💳 How to pay for an Assisted Vault
Send exactly $350 worth of Bitcoin to our payment address. Include your account email in the transaction memo or send us an email after payment.
After we confirm your payment, your Assisted Vault will be activated within 24 hours. Subscription renews annually — we will email you a reminder 30 days before expiry.
⚠️ What happens if your subscription expires?
When your annual subscription expires, we will stop co-signing new transactions from your Assisted Vault. Your Bitcoin remains safe — it is still protected by your 2 hardware keys. You can still spend using your 2 keys together without our involvement.
To restore co-signing, simply renew by sending $350 in Bitcoin to the address above. We will resume co-signing within 24 hours of confirmed payment. We will always clearly state this policy — no surprises.
Frequently asked questions
What is the difference between Self Custody and Assisted?
In a Self Custody vault, you hold all 3 keys yourself on your own hardware wallets. Any 2 of your 3 keys can spend. In an Assisted vault, you hold 2 keys and we hold 1. We co-sign transactions only if they follow your rules (spending limits, whitelist, etc.). If we are ever unavailable, your 2 keys can still spend together — you are never locked out.
Can Bitcoin Policy Studio steal my Bitcoin?
No. We only hold 1 of 3 keys. Moving funds requires 2 signatures. We can never initiate or complete a transaction on our own — we can only co-sign or refuse to co-sign transactions that you initiate. Your 2 hardware keys always give you majority control.
What hardware wallets are supported?
Ledger and Trezor connect directly in your browser via USB — no manual steps. Coldcard is supported via a file export from the device's MicroSD card (Coldcard is air-gapped by design and does not support USB connections). Other devices can be added by pasting an xpub.
Do you use Bitcoin Core or third-party services?
We run our own Bitcoin Core node for transaction validation and broadcasting. We do not rely on third-party services for our core infrastructure. The Timelock and PSBT tools use mempool.space for UTXO lookups and broadcasting — this is optional and only used when you choose to broadcast.
How does inheritance work?
You set an inactivity period (e.g. 365 days). If you have not used the vault for that long, your designated heir can request our co-signature. We verify the inactivity period and co-sign the inheritance transaction. You can reset the timer at any time by making any transaction or logging into your account.
What if this website disappears?
For Self Custody vaults, your 3 hardware keys are all you need — you can use Sparrow Wallet or any multisig-compatible wallet to spend. For Assisted vaults, if we disappear your 2 hardware keys can always spend together without our key. The Timelock tool only requires your 24 seed words — no website needed to claim funds.
Is there a monthly payment option?
No. We charge $350 per year per Assisted Vault, paid in Bitcoin. We chose annual billing to keep things simple and to avoid monthly payment friction. Bitcoin payments are final — no chargebacks, no payment processors.
