Disclosure: CoinCodeCap may earn a commission if you sign up through links on this page. Risk warning: Multisig adds operational complexity. Lose two of three keys (in a 2-of-3) and your funds are permanently inaccessible. Test your recovery process with small amounts first. Treat each signer as separately as possible — same device or same backup location for multiple keys defeats the purpose. This guide covers wallet specifications and trade-offs, not legal or financial advice.

How I Picked These Wallets: I tested or have direct experience with each multisig wallet listed, ran end-to-end multisig setups (creating wallets, adding hardware signers, signing transactions), verified current product status (removing deprecated options like Armory and CoPay), and pulled current pricing from official sources through May 2026. The multisig landscape changed significantly between 2021 and 2026 — Nunchuk emerged as the no-KYC BTC standard, Safe (formerly Gnosis Safe) became the dominant smart-contract multisig with billions in TVL, Squads brought multisig to Solana, and several 2021-era picks (Armory, CoPay, Coinbase non-hosted multisig) shut down or became dormant.

Multisig wallets fundamentally change Bitcoin and crypto custody. Instead of a single seed phrase that controls everything (single point of failure), you split control across multiple keys held in separate locations or devices. Lose one key, you can still recover. Have one key compromised, the attacker can’t move funds alone. Set thresholds like 2-of-3 (two of three keys required), 3-of-5, or 4-of-7 based on your security model. The trade-off is operational complexity — but for meaningful holdings, multisig is the right answer.

This guide covers 12 multisig wallets across four categories: Bitcoin-focused multisig (Nunchuk, Sparrow, Specter, BlueWallet, Electrum), guided/managed services (Casa, Unchained Capital), smart-contract multisig (Safe, Squads, Argent), and institutional (BitGo). For broader context, see our companion guides on best hardware wallets, best smart contract wallets, and best anonymous Bitcoin wallets.

Multisig Wallet	Chain	Custody Model	Best For
Nunchuk	Bitcoin	Self-custody	Best no-KYC BTC multisig
Sparrow Wallet	Bitcoin	Self-custody	Desktop power users
Specter Desktop	Bitcoin	Self-custody	Hardware wallet coordinator
BlueWallet	Bitcoin	Self-custody	Mobile BTC multisig
Electrum	Bitcoin	Self-custody	Open-source veteran
Casa	BTC + ETH	Guided self-custody	Premium guided multisig
Unchained Capital	Bitcoin	Collaborative custody	HNW BTC holders, IRA
Safe (Gnosis Safe)	Ethereum/EVM	Self-custody (smart contract)	DAO treasuries, ETH multisig
Squads	Solana	Self-custody (smart contract)	Solana DAOs and teams
Argent	Ethereum/EVM	Smart wallet + social recovery	Mobile smart wallet users
BitGo	Multi-chain	Institutional custody	Institutions, exchanges
Coldcard + Sparrow	Bitcoin	Self-custody (HW)	Air-gapped BTC multisig
📌 My quick verdict — Nunchuk for BTC mobile multisig, Sparrow + Coldcard for power users, Casa for guided experience, Safe for Ethereum/EVM, Squads for Solana.

⚠️ Discontinued Multisig Wallets — Don’t Use These in 2026

Armory ❌ — Effectively dormant. Last meaningful update around 2019. The desktop client still launches but lags behind modern Bitcoin best practices (no native Segwit support in older builds, no Taproot, no hardware wallet integration on par with current alternatives). Migrate to Sparrow or Specter.
CoPay (BitPay) ❌ — Archived 2022. BitPay archived the CoPay GitHub repository and discontinued the wallet in favor of the BitPay app, which doesn’t offer the same self-custody multisig setup. If you have funds in legacy CoPay, migrate to BlueWallet or Sparrow.
Coinbase Wallet “non-hosted multisig” ❌ — Deprecated. The non-hosted Coinbase Vault multisig product was discontinued. Coinbase Wallet today is a single-sig self-custody wallet; for institutional multisig, Coinbase points users to Coinbase Custody/Prime. For consumer multisig, look elsewhere.
BitGo’s consumer self-custody multisig ⚠️ — BitGo today is primarily an institutional custody and prime brokerage platform. The consumer multisig wallet still exists but the focus and support have shifted heavily to institutional clients.
Single-sig “vault” features that aren’t true multisig ⚠️ — Some wallets advertise “vault” or “guardian” features that are actually time-locked withdrawals or social recovery, not true multisig. Read carefully before assuming a feature is what you need.

