We're building a self-custodial Bitcoin neobank. Part of that mission is making sure that your Bitcoin savings are well-protected in your self-custody. Today we're partnering with BitVault, and every wave.space user gets 15% off any BitVault plan, plus a free hardware wallet (Keystone 3 or Jade Plus) on the 1-year plan or two on the 2-year plan. This product is currently available only to iOS users.
Set the vault up once, point wave.space LINK at it, and every euro you send from your bank arrives as Bitcoin inside a vault protected against thieves and kidnappers.
What a BitVault vault gives you
Your vault is a 2-of-3 multisig built with Miniscript. Two of the keys sit on hardware wallets you hold, air-gapped, signing by QR code. The third is BitVault's co-signing key, which cannot move a single sat on its own. BitVault never touches your Bitcoin.
On top of that sit two separate protections:
Delayed transactions stop unauthorised spending. Every transaction leaving the vault waits before it settles, between 2 hours and 15 days, on a delay you choose. The moment one is initiated you get a Telegram message. If you did not start it, you cancel it, and your Bitcoin stays exactly where it is. A stolen phone, a cloned SIM, a signing request that looked legitimate at 2am: each of them now has to survive a countdown you can watch and stop.
The on-chain timelock answers the wrench attack. The spending path you can use without BitVault at all carries a one-year absolute timelock, written into the Bitcoin script itself. Consensus rules enforce it, so nothing in that vault can be handed over on the spot. No key, no service and no pressure in a room shortens it. Coercion works on people who can act immediately, and your vault takes that option off the table.
One guards against someone who got hold of your keys. The other guards against someone who got hold of you.
It is the right place for the Bitcoin you have no intention of spending this year.
How to setup your BitVault with wave.space?
Step 1: Activate BitVault (iOS only)
- Claim the offer. Login to your account on wave.space and click on a new feature called “Vault” to claim your offer. The 1-year plan includes one hardware wallet, the 2-year plan includes two, and your 15% discount applies to both.
- Choose your devices. BitVault emails you to select from the supported hardware wallets: Keystone 3 Pro (Bitcoin-only) and Blockstream Jade Plus. Mix them if you want two vendors on the door.
- Redeem your vouchers. Confirm your choice and BitVault sends voucher codes to redeem directly with the manufacturers. The devices ship to you.
- Download the BitVault app from the iOS App Store.
- Build the vault. The app walks you through adding both hardware wallets and verifying ownership. Your seed phrases and private keys stay on the devices throughout.
- Set your delay. Pick anything from 2 hours to 15 days. Longer delays give you more room to catch something wrong. Shorter delays give you faster access when you genuinely want to move funds.
Your vault is live. Copy its receive address.
Step 2: link it to your wave.space IBAN
- Open wave.space and go to LINK.
- Paste your BitVault receive address and name the link, for example "Vault".
- wave.space issues you a dedicated vIBAN in your own name, bound to that address alone.
- Send euros to it. Any EUR that lands on that IBAN is converted and sent on-chain to your vault automatically.
That's the whole setup!
Why buying straight into the vault changes things
Set a standing order from your salary account on payday. Every month, euros leave your bank and Bitcoin arrives in a vault with a time lock on it.
Euro-cost averaging usually breaks for one of two reasons. People forget to buy, or the move into cold storage keeps getting postponed to next weekend. A standing order handles the first. Buying straight into the vault handles the second.
This is the strongest way to stack long-term savings on wave.space. Keep a spending balance for your wavecard and your Lightning payments. Send everything else straight to the vault and let the delay guard it.

The discount is live now for wave.space users. Pick your plan, choose your hardware wallets, and have your vault running before your next payday.
