Compliance viewing keys
Privacy and accountability aren't opposites. Murk lets you prove your activity to an auditor, employer, tax advisor, or regulator without giving up control of your funds.
What a viewing key does
Your viewing key decrypts your notes. Anyone holding it can:
- see every note you received and its amount and token,
- reconstruct your private transaction history.
Anyone holding it cannot:
- spend, move, or freeze your funds,
- recover your spend key,
- read any other user's activity.
That boundary is cryptographic, not a policy: spending needs the spend key (to open your owner key and form nullifiers), which the viewing key can't produce; and the viewing key is a one-way hash of the spend key, so it can't be inverted.
How to export it
- Unlock your wallet.
- Go to Settings → Compliance.
- Read the warning, tick the acknowledgment, and reveal the key (
mvk1:…). - Copy it and share it with your trusted party over a secure channel.
⚠️ Warning: Treat a viewing key like a secret. Anyone with it sees your entire private balance and history. Only share it with a party you trust, and only over a secure channel. Murk auto-hides the revealed key when you click away.
How an auditor uses it
With your viewing key and your public owner key, an auditor runs a view-only scan: decrypt every note blob on-chain, keep the ones that belong to you, and read the amounts. They see your full holdings and receipts — read-only, spend-nothing.
Why this matters
This is "pragmatic privacy": strong default confidentiality with selective, user-controlled disclosure. You decide who audits you, and you never surrender custody to do it.
