Public chains are glass houses.

Every salary, invoice and treasury move you make on-chain is readable by anyone, forever. Competitors map your payroll. Bots watch your treasury. Your team sees each other's pay.

Velum encrypts every field.

Amounts, names and memos are encrypted on your device before they ever reach the chain. Keep scrolling and watch it happen.

  • Shielded balancesHold USDC and USDT where only you can read the number.
  • Private transfersSend to anyone, on the chain they use, without a public trail.

Proof without exposure.

A zero-knowledge proof shows the network that every payment is valid and fully backed, without revealing a single number. The chain checks the math, never your data.

Show exactly who you choose.

Hand your auditor, regulator or board a view key. They see what you allow, for the dates you allow. Everyone else sees silk.

Private isn't hidden from the law.

Selective disclosure

View keys for auditors and regulators, scoped by account, date and type.

Screened deposits

Every incoming transfer is checked against sanctions lists before it's shielded.

Travel Rule ready

Counterparty details travel with the payment, encrypted, to the institutions that need them.

Bank-grade controls

Hardware-backed keys, approval policies and a full audit trail for every action.

Private payments in a few lines.

Payroll platforms, wallets and treasuries use the Velum SDK to add shielded payments without running any cryptography of their own.
