Best Crypto Wallets for Multi-Sig Security in 2024

Imagine a safe that needs two keys to open — one held by you, another by your partner. Now scale that to three, four, or even fifteen keys, where any M-of-N combination can authorize a transaction. That's the promise of multi-signature (multisig) wallets: they eliminate the single point of failure that has drained billions from single-key wallets through phishing, malware, and physical theft.1

For high-net-worth individuals, family offices, and corporate treasuries, multisig isn't optional — it's the baseline. The question is which setup to trust. We evaluated the leading options across three categories: Bitcoin-centric software, multi-chain smart-contract wallets, and hardware-backed solutions. Here are the things actually worth buying.

The Best Multisig Crypto Wallets

1. Electrum — Best Bitcoin Multisig Coordinator

Electrum has been the gold standard for Bitcoin multisig since long before the term "multisig" entered mainstream crypto vocabulary. It supports up to 15 cosigners in any M-of-N configuration, integrates with nearly every major hardware wallet, and has been battle-tested for over a decade.1

What sets Electrum apart is its flexibility. You can run it as a hot wallet, pair it with a hardware signer like Coldcard or Trezor, or use it as a watch-only coordinator that never touches private keys. The codebase is fully open source, and the wallet's lightweight SPV model means you don't need to download the full Bitcoin blockchain.

2. Coldcard — Best Air-Gapped Hardware Signer

Coldcard is the hardware wallet that security-conscious Bitcoiners trust for their most critical keys. It's designed specifically for multisig setups, with native support for PSBTs (Partially Signed Bitcoin Transactions) that let you sign transactions on a device that never touches the internet.1

The Mk4 model adds a secure element and improved tamper resistance, but the real value is in the workflow: you generate keys offline, sign via microSD or NFC, and broadcast through a coordinator like Electrum or Sparrow. Coldcard is also fully open source, with reproducible builds that let you verify the firmware matches the published source code.

3. Trezor Safe 3 — Best Hardware Wallet for Multi-Chain Multisig

Trezor's Safe 3 is the most accessible entry point for multisig that spans multiple blockchains. While Electrum and Coldcard are Bitcoin-focused, Trezor integrates with smart-contract multisig platforms like Safe (formerly Gnosis Safe) on Ethereum and other EVM chains.1

The Safe 3 uses a secure element chip and supports Shamir Backup (a form of key sharding) out of the box. It's also one of the few hardware wallets that works seamlessly with collaborative custody providers like Casa and Unchained Capital, which we'll discuss below.2

4. Keystone Pro — Best Modern Air-Gapped Alternative

Keystone has emerged as a serious contender in the hardware wallet space, particularly for multisig users who want an air-gapped device with a modern UX. It uses QR-code-based signing — no USB, no Bluetooth, no microSD — which makes it compatible with mobile-first coordinators like Nunchuk.2

The large touchscreen display and camera make transaction verification genuinely pleasant, and the device supports both Bitcoin-only and multi-chain firmware. For users building a multisig setup with Nunchuk or Casa, Keystone is the hardware signer that balances security with usability.

Software-Only vs. Hardware-Integrated Multisig

The biggest decision you'll make is whether to run a software-only multisig (all keys are hot) or integrate hardware signers. Software-only is faster and cheaper, but each key lives on a device that could be compromised. Hardware-integrated multisig — where at least one key lives on a Coldcard, Trezor, or Keystone — adds physical security that's hard to beat.1

For most users holding significant value, we recommend a 2-of-3 setup with two hardware signers and one software key (or a third hardware key stored in a separate location). This gives you redundancy without sacrificing security.

DIY vs. Collaborative Custody

If you're comfortable managing keys and coordinating signatures yourself, Electrum + Coldcard or Sparrow + Keystone is the way to go. But if you want a managed experience, collaborative custody providers like Casa and Unchained Capital handle the coordination layer for you.2

Casa offers tiered plans (Gold: 2-of-3, Platinum: 3-of-5) with hardware wallet integration and inheritance planning. Unchained Capital provides a similar model with a focus on Bitcoin-only multisig and a flat monthly fee. Both are excellent options for non-technical users who want institutional-grade security without the DIY complexity.2

Why These Picks

Every wallet we selected is open source (or has reproducible builds), has undergone independent security audits, and integrates with the broader multisig ecosystem. We prioritized wallets that have been battle-tested over years — not flashy newcomers with unproven code. Whether you're securing a personal retirement fund or a corporate treasury, these are the wallets that let you sleep at night knowing no single key, device, or mistake can drain your funds.
