What it does
A digital-asset desk, run like the rest of the bank.
Custody you can defend in an exam
Hot, warm and cold tiers across MPC, HSM and multi-signature wallets, with quorum thresholds and dual control. Every key ceremony writes an evidence packet automatically.
Compliance before the transaction
Screening, signing, broadcast and settlement move as one governed flow. Anomalies escalate into DarkMatter alongside BSA, fraud and cyber.
- Sanctions and wallet-risk screening
- Travel Rule orchestration
- On-chain analytics, inline
Reconciliation that closes itself
On-chain balances reconcile to the ledger continuously, and known break patterns resolve automatically. True exceptions route to a person as work.

Questions
Prism: what banks ask
What is Prism?
Prism is the Nucleus BankOS module for regulated digital assets. Stablecoin and tokenized-asset balances are accounts on the bank’s own double-entry ledger, governed by the same identity, KYC and controls as every other account.
How does Prism hold keys?
Across hot, warm and cold tiers using MPC, HSM and multi-signature wallets, with quorum thresholds, scheduled rotation and dual control. Each key ceremony and policy change writes an immutable evidence packet.
Where does compliance screening happen?
Inside the transaction flow, before signing. Sanctions and wallet-risk screening, Travel Rule orchestration and on-chain analytics run inline, and anomalies escalate into DarkMatter.
How are on-chain balances reconciled?
Continuously against the ledger. Known break patterns resolve automatically, true exceptions route to a person, and proof-of-reserves attestations are generated on demand.
Does Prism require Nucleus BankOS?
Yes. Prism is a module that runs on the Nucleus BankOS ledger.
