Receipts

Understand and verify Prism receipt fields across IPFS, x402 payment, Arc validation, and local CLI output.

A receipt is the evidence bundle behind a Prism Report. It should let another developer answer: what trace was validated, who paid for validation, what verdict was produced, and where the public proof lives.

Canonical judge receipt bundle

This is the smallest bundle a reviewer can use to verify the current product path:

Proof	Link or value
Canonical trace report	trace report
Trace IPFS CID	`QmNzqnPEEQUMn3GMbiEZANpKXZRPmTHxVwt5nNevR8iXt8`
Trace content hash	`0x1a750011608a7480e9cb11f1d20587e32efb7a7dd433b85820f0dbfcdee19fdb`
Dashboard x402 payment tx	BaseScan tx
Canonical trace Arc validation request	Arc tx
CLI x402 payment tx	BaseScan tx
CLI verdict IPFS CID	IPFS verdict
CLI payer wallet	`0x229d65c16eb0386ac9a759625836e7d2b9831c3e`

Circle is the payment and wallet boundary; Arc/ERC-8004 is the validation receipt layer where tx hashes are present; IPFS is the content-addressed trace/verdict layer. The canonical trace has an Arc validation-request tx; validation-response txs are shown only on reports where validation_arc_tx is present. Prism CLI never reads private keys and local receipt files never store raw X-PAYMENT headers.

Canonical CLI paid receipt

The first live CLI paid validation receipt is checked into the repository:

docs/demos/cli-paid-validation-20260516T214837Z.md
docs/demos/cli-paid-validation-20260516T214837Z.json

It paid 0.01 USDC on Base Sepolia and produced verdict 50 WARN for the canonical demo trace.

CLI receipt files

prism demo writes two local files:

.prism/receipts/<timestamp>-dry_run-<trace>.json
.prism/receipts/<timestamp>-dry_run-<trace>.md

Paid demo receipts use paid in the filename. The receipt files do not contain the raw X-PAYMENT header.

Key fields

Field	Meaning
`trace_uri`	IPFS URI for the trace being validated.
`trace_hash`	0x-prefixed content hash supplied to validation.
`quote`	x402 payment requirements.
`validation_result.payment_tx_hash`	Base Sepolia payment transaction when paid.
`validation_result.tx_hash`	Arc validation response transaction when available.
`validation_result.ipfs_cid`	Verdict content CID.

Verify public report

uv run prism report d6cdd60f-f5e0-43ab-ba2d-7dcab76a8e24 --json

Compare the report's receipt fields with the local demo receipt.

Verify payment and Arc transactions

Use the explorer URL associated with the network in the receipt. Base Sepolia x402 payment transactions prove payment for validation. Arc validation transactions prove the validation request/response was anchored against deployed Arc registries.

Prism does not deploy custom Solidity contracts for this flow.
