Collaborative security uses a 2/3 multisignature vault with three or more key holders. Two signatures are required to move funds, so no single person can compromise the Bitcoin. You retain day-to-day control while The Bitcoin Adviser and a vault partner provide redundancy.

We work with Theya and Unchained, both of which provide institutional-grade infrastructure, audits, and distributed vault operations. We evaluate partner fit during onboarding.

We build redundancy into the vault. If a signer is unavailable, the remaining two can approve a transaction after verifying identity through documented procedures. We also maintain sealed backup keys in geographically diverse, tamper-evident vaults.

We schedule orientation sessions when there’s a good reason—new signers, major life events, hardware changes, or whenever you’d simply like a refresher. No automatic calendar required.

Clients receive a dedicated adviser, encrypted communication channels, and 24/7 emergency escalation paths. We respond to critical requests within two hours and schedule proactive briefings each quarter.

We run a guided session covering device setup, security posture, and approval workflows. The new signer completes a small walkthrough transaction, and we update the documentation so all parties know how to reach them.

Yes, provided they meet security standards and compatibility requirements. We support multiple hardware vendors and can recommend upgrades when necessary.

Because the vault requires two signatures, losing one device does not stop operations. We follow the incident response plan: verify identity, revoke the compromised device, provision a replacement, and update backups.

Your vault is billed every 90 days at 1% annualised (0.25% per quarter). You'll receive an email alert, click "Pay Invoice" in your Theya wallet, sign with your key, and we counter-sign to complete the payment. The process works just like a withdrawal transaction. See our onboarding guide for detailed steps, or Theya's step-by-step payment guide for instructions on paying via Theya Vault or external wallet. See full pricing details →

You can track transactions using tools like mempool.space. Simply paste your transaction ID (TXID) to see its status, confirmations, and fee information. We often include direct mempool.space links when we move funds for you so you can see exactly what we're seeing.

Our transaction tracking guide also covers transaction signing protocols, including how we handle withdrawals of different sizes and processing timeframes.

Withdrawals follow the same 2/3 multisig flow: you initiate the withdrawal in your Theya wallet, sign with your key, which triggers us to counter-sign, and the transaction broadcasts. You can move Bitcoin in and out of your vaults as often as you want with no penalties.

Transaction signing protocols: For withdrawals over 0.1 BTC, we will endeavor to check with you that everything is ok before counter-signing. If you're planning a large withdrawal or need one urgently, reach out to your adviser via email and cc sign@thebitcoinadviser.com to notify us. This helps us process your request in a timely manner.

Processing timeframes: We endeavor to sign transactions within 48 hours and sooner if possible. This is long-term cold storage, and rush transactions are often a red flag that something is wrong—we prioritize fund safety first. Learn more about transaction tracking and signing protocols.

The simplest way to consolidate UTXOs in a 2/3 multisig vault is to send your vault balance back to itself. This creates a single new UTXO from all your existing ones. We monitor your UTXO health and guide you through this simple process when needed. Learn more in our UTXO Management guide.

Two-Factor Authentication (2FA) is critical. Your email account is often the gateway to your Bitcoin holdings—if someone gains access to your email, they could potentially reset passwords for exchanges, wallets, and other services. We strongly recommend enabling 2FA on all accounts, especially email.

Hardware security keys (YubiKey) provide the strongest protection. Unlike SMS or authenticator apps, hardware security keys can't be phished or intercepted. They're physical devices that you plug in or tap to authenticate. We recommend using a YubiKey 5C NFC for securing email, cloud accounts, and exchange access.

See our comprehensive Security Centre for the YubiKey Security Guide with setup instructions, best practices, and why hardware keys are superior to SMS or authenticator apps. This is especially important for accounts connected to your Bitcoin holdings.

Most clients are onboarded within one to two adviser sessions once hardware is in hand. The Theya wallet setup itself takes about 15 minutes during your onboarding call. Transfers depend on exchange verification and bank wire timing. See our complete onboarding guide for the full process.

Theya is the collaborative multisig wallet software we use for all new clients. It works on iOS and in web browsers, making it the easiest option with the simplest onboarding process. Theya provides institutional-grade infrastructure and supports the 2/3 multisig setup that forms the foundation of collaborative security.

You'll need a hardware signing device (Trezor is recommended), secure email access with 2FA enabled, and a computer or iPad for screensharing. If you plan to use an iPhone, the Theya app can serve as an additional software key. Have your exchange account ready if you're planning to transfer funds.

Security recommendation: We strongly recommend securing your email with a hardware security key (YubiKey) before onboarding. Your email is often the gateway to your Bitcoin holdings, and hardware keys provide the strongest protection against phishing and account compromise. See our Security Centre for the YubiKey Security Guide with setup instructions.

See our onboarding guide for the complete prerequisites checklist.

Yes. If you already have a Trezor, Ledger, Coldcard, or Foundation device, it can be used as a key for multisig in Theya. We'll help you configure it during onboarding. You don't need to buy hardware through us—purchasing directly from Trezor or reputable resellers works just as well. See our Security Centre for the Hardware Wallet Guide with setup instructions and security best practices.
