The problem

Mainstream users should be able to hold and send crypto without ever seeing a seed phrase — and the app has to pass App Store review for a crypto wallet, which rejects most first attempts.

How we build it

MPC key shares split between the device and Blocsafe signers, Face ID or fingerprint as the signing gate, and a policy layer that adds friction only for large or unusual transfers. Store compliance is handled as part of the build, not after it.

BUILT TO

Seed phrases shown to users — ever

<60s

Onboarding — a balance before a single word of jargon

Policy

Not paranoia — friction only for large or unusual transfers

Recovery

People can actually do — email plus biometrics, no paper backups

Onboarding in under a minute

Sign up with email or passkey; the wallet is created silently in the background with MPC. Users see a balance before they see a single word of crypto jargon.

Policy, not paranoia

Small transfers sign instantly; anything above a threshold or to a new address asks for biometrics and a short delay. The rules run on Blocsafe’s policy engine, so they can be tuned without an app release.

Recovery people can actually do

Lost phone? A new device re-shares the key with email plus biometric verification and a 24-hour cool-down. No paper backups, no support tickets with private keys in them.
