AWARDS & RECOGNITION
FREQUENTLY ASKED QUESTIONS
Answers to the most common questions about our crypto web design and development process, cooperation models, and what it’s like to work with Overcode.
What are Web3 product development services?
Web3 product development services include the creation of decentralized applications (dApps) and solutions based on blockchain technologies. We focus on designing and building web & mobile apps, and integrating them with smart contracts and web3 wallets.
The goal of development is to create secure, transparent, and user-oriented products that operate without intermediaries. Such technologies give users control over their data and digital assets.
How much does blockchain development cost, and what factors influence the price?
Each project is unique, and the exact cost depends on the following factors:
- Blockchain type;
- The scope of work and complexity of the project features;
- Selected technology stack and security requirements;
- Interface design;
- Integrations with external services.
How long will it take to develop and deploy the blockchain solution?
The total time depends on the scale and complexity of the project, as well as the availability of the team and the customer's involvement at each stage. One stage usually takes from one to several months of work. The main stages include:
- Requirements Analysis and Planning;
- UX/UI Design and Prototyping;
- Software Development: front-end development, API development, integration with smart-contracts and 3rd-party services;
- Release and User Testing;
- Ongoing support and Updates.
How can I assess the progress of my blockchain project?
During the cooperation, we will hold regular meetings where we will present updates on the work process. At the research and design stage, we will show the process in special programs where we organize project documentation and create interface design. And after the start of development, we will prepare a separate staging server for you, where we will add functionality ready for testing by the client. With this approach, you will be aware of all changes as the work progresses. We will also systematize the client’s feedback regularly to implement in the next iterations.
Can you integrate Web3 features into an existing Web2 product?
Yes. Integrating Web3 features into a Web2 product will give you new opportunities and attract users interested in decentralized technologies and cryptocurrencies. We can integrate your existing product with smart contracts, upgrade your website to accept cryptocurrency payments, implement decentralized authentication, data storage, NFTs, and more.
Do you offer custom blockchain development services? How can Overcode help you with Web 3.0 development?
Yes, we provide custom blockchain solution development services. A custom solution is developed from scratch or adapted to meet the specific needs of a company. This includes creating an individual architecture, unique smart contracts, tokens, consensus algorithms, and other components that precisely match business goals. With a custom solution, you gain full control over the system's functionality, security, scalability, and other key aspects. Also, a custom solution can be optimized for specific tasks, which provides high performance and scalability.
We can help you implement advanced Web 3.0 technologies to improve security, transparency, and control over digital assets. Overcode can provide services such as:
- UX/UI design;
- Full-stack development: front-end and API creation;
- Smart Contracts integration.
Do you provide project support & maintenance services?/What kind of post-deployment support do you provide?
We see great value in long-term cooperation. That's why our clients refer us repeatedly and recommend us to their professional network.
After the release, we will stay with you. We make sure everything is stable, fix bugs quickly, and add new features as your product grows. We offer different formats of support, such as one-time enhancements or ongoing support on a subscription basis. You can stop worrying about maintaining our work, because we are always on call and ready to help.
How soon can Overcode start with the development of my project?
We get into the project from the first contact with the client. And then we work together to develop a plan for further action. Usually, the plan contains analysis, time and budget estimates from our side, contract signing, and preparatory works. Depending on the complexity of the project and our internal workload, the process can take from two to four weeks after the initial meeting.
Can the solution handle large volumes of data?
Yes, our solutions can be adapted to handle large volumes of data. We design systems that not only scale well but also efficiently handle the growing flow of information and requests. We use advanced blockchain platforms and distributed storage such as IPFS, so we guarantee fast and secure data processing, even under high loads! Your data will always be under control, and the system will work without slowdowns, regardless of its volume.
Do you accept payments in crypto?
We can discuss this — you can pay for our services in a way that is convenient and secure for you. If you have a preference for a specific cryptocurrency, we are always ready to talk about the options.
