Cairn Vaults

Private settlement for serious businesses.

Cairn Vaults pair instant onchain settlement with the confidentiality and built-in controls your finance team actually needs.

Use cases

Enterprise flows, uncompromised.

Supplier payments

Pay vendors and counterparties without publishing your supplier list to a public chain.

Payroll & payouts

Run onchain payroll without broadcasting what every employee or contractor earns.

Treasury operations

Move stablecoin balances between corporate accounts, custodians and counterparties privately.

Issuer corridors

Issue and settle a token where individual balances and flows aren’t publicly observable.

Cross-border remittance

Verified corridors where the sender, recipient and amount are never exposed to the world.

Brokerage & settlement

Settle between disclosed counterparties without leaking trade flow or position data.

Features

Purpose-built for the modern enterprise.

Confidentiality

Public chains expose every transfer. Cairn Vaults keep the flow private.

Controls

Private to the world, legible to your auditors and your regulator.

Composability

Fully composable with the rest of Cairn. Move funds in a single transaction.

Configurability

Shape each vault around the way your business actually settles.

How it works

Keep the business private while money moves onchain.

Settles on Cairn

Funds anchor directly to Cairn through one onchain contract, settling on the network itself rather than a side chain.

Unlinkable transfers

Deposits hide the recipient, withdrawals hide the sender, and the two never join up on the public ledger.

Full composability

Composable with the rest of Cairn: move funds in or out and act on them inside a single transaction.

Compliance compatible

Verification stays enforced at the vault level, through Cairn Verify or a provider you already run.

Powered by Cairn Cloud

Cairn Managed

The fastest path to private settlement. We run the vault and the compliance stack, so you get confidentiality without standing up infrastructure.

  • Atomic composability. Move money in or out in the same transaction as any onchain action, like pay-and-settle or withdraw-and-swap.
  • Confidential by default. Senders and recipients stay hidden on the public chain; balances and transfers stay inside your vault.
  • Compliance handled. Verification through Cairn Verify, sanctions screening built in, and licensing carried by us.
  • Nothing new to stand up. We operate the vault and expose it through the Cairn developer platform, so your team ships without new infrastructure.
Self-managed

Partner Vault

Your vault, your controls. Run your own portal and vault with your own setup: self-custody, your verification provider and your own policies.

  • Everything in Cairn Managed, plus
  • Self-custody. Hold funds in a dedicated contract for your business. Open, auditable controls; you keep the keys.
  • Bring your own compliance. A dedicated contract gated by your requirements, holding only your customers’ funds.
  • Auditable history. Every change is proven onchain and privately. Publish the rules and anyone can verify them.
  • Custom vault logic. Write programs that operate on your vault and prove they ran correctly without revealing anything.
