One of the most widely used ETH exchange platforms is LocalEthereum, a P2P (person-to-person) exchange site that is present in more than 100 countries. On LocalEthereum the exchange takes place through the implementation of smart contractsone of the main features that differentiates Ethereum from other platforms.

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

Learn how to use Ethereum with Metamask

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

According to data from the Metamask team, the extension recorded an approximate weekly increase in the number of users of 1.1% with total average of 192,000 active clients monthly. It also works as a traditional wallet where you can manage public and private keys, as well as send and receive, without leaving aside the necessary security mechanisms.

It makes it easy to run decentralized Ethereum applications in the browser, without the need to run a full node. These apps have an architecture that requires internal payments to perform various activities, be it buying kittens or creating tokens.

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

Breed and buy CryptoKitties

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

These digital kittens can also be bred and mated to create new cryptokittens, which inherit the characteristics of their predecessors. All these factors affect its final price. So far, the most expensive kitten in the game is Dragon, sold for 600 etheran amount equivalent to more than $172,000 at the time of sale, in September 2018.

Everyone’s a kitten is an Ethereum indivisible token (ERC721). Therefore, to buy, sell or any other operation, the transaction must be done online, which implies a mining cost or fee. The next one tutorial explains in detail the procedure for creating an account on the Cryptokitties portal.

Interacting with the Ethereum blockchain using MyCrypto

MyCrypto It is an interface that allows you to learn how to use Ethereum in a certain way. The goal is for the public to be able to manage funds, whether in ETH or any other token that operates under the network’s smart contracts. Also makes it easy to sign transactions, buy .eth domains, and encrypt messagesexchange tokens (via ShapeShift) or use a MetaMask wallet.

The first version was released to the public in February 2018. In July of the same year, version 1.2.0 was released, with updates to the desktop application. Subsequent updates removed the option to generate a portfolio in the explorer, so To create addresses, you need to download the application.