Bitcoin-Focused Multisig Wallets

1. Nunchuk — Best No-KYC Bitcoin Multisig

Nunchuk is the best no-KYC Bitcoin multisig in 2026. Free, open-source, mobile (iOS + Android) + desktop. Create 2-of-3, 3-of-5, or any custom M-of-N configuration with hardware wallet signers (Coldcard, Trezor, Ledger, Jade, Passport, BitBox02), TapSigners (NFC cards), or software keys — no signup, no email, no tracking. Tor support, Taproot support, coin control. Distinctive features include inheritance planning (with optional time-locked recovery), emergency access, and the “Honey Badger” plan for premium support and additional services.

Nunchuk’s strength is the combination of UX polish (mobile-first, polished iOS/Android apps) with no-KYC operation (rare in this category — most polished apps require email at minimum). For users wanting Casa-quality UX without the subscription fee or KYC, Nunchuk is the answer.

✅ No-KYC multisig — no signup, no email, no tracking
✅ M-of-N configurations with hardware wallets, TapSigners, software keys
✅ Mobile (iOS + Android) + desktop apps
✅ Tor support, Taproot, coin control
✅ Inheritance planning with optional time-locked recovery
✅ Free + paid Honey Badger tier for premium support
⚠️ Bitcoin-only — no altcoin multisig support
📌 Best for: Privacy-conscious BTC holders, mobile-first multisig users

2. Sparrow Wallet — Power-User Desktop Multisig

Sparrow Wallet is the desktop standard for serious Bitcoin multisig setups. Coordinate any M-of-N multisig with hardware wallets (Coldcard, Jade Plus, Trezor, Ledger, BitBox02, Foundation Passport) via PSBT (Partially Signed Bitcoin Transactions). Connect to your own Bitcoin Core node for maximum privacy. Full UTXO control. PayJoin (BIP78) support. Tor routing. Open-source. Free.

For multisig specifically, Sparrow’s strength is its uniquely complete view of every UTXO and signer status — you see exactly which keys have signed, which haven’t, and what the transaction will look like before broadcasting. Pair Sparrow with Coldcard for the strongest air-gapped multisig combo most users can practically run at home.

✅ Best UTXO + signer visibility of any multisig coordinator
✅ Pairs with all major hardware wallets via PSBT
✅ Connect to your own Bitcoin Core node
✅ PayJoin (BIP78) support, Tor routing, full coin control
✅ Open-source, no telemetry, free
⚠️ Desktop-only — no mobile version
⚠️ Power-user UX — steeper learning curve than Nunchuk
📌 Best for: Desktop BTC multisig with hardware wallets

Get Sparrow Wallet →

3. Specter Desktop — Pure Hardware-Wallet Coordinator

Specter Desktop is purpose-built for hardware-wallet-driven Bitcoin multisig. Designed by the team behind Specter DIY (a do-it-yourself open-source hardware wallet), Specter Desktop is the most opinionated multisig coordinator on this list — it assumes you’re using hardware wallets, you’re running your own Bitcoin Core node, and you want to do everything air-gapped where possible. Free, open-source, designed around PSBT workflows.

Where Sparrow is “great wallet that also does multisig well,” Specter is “purpose-built multisig coordinator.” Both are strong choices; Specter wins for users running serious self-hosted Bitcoin nodes and exclusively using hardware wallets. The trade-off: even more technical than Sparrow.

✅ Purpose-built for Bitcoin multisig with hardware wallets
✅ Designed around your own Bitcoin Core node
✅ Pairs with Coldcard, Trezor, Ledger, Jade, BitBox02, Specter DIY
✅ Free, open-source
⚠️ Most technical option — assumes self-hosted node + hardware wallets
⚠️ Desktop-only
📌 Best for: Bitcoin node operators running multisig with hardware wallets

Get Specter Desktop →

4. BlueWallet — Mobile Bitcoin Multisig

BlueWallet supports Bitcoin multisig directly on mobile (iOS + Android), making it one of the few non-Nunchuk options for BTC multisig on a phone. Create M-of-N vaults with hardware wallets via PSBT files (transferred via QR code or microSD), watch-only configurations, and import via Electrum-compatible descriptors. Free, open-source, no-KYC. Pair with Coldcard or Trezor for air-gapped signing on a mobile device.

