Specter Desktop

Specter Desktop is the coordinator for Bitcoiners who refuse to trust anyone else's server: it pairs your hardware wallets with your own full node to run single-sig or multisig vaults, so your balance, your addresses, and your transaction history never leak to a third party.

Background Open-source and community-developed, Specter Desktop connects directly to your Bitcoin Core node and speaks fluent hardware-wallet — Coldcard, Trezor, Ledger, BitBox, SeedSigner, and more. It is built specifically for multisig and air-gapped workflows, an audience underserved by consumer wallets.

What you trust You trust your own node and open-source code, not a company's backend. Because Specter queries your Bitcoin Core directly, there is no third-party server learning which addresses are yours — a privacy property most wallets quietly surrender. PSBT-based signing keeps keys on the hardware devices.

Operational specs Desktop app driving multisig (m-of-n) across mixed hardware vendors, with PSBT export/import for air-gapped signing (QR or microSD). Full Bitcoin Core integration for trustless balance/history. Supports Tor, watch-only wallets, and coin control. A power tool for self-custody rather than a one-tap mobile wallet.

Philosophy Specter's stance is that real self-custody means real self-verification: run your own node, own your privacy, and don't outsource the validation of your own money. It treats multisig — the strongest defense against single-point key loss or theft — as a first-class, approachable workflow.

Grade rationale Grade A. Best-in-class node-backed multisig coordination, vendor-agnostic hardware support, and genuine privacy from running against your own Core. The full-node requirement and learning curve keep it from being a beginner pick, but for its intended advanced-custody role it excels.

Useful when You run (or will run) a Bitcoin full node and want trustless, private balance/history; you're building multisig across multiple hardware wallets; you want air-gapped PSBT signing; you reject third-party-server wallets.

Caveats Bitcoin-only, and it expects you to run Bitcoin Core — a real setup and maintenance commitment. The multisig and node workflow has a learning curve; misconfigured backups can lock you out. It coordinates signing, it doesn't hold keys — pair it with hardware wallets you back up carefully.
