Mobile Vault Spend: Streamline transactions directly from your iOS app

Vault transactions just got easier. 

New mobile vault spend features are now available on iOS, giving you more flexibility to manage and approve bitcoin transactions from your mobile device—all while maintaining the multisig security that protects your vault.

With these updates, you can move vault transactions forward even when you’re away from your desk:

• Easily draft a transaction from your vaults directly in the iOS app
• Request connections, key agents, and Unchained to sign from the iOS app
• Record video verifications and use new passkey verification on requests
• Use business approver flows integrated into the new transaction workflows

Managing collaborative custody means balancing control, coordination, and security. These new mobile features bring all of that together in a streamlined experience. 

Draft transactions anytime, anywhere

Prepare bitcoin transactions directly from your vaults on iOS. Start a draft, confirm details, and come back to complete it when ready. Whether you’re coordinating with a business partner or moving funds from cold storage, securely manage your bitcoin transactions with ease.

Request signatures with confidence

You can now send signing requests to your connections, key agents, and Unchained directly from the iOS app. These workflows simplify coordination across multiple signers, ensuring that vault spending remains protected, even when approvals come from different locations.

Enhanced verification tools

Our new updates allow video verification and additional passkey authentication requests to be satisfied on your iOS device. Together, these features create greater transparency and stronger assurance that every transaction request is authorized and validated by the right person.

Integrated business approvals

For Unchained business clients, approver flows are now built directly into the mobile transaction workflow. Approval requirements are automatically applied before bitcoin moves, ensuring safety is not sacrificed for convenience.

Built for security and simplicity

Every new iOS feature continues our core mission: helping clients maintain control of their bitcoin through collaborative custody while improving everyday usability. Now, Unchained clients can draft transactions, coordinate signers, and complete verifications with a few taps.

Mobile vault spend updates are available now for iOS users. Android support will follow in a future release. To learn more, explore the new vault spend features directly inside your Unchained mobile app.
