  • Learn how to sign transactions, buy .eth domains, encrypt messages and exchange tokens.

For those interested in learning how to use Ethereum, CriptoNoticias offers this collection of video tutorials. Through these it is possible to know the necessary steps to perform transactions with ethers (ETH), and take advantage of many of the functions available on the platform.

The information in these videos is useful for learning how to buy and sell digital currency, as well as where to manage public and private keys, while leveraging smart contract technology. It also shows how to use several of the decentralized applications (dApps) available on the network and interact with the Ethereum blockchain.

Buy and sell ETH at LocalEthereum

One of the most used platforms for ETH exchange is LocalEthereum, a P2P (person-to-person) exchange site with a presence in more than 100 countries. and LocalEthereum the exchange is carried out through the implementation of smart contracts, One of the main features that differentiates Ethereum from other platforms.

In these smart contracts the exchange guidelines are established and with this it is achieved that the funds are released only when the two parties reach a mutual agreement. In addition, the public is offered independent handling of money, as the private key will be stored only by the user.

In this way, the tutorial explains, step by step, how to register on the portal and how to use the two mechanisms by which you can start making transactions on the platform: posting an ad or making a direct purchase from a seller.

Learn how to use Ethereum with Metamask

Metamask is a portfolio that works as an extension or connector in Chrome, Brave and Firefox browsers. Provides access to Ethereum network services. With its use, transactions and payments can be made, in addition to signing or executing smart contracts, among other functions.

According to figures from the Metamask team, the extension recorded a weekly growth of approximately 1.1% in its number of users, with a total average of 192,000 active customers monthly. It also works like a traditional wallet where you can manage public and private keys, as well as send and receive, without neglecting the necessary security mechanisms.

In this sense, the tool owns a database of malicious sites they seek to obtain users’ passwords and steal their funds. It makes it easy to run decentralized Ethereum applications in the browser, without having to run a full node. These applications have an architecture that requires internal payments in order to perform different activities, either buying a kitten or creating a symbol.

The following CriptoNoticias tutorial shows how to use Metamask in its basic form: as a wallet, to create multiple accounts, export the private key, and use decentralized applications like CryptoKitties, Aragon, and TokenFactory.

Create and buy CryptoKitties

Once trained in handling Metamask, it is possible to use Cryptokitties, one of the most famous dApps to date. It is a game where you can collect “digital kittens”, which, depending on their rarity, generation or attributes have more or less value.

These digital kittens can also be bred and paired in order to generate new cryptocurrencies, which inherit the characteristics of their predecessors. All these factors influence its final price. Bye now, the most expensive kitten in the game is Dragon, Sold at 600 ethers, an amount equivalent to more than USD 172,000 at the time of the sale, in September 2018.

each kitten is an indivisible symbol of Ethereum (ERC721). Therefore, for the purchase, sale, or any other operation, a network transaction must be executed, which involves a mining expense or fee. The following tutorial explains, in detail, the procedure for creating an account on the Cryptokitties portal.

Interact with the Ethereum blockchain with MyCrypto

MyCrypto is an interface that allows you to learn how to use Ethereum in a particular way. The goal is for the public to be able to manage the funds, either in ETH or any other symbol that works under the network’s smart contracts. too makes it easy to sign transactions, buy domains .eth, In addition to encrypting messages, Exchange tokens (via ShapeShift) or use the MetaMask wallet.

The first version was released to the public in February 2018. In July of that year, version 1.2.0 was released, with updates to the desktop application. Subsequent updates removed the option to generate wallets in the browser, so you need to download the app to be able to create addresses. This seeks to provide more security to the user, as the key key information is not entered into the Internet.

However, from the portal it is possible to interact with Metamask, Trezor or Ledger directly. Although MyCrypto can be used directly from the website, when entering private keys on the platform, which, for security reasons, is not recommended.

The CriptoNoticias tutorial describes how to download the Ethereum portfolio from MyCrypto and teaches you how to manage private keys from the different tools provided by the platform, while taking advantage of its main features.
