The primitive.

full primer →

Photographers keep the wallet they already have, but its classical key is wrapped in a post-quantum seed extension — the badge flips to 'quantum-safe' once the hash-based commitment unwraps for a royalty automation action.

Why this primitiveLoading details…

Kernel
a post-quantum seed extension that wraps an existing ECC/ECDSA wallet key, so the classical signature is only accepted after the hash-based commitment unwraps correctly
Drives the UI as
a two-layer key badge — classical address on top, post-quantum commitment underneath — with a 'quantum-safe' state
