Overview
Crypto security reimagined for the AI Agent era: Self-custodial automation, multi-chain, multi-factor, and the end of seed phrases. Your ultimate wallet.
Vultisig Project
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.
What is Vultisig?
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.
Key Features
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
How It Works
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
These are the most common configurations, but Vultisig supports a wide range of threshold setups for advanced users.
Why Vultisig?
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)
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.
