Qtum

Welcome back to the second installment of our detailed guide on the Qtum Web Wallet.In the first part, we embarked on a journey to understand the basics of the Qtum Web Wallet, from creating and restoring wallets to executing transactions with QTUM coins.We also explored advanced functionalities such as using a Ledger and the Safe Send feature, adding an additional security layer to your transactions.As we continue our exploration, we will go deeper into the advanced features of the Qtum Web Wallet.We&#39;ll guide you through expanding your digital asset portfolio with QRC20 tokens, publishing smart contracts, delegating addresses for offline staking, and even creating and sending Non-Fungible Tokens (NFTs).Whether you&#39;re a seasoned blockchain enthusiast or a newcomer to the world of digital assets, this comprehensive guide will provide you with the necessary tools and knowledge to navigate the Qtum ecosystem confidently.We&#39;ll explore the intricacies of the Qtum Web Wallet, shedding light on its features and how you can leverage them to maximize your interaction with the Qtum blockchain.<h2 id="header-0">QRC20 Tokens</h2>In the dynamic world of digital assets, diversity is key. That&#39;s where QRC20 tokens come into play.These tokens, similar to Ethereum&#39;s ERC20 tokens, are a crucial part of the Qtum ecosystem, allowing for creation of new digital assets on the Qtum blockchain.Your Qtum Web Wallet can handle these tokens too.<h2 id="header-1">Understanding QRC20 Tokens</h2>QRC20 tokens are a type of digital asset created on the Qtum blockchain.Developers can create their own tokens, each with its unique functionalities, and distribute them to users.These tokens can represent anything from company shares to access tokens for a specific service.<h2 id="header-2">How to Receive and Send QRC20 Tokens</h2>To receive QRC20 tokens, you need to copy your Qtum Web Wallet address.<ol><li>You can do this by going to the &#34;View Wallet Info&#34; page and clicking on the blue &#34;COPY&#34; button next to your address.</li><li>Paste this address into the sending wallet or exchange, and send the tokens.</li><li>After the next block is published, reload your wallet to see the received tokens.</li></ol><img src="https://academy-public.coinmarketcap.com/optimized-uploads/ee0f510314a84168a4830c2bf938b44a.png" />To send QRC20 tokens, the Qtum address to which they were deposited must maintain a balance greater than 0 to cover the necessary gas fees. The wallet will automatically calculate this fee for you, which typically amounts to just a few pennies.<ol><li>From the web wallet menu, select &#34;Send&#34; In the drop-down menu next to &#34;QTUM&#34; select the QRC20 token you want to send.</li><li>Fill in the recipient&#39;s address and the amount of tokens you wish to send, then click the &#34;CONFIRM&#34; button.</li><li>After verifying the information, click the &#34;CONFIRM&#34; button again to send the tokens.</li></ol><img src="https://academy-public.coinmarketcap.com/optimized-uploads/314e2808ddf640fb8daa40e7178bb228.png" /><h3 id="why-add-new-qrc20-tokens">Why Add New QRC20 Tokens?</h3>QRC20 tokens are similar to ERC20 tokens in that they allow any developer to deploy their project on the Qtum blockchain. To gain access to these projects, all you need is a Qtum wallet with a small amount of gas.Adding a QRC20 TokenThe web wallet has built-in capability for QRC20 tokens, and you can add additional tokens by entering the token&#39;s smart contract information.<ol><li>Find the token on the Explorer qtum.info, copy the contract Address Hash field.</li></ol><img src="https://academy-public.coinmarketcap.com/optimized-uploads/f52c29114e83479ab52417f60dd7e389.png" />2.

The same goes for Qtum.But, NFTs, which are short for non-fungible tokens, are different. They are unique, which means every NFT is different from the other.Each NFT stands for owning a particular thing or a piece of information.Unlike Bitcoin or Qtum, NFTs can&#39;t be broken into smaller parts. If you have an NFT, it stays as one whole thing. Just 1 NFT.This uniqueness has led to their rising popularity, especially in digital art, collectibles, and virtual real estate.The Qtum Web Wallet offers a user-friendly platform for creating and sending NFTs. Here&#39;s a general guide on how to do it:Creating NFTs: To create an NFT, select the &#34;Create NFT&#34; option in the menu.This will open a form where you can fill in the details of your NFT.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/1658790a4b92452b96e9a1b2216f5ea2.png" />You can upload an image or animation (in specific formats) as the content of your NFT.You can also provide a name and description for your NFT, and specify the number of tokens you want to create (between 1 and 10).The wallet must hold QTUM to pay the fees, which is 1.01 QTUM per NFT minting.Sending NFTs: To send an NFT, go to the &#34;View Wallet Info&#34; form and click on the &#34;SEND&#34; button for the NFT you want to send.<img src="https://academy-public.coinmarketcap.com/optimized-uploads/73f2bf47b0644f83a7980fbd64152632.png" />You then need to fill out the “send NFT” form with the address and quantity of the NFTs you want to send.After confirming the information, click the &#34;CONFIRM&#34; button to send the transaction.Receiving NFTs: The &#34;View Wallet Info&#34; menu option will show any NFTs minted or received by the wallet.You can click on the thumbnail of an NFT to see a larger image of it.The quantity of each NFT you have is shown in the upper right-hand corner of the thumbnail.Please note that the exact steps and requirements may vary depending on the specific features and updates of the Qtum Web Wallet.The Qtum Web Wallet is a powerful tool that opens up a world of possibilities in the realm of digital assets and blockchain technology.From creating and restoring wallets, executing transactions, and publishing smart contracts, to creating and sending NFTs, the Qtum Web Wallet is designed to make these processes as seamless and intuitive as possible.So why wait?
