RLUSD Evidence Pack

Verifiable data infrastructure for stablecoin reserve attestations

schema: evidence_pack_v3.2 guard: OK on-chain: XRPL (active)

Evidence Pack ⬡ Polygon TX ◈ XRPL TX

Important Disclaimer

Data infrastructure only. Not an audit, legal advice, or certification.
Proofs reflect the committed dataset referenced by snapshot/content hash.
No partnership or endorsement implied with any third party.

How It Works

Snapshot Creation

RLUSD reserve data is parsed from public attestation reports and stored with a SHA-256 content_hash.

Hash Computation

A deterministic SHA-256 content_hash is computed from the snapshot data. This hash uniquely identifies the dataset.

On-Chain Anchoring

The proof hash and bound_snapshot_hash are anchored to XRPL Ledger (memo transaction). Polygon smart contract anchoring planned.

Evidence Pack Assembly

All components are bundled into a single, verifiable JSON response with hash-binding verification.

Verify in 30 Seconds

Copy and run these commands to verify the evidence chain:

1. Get Guard Status

curl -s https://api.feedoracle.io/api/v3/rlusd/cci | jq

2. Verify Hash Binding

curl -s https://api.feedoracle.io/api/v3/rlusd/evidence/latest | \
  jq '{snap: .snapshot.content_hash, chain: .integrity_proof.bound_snapshot_hash, match: (.snapshot.content_hash == .integrity_proof.bound_snapshot_hash)}'

3. Check On-Chain Attestation

curl -s https://api.feedoracle.io/api/v1/zk/attestation/latest | jq '{threshold_passed, block_number, tx_hash, explorer_url}'

What Is Proven / Not Proven

✓ What the Evidence Pack proves

Data snapshot has a deterministic hash
Hash-anchor proof is bound to that specific hash
Hash proves data integrity at anchor time
Attestation is anchored on XRPL (Polygon planned)
Hash chain is intact (no tampering)

✗ What it does NOT prove

Accuracy of upstream source data
Regulatory compliance status
Financial audit certification
Real-time reserve status
Any endorsement or partnership

Integration Playbooks

DeFi Protocol

Call checkThresholdPassed(maxAge) on the Polygon contract before allowing withdrawals or minting.

Dashboard

Poll /api/v3/rlusd/cci every 5 minutes and display the status badge.

Alerting

Monitor guard status changes. Alert on WARNING or CRITICAL with reasons array.

Compliance

Store evidence pack responses as audit trail. Hash-binding proves data integrity.
