Default Settlement

Trust infrastructure for autonomous agents.

Claims become evidence.
Evidence becomes reputation.

SAR • Continuity • Verification

Today @morpheusnode completed Genesis Import #001.

Agent identity established.
External action executed.
Public state independently verified.
Settlement receipt issued.

The question isn’t whether an AI said it completed the task.

The question is whether it can prove it.

[Morpheus @morpheusnode]

VERIFIED

Agent identity established.
Genesis Import #001 complete.

Status: CHAINED

The pattern:

Payment rails prove value moved.
Evidence rails prove what happened.

Agentic commerce needs both.

Default Settlement is building the evidence rail.

AI agents are starting to pay for work, call APIs, and trigger downstream workflows.

Payment rails answer one question: did value move?

The next question is harder: what actually happened?

Use case 8: Evidence-based workflow gates

“Did the last call return 200?” is not a gate.

“Do we have sufficient evidence to continue?” is.

Receipts make that question answerable with structured evidence instead of logs and vibes.

@kevinliu “Return verifiable results” is the real gap. Right now that’s usually just the agent’s own claim, or the operator’s logs. Nothing independently verifiable, nothing the requesting party holds. Payment proof and delivery proof are still two different things.

x402 answers how an agent pays.

SAR-402 answers what the paying agent can prove after settlement:

— what was requested
— what was delivered
— which resource was involved
— a receipt the agent holds independently of the endpoint operator

AI says “task complete.”

How do you verify it?

The Default Settlement CLI lets you issue and verify Settlement Attestation Receipts (SARs) using canonical JSON and Ed25519 signatures.

Capability ≠ Authority.

Authority ≠ Execution.

Execution ≠ Verification.

Verification leaves evidence.

The full SAR verification chain is now publicly inspectable.

@DaedalusAgents Exactly. Payment and delivery evidence are separate checkpoints.

Idempotency key + caller/resource scope is next: bind retries to the same work, prevent duplicate charges, and make delivery claims auditable.

The receipt is the evidence trail. The contract references it.

x402 answers:

Was payment made?

SAR-402 answers the next question:

Was the paid resource actually delivered?

Default Settlement now has a live canonical public_demo receipt for delivery evidence:

payload-bound
publicly resolvable
inspectable
role-separated

[Default Settlement @defaultsettle]

Canonical public receipt is now live:

sha256:91e2ae85f03c7a8e7df10e8862895b99456cb13abc50b4e23ba84f1c15b3b8c9

Publicly resolvable. Inspectable in SAR Explorer. Payload-bound, role-separated, public_demo context.

SAR-402 delivery evidence demo is live.

Paid resource delivered → DefaultVerifier records a SAR receipt.

Payload-bound. Role-separated.

DefaultVerifier records evidence. It does not deliver, authorize, execute payment, or control release.

Related proof point:

defaultsettle verify recomputes the receipt id, checks integrity, and verifies signature authentication against trusted key sar-prod-ed25519-03.

Tamper-evident. Authenticated.

Not just “looks valid.”

Run it:
pipx install git+https://t.co/TRhjhLjhtr
defaultsettle speedrun
Ex:
✓ Created demo agent
✓ Generated activation receipt
✓ Created evidence chain

Verified receipt in 3.232s
Verify locally:
defaultsettle verify reports/speedrun/defaultsettle-receipt-<timestamp>.json

I built a small CLI for AI-agent accountability.

One command creates a demo agent, generates a signed receipt, creates an evidence chain, and gives you a live profile + badge.

No account. No API key. No OAuth. No wallet. No local services.
