Agentic Interface · v2 architecture
6 agents · 1 chain · sub-cent settlement viable

The orchestration layer for agent-mediated settlement.

Six specialized agents — coordinating compliance, risk scoring, atomic execution, and programmable reversibility — that move institutional capital across Solstice in seconds, with auditability from the first byte.

Prologue · The supervisor problem

Agent-initiated transactions will dwarf human ones. Phone calls and T+2 batch jobs can't supervise machines.

compliance post-hoc · overnight batch risk · clawback by litigation — the legacy posture

Chapter 01 · The relay

Six agents. No shortcuts.

01 · Intent

An operator mandate — or an autonomous treasury policy — lands with Maestro, the orchestrator. It classifies the intent and owns the pipeline.

02 · Compliance

Concord runs six deterministic checks before anything moves — jurisdiction, status, balance, purpose, sanctions, eligibility. Before, not after.

03 · Risk

Fermata scores the transaction across four dimensions and returns a composite. The score isn't advice — it decides the finality.

04 · Dispatch

Maestro reviews and dispatches. No agent can bypass another — compliance can't be skipped to reach execution; the sequence is the security model.

05 · Execution

Canto settles — atomic burn-and-mint PvP with an ISO 20022 memo, deterministic, no LLM in the loop. 387 ms later, it's final.

In detail · The six agents

One responsibility each.

Separation of concerns as a security model — each agent owns a distinct step in the settlement lifecycle, and none can act outside its role.

Maestro01
Orchestration

The brain. Interprets operator commands or autonomous mandates, decides the action, and coordinates every downstream agent.

POST /agent-think
Concord02
Compliance

Six deterministic checks before any movement: jurisdiction, bank status, balance, purpose code, sanctions, counterparty eligibility.

POST /compliance-check
Fermata03
Risk assessment

Scores counterparty, jurisdiction, asset, and behavior — the composite maps deterministically to a settlement finality.

POST /risk-score
Canto04
Execution

Atomic burn-and-mint PvP on Solstice with ISO 20022 (pacs.009) memo attached. Deterministic — no LLM in the loop.

POST /agent-execute
Cadenza05
Reversibility

Network supervisor. Monitors reversibility windows, detects anomalies, auto-reverses per rule, escalates uncertainty to humans.

POST /cadenza-monitor
Aria06
Operator interface

Natural-language config. Operators state intent in plain English; Aria translates it to parameter changes across the other five.

Chapter 02 · The gate

The score is the law.

0–30 · Low

Low composite risk settles instantly — straight to Canto, atomic PvP, 387 ms p99, no reversibility window.

31–50 · Medium

The gate diverts to the extended path: soft settlement with a 24-hour window. Cadenza watches before anything becomes final.

51–70 · Medium+

Higher medium risk holds a 72-hour window — and the parked principal isn't idle: yield accrues during the hold.

71–100 · High

High risk never self-executes. The transaction locks pending human review, with an AI-drafted briefing on the escalation dashboard.

In detail · Risk → finality

Deterministic by construction.

Fermata's composite maps to a settlement type with no discretion in the loop — the same score always produces the same finality.

Chapter 03 · The window

Soft settlement. Hard finality.

01 · Soft settle

At t+0 Canto burns the sender's deposit and mints the principal as a yield-bearing instrument, parked with the network custodian.

02 · Proof of claim

A T-bill-backed claim lands in the receiver's wallet as a pending balance — ownership intent transfers instantly; clearance waits.

03 · The watch

Cadenza monitors the window — anomaly scans against network rules, auto-reverse authority, escalation to humans when uncertain.

04 · Finalize or reverse

On all-clear both lockup tokens burn and the receiver's deposit mints — hard finality, yield to the network. On flag: automatic clawback.

01 / 04
Sender deposit — $8.1M USD-TDburn @ t+0

The originating tokenized deposit is burned the moment the extended path begins.

In detail · The economics

What sub-cent settlement unlocks.

Agent commerce isn't human transactions executed faster — it's a class of transactions the legacy per-message floor priced out of existence. The Solstice ledger settles nano-payments natively on-chain, gas-free, each carrying its own compliance record.

What this enables: per-call AI inference billing, machine-to-machine data marketplaces, real-time treasury rebalancing, atomic FX with no nostro/vostro pre-funding, autonomous procurement loops — everything the legacy $0.50–$50 per-message floor made impossible. Every nano-payment settles on-chain in a single slot with a structured ISO 20022 record, so machine-scale volume stays fully auditable.
Chapter 04 · The operator

Policy in plain English.

Operators don't file tickets. They tell Aria what posture they want, and the parameters change across all five agents — immediately, auditably.

In detail · Use cases

What ships first.

Three classes of workflow prioritized for the first institutional pilots.

01 · Treasury

Autonomous treasury rebalancing

Standing mandates drafted in Aria, executed by Maestro on market events. Treasurers set the policy; agents execute the rebalances — 24/7, across corridors.

02 · Inter-bank

Wholesale agentic payments

Two banks' Maestros negotiate settlement directly. Concord on both sides, Fermata scores the corridor, Canto settles atomically. Phone trees retired.

03 · Machine commerce

Sub-cent agent-to-agent commerce

Per-call inference billing, machine-mediated data marketplaces, autonomous procurement loops — nano-payments to $0.000001, each settled and logged on-chain at the cadence of the workload.