BlueWallet’s multisig isn’t quite as polished as Nunchuk’s (Nunchuk is the dedicated specialist), but BlueWallet has the broader feature set — on-chain BTC, Lightning Network, custom Electrum servers, hardware wallet pairing, and multisig all in one app. For users who want one mobile app to handle BTC including multisig, BlueWallet is the right pick.

✅ Mobile multisig support (iOS + Android)
✅ Pairs with hardware wallets via PSBT (QR or microSD)
✅ Combines on-chain BTC + Lightning + multisig in one app
✅ Custom Electrum server support, watch-only
✅ Open-source, no-KYC, free
⚠️ Multisig UX less polished than Nunchuk’s specialist app
📌 Best for: Mobile users wanting one BTC app including multisig

Get BlueWallet →

5. Electrum — Open-Source Veteran with Multisig

Electrum has supported Bitcoin multisig since 2014 — the longest track record of any wallet on this list. Cross-platform (Windows, macOS, Linux, Android), open-source, lightweight (no full blockchain download required), supports M-of-N multisig with hardware wallets, custom Electrum server support, Tor routing, plugin ecosystem. The UI is utilitarian rather than polished, but Electrum’s longevity and stability make it a reasonable pick for multisig users who already use Electrum for single-sig.

✅ Multisig support since 2014 — longest track record
✅ Cross-platform: Windows, macOS, Linux, Android
✅ Hardware wallet integration, custom Electrum server
✅ Tor routing, plugin ecosystem, RBF
✅ Open-source, free
⚠️ Older UI compared to Nunchuk or Sparrow
⚠️ Multisig setup is more manual than dedicated multisig wallets
📌 Best for: Existing Electrum users adding multisig, Linux/Android multisig

Guided & Collaborative Custody Services

For users who want multisig protection but don’t want to manage all the keys themselves, “guided” and “collaborative” custody services hold one key on your behalf while you hold the others — combining self-custody with professional support.

6. Casa — Premium Guided Multisig

Casa offers guided multisig for Bitcoin and Ethereum with multiple membership tiers ($25/mo for the Standard plan, up to thousands per year for Diamond). The standard product is a 2-of-3 (Standard) or 3-of-5 (Diamond) multisig where Casa holds one or two keys (the “Casa key”), you hold the rest with hardware wallets, and Casa provides a polished mobile app, support, inheritance planning, and 24/7 emergency phone support. The trade-off: it’s a paid subscription, and you trust Casa for the held key (though Casa cannot move funds alone — they’re a single signer in a multisig).

For HNW Bitcoin holders who want self-custody with white-glove support, Casa is the standard. For users comfortable running multisig themselves, Nunchuk + hardware wallets gives you nearly everything Casa offers without the subscription fee.

✅ Guided multisig with white-glove support
✅ 2-of-3 (Standard) or 3-of-5 (Diamond) configurations
✅ Hardware wallet integration (Trezor, Ledger, Coldcard, etc.)
✅ Inheritance planning + 24/7 emergency phone support
✅ Bitcoin and Ethereum support
⚠️ Paid subscription ($25/mo to thousands per year)
⚠️ Casa holds 1-2 keys (though they can’t move funds alone)
📌 Best for: HNW BTC/ETH holders wanting white-glove multisig

Get Casa →

7. Unchained Capital — Collaborative BTC Custody

Unchained Capital offers collaborative custody specifically for Bitcoin — typically 2-of-3 multisig where you hold two keys and Unchained holds one. Unique features include Bitcoin-backed loans (borrow USD against your multisig BTC without selling), Bitcoin IRA products (self-custody Bitcoin in a tax-advantaged retirement account — rare), and inheritance planning. US-focused, regulated. Different positioning from Casa: more financial-services-oriented, with loans and IRA wrappers as core offerings beyond just custody.

