Web and mobile app development for Web3 products

What will your Web3 app or website include?

A Web3 application project gives you a defined set of screens and functions that people can use, rather than a design file alone. The visible result may be a landing page, a corporate website, a web application or a mobile application; the exact combination is agreed before development starts.

At CoinMarketingCap, we begin by turning your product brief into a scope that connects each user need to a screen, action or piece of content. That makes it easier to decide what belongs in the first release and what can wait. Depending on the project, deliverables can include:

• Interface design and adaptation for desktop, mobile and tablet.
• Business logic and workflows for the features in scope.
• Website functionality, page creation or an admin panel.
• SEO setup, AI integration or maintenance where required.

For a focused campaign page, compare the scope with our landing page design service. For a broader visual system, see brand book development. We can also map a combined design and development brief through the studio.

How do design and screen adaptation work?

Design and adaptation make the same product experience usable across the screen sizes included in your scope. The project starts with the people using the product, the information they need, and the actions they must be able to complete.

We use those requirements to shape the page structure and interface before building the features. For mobile and tablet layouts, we review how content, navigation and controls fit the available screen, rather than simply shrinking a desktop composition. You can help the review move quickly by preparing:

• A short description of the product and its intended users.
• Existing brand assets, content and any interface examples you want us to consider.
• The main user tasks, such as finding information, submitting details or using a feature.
• Any screen sizes or devices that are especially important to your audience.

If the project also needs a distinct campaign page, the landing page design service can clarify the design scope. Feedback is most useful when it identifies a specific screen, user task or content issue; that gives the team a clear next revision to make.

How are app features and business logic scoped?

Features are developed from agreed user actions and business rules, so the interface and the underlying workflow describe the same product. Before implementation, we clarify what a user can do, what information the product needs, and how each step should respond.

A useful feature brief describes the starting point, the user’s action and the expected outcome. For example, specify what information a form collects, what the user sees after submitting it, and who needs access to the submitted information. For a more involved application, separate essential workflows from optional enhancements. This lets you review the first scope as a coherent product, rather than an unprioritized feature list.

For each feature in scope, agree on its visible behavior and what counts as complete. If a workflow relies on content, access or decisions supplied by your team, identify the owner and provide that material during the project. AI integration can also be considered as a feature, with its role and user-facing behavior written into the requirements. We confirm the agreed scope before build work begins, then use that scope to guide review and handover.

Can the build include SEO setup and AI integration?

Yes. Website development can include SEO setup, and an application can include AI integration when those needs are part of the agreed requirements. These are scoped as practical project tasks, not as a promise about future search placement or product performance.

For SEO setup, identify the pages that need to explain the product, the audience for each page and the content you can provide. We can include the agreed setup alongside page structure and website functionality. If you need an admin panel or page creation, specify who will maintain the content after handover and what they need to change themselves.

For AI integration, describe the user problem it should address and where the interaction belongs in the product. Also note any access, content or decisions your team must provide. That makes it possible to discuss a useful feature before committing it to scope. Where search visibility is a separate priority, consider our AI search visibility services as a related area of work. A clear distinction between a product feature and a marketing objective helps keep the build brief focused.

How do we verify the build before handover?

We verify a build against the agreed screens, functions and workflows, then give you a clear record of what was reviewed. The Evidence Pack brings together the project scope and delivery materials, so your team can check the work against the requirements rather than relying on a vague “finished” status.

The working sequence is straightforward:

• Confirm the purpose, users, priority features and required screens.
• Agree the design and implementation scope, including any SEO or AI work.
• Build the defined experience and review it against the requirements.
• Resolve in-scope feedback, then prepare the handover and support discussion.

A Visibility Check is useful during review: we look at the delivered pages and functions from the user’s point of view and flag items that need attention within the agreed scope. To make review efficient, provide one consolidated set of feedback and identify the relevant screen or workflow for each note. The project brief and feedback format can be aligned with our how we work guidance. Scope and term are agreed per project, so the sequence is tailored to the work rather than forced into a fixed schedule.

What should you plan for after launch?

After handover, your team should know how to manage the website or application and where further work would be requested. Website projects can include maintenance and management assistance; the scope should state what support you need and which parts of the product it covers.

Prepare for that conversation by identifying who will update content, who will handle product decisions and whether you expect new features after the initial build. If you need internal control of website content, include an admin panel or page creation in the brief. If you expect ongoing development, describe the kinds of changes you anticipate so the support discussion is grounded in actual needs.

Third-party hosting availability, browser changes and external service behavior can affect how a delivered application works after handover; we cannot control those systems. We can agree and verify the development work in scope, but not promise uninterrupted operation of services outside the project. For a broader creative requirement, review the design, video and development studio. Send us your product goal, required features, existing assets and preferred launch sequence; CoinMarketingCap will review them and return a project scope for discussion.

How it works

1. Share the product briefDescribe the audience, the main user task and the product problem the site or app should solve. Include existing content, brand assets and any current product materials.
2. Set prioritiesSeparate essential screens and workflows from ideas that can follow later. Note who on your team can answer product and content questions.
3. Agree the scopeConfirm design, functionality, screen adaptation, SEO setup, AI integration and maintenance needs. The agreed scope also defines what will be reviewed at handover.
4. Build and reviewThe team develops the agreed experience and checks it against the requirements. You provide consolidated feedback tied to the relevant screen or workflow.
5. Handover and supportReview the completed work and delivery materials, then confirm any maintenance or follow-on development needs with the team.
