UNYKORN STUDIO // THE EXECUTION SUBSTRATE

Every Contract Produces a Hash-Chained Audit Trail

Smart contracts in traditional finance cannot be a black box. The Unykorn Studio executor drives these contracts through an approval-per-step model: every state change requires human or multi-sig quorum signoff, recorded permanently in an immutable SHA-256 hash-chained receipt ledger.
