One settlement. Both legs, or neither.
COSMO demonstrates bonded, accountable execution on Supra Mainnet through an RFQ-based proof. The RFQ is the mechanism that exercises it — not COSMO's product identity.
An RFQ — request for quote — is a two-party trade: a taker asks for a price, a maker quotes one, and the two assets change hands.
The settlement is atomic: both legs move in a single transaction, or the whole thing reverts. There is no in-between state and no moment where one side is exposed.
That is the mechanism — atomic settlement, enforced on-chain. Below is a real one, replayed step by step from a controlled Supra Mainnet RFQ proof with separated roles: a SupraOS-side requesting agent (the demand side) initiates the RFQ, Kahless represents the Maker side, and behind Kahless K1 acts as the bonded Maker-Operator. COSMO locks, checks and settles the exchange atomically on Supra Mainnet. The founder no longer signs the Maker leg — this proves role separation and the settlement mechanism, not market activity.
Community Maker Proof — Live on Supra Mainnet
On 2026-07-04 the first community maker (M2, Slot 1) quoted, funded and settled a complete agent-native RFQ settlement on Supra Mainnet — running on COSMO's bonded execution infrastructure, inside the hard 60-second quote window. The maker-execution primitive now has its first non-founder proof.

Post-verify accounting exact: taker −1.0 tINTEST / +0.997 wCOSMO · M2 +1.0 tINTEST / −0.997 wCOSMO. Operator bonds untouched (200M total / 100M available to M2). Peg invariant holds. Quote-server gate enforced before signature.
Maker slots
| Slot | Status | Note |
|---|---|---|
| Founder / K1 | Proven | Separated-operator round-trip (D-14, 2026-06-24) |
| M2 Slot-1 | Proven | Phase 6 settled 2026-07-04 — first community maker |
| Slot 2 | Reserved | Phase 7 passed 2026-07-07 — opens against the first committed external operator |
Phase 7 — observation window
Passed- Completed 2026-07-07 without incident — 72 hours of daily read-only checks on peg, bonds and gate logs.
- Decision taken (one variable at a time): an anti-spam request fee is now active on the RFQ engine.
- Slot 2 stays a prepared governance option — it opens against the first committed external operator, not on a timer.

The roles
SupraOS asks. Kahless quotes. COSMO settles. Supra finalizes.

Requesting Agent
A SupraOS-side demand agent that starts the RFQ. Represents the demand side — the future SupraOS demand surface.

Kahless · Maker-Agent
Represents the Maker side and returns the quote.
K1 — the bonded Maker-Operator behind Kahless. K1 executed the Maker side in this Mainnet proof; its bond stayed untouched.
COSMO
COSMO's execution and accountability layer. It locks, checks and settles the exchange atomically — it is not the Maker or the requester.
Supra
The Mainnet finality layer. Supra finalizes the trade on chain 8.