✅ Bitcoin-only collaborative custody (2-of-3 typical)
✅ Bitcoin-backed loans against your multisig
✅ Bitcoin IRA products (self-custody retirement accounts)
✅ Inheritance planning, regulated US entity
⚠️ Annual fees apply
⚠️ US-focused — may not be available globally
⚠️ Bitcoin-only
📌 Best for: HNW BTC holders wanting loans, IRA, or US regulated framework

Smart-Contract Multisig Wallets

Smart-contract multisig works fundamentally differently from Bitcoin multisig. Instead of multiple signatures combining to satisfy a Bitcoin script, a smart contract on Ethereum (or another EVM chain) enforces the M-of-N rule on-chain. The contract address holds the funds; the contract code requires M signatures from N approved signer addresses to execute any transaction.

8. Safe (formerly Gnosis Safe) — The Ethereum Multisig Standard

Safe is the dominant smart-contract multisig wallet on Ethereum and EVM chains, with billions of dollars in TVL across DAOs, treasuries, and individual users. Free, open-source, web + mobile apps, supports Ethereum mainnet plus 10+ L2s and EVM chains (Arbitrum, Optimism, Base, Polygon, Gnosis, Avalanche, more). Configure any M-of-N with EOA addresses (MetaMask, hardware wallets, etc.) as signers. Critical features include transaction queuing (proposers add txs, signers approve over time), spending limits, modules for advanced workflows, and integration with most major DeFi protocols.

If you’re holding meaningful ETH or running an EVM treasury (DAO, project, multi-person fund), Safe is the default answer. The trade-off vs Bitcoin multisig: smart contract risk (the contract has been heavily audited, but smart contract bugs are non-zero), gas fees (every transaction confirms on-chain), and Ethereum-only. See our best Ethereum wallets guide for context on how Safe fits into the broader ETH wallet landscape.

✅ Most-used smart-contract multisig — billions in TVL
✅ Ethereum mainnet + 10+ EVM chains supported
✅ Web + mobile apps, free, open-source
✅ Hardware wallet support (Ledger, Trezor)
✅ Transaction queuing, spending limits, modules
✅ Standard for DAO treasuries, fund custody, team multisig
⚠️ Smart contract risk (mitigated by extensive audits)
⚠️ Gas fees per transaction
📌 Best for: Ethereum/EVM multisig, DAO treasuries, team funds

Get Safe →

9. Squads — The Solana Multisig Standard

Squads is the Safe-equivalent for Solana — the dominant smart-contract multisig on Solana with significant TVL across DAOs, projects, and individual users. Free, open-source, web app. Configure any M-of-N with Solana wallet addresses (Phantom, Solflare, Backpack, Ledger, etc.) as signers. Strong fit for Solana DAOs, multi-founder projects, and anyone needing collaborative custody of meaningful SOL or SPL tokens.

Solana’s low transaction fees (typically <$0.01) make Squads particularly practical — the gas-cost concern that exists with Safe on Ethereum mainnet doesn't apply on Solana.

✅ Dominant Solana multisig — significant TVL
✅ Free, open-source, web app
✅ Compatible with Phantom, Solflare, Backpack, Ledger Solana
✅ Standard for Solana DAOs, projects, team treasuries
✅ Solana’s low fees make every signing affordable
⚠️ Solana-only — no other chain support
⚠️ Smart contract risk (mitigated by audits)
📌 Best for: Solana DAOs, projects, multi-founder teams

Get Squads →

10. Argent — Smart Wallet with Social Recovery

Argent isn’t traditional multisig but solves a similar problem differently. It’s a smart-contract wallet on Ethereum (mainnet + Starknet) with built-in social recovery — designate “guardians” (other people’s wallet addresses or hardware wallets) who can collectively recover your wallet if you lose access. Plus daily spending limits (block large unauthorized withdrawals), trusted contacts (skip approval delays for whitelisted addresses), and seedless onboarding (no seed phrase to lose).

Argent’s social recovery is conceptually adjacent to multisig — you’re using multiple parties to authorize sensitive actions — but it’s optimized for individual users rather than team/DAO treasuries. Better alternative to traditional multisig if you’re a single user wanting protection against losing your seed phrase, but it doesn’t replace Safe for team/DAO use cases.

