Which wallet model fits your product?
The right wallet model is the one your users can operate and your team can support. Start by deciding who controls keys, which actions the wallet enables and what support responsibilities your product will take on.
A custodial wallet places key management within the product’s operating model. It can suit services that need a managed user journey, but requires a clear plan for account access, operational controls and counsel review of regulatory classification before launch. A non-custodial wallet gives users control of their keys; the interface must make signing, recovery expectations and transaction details understandable.
Use the kickoff to answer these questions:
- Who creates and controls the wallet, and what happens when a user loses access?
- Which user actions are essential at launch: receive, send, swap or connect to an application?
- Which chains and assets are required for the first release, and which can wait?
- What support and operational tasks will your team own after release?
We capture those decisions in the product scope before implementation begins. If the wallet is part of a broader application, align its journeys with dApp development and any required smart contract development. This prevents the wallet experience from being designed separately from the product actions it needs to support.
How should wallet features work across browser, mobile and Telegram?
A wallet’s delivery channel shapes how users enter, review and complete each transaction. We map the user journey for the chosen channel first, then define the screens and integrations that make each action clear.
A browser extension can place wallet access close to a web product. A mobile app supports a dedicated mobile journey. A Telegram Mini App can bring wallet-related actions into a Telegram experience. These are different product surfaces, not interchangeable wrappers: navigation, account access, transaction confirmation and support entry points need to be designed for the selected channel.
For each key flow, agree on:
- The starting point: connect, create an account or open an existing wallet.
- The information shown before a user confirms a send or swap.
- The feedback shown after submission, including a clear pending or completed state.
- The route to help when an action fails or the user is unsure what to do.
Then confirm the chain support and external integrations each flow requires. We document the decisions in a Channel Board so the interface, implementation and testing share one reference. For a Telegram-first product, coordinate the wallet journey with Telegram bot and Mini App development. If the product also needs a dedicated phone experience, scope it alongside Web3 mobile app development.
What should the wallet security review cover?
A useful wallet security review starts with the actual design: key management, permissions, transaction paths, connected services and operational responsibilities. It should produce findings your team can act on before release, not just a checklist detached from the product.
During the Launch Sprint, we review the agreed wallet architecture and trace important user actions from interface to integration. The work can include checking how the chosen custody approach is represented in the product, reviewing transaction and swap flows, identifying external dependencies and preparing materials for an independent security assessment. We also plan backend and monitoring needs that fit the wallet’s scope.
Prepare these items for review:
- A diagram or written description of the wallet architecture and key-management approach.
- The intended chains, assets, transaction flows and swap integrations.
- A list of external services and the data each one handles.
- Existing design files, implementation notes and known operational constraints.
We record open questions, decisions and follow-up actions so your team can resolve them in sequence. Where the wallet depends on on-chain logic, coordinate the review with smart contract development. For a user-facing product that needs a connected web experience, align the implementation with Web3 website and landing development.
How does a wallet project move from kickoff to release?
A wallet project moves forward through defined decisions, implementation, testing and launch preparation. In the Kickoff Week, we confirm users, custody choices, channel, chain scope, essential features and the information needed from your team.
After kickoff, we turn the agreed scope into a build sequence. The team implements the selected wallet experience and integrations, then checks the primary journeys against the agreed requirements. Your team reviews work at planned checkpoints, so product decisions and feedback reach the people building the wallet while changes are still actionable.
Before release, we confirm what is ready, what remains open and who owns each follow-up. Security review preparation and audit coordination are included in the plan where they fit the agreed scope. The handoff can cover product behavior, integration notes, operational considerations and the status of outstanding items.
You receive a Pulse Report with progress, completed work, decisions needed and next actions. This gives founders and product leads a concise way to review delivery without treating a feature list as proof of readiness. For a broader product roadmap, connect the wallet scope to Web3 development and identify dependencies before committing to release work.
What can change during a wallet launch?
Wallet launch readiness depends on the product decisions and third-party components the team can verify and control. The practical way to reduce surprises is to make those dependencies visible early and assign an owner to each open item.
During planning, list the chain integrations, external services, review inputs and operational tasks needed for the intended release. Mark which items your team controls, which need a provider’s cooperation and which require counsel or an independent reviewer. Keep launch scope focused on the user journeys that matter most, and record deferred features explicitly rather than leaving them implicit.
A short limits note: third-party chain and integration behavior can change outside the development team’s control, and an independent reviewer may identify issues that require further work. We can deliver the agreed implementation and review preparation, but cannot promise a third party’s availability, a reviewer’s conclusion or acceptance of a custodial product’s regulatory classification.
Before approving a release, check that the team has reviewed the key user journeys, documented unresolved issues and assigned post-launch monitoring ownership. This makes the decision concrete: the team knows what is ready, what remains open and who must act next.
How can wallet development connect to the rest of your product?
Wallet development is most effective when it fits the product around it. Decide which parts must ship together, and identify adjacent work early so the wallet is not waiting on an unplanned interface, contract or user-support dependency.
A wallet connected to an application may need coordinated dApp development. A Telegram-first experience can pair with Telegram bot and Mini App development, while a separate phone interface may need mobile app development. If the project needs a shared web entry point, align it with Web3 website development. Each link represents a separate scope to discuss; it does not automatically add that work to the wallet project.
To make the first discussion useful, send a short brief with:
- Your product goal and intended users.
- Custodial or non-custodial preference, if decided.
- Target channel, chains and essential transaction flows.
- Known integrations, security review plans and launch constraints.
BrandBoost Guru reviews that material in the Kickoff Week and returns a scoped plan with decisions, dependencies and next actions. Send your wallet brief through contact, and we’ll use it to shape the first project conversation.

Frequently asked questions
What do you need from us to start crypto wallet development?
Start with your product goal, intended users, preferred custody model, delivery channel and the main actions users need to perform. Share target chains, integrations, existing design or technical material, and any known security review requirements. If some decisions are still open, we use kickoff to identify them and document what the team needs to resolve before implementation.
How do we choose between a custodial and non-custodial wallet?
Choose based on key control, user expectations and your team’s operational responsibilities. A custodial model places key management within the product’s operating model; a non-custodial model gives users control of their keys. We help map the implications for the interface and technical scope. Have counsel review the regulatory classification of a custodial product before launch.
Can you develop a browser extension and a Telegram Mini App wallet?
Yes. We can scope a browser extension, Telegram Mini App or another supported delivery channel as part of the wallet project. The right scope depends on the user journey you want to support. We define account access, transaction confirmation, feedback and support paths for each selected surface rather than assuming one interface will fit every channel.
How long does a crypto wallet project take?
Timing follows the agreed scope. A wallet with a focused channel and a small set of essential flows has fewer decisions and dependencies than a product combining multiple channels, chains, swaps and external integrations. During the Kickoff Week, we map those requirements and set a delivery sequence with review points, implementation work and launch preparation.
Does the wallet project include an independent security audit?
We can prepare the architecture, implementation notes and review materials needed for an independent security assessment, and include audit coordination when it is part of the agreed scope. An independent reviewer performs their own assessment and reports their conclusions. Share any existing audit plans or requirements during kickoff so we can reflect them in the project plan.
What is the starting price for crypto wallet development?
Crypto wallet development starts from $6,600 / project. The scoped proposal reflects the selected custody model, delivery channel, chains, transaction and swap flows, integrations, security review preparation and backend needs. Send us your product brief so we can identify the work required and confirm a project scope before development begins.
