Inputs (frozen)

These are the exact inputs the methodology saw at decision time. Pyth quotes, intrinsic snapshots, EWMA prior, threshold map — all serialized into the receipt for deterministic replay.

Download replay bundleHow to verify

Or verify right here — no install needed. This button re-fetches the replay bundle and recomputes the receipt hash in your browser using the same algorithm as the CLI.

On-chain commitment

Not anchored. On-chain SPL Memo commitment is cost-gated to high-severity transitions only — DEPEG, CRITICAL, and BLACK_SWAN — because each commit costs ~5,000 lamports and the operator wallet runs lean. The receipt is still cryptographically verifiable offline via the inputs above.

Pegana is a verifiable computation log for peg-state decisions. It is not SOC 2 compliance, not a regulatory audit, and not financial advice.