✅ Smart-contract wallet with social recovery (multisig-adjacent)
✅ Designate guardians who can collectively recover the wallet
✅ Daily spending limits, trusted contacts, no seed phrase
✅ Mobile app on iOS + Android
✅ Ethereum mainnet + Starknet support
⚠️ Not a true M-of-N multisig — different security model
⚠️ Mostly suited for individual users, not team treasuries
📌 Best for: Solo users wanting seed-phrase-loss protection on Ethereum

Get Argent →

Institutional Multisig

11. BitGo — Institutional Multi-Chain Custody

BitGo is a regulated institutional digital asset custodian, primarily serving exchanges, hedge funds, asset managers, and high-net-worth clients. The product is a 2-of-3 or 3-of-5 multisig (depending on configuration) where BitGo holds keys, the client holds keys, and a backup key is stored offline. BitGo’s policies enforce withdrawal whitelists, spending limits, role-based permissions, and compliance reporting. Multi-chain — Bitcoin, Ethereum, and dozens of other supported assets. Insurance-backed (subject to terms).

For institutions: BitGo is the most-used qualified custodian using multisig. For consumer users: BitGo’s consumer-facing self-custody multisig wallet still exists but the focus and active product development has shifted heavily toward institutional clients. Look at the other 10 wallets in this guide for consumer multisig.

✅ Regulated qualified custodian using multisig + cold storage
✅ Multi-chain — BTC, ETH, dozens of others
✅ Withdrawal whitelists, spending limits, role-based permissions
✅ Compliance reporting, insurance-backed
✅ Used by major exchanges, funds, institutions
⚠️ Institutional pricing — not for retail users
⚠️ Consumer multisig product is no longer the focus
📌 Best for: Institutions, exchanges, regulated funds

12. Coldcard + Sparrow — DIY Air-Gapped BTC Multisig Stack

Not a single product, but the most-recommended DIY combo for serious Bitcoin multisig: 3 Coldcard hardware wallets (~$157 each, BTC-only, air-gapped via microSD) + Sparrow Wallet (free desktop coordinator) + 3 SeedPlate steel backups (~$50 each). Total cost: roughly $621 for hardware, plus your own time. The result: a 2-of-3 air-gapped Bitcoin multisig with the strongest practical security model most users can run at home, no monthly fees, no third-party trust, full self-custody, completely open-source firmware on the signers.

This is the setup serious Bitcoiners build instead of paying Casa or Unchained for guided multisig — when you’ve absorbed the operational discipline and want to run everything yourself.

✅ Strongest practical home-multisig security model
✅ Air-gapped via microSD — no USB/wireless on signers
✅ Open-source firmware on all components (Coldcard, Sparrow)
✅ One-time hardware cost, no monthly fees
✅ Full self-custody, no third-party trust
⚠️ ~$621 hardware investment for a 2-of-3 setup
⚠️ Power-user setup — requires technical comfort
⚠️ Bitcoin-only
📌 Best for: Serious BTC HODLers wanting maximum DIY multisig security

What is a Multisig Wallet? (And Why Use One)

A standard crypto wallet uses one private key to sign transactions. One key = total control = single point of failure. Lose the key (or have it stolen), and your funds are gone permanently. A multisig wallet requires multiple signatures from a predefined set of keys to authorize transactions. The standard notation is M-of-N — for example, 2-of-3 means three keys exist, and any two are sufficient to spend.

The distribution rule is what makes multisig powerful: store each key in a different location, on a different device, with a different recovery method. A 2-of-3 setup might have one key on a Coldcard at home, one on a Trezor at a parent’s house, and one on a BitBox02 in a safe deposit box. An attacker would need to physically compromise two locations simultaneously to steal funds. Lose any one key, and the remaining two still sign transactions.

Common M-of-N Configurations

1-of-2 — Joint account model. Two friends each have a key; either can spend independently. Convenient but provides no security improvement over single-sig.
2-of-2 — Both keys required. Strong security but no recovery — lose either key and funds are stuck. Use only if you have rock-solid backups for both.
2-of-3 — The most common practical setup. Three keys; any two sign. Lose one key and you can still recover. Have one key compromised and the attacker can’t spend alone. Strong sweet spot for most personal multisig.
3-of-5 — More distributed; suits larger amounts or family/team setups. Five keys across five locations or holders; any three sign. Higher operational complexity.
4-of-7 or higher — Institutional or large DAO setups. Operational overhead is significant; only use if the security benefit justifies it.

