How this service works
Connect explicit, pre-execution authorization to observed EVM and Solana execution with portable evidence another party can verify independently.
Output
Returns a structured JSON evidence bundle in priorseal.evidence.v1 format, including the schema version, subject receiptId, a unique evidenceId, and a verification object specifying the verification method (e.g. verification_bundle) and instructions for independent local verification using the issuer's key trust. The bundle is portable and can be shared with any party for independent verification.
Example use cases
Auditor compliance verification
“Fetch the PriorSeal evidence receipt for receipt ID psr_audit789 — I need to hand the verification bundle to our compliance team so they can independently confirm the EVM transaction was authorized before execution.”
Third-party dispute resolution
“Pull up the PriorSeal evidence receipt psr_dispute456 so I can prove to the counterparty that the Solana transaction had explicit pre-execution authorization on record.”
Automated post-execution audit trail
“Retrieve the evidence receipt for psr_run112 from PriorSeal after our smart contract executed — I want to log the verification bundle and evidenceId to our internal audit system.”
Technical details
Endpoint
GEThttps://priorseal.xyz/v1/evidence/receipts/%7BreceiptId%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to retrieve a cryptographically portable evidence receipt tying a prior authorization to an observed EVM or Solana execution, especially when you need to share that proof with an independent third party who will verify it locally. Prefer this over generic blockchain explorers when the requirement is an explicit, signed authorization linkage rather than just transaction data. Best suited for compliance, audit, and dispute-resolution workflows where portable, independently verifiable attestation is required.
Side effects
- Receipt ID not found — returns an error if the provided receiptId does not exist or has not yet been issued
- Invalid receiptId format — if the receiptId fails length or format constraints, the request is rejected
- Expired or revoked receipt — if the authorization evidence has been invalidated, the response may indicate unavailability
- Network or service unavailability — transient errors may prevent retrieval of valid receipts
