Vultisig is an open-source vault with no seed phrase. It uses threshold signatures (MPC / TSS). Your key is split into shares. They sign together. One share cannot move funds.
One vault generates both ECDSA and EdDSA keys. You hold and sign Bitcoin, Ethereum, Cosmos, Solana, and 36+ other UTXO, EVM, BFT, and EdDSA chains. Named list: Wallet tab.
Signing uses DKLS23 from Silence Laboratories.
- No seed phrase. Vault shares replace 12/24-word seeds.
- MPC / TSS. Threshold signatures. No complete private key in normal operation.
- ECDSA and EdDSA. Both key types from one vault.
- 36+ chains from one vault.
- Platforms: iOS, Android, macOS, Windows, Linux, Chrome, Firefox.
- Open source on GitHub.
- No complete key. Shares sign together. One lost or stolen share cannot move funds.
- A normal signature on-chain. No published signer set, no extra contract. That is why it works on Bitcoin and in DeFi where on-chain multisig often does not.
- Devices you already own. Shares sit in the device Secure Enclave, behind biometrics.
- Open source and audited. Code on GitHub. Audit reports.
{% hint style="info" %} No registration. Vultisig does not keep your email. Fast Vaults use it once to send a backup file, then discard it. {% endhint %}
Think of the vault as a safe that needs a threshold of keys to open.
Fast Vault — Your device plus VultiServer (2-of-2). About a minute to set up. VultiServer signs with you and can never sign alone.
Secure Vault — Two or more devices you control:
- 2-of-2: both devices required. No fallback if one is gone.
- 2-of-3: the usual setup. You can lose one device and still sign.
- 3-of-4: three of four devices have to agree.
{% hint style="info" %} Those are the usual setups. Other thresholds are available if you need them. {% endhint %}