When You Should Use Multisig

Holdings large enough that single-sig loss is catastrophic — meaningful Bitcoin or crypto positions where losing access destroys real wealth.
Inheritance planning — distribute keys across trusted parties so heirs can recover funds without depending on a single point of failure.
Team or DAO treasuries — multiple stakeholders need to authorize spending; no single person can drain the treasury.
Joint custody between partners — couples or business partners managing shared funds without either party having unilateral control.
Geographic distribution — keys in different countries protect against jurisdiction-specific risks (theft, legal seizure, natural disaster).

My Recommended 2026 Setup

“I want Bitcoin multisig on mobile, no KYC, free.” → Nunchuk with hardware wallet signers (Coldcard, Jade Plus, Trezor Safe 5).
“I want maximum control, desktop, willing to learn.” → Sparrow Wallet + 3 Coldcards for a 2-of-3 air-gapped setup. ~$621 in hardware, free software.
“I want guided support and don’t mind paying.” → Casa Standard tier ($25/mo) for Bitcoin + Ethereum, or Diamond (much more) for white-glove HNW service.
“I want Bitcoin multisig + loans/IRA.” → Unchained Capital for the financial-services side beyond just custody.
“I’m setting up a DAO or team treasury on Ethereum.” → Safe (formerly Gnosis Safe). The standard answer.
“I’m setting up a DAO or team treasury on Solana.” → Squads. The Solana equivalent of Safe.
“I’m a solo Ethereum user who wants seed-phrase-loss protection.” → Argent. Smart-contract wallet with social recovery.
“I’m an institution, exchange, or regulated fund.” → BitGo. Qualified custodian with compliance + insurance.

For most personal Bitcoin multisig: Nunchuk + 3 hardware wallets (mix of Coldcard / Jade / Trezor / BitBox02 / Passport for diversity) + 3 steel seed backups in 3 separate locations. Total ongoing cost: zero (after one-time hardware purchase). For Ethereum/EVM multisig: Safe. For Solana: Squads.

Frequently Asked Questions

What’s the best multisig wallet for Bitcoin?

Nunchuk for mobile-first no-KYC use; Sparrow Wallet + Coldcard for desktop power users; Casa for guided/managed multisig with white-glove support; Unchained Capital if you also want loans or IRA wrappers. Most serious BTC multisig users in 2026 build a self-managed Sparrow + Coldcard 2-of-3 setup or use Nunchuk on mobile with diverse hardware wallet signers.

What’s the best multisig for Ethereum?

Safe (formerly Gnosis Safe) is the dominant Ethereum and EVM multisig in 2026, with billions in TVL. Standard for DAO treasuries, project funds, and personal multi-key Ethereum setups. Free, open-source, supports Ethereum mainnet plus Arbitrum, Optimism, Base, Polygon, Gnosis, Avalanche, and other major EVM chains. For solo users wanting seed-phrase-loss protection without traditional multisig, Argent’s social recovery is the alternative.

What’s the difference between Bitcoin multisig and Ethereum multisig?

Bitcoin multisig is enforced by Bitcoin’s scripting language at the protocol level. M-of-N keys sign a transaction, and the resulting transaction is broadcast to the Bitcoin network like any other. Lower fees, no smart contract risk, but limited flexibility. Ethereum/EVM multisig is enforced by a smart contract — the contract holds funds, the contract code requires M-of-N signatures from approved signer addresses to execute. More flexible (can encode custom rules, spending limits, time locks), but adds smart contract risk and gas fees per transaction. Both are mature and widely used.

What happened to Armory and CoPay?

Both projects became dormant or were officially deprecated. Armory was a popular cold-storage Bitcoin wallet from 2011–2018 but development effectively stopped around 2019. The desktop client still launches but lacks modern Bitcoin features (Segwit, Taproot, current hardware wallet integrations). CoPay was BitPay’s open-source HD multisig wallet; BitPay archived the GitHub repository in 2022 and migrated users to the BitPay app, which doesn’t offer the same self-custody multisig experience. Migrate from either to Sparrow, Nunchuk, BlueWallet, or Specter.

