Three taps,
your key is back.

A demo of one approach to passkey-gated key custody. Splits a private key across the devices you already carry, lets any quorum sign on demand. Supports both Sui and Solana, runs on Ika 2PC-MPC, gated by WebAuthn passkeys. The purpose is to show, not to ship.

One key.
Many keepers.

Setup takes about two minutes per device. Stop after the first if you want. Add more whenever you are ready.
