Independent browser wallet development with origin-aware permissions, account connections and transaction confirmation interfaces.
A MetaMask-like browser wallet must maintain a strong boundary between websites and signing authority. We develop an original extension experience that identifies requesting origins, scopes supported methods and explains account permissions. Browser lifecycle and extension update behaviour are included in the design.
Validate every request crossing the extension interface.
Define when renewed authentication is required.
Offer a scoped connection and signing experience.
Restrict supported networks and application origins.
Provide documented methods for participating applications.
Track which sites can request supported account access.
Present transaction and message context before approval.
Handle locking, background restarts and session recovery.
Let users inspect and revoke application permissions.
Specify extension and custody boundaries.
Design origin-aware permission flows.
Build request validation and confirmations.
Test hostile requests and background restarts.
Prepare reviewed distribution and update procedures.
We choose the implementation tools after confirming the architecture and integrations.
No. The proposed scope is independent development with original branding and reviewed dependencies.
No. Website requests must remain separated from protected signing material.
Independent custom development; not affiliated with MetaMask. No proprietary vendor code or branding is included.
