Manage vaults, trade, and sign transactions.
Built on multisig. Powered by hardware wallets.
Why Desktop
A native desktop experience designed for the security, speed, and reliability that managing significant bitcoin holdings demands.
Persistent, stable connections to Ledger, Trezor, COLDCARD, and Foundation devices. No flaky browser USB — the desktop app maintains a direct, reliable link to your hardware wallets for seamless transaction signing.
Every transaction is verified before you sign. See exact outputs, fee rates, and destination addresses across all your vaults — powered by local PSBT parsing with no data leaving your machine.
Manage all your vaults — personal, IRA, business, and inheritance — from a single desktop view. Monitor balances, key health, and transaction history in real time.
Buy bitcoin through the integrated trading desk and have it land directly in your multisig cold storage vault. No exchange accounts, no withdrawal delays, no counterparty risk.
Monitor your bitcoin-backed loans, track collateral health, and manage repayments from a dedicated loan dashboard. Set alerts for margin calls and automate monitoring.
The desktop app continuously monitors the health of your hardware wallet connections and key configurations. Get proactive alerts if a key needs attention or replacement.
Collaborative Custody Architecture
The Unchained Desktop App is built around the 2-of-3 multisig collaborative custody model. A central vault holds your bitcoin secured by three keys, with two required to authorize any transaction. The desktop app gives you a native interface to manage both of your keys with direct hardware wallet connections.
Desktop-Native Integration
The desktop app combines Unchained's full financial services suite with native hardware wallet connectivity. Manage vaults, trade bitcoin, monitor loans, and plan your estate — all from a single application with direct USB connections to your signing devices.
Offline-First Security
The desktop app processes all sensitive operations locally. Transaction construction, PSBT parsing, and address verification happen on your machine — never on a remote server. Your private keys never leave your hardware wallets, and the app communicates directly with your signing devices via USB.
Run health checks on your vault configuration, verify receive addresses against your hardware wallets, and review every transaction detail before signing — all from the security of your own desktop.
Security First
From day one, Unchained has maintained a perfect security record. The desktop app extends this track record with local-first processing and direct hardware wallet integration.
