Vultisig is an open-source cryptocurrency vault that takes a novel approach: seedless, multi-factor, multi-chain security based on MPC (Multi-Party Computation) technology.
Available on iOS, Android, macOS, Windows, Linux, and as a browser extension—Vultisig delivers multi-sig level security without the traditional multi-sig complexity.
Vultisig is a multi-chain, multi-factor, multi-platform Threshold Signature Scheme (TSS) vault. No specialized hardware required.
Supporting UTXO, EVM, BFT, and EdDSA chains (Bitcoin, Ethereum, Cosmos, Solana, and 30+ more), Vultisig generates both ECDSA and EdDSA signature keys for every vault. Hold and sign for BTC, ETH, SOL, and more from a single vault setup.
Powered by DKLS23, a state-of-the-art TSS protocol developed by Silence Laboratories.
Built by the founders of THORChain—creators of the largest and longest-running multi-chain DEX powered by Threshold Signature Schemes.
- No seed phrases: Vault shares replace vulnerable 12/24 word seeds
- Multi-chain: 30+ blockchains from one vault (Bitcoin, Ethereum, Solana, Cosmos, and more)
- Multi-factor: Multiple devices required to sign transactions
- Multi-platform: iOS, Android, macOS, Windows, Linux, Browser Extension
- Open source: Fully auditable code on GitHub
Vultisig works like a traditional multisig wallet but with flexible setup options and modern convenience.
Fast Vault — Single device + Vultisig server. Quick setup, instant signing.
Secure Vault — Multiple devices you control:
- 2-of-2: Fastest setup, no fallback
- 2-of-3: Recommended, with fallback device
- 3-of-4: Maximum security, with fallback device
{% hint style="info" %} These are the most common configurations, but Vultisig supports a wide range of threshold setups for advanced users. {% endhint %}
Better security model:
- Vault shares don't store funds—no funds at risk if you lose a share
- No on-chain registration of signing keys
- Compatible with all chains and fully DeFi compatible (multi-sigs often aren't)
Uses devices you already own:
- Phones, tablets, laptops with familiar interfaces
- Secure Enclaves protect vault shares
- Biometric authentication built-in
- Doesn't look like a hardware wallet (better operational security)
Open source and audited:
- Fully transparent codebase on GitHub
- Security audits completed (view reports)
{% hint style="info" %} No registration required. Vultisig never permanently stores your email or personal info. Fast Vaults briefly require email to send backup files—used once and not retained. {% endhint %}
