What does dApp development include?
- Product requirements and user flows
- Frontend implementation
- Wallet connection and indexed data
dApp development connects a product interface to blockchain actions and the data users need to understand them. It suits teams that have a clear use case but need a coherent application layer around their contracts, or teams that need the frontend and integrations developed together.
Start with a short list of user tasks, not a feature wish list. For each task, note what the user sees, what action they take, what on-chain result follows and what information must appear afterward. This exposes missing decisions early: for example, whether a screen needs a connected wallet, whether a user can review a transaction before submitting it, and how the interface reflects an updated record.
The scope can include a new interface, connection to existing contracts, indexing requirements, or a combination. Contract creation is a separate workstream when the application needs new on-chain logic; see smart contract development. If the product needs a broader technical plan, start with Web3 development.
Prepare a product description, available contract interfaces, preferred chain, design references and any existing frontend. If some inputs are not ready, identify them as open decisions instead of treating them as settled requirements. AEOTech records these assumptions in the Launch Spec so both sides can review the same scope before work starts.
How should the dApp frontend handle wallet connection?
- Show the connection state clearly
- Separate review, submission and confirmation states
- Provide useful recovery paths
A dApp frontend should make each wallet-dependent action understandable before the user signs. The interface needs defined behavior for a disconnected wallet, a connected account, a rejected request and a transaction that has been submitted but is not yet reflected in the application. These are product states to design and test, not incidental details to leave until the final pass.
During the Spec Review, we check the screens against the expected user journey. For each wallet interaction, agree what information is shown before confirmation, what the user can do if they cancel, and how the interface responds if the selected account or network changes. Keep transaction feedback specific: distinguish an action waiting on the wallet from an action whose result has been received by the application.
A useful handoff includes the supported connection flow, required account and network behavior, user-facing error copy and the expected response after a transaction. If the product also needs a public marketing site, it can be scoped separately through Web3 website and landing development. When a Telegram interface is the primary product surface, compare that requirement with Telegram bot and mini app development.
Before implementation, provide any existing design system, wallet requirements and contract interaction details. If these are still being decided, we can document the alternatives and their effect on the frontend scope rather than silently choosing for you.
What should a dApp indexing plan cover?
- Data required by each screen
- How the application reads and presents it
- Freshness expectations and empty states
Indexing is the plan for making relevant blockchain activity usable in application views. It matters when a product needs to present records, activity or other chain-related information in a form that supports its user tasks. The right scope starts from the interface: list the screens and the fields each screen needs, then connect those needs to the available data sources and contract events.
Write down which information must appear immediately after a user action and which can appear after the application refreshes its data. Define how the interface behaves when a user has no records, when a result is unavailable, or when the displayed information has not caught up with the latest action. This gives implementation and testing a concrete target without making assumptions about undocumented platform behavior.
Indexing work should also identify ownership and operational expectations. Agree who provides access to existing infrastructure, who reviews data mappings and how changes to contract behavior will be communicated. If the product depends on contract changes, coordinate the application scope with token creation and deployment or the relevant smart contract development work.
The Channel Matrix records the application surfaces and their data needs in one view. Use it to check that each planned screen has a source, a display rule and an agreed behavior for missing or delayed data. This is especially useful when frontend, contract and indexing work are handled by different contributors.
What do you receive from a dApp development project?
- A reviewed scope and implementation plan
- Agreed frontend and integration work
- A handoff describing what was delivered
The deliverables follow the approved scope, rather than an assumed one-size-fits-all package. For a dApp centered on an existing product, that may mean building the frontend and integrating wallet connection. A product with data-heavy views may also need an indexing workstream. The exact combination is confirmed before implementation so the work can be reviewed against specific requirements.
| Work area | Scope decisions to document |
|---|---|
| Frontend | Screens, user tasks and responsive behavior |
| Wallet connection | Connection states and transaction feedback |
| Indexing | Required fields, display rules and refresh expectations |
| Handoff | Delivered work, known assumptions and next actions |
The project handoff should make it clear what was built, what inputs were used and which decisions remain with your team. Share your existing repository and design assets early if they are part of the project. Also identify who can answer product questions and approve the interface; delayed access or unresolved decisions can hold up work that depends on them.
