Web3 Application Development

Build usable wallet and payment experiences around clear application and trust boundaries.

Start with a business workflow

Build usable wallet and payment experiences around clear application and trust boundaries. We define the user, the information they need and the action they should be able to complete. The first release is scoped around a visible outcome that your team can review.

Relevant starting points

  • Wallet Membership Kit — Wallet sign-in and understandable access rules. Planned blueprint; software is not yet released.
  • Stablecoin Payment Operations — Connect payment events to usable business records. Planned blueprint; software is not yet released.

How the engagement works

  1. Scope: inspect the existing system and inputs, resolve risky assumptions and agree acceptance checks.
  2. Build: implement one end-to-end workflow, review it together and make the next scope decision.
  3. Deliver: verify the agreed behavior, document setup and release, and transfer the agreed source and operational access.

Designed for your next developer

The delivery scope can include a customer-controlled repository, module and API documentation, sample configuration without secrets, migrations, test fixtures and a recorded handover. Third-party components retain their own licenses; ownership and reuse rights for custom work are agreed in writing.

Working directly with Fone

I bring more than a decade in development and can take responsibility across the application stack. I lead the technical work directly. When design, QA or additional implementation capacity is useful, we agree collaborator roles and access as part of the project.

Estimate and support

Pricing and delivery dates follow a review of scope, integrations and dependencies. A public blueprint is a starting point for that discussion, not an off-the-shelf package or a fixed delivery promise. Ongoing maintenance, hosting and external-service costs are scoped separately.

Wallet and payment examples start in a test environment. Custody, token economics, financial advice and independent contract audits are outside these example scopes. Any custom contract work needs its own requirements and review plan.
