Your coins, working for you

Bitcoin, held
on your terms.

Cobault makes it easy to set up and use native Bitcoin multisignature vaults, collaborate with people you invite, and get the most from your BTC holding. The Bitcoin network does the work; you keep your keys, and can recover every vault without Cobault.

No wrapping. No bridging. No custody transfer. Built by a team who have run markets across financial services and blockchain.

Always your coins

Every vault is its own Bitcoin address. Never wrapped, bridged, or pooled.

Spends need your quorum

Only the participants you chose can move funds — on the quorum and terms fixed when the vault opened.

No Cobault key in your vault

Policy vaults (coming soon) will add a verifier key we operate; it co-signs only spends matching your rules, and your quorum always has control.

Products

Shared vaults are live today.

Everything Cobault builds runs on the same non-custodial multisig vault. Our vision is to enable licensed partners to offer wealth strategies through it. No such product is currently offered — join our waitlist to be the first to hear when we do. We hope to share more very soon.

Live now Shared vaults

Hold Bitcoin with others

Split keys across a partner, your family, or your business — and remove any single point of failure in how your Bitcoin is held.

Peer-to-peer shared vaults

Invite a quorum of participants — we provide a convenient interface for native BTC vault setup. Or create a vault with two or more keys you control yourself, protecting against compromise or loss of any one key.

§

Policy vaults Coming soon after launch

In addition to invited participants, select an approve-list and spend-limit policy to stand in for one member of your quorum for convenience. Your user quorum always has control.

Built-in recovery

Lose a key and the remaining participants can restore access, subject to your quorum.

Our vision Wealth strategies

Wealth strategies from licensed partners

We plan to work with licensed third parties, enabling them to offer Bitcoin wealth and asset-management strategies through the Cobault multisig vault system. No such product is available today, and nothing on this page is an offer of yield, a rate, or a return.

How it works

Open a vault in minutes.

Bring a key

Ledger, web wallet by MetaMask (Web3Auth), or our browser key agent. Your key is generated and held on your side — Cobault's backend never sees private key material.

Open a vault

Choose your collaborators and your quorum. Once every participant has accepted, the vault is sealed and its address is fixed — a native Bitcoin multisig, visible on-chain from day one.

Operate and withdraw

One participant proposes a spend; the others review and sign. When your quorum is met, the transaction broadcasts to the Bitcoin network. In a policy vault (coming soon), the verifier co-signs only within your rules.

Why Cobault

How Cobault compares with other multisig options

Multisig is the right way to hold Bitcoin with others. Until now the choice has been between expert desktop tooling you coordinate yourself and managed subscriptions where the provider holds a key. Cobault builds the coordination in — and in a standard vault holds no key at all.

For institutions

Managing significant Bitcoin holdings?

We work with family offices, corporate treasuries, and funds to structure multisig positions at scale — shared custody across the participants you choose, with policy vaults (coming soon) adding spending limits and approve-listed destinations enforced in the vault itself.

FAQs

Frequently asked questions

Who holds my Bitcoin?

You and the participants you choose. Every vault is a native Bitcoin multisig; each participant's key is generated in their own browser from a seed phrase only they hold. In a standard shared vault Cobault holds no key and cannot move your Bitcoin under any circumstances. In an optional policy vault (coming soon after launch), a verifier service we operate will hold one key in a secure enclave and co-sign only spends that match your policy.

What happens if I lose my seed phrase?

It is unrecoverable — by Cobault, and by the other participants. Depending on your quorum, one lost key can permanently freeze the vault for everyone in it. Back up your seed phrase before you deposit anything.

Can other participants spend without me?

If the quorum you configured can be met without your key, yes. That is how multisignature works: choose your participants and your quorum accordingly.

What happens if Cobault disappears?

Your vault is an on-chain Bitcoin multisig, and you can export a vault specification containing everything needed to reconstruct and spend it with standard Bitcoin tooling. If we disappear, your Bitcoin does not.

Is vault activity private?

No. The vault address, quorum, deposits, spends, and which participants signed are recorded on the Bitcoin blockchain — public and permanent. Within a vault, participants see each other's display names, invitation email addresses, and public keys.

What about yield?

Our vision is to work with licensed third parties, enabling them to offer Bitcoin wealth and asset-management strategies through the Cobault multisig vault system. No such product is available today, and nothing on this site is an offer of yield, a rate, or a return. To find out more, join our waitlist.

What do I need to start?

A Ledger, web wallet by MetaMask (Web3Auth), or our browser key agent, which generates and holds your key locally. Back up your seed phrase before depositing.

Who operates Cobault?

Cobault is a business name of Bluemetal Services Pty Ltd (ACN 701 330 627), an Australian company and wholly owned subsidiary of Chain Capital Technologies Ltd (England and Wales). Bluemetal builds and runs the platform; it holds no customer Bitcoin.

Is Cobault regulated?

Bluemetal Services Pty Ltd is not licensed as a financial services provider and does not provide financial product advice. Cobault is software for coordinating Bitcoin multisignature wallets: we do not take custody, we do not exchange Bitcoin, and we offer no investment, yield or return. Nothing on this site takes account of your objectives, financial situation or needs.

What is the difference between cobault.net and cobault.io?

cobault.net is the company: who we are, how the architecture works, and why. cobault.io is the product platform, and wrap.cobault.io is the app itself.
