Prism: Digital Assets for Nucleus BankOS
Digital assets, born on the core.
Most banks bolt crypto onto the side. Prism builds it into the core — a regulated digital-asset operating system on the same ledger, identity, and controls that run the rest of the bank.
One ledger. On-chain and off.

The gap is where risk hides
For a decade, the ledger lived in one world and the chain in another.
A stablecoin balance isn’t a number in a third-party portal. On Prism it’s a first-class account on your books — reconciled to the chain every cycle, backed by attested reserves, governed by the same controls as every other dollar you hold.
The old way · bolted on
- Crypto vendor stapled to the edge of the bank
- Two ledgers, reconciled by spreadsheet
- Audited by hope
- The gap between systems is where risk hides
With Prism · born on the core
- One ledger, on-chain and off
- The same customer identity and compliance fabric
- Reconciled to the chain every cycle, automatically
- Attested reserves and a single audit trail
That changes what digital assets are for a bank. Not a side bet. Core infrastructure.
What it does
A digital-asset desk, run like the rest of the bank.
Custody
Custody you can defend in an exam.
Hot, warm, and cold tiers across MPC, HSM, and multi-signature wallets — with quorum thresholds, scheduled key rotation, and dual control on every sensitive operation. Every key ceremony and policy change writes an immutable evidence packet automatically.

Compliance
Compliance that runs before the transaction, not after.
Sanctions and wallet-risk screening, Travel Rule orchestration, and on-chain analytics are wired into the transaction lifecycle itself. Screening, signing, broadcast, and settlement move as one governed flow — and anything anomalous escalates straight into the fusion center alongside BSA, fraud, and cyber.

One governed flow
Reconciliation
Reconciliation that closes itself.
On-chain balances reconcile against the ledger continuously. Known break patterns resolve automatically; the exceptions that need a human get routed as work, not buried in a report. Proof-of-reserves attestations are a click, not a fire drill.
- Continuous on-chain ↔ ledger reconciliation
- Known breaks resolve automatically
- Exceptions routed as work
- Proof-of-reserves in one click

AI workforce
An AI workforce on the desk.
CLARA agents watch the operation around the clock — surfacing what matters and handling what’s routine, so a small team can run a serious book.
- Sentinel — transaction anomalies
- Custodian — wallet & key health
- Reconciler — break analysis
- Around-the-clock, governed coverage
Sentinel
Transaction anomaliesWatches every transfer and escalates the rest.
Custodian
Wallet & key healthMonitors balances, rotation, and quorum health.
Reconciler
Break analysisClears known breaks, routes true exceptions.
The proof point
The difference between a bank that offers crypto and one that can run it.
Because Prism sits on the core instead of beside it, there’s one source of truth for every digital-asset dollar.
One ledger
Every digital-asset dollar is a first-class entry in the same double-entry GL as the rest of the bank.
One customer record
The same identity and KYC/KYB that govern every other account govern the wallet behind it.
One set of controls
RBAC, dual control, and approval chains apply on-chain exactly as they do off-chain.
One audit trail
Key ceremonies, screenings, and reconciliations all land in the same immutable record.
The stablecoin rail your examiner can read.
