INTUITIVE DESIGN INTEGRATION AND DEVELOPMENT OF SMART CONTRACTS MULTIPLATFORM COMPATIBILITY [Book a meeting](/en/meeting) A decentralized application (DApp) is a program whose business logic runs in smart contracts on a blockchain instead of on a server controlled by a single entity. Users interact with it through their wallet. Unknown Gravity builds complete DApps, from the contract to the interface. **We create tailor-made blockchain solutions that improve the security, transparency and autonomy of your processes** ## 01 / Create a dApp on Ethereum or any EVM **DApps and blockchain technology are changing the rules of the game.** It's not just a matter of technology, it's a matter of control. We are talking about applications that eliminate intermediaries, increase security and offer you transparency, which should already be a standard. Forget about systems that tie you to third parties and unnecessary processes. ## 02 / What are decentralized applications and what are they for? DApps (Decentralized applications) are applications whose characteristic is to have a user interface to interact with the blockchain, improving the user experience. For this reason, dApps are transforming many industries as they offer a wide range of uses: ### **Financial sector** Allowing transactions to be carried out without intermediaries and reducing operating costs. For example, Uniswap, a decentralized exchange platform that allows its users to exchange Ethereum tokens directly with each other. Replicating a decentralized exchange aimed at EU users may require authorization as a crypto-asset service provider (Regulation (EU) 2023/1114, whose Spanish transitional regime expired on 1 July 2026). ### **Video game industry** Obviously blockchain was also going to reach this sector, through the creation of dApps, it was possible for players to own and trade digital assets. An example of this could be Mythical Beings, a collectible NFT card game, in which you can buy, sell and exchange your cards. ### **Voting systems** DApp applications have gone so far as to ensure that you can vote safely, preventing your personal data from falling into unwanted hands or being made public and managing to keep a detailed account of them. ## 03 / What are the benefits of developing dApps? The development of dApps offers important advantages that make them stand out from traditional applications: - **Elimination of intermediaries.**Thanks to the decentralization of dApps, it won't be necessary to depend on anyone for something to work. You don't depend on a central server or middlemen who can slow down your operations. This results in greater control over your data and efficiency in your processes. - **Data protection.**When operating on a blockchain network, identity rests on cryptography rather than on the name or postal address of the user. But a wallet address is pseudonymized personal data and remains subject to the GDPR (recital 26 of Regulation (EU) 2016/679). That is why personal data does not go on-chain: immutability makes rectification and erasure harder (Arts. 16 and 17). - **Transparency.**All transactions made will be immutably recorded on the blockchain. This ensures that any movement is verifiable and auditable, eliminating the need to rely on third parties to ensure data integrity. ## 04 / What is the process of developing a decentralized application? ### **Needs analysis** First, we sit down with you to understand exactly what you need. It's not just about applying blockchain because it's fashionable, but about really seeing how this technology can help your project. ### **Architecture design** This step is where we shape the technical structure. Designing a solution that not only works today, but that grows with you. How? Including everything necessary for the dApp to be scalable and adaptable, and if there are smart contracts involved, we ensure their correct integration. ### **Development of smart contracts** Smart contracts are our specialty, and in essence they are a fundamental part of dApps, since they execute automatically when certain conditions are met, eliminating the need for intermediaries and ensuring transparency. ### **Integration with blockchain** Now the step has come to connect your dApp to the blockchain network that best suits your business, taking into account key factors such as decentralization, security and scalability. ### **Safety and functionality tests** We don't take security lightly, so we carry out all the necessary tests to make sure everything works properly. ### **Launch and maintenance** Has the dApp launched? Perfect! But we didn't stop there. We also take care of maintenance, improvements and subsequent optimization. ## 05 / Why choose Unknown Gravity for dApp development? When it comes to developing a dApp, we don't just focus on being the best programmers, but on making sure that application fully adapts to what you need and that it meets any requirement that your project may require. **We like to strive to always give more**, studying your project well and looking for the best solutions, thus providing added value. ### Intuitive design and focused user experience One of the main qualities that any application must have is an intuitive and fluid design, since it should not only work, it must also be easy for users to use. We weren't going to be less, so we made sure that your dApp has a clear user interface, that every step is as intuitive as possible so that anyone can use it, and of course, we don't forget that it has an attractive visual experience, in order to make your users want to use it again. ### Efficient smart contracts It must be understood that when smart contracts exist within a dApp, it is the backbone of the dApp, this is because they ensure that the actions for which they are programmed are automated as soon as they are required. As we know the importance they have within your decentralized application, we focus on the fact that they are fully optimized for greater efficiency, avoiding processes that are unnecessary and may increase costs. In short, every line of code we build for your smart contract is meticulously designed to minimize flaws and unnecessary gas consumption. ### Cross-platform compatibility Why are you going to limit yourself to just one platform if you can be on all of them? We make sure that your dApp is compatible with any, mobile, web or any other device, we are not going to be the ones to set limits, that's clear to us. ### Scalability We build looking to the future. We ensure that your application evolves, adapts and responds with every step you take. Our development means that you can be ready for whatever comes, so that when your numbers multiply it will continue to work as it should. ### Security We didn't leave anything to chance and security was not going to be less. Before launching your dApp, we carry out a rigorous quality and security process, testing each smart contract integrated into the dApp, avoiding possible vulnerabilities and errors. Because, if one thing is clear to us, it is that both you and your users deserve to know exactly what was reviewed and what was not. No review leaves code free of flaws: it bounds the risk for a specific version. FAQ ## Frequently asked questions **What are the differences between dApps and traditional applications?** The main difference is that DApps interact with a blockchain network, leading to decentralization and achieving greater security, transparency and data protection. Traditional applications, on the other hand, do not interact with the blockchain and rely on centralized servers, making them more vulnerable to failures and hacks. **Can I integrate a dApp into my current system?** Yes. DApps are flexible, which means they can be integrated into your current system without having to disassemble everything you already have. It's not about starting from scratch, but about improving what already works. This page is informative. It is not legal, tax or investment advice, and it does not replace a case-by-case review.
