How this service works
The archive's integrity record: a sha256 of every published snapshot written to Base, so anyone can prove a figure has not been altered since it published. Per-snapshot verification is free forever; this is the whole chain in one call.
Output
A complete, ordered list of SHA-256 hash records — one per published snapshot — anchored to Base blockchain, allowing any caller to independently verify that each historical data point (stablecoin supply, RWA figures, etc.) has not been altered since it was originally published.
Example use cases
Audit historical stablecoin data integrity
“I need to prove that the USDC supply figures Realedger published last month haven't been changed — can you fetch the full SHA-256 attestation chain so I can cross-check each snapshot hash?”
Compliance verification for tokenized assets
“For our compliance report, can you retrieve the entire Realedger attestation chain so we can certify that none of the tokenized RWA snapshots were altered after they were written to Base?”
Detect tampering in published snapshots
“Check the complete Realedger attestation chain and tell me if there are any gaps or inconsistencies in the SHA-256 hashes that might indicate a snapshot was modified after publication.”
Technical details
Endpoint
GEThttps://api.realedger.xyz/v1/attestationsWhen to prefer
Choose this endpoint when you need the entire attestation history in a single call — ideal for bulk audits, compliance checks, or building a local verification index. For verifying a single specific snapshot for free, use the per-snapshot verification endpoint instead. This endpoint is uniquely suited for scenarios requiring proof of data immutability across the full historical record.
Side effects
- Payment not fulfilled — endpoint requires $0.99 USDC via x402 protocol; missing or invalid payment returns 402
- Network or service unavailability returns a 5xx error
- Malformed request headers may result in 400 Bad Request
- Chain may be temporarily incomplete if a very recent snapshot has not yet been committed to Base