If the application includes a separate digital collectible experience, align the requirements with NFT collection development. If you need help comparing delivery options, the pricing page gives the broader service context. The estimate for this service is from $5,390 / project; final scope is set after reviewing requirements and dependencies.
How does a dApp project move from brief to handoff?
- Confirm inputs and scope
- Build against reviewed requirements
- Record work and close with a Readout
A dApp project moves through a defined review and delivery sequence. The first task is to establish what exists already: product requirements, design materials, contracts, access and a decision-maker for approvals. AEOTech then identifies dependencies and records the proposed frontend, wallet and indexing scope for review.
The Launch Spec is the shared reference for the agreed features, assumptions and inputs. Once it is reviewed, implementation follows the approved work areas. We raise questions when a missing input affects a user flow or integration instead of quietly expanding or redefining the scope. Your team reviews the relevant interface and behavior as work progresses, so corrections can be tied to the requirement they address.
A Run Log records delivery progress, open questions and decisions that affect the project. At handoff, the Readout summarizes completed work and any agreed follow-up items. Timing is planned around the scope, access to required materials, integration dependencies and review turnaround; we confirm the schedule after understanding those factors.
To begin, send a short product description, preferred chain, available contract details, design or repository links, and the user journeys you want to support. We will review those inputs, identify the decisions that need your approval and return a project scope for discussion.
Which dApp delivery limits should the team plan for?
- Confirm platform and contract behavior from available documentation
- Test the application against agreed user flows
- Separate delivered work from third-party outcomes
A dApp team can implement and verify the agreed interface, wallet flow and data handling within the project scope. We cannot control whether a wallet provider changes its interface or permissions, whether a network or external data source is available, or when indexed information becomes visible. Those behaviors can affect what a user sees even when the application code has been delivered as specified.
Before approval, identify the external dependencies the product relies on and decide how the interface should respond when one is unavailable. Confirm who owns each dependency, which test environment is available and what evidence your team expects for review. These decisions let the project define observable acceptance criteria without promising behavior controlled by a wallet, network or indexing service.
When you contact AEOTech, include the product description, preferred chain, available contracts and a sample of the screens or user journeys you want to build. We will use them to prepare a scoped review of the frontend, wallet connection and indexing work, then confirm the next project decisions with you.

Frequently asked questions
What do you need from me to scope a dApp?
Send a product description, the user tasks the application must support, your preferred chain, and any available contracts, designs or repository. Tell us who can approve product decisions. If a requirement is not settled, label it as open; that helps us distinguish confirmed scope from decisions that may affect implementation.
Can you connect a frontend to contracts we already have?
Yes. Share the available contract details and describe the user actions the frontend needs to support. We can scope the interface and integration around those inputs. If the contract behavior or documentation leaves an important user flow unclear, we will identify that question for review before treating the flow as ready to implement.
Why does a dApp need indexing?
Indexing helps organize blockchain-related information for the application views that need to present it. Whether it belongs in your project depends on the screens and data users need. A product with no requirement for indexed views may not need this workstream; list the required fields and user tasks first, then scope the appropriate approach.
How much does dApp development cost?
Projects start from $5,390 / project. The scope is reviewed before work begins, because the frontend, wallet connection, indexing requirements, existing materials and integrations determine what needs to be delivered. Send the requirements and available technical inputs for a project-specific scope.
How long does a dApp project take?
We confirm timing after reviewing the features, dependencies, access and approval process. A focused frontend scope and a project that also requires contract coordination or indexing have different work to plan. Provide the available materials and identify who will review decisions so the schedule can reflect the actual project.
Can you guarantee that a wallet or indexer will always show the expected result?
No. We can deliver and test the agreed application behavior using the available requirements and environment, but wallet providers control their own interfaces and permissions, while networks and external data services control availability and data timing. We define visible states for those cases so the dApp communicates what it can observe.
What should happen when a user rejects a wallet request?
The interface should keep the user informed and offer a clear next action without implying that the request succeeded. During scope review, define the message and recovery path for a rejected request, a disconnected wallet and a transaction that has not yet appeared in the application. These behaviors should be included in the relevant user-flow review.
