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.

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.

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
AI agents do the work. DefaultVerifier gives you the receipt.
Signed receipts. A proof seal derived from the receipt’s own signature.
A public registry anyone can verify, no account needed.

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.
Agent ecosystems are converging on the same realization:
confidence doesn’t scale.
verification does.
Independently verifiable receipts for agent actions.
If it matters — verify it.

Heurist x @awscloud
AWS just shipped AgentCore Payments with @coinbase and @stripe
We're proud to build agent-native finance on Bedrock at Heurist.
You didn't lose your money.
It was taken slowly enough that you didn't notice.
Inflation. Fees. Custodial spread. Year after year, your savings bought less while your bank reported record earnings.
The game was rigged. Now there's finally a way out.
We bought the rarest sat for 33.3 BTC.
We etched the most unique Rune on it.
We airdropped it to the entire Bitcoin community.
Now we’re cooking the next phase.
Notifications on.
@allnostru@brian_armstrong SAR determines if the agent actually delivered what was specified in the spec. If yes, Pass. If no, Fail. If neither, Indeterminate. If it matters—Verify it!
