Wallet Membership Kit — product blueprint

2026-09-29 Product blueprints Products & Resources
Membership card and Ethereum wallet card illustrating wallet-based account eligibility.
Connect verified wallet identity with clearly defined membership eligibility.

Planned product · Custom development enquiries open

This is a proposed product scope. There is no released software, working demo or source-code download yet. You can download the planning brief below or discuss a custom implementation.

Who this is for

Web3 product teams adding account access, community tools or membership experiences.

The problem worth solving

Connecting a wallet is often mistaken for logging in. Users get stuck when they cancel signing, change accounts or return to an expired session.

A useful first workflow

A member connects a supported wallet, signs a clear login challenge and enters the application. The server checks the access rule and shows a useful explanation when membership cannot be confirmed.

Proposed first release

  • One EVM network and an agreed supported-wallet list
  • Server-verified message signing and application sessions
  • One membership rule with a read-only chain adapter
  • Account-change, signature-cancellation and recovery interfaces

Designed for further development

  • Separate wallet identity from application roles and business permissions
  • Swap the membership resolver without replacing the UI
  • Add a second network only after its verification and indexing behavior is scoped

The implementation plan calls for a customer-controlled repository, documented module boundaries, migrations, sample data and setup instructions. Deliverables, third-party licenses and any redistribution rights are agreed in the project scope. No existing reusable implementation is claimed on this page.

Acceptance checks to agree

  • Expired or replayed challenges are rejected
  • An account change does not reveal the previous account’s data
  • A failed chain lookup shows an unknown state rather than granting access
  • An operator can explain why access was granted or denied

Scope boundaries

Token launches, custody, investment features and audited smart-contract claims are not included. Contract changes and independent review are separately scoped.

What to bring to a discussion

Specify the chain, wallets, membership rule and what users should be able to do after signing in.

Build it for your workflow

I lead the technical work directly and involve collaborators when the agreed scope needs them. We begin with the data, integration constraints and acceptance checks, then agree the release and handover.
