The thesis

Most financial products are stitched from a dozen vendors and three reconciliations. AUREUS settles banking, payments, and digital assets to one immutable ledger — so every dollar, every satoshi, and every basis point ties out, in real time.

The ledger

Every movement, balanced.

A transaction lands; debits and credits post atomically; references settle in. Nothing moves money except a balanced entry — append-only, auditable to the entry.

  • Double-entry, append-only, immutable
  • Debits equal credits, enforced in SQL
  • Balances derived, never stored
  • Every entry auditable to the cent

Developer experience

Primitives, not platforms.

Clean, typed, idempotent. Every money-moving call takes an Idempotency-Key, and every response ties back to a ledger entry you can audit.

  • Typed SDKs — Node, Python, Go
  • Idempotent by default
  • Signed, replayable webhooks
  • OpenAPI 3.1 · generated clients

Built to be trusted

Trust, engineered in.

The controls an institution audits before it moves a dollar — and the uptime a builder ships on without thinking about it.

Immutable ledger & audit

Append-only and double-entry. Balances are derived from entries, never stored — every figure auditable to the cent and the timestamp.

Compliance, built in

KYC, KYB, AML, and real-time sanctions screening at onboarding and on every movement. Controls your regulators and ours both recognize.

Controls & uptime

Role-based approvals, signed webhooks, and least-privilege access on infrastructure engineered for continuous settlement.

  • SOC 2 Type II
  • PCI DSS
  • ISO 27001

We replaced four vendors and a reconciliation team with one ledger. Our auditors stopped asking how the numbers tie out — they just do.
