● membrAIn audit verifier

Verify the audit chain yourself.

membrAIn signs every audit event with a per-account Ed25519 key and hash-chains them. This page verifies that chain entirely in your browser — the math runs locally, nothing is uploaded, and you don't have to trust membrAIn's infrastructure. Hand it to your auditor.

1 · Audit export (NDJSON)

Drop your .ndjson export here, or click to choose. (Portal → Audit → Export NDJSON)

2 · Account public key (hex)

Your account owner fetches this from GET /c/{account_id}/pubkey and gives it to you out-of-band.

Open-source verifier · runs offline · also available as a CLI: node verify-chain.js --file audit.ndjson --pubkey <hex> (download). Ed25519 verification uses your browser's built-in WebCrypto.
