Operating principles04 rows

  1. Correctness

    Double‑entry discipline applied to code: every state change should balance, and every rule should be testable.

  2. Audit trails

    Systems should explain themselves — events, logs, and records that survive scrutiny long after the transaction.

  3. Threat modeling

    Assume adversarial inputs. Identify who can call what, with which funds, before the logic is written.

  4. Composability

    Small, well‑defined modules that integrate cleanly with the platforms finance teams already run.
