THE CONTROL MODEL

Capital can move. The rules stay in place.

Three Coffer treasury controls: policy enforcement, autonomous execution, and human oversight

01 / MANDATES

Give agents a mandate — not a wallet.

Set enforceable spending caps, approved counterparties, bucket boundaries, expiry, and revocation. The agent can operate, but it cannot rewrite the rules.

Encrypted invoice layers separated from public financial execution

02 / COMMERCIAL PRIVACY

Private commercial context. Verifiable financial execution.

Seal encrypts invoice content before Walrus stores the ciphertext. Access is policy-controlled; execution remains independently auditable.

Amounts and recipient addresses remain public on Sui.

03 / HUMAN CONTROL

Humans approve exceptions. Not every transaction.

Routine payments execute inside the mandate. Material exceptions request a fresh authorization bound to one action and one expiry window.

Event authorization uses mocked identities.

04 / EVIDENCE

Every decision leaves a receipt.

Agent evaluation, deterministic policy checks, authorization, and settlement produce an inspectable operational history.
