The challenge
A regional bank wanted to issue and settle tokenized assets without handing control to a public chain or a black-box vendor. They needed custody they could audit, a settlement path their regulators understood, and a way to prove every movement after the fact.
The brief was deliberately small: one asset class, one permissioned ledger, in production — not a year-long platform that never ships.
What we built
We stood up a permissioned ledger with role-based issuance, hardware-backed custody, and a compliance dashboard that renders the full audit trail in plain language. The smart contracts were gas-aware and audited before they touched a real balance.
Settlement runs on a 24/7 window with deterministic finality, and every action — issuance, transfer, redemption — lands in an immutable, queryable record the bank's own auditors can read without us in the room.
The ledger should be an implementation detail your auditors trust, not a strategic bet the business has to defend.Protocore · Engineering principles
The outcome
The pilot reached production in four weeks and onboarded three asset classes within the quarter, with full audit-trail coverage. The bank kept custody, kept its regulators close, and shipped a rail it can extend on its own terms.
