Wallets where the custody model is chosen deliberately — and key management, recovery and signing are designed as the product, not around it.
Four areas where this work is won or lost.
The user holds the key and your product can never move their funds, with recovery designed so loss is not fatal.
Where you hold keys, the regulatory position, key storage and operational controls that come with that.
Account abstraction and MPC so onboarding feels like a normal app while the user keeps control.
Shared control for teams and treasuries, with signers on separate devices and a written recovery path.
A short loop with a written result at every step.
The single decision that sets your regulatory position, security burden and support load, reviewed with legal.
Generation, storage, signing and recovery specified before any interface is drawn.
Multi-chain support, transaction simulation and a security review before public release.
Chosen for your product, not for our habit.
Tell us the users and the jurisdictions. We will lay out what each custody model costs you.
