The quickest way is to press “Buy ETH” on the home screen of your wallet. Ok, now that you have a sense of what is out there, load up your wallet with some ETH. To hold BTC and ERC-20 coins together, try out a multi-chain wallet like Liquality. ? You won’t be able to buy Bitcoin (BTC) through MetaMask, as MetaMask is an Ethereum Wallet that hosts strictly ERC-20 assets.
You’ll notice that the majority of tokens in the top 100 are ERC-20s and are supported by MetaMask. It’s a handy site that ranks cryptocurrencies and tokens by their market cap and presents useful information about each project. What’s the best way to see what tokens are out there? Use your MetaMask browser to visit CoinGecko. The other major category of tokens that MetaMask supports is ERC-721 tokens, also known as NFTs, which can represent unique digital items, such as art, tickets, badges, game items, and so on. MetaMask also supports every type of ERC-20 token, including stablecoins, such as USDT, USDC, and DAI, and other types of utility tokens that may be used for governance. If you want to do anything that involves smart contracts on Ethereum, you’ll need to buy some ETH. One of the foundational aspects of Ethereum is ether, or ETH, which is the fuel you pay to use the Ethereum tokens. ? # of contracts – 6.7k Manage your digital assets Into other dApps? You have many others to choose from visit State of the Dapps for a comprehensive list. It also makes it easy to browse between different applications without creating a new account each time. This means you are always browsing privately and control the data you share with an application. Notice how when you visit a Web3 site, you can connect your MetaMask account? MetaMask will never share your public address with a website unless you give it permission. In this gif, I’m checking out NFT art on OpenSea, a peer-to-peer marketplace for rare digital items, game items, art, and collectibles. ? You don’t need cryptocurrency to begin browsing Web3.
Type in the name of the website that you want to visit in the search bar. Seems familiar, right? MetaMask Mobile contains a powerful browser like the ones you use every day, except this one can also access decentralized applications (dApps). From this page, tap the hamburger menu icon on the screen’s left-hand side and click on Browser. Now it’s time to explore the decentralized web. Test it out by acquiring test tokens at a “ faucet.” We will stick with the Ethereum Main Network for this exercise, where the majority of value on Ethereum transacts. These test networks are meant to ease development, allowing developers to test their products, or sometimes, for users to test out applications. Under “Wallet,” you’ll also notice that you can choose between the Ropsten Test Network, Kovan Test Network, Rinkeby Test Network, and Goerli Test Network.
The default home screen will automatically be the Ethereum Main Network, which is what most applications use. Once you’re in, you will see a balance of your ERC-20 and ERC 721 tokens.
Import your wallet from your seed phrase (which, if you followed our advice, is stored in your password manager, on a piece of paper hidden away, or even on a Seed Wallet).
If you are downloading from the MetaMask website, be sure to type MetaMask.io in your browser’s address bar.ĭownload and install the app.
Head to the App Store, Google Play, or the MetaMask website to download MetaMask.
In Ethereum the chosen parameters are those of the “secp256k1” standard curve and are given in this PDF of “Standards for Efficient Cryptography”.Not only does MetaMask offer a non-custodial wallet that holds your Ethereum based assets, but it allows you to peruse thousands of decentralized applications. This type of cryptography relies first on the choice of some mathematical field (parametrized by three values h, p and n), some elliptic curve (parametrized by two values a and b) and some point g = (x,y). The cryptographic standard used by Ethereum (which is the same as the one used by Bitcoin) is based on Elliplic Curve Cryptography. The creation of these keys will be the starting point of the first part of this tutorial. Since the Ethereum blockchain is based on asymmetric cryptography, this means that the wallet should at least be able to generate and store public and private keys. An Ethereum wallet is simply a specific set of cryptographic keys together with methods that allow an user to interact with the blockchain by sending and receiving tokens using these keys.
