MultisigMultisig
across chains.
Secure your assets across several of your own devices. One vault covers Bitcoin, Ethereum, Solana and most other networks in the app, with their tokens. Custom setups, each device backed up on its own.
- 2-of-3
- 3-of-4
- Individual backups
No single key. No single mistake.
A normal wallet has one secret. Lose it or leak it and the funds are gone. A vault splits control across your devices, so several of them have to agree before anything moves.
- Use multiple devices to sign
- Each device individually backed up
- Custom setups: 2-of-3, 3-of-4 and more
One vault. Across chains.
Most multisigs are tied to one network. A THORWallet vault covers Bitcoin, Ethereum, Solana and most other networks in the app, with their tokens, under the same set of devices.
- One set of devices for every chain
- Monero, NEAR and Osmosis stay in a seed wallet
Secure, and still usable.
A vault is not cold storage you never touch. Send, receive and swap across chains from the vault, with the same shared approval on every transaction.
| Send, receive, swap | Yes | Every transaction needs the number of devices you chose. |
|---|---|---|
| WalletConnect | Yes | Your devices sign each request together. |
| Earn | SUI staking | Aave, Blend and RUJI need a seed wallet in the mobile app. |
| Card, perpetuals, stocks | Seed wallet | In the mobile app these are not available with a vault selected. |
| Threshold | Two thirds of the devices | At least: 2 of 2, 2 of 3 or 3 of 4. |
| Backup | One file per device | Protected with a password you set. Keep the files of different devices in different places. |
| Zcash | Transparent addresses | Shielded Zcash is held in a seed wallet. |
| Cost | Free | You pay network fees when you send. |

Three devices. A few minutes.
Start a vault
Open THORWallet on your first device, choose to create a vault, and pick how many devices should hold it.
Pair your devices
Join with your other devices. Together they create the vault, and each one ends up with its own share.
Back up each one
Save each device's backup in a different place. From now on, sending needs the number of devices you chose.
Vaults, answered.
What is a multisig vault?
A wallet that needs more than one device to approve a transaction. In a 2-of-3 vault, any two of your three devices sign together. One device alone cannot move funds.
How is that safer than a seed phrase?
A seed phrase is one secret: whoever has it has everything. A vault has no single secret. Losing one device, or having one device compromised, is not enough to lose your funds.
Which chains and tokens work in a vault?
A vault works across chains: Bitcoin, Ethereum, Solana and most other networks in the app, with their tokens, under one set of devices.
What can I not do from a vault?
In the mobile app, the card, perpetuals and tokenized stocks need a seed wallet, and Monero, NEAR and Osmosis are held in a seed wallet only. You can keep a seed wallet and a vault side by side.
What happens if I lose a device?
As long as you still have enough devices to reach the threshold, you can keep signing. Each device has its own backup, so you can restore a lost one. Keep the backups in separate places.
Do I still need a seed phrase?
A vault does not use a seed phrase. Each device keeps its own share and its own backup file instead.
Does THORWallet hold one of the shares?
No. The shares live on your own devices. THORWallet has no share and cannot sign for you.
The fine print
- A vault protects against the loss or compromise of a single device. It does not protect you if you lose more devices and backups than your threshold allows. Keep backups in separate places.
- THORWallet is self-custody software. We hold no shares or keys and cannot recover funds for you.
