMask address.
  • Use a service like Wyre or Transak to purchase ETH directly into your MetaMask wallet.
  • Transfer ETH from another wallet you own into your MetaMask address.
  • Earn ETH rewards from protocols like Uniswap or MakerDAO and transfer them to MetaMask.

I recommend always keeping a small amount of ETH in your MetaMask wallet to cover gas fees on the Ethereum network. Gas fees fund the transactions you submit and vary based on network congestion.

Connecting MetaMask to Decentralized Applications

Once your MetaMask wallet is funded, you're ready to start interacting with dapps! Here's how to connect MetaMask to decentralized apps:

  1. Navigate to the dapp website you want to use. Many popular dapps include Uniswap, MakerDAO, Compound, Aave, and more.
  2. Click the "Connect Wallet" button. This allows the dapp to connect with your MetaMask account.
  3. A popup will appear from the MetaMask browser extension asking you to confirm the connection.
  4. Click "Next" then "Connect" to approve the dapp connection.

Now the dapp can pull up your wallet balance, enable transactions, and more! Always verify you're on the legitimate site before connecting your wallet.

Key Benefits of MetaMask

There are many reasons why MetaMask has become the most trusted crypto wallet for dapps:

"Once I started using MetaMask, the entire Ethereum dapp ecosystem opened up to me. I can't imagine accessing DeFi or NFT platforms without it!"

Now that you're set up with MetaMask, you have the keys to unlock a whole new world of dapps. You'll quickly find it becomes an indispensable part of your crypto portfolio.

Decentralized finance (DeFi) applications like Uniswap, Aave and Compound top the list for most active dapps used with MetaMask today. Here are just a few to explore:

  • Uniswap - Leading decentralized exchange to trade ETH and ERC-20 tokens.
  • MakerDAO - Lend and borrow DAI stablecoins with over-collateralized vaults.
  • Aave - Earn interest by lending assets or borrow against collateral.
  • Compound - Algorithmic money markets where you can lend and borrow tokens.
  • Balancer - Earn fees by supplying liquidity to customizable token pools.
  • Synthetix - Trade synthetic assets tracking real-world assets like gold and stocks.

Beyond DeFi, MetaMask enables access to NFT markets, DAOs, games and more!

How do you switch Ethereum networks in MetaMask?

One powerful feature of MetaMask is the ability to switch between different Ethereum networks. Here's how to change networks:

  • Open the MetaMask browser extension or mobile app
  • Click your account icon in the upper right corner
  • Select "Settings"
  • Click "Networks"

Choose the Ethereum network you want to connect to:

  • The Main Ethereum network where dapps transact with real ETH
  • Test networks like Ropsten and Rinkeby for testing
  • Layer 2 networks like Optimistic Ethereum and Arbitrum
  • Other EVM compatible chains like Polygon, Binance Smart Chain, etc.

After selecting a new network, MetaMask will reconnect without disrupting your accounts and activity. This allows you to seamlessly switch between public Ethereum, layer 2 scaling solutions, testnets, and more.


Installing and setting up MetaMask wallet opens the door to the exciting world of dapps on Ethereum. With just a seed phrase, you gain secure access to DeFi, NFTs, DAOs, and more. MetaMask makes blockchain interactions easy for dapp newbies and experienced crypto users alike. Now equipped with your own MetaMask wallet, go explore all the amazing use cases Ethereum has to offer!