Should I use 2-of-3 or 3-of-5 multisig?

2-of-3 is the most common practical setup for personal Bitcoin multisig — strong recovery (lose any one key, still recover), strong security (compromise of any single key doesn’t drain funds), manageable operational complexity. 3-of-5 distributes risk across more locations or holders, which suits larger amounts, family setups, or institutional/DAO treasuries — but the operational overhead (managing 5 keys vs 3) is significantly higher. Start with 2-of-3 unless you specifically need the additional distribution.

Is Casa worth the subscription fee vs DIY Nunchuk?

Depends on operational comfort. Casa charges $25/mo (Standard) to thousands/year (Diamond) for guided multisig with 24/7 phone support, white-glove inheritance planning, and the convenience of having Casa hold one key. DIY Nunchuk is free but requires you to manage all keys yourself. For HNW Bitcoin holders ($1M+ in BTC) where the cost is rounding error and the support is genuinely useful (especially for inheritance planning involving non-technical heirs), Casa is reasonable. For users comfortable with self-managed multisig, Nunchuk + hardware wallets gives you nearly everything Casa provides without the subscription.

Can I use multisig for inheritance planning?

Yes — multisig is the standard self-custody approach to crypto inheritance. Common patterns: distribute keys across trusted family members or executors so a 2-of-3 (or 3-of-5) can be reconstructed if you become incapacitated. Casa, Unchained Capital, and Nunchuk all offer specific inheritance products built on multisig. The key consideration: heirs need both the keys AND the knowledge of how to use them. A working inheritance plan includes documented recovery instructions, ideally tested while you’re alive.

What’s the difference between multisig and MPC?

Multisig (Bitcoin script or smart contract) requires multiple discrete signatures that all appear on-chain. MPC (Multi-Party Computation) computes a single signature from key shares held by multiple parties, with the on-chain result looking identical to a single-sig transaction. Privacy benefit: MPC transactions don’t reveal that multiple parties signed. Trade-off: MPC implementations are newer and less standardized than traditional multisig. Most consumer wallets in 2026 still use traditional multisig; MPC is more common in institutional custody (Fireblocks, Copper, etc.).

Multisig is the right answer for any meaningful crypto holding in 2026. The specific wallet depends on what you hold and how you want to manage it: Nunchuk for no-KYC Bitcoin mobile, Sparrow + Coldcard for serious DIY BTC, Casa for guided premium support, Unchained Capital for BTC + loans/IRA, Safe for Ethereum/EVM, Squads for Solana, Argent for solo ETH users, BitGo for institutions.

The discontinued options matter too: Armory is dormant, CoPay was archived in 2022, and Coinbase’s non-hosted multisig is gone. The 2021-era playbook of “Armory + Coinbase + CoPay” no longer applies. The current playbook is mature, well-supported, and broadly accessible — pick from the 12 active wallets in this guide based on your specific use case.

Reviewed by Gaurav Agarwal, founder of CoinCodeCap. Gaurav has covered Bitcoin multisig setups, Safe (Gnosis) on Ethereum, hardware wallet pairing, and self-custody best practices since 2018, with hands-on testing of every wallet in this guide. Wallet status (Armory, CoPay deprecation, Casa pricing, Safe TVL) reflects direct research and verification through May 2026.

⚡ Bottom Line: 2026 best multisig wallets: Nunchuk (no-KYC BTC mobile), Sparrow Wallet (BTC desktop power user), Specter Desktop (BTC hardware-coordinator), BlueWallet (BTC mobile), Electrum (BTC veteran), Casa (guided BTC+ETH, $25/mo+), Unchained Capital (BTC + loans/IRA), Safe/formerly Gnosis Safe (Ethereum/EVM standard), Squads (Solana standard), Argent (smart wallet w/ social recovery), BitGo (institutional), and the DIY combo Coldcard + Sparrow (~$621 hardware). Avoid Armory (dormant), CoPay (archived 2022), and old Coinbase Wallet multisig (deprecated). Most users: 2-of-3 is the practical sweet spot. Distribute keys across separate locations and devices.
