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:

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.
