The next page asks whether you want to submit anonymized data to help the devs improve the app. Pick whichever option you prefer. Now we need to create a password. Otherwise, come up with a strong password, tick the box, and hit Create. The following point is enough to warrant its own subheading. MetaMask is a non-custodia l service, meaning that no one else can access your funds — not even the MetaMask developers.
Your tokens exist in a sort of encrypted vault within your browser, protected by your password. That means that if your computer is lost, stolen, or destroyed, nobody can help you recover the wallet. Your private keys will be forever lost in the void of cyberspace. This is the only way you can restore your account should something unfortunate happen. As suggested, we recommend that you write the words down and store them in two or three different locations.
When you get to the next page, the program anticipates that you may have been lazy with the previous step, because it asks you to confirm the phrase. Confirm the phrase, then proceed to the next step. Every step we perform on this network today will be replicable on the real thing except for the part where they gift us free ether, unfortunately.
Navigate to this page on your Metamask-enabled browser to get some. Hover over Account 1 , and click to copy your Ethereum address to the clipboard. Paste it into the form and hit Send me test Ether. For a comprehensive list of mainnet decentralized applications, check out State of the DApps or Dappradar.
You can play games , buy one-of-a-kind assets , or place bets on prediction markets. Uniswap is a decentralized exchange, or DEX, meaning that it allows us to place trades without relying on intermediaries. Go ahead and access it here. In the top right-hand corner, you should see a prompt to Connect to a wallet.
The level of privacy you want to achieve ultimately depends on you. Time to make our first swap. Just like our ether, though, this DAI has no real-world value. Alternatively, you could also pick WETH wrapped ether. Hit Swap. Buy ETH on Binance! For more popular tokens, you can select Add Token in your wallet and search for the name or ticker. For the less popular ones or those on the testnet , we need to add the contract address — an identifier that tells MetaMask where to look for our balance.
You can also connect a hardware wallet Trezor and Ledger are both supported , create a contact list, and, of course, receive and send funds as you would in a normal wallet. Check out the settings to customize the extension to suit your needs. Other than that, the usual security principles apply: MetaMask is a hot wallet , meaning that it runs on an internet-connected device.
This exposes you to more risk than a cold wallet, which is kept offline to reduce attack vectors. The main use case for the Ethereum blockchain has so far been the exchange of digital tokens. The most popular ERC smart contract by transaction count is 0xc8cf97bead5deaeff8e7ad , the main smart contract for the CryptoKitties game. You can query the logs table for instances of this event here. We can visualize the CryptoKitty pedigree, as shown here for accounts that own at least 10 CryptoKitties.
Color indicates owner, while size indicates the PageRank reproductive fitness of each CryptoKitty:. There are many types of tokens being distributed on the Ethereum blockchain, and their patterns of distribution vary by type and also by time. Find the answer here. Because the data, at a highly granular level, consists of a set of transfers between wallet addresses, we can also reason about the data using a directed graph data structure. We mentioned previously that many of the smart contracts on the Ethereum blockchain are ERC contracts.
What does this mean? ERC simply defines a software interface that smart contracts can implement. There are many other functions that can be implemented by a smart contract. Coming back to the CryptoKitties, discussed in Analysis 3 above, the major element of gameplay is animal husbandry, and the mixing of genes in a breeding event is implemented in the CryptoKitties GeneScience smart contract, 0xf97e0a5bdffcefde9ea8bbea2b.
Suppose we wanted to find other games also implementing similar gameplay mechanics to the CryptoKitties GeneScience contract? These results reveal that several earlier versions of the GeneScience contract are most similar to the current version of the smart contract at address 0xf97e0a5bdffcefde9ea8bbea2b. But there are also some others e. CryptoPuppies at 0xb64e6befa0d3eac80b5ecbfaeb6 , that appear to be highly similar contracts, as measured by method signatures.
