How Multi-Sig Works
🔐 How Multi-Sig Works
More signers = more safety. And that’s built into every Vault.
Most wallets use a single private key to approve every transaction. Lose that key? You lose everything. Get hacked? You lose everything. Click the wrong link? You guessed it — gone.
Locked Money does things differently.
Every Vault is multi-signature by default — meaning it takes more than one approval to move your assets.
🧠 What Is Multi-Sig?
Multi-signature (multi-sig) is like a two-step approval process for crypto. Instead of just one wallet signing a transaction, your Vault can require multiple — like needing 2 out of 3 signers to approve.
This way:
If one device is lost, your assets are still safe
If a signer is compromised, they can’t act alone
You stay in control — and attackers stay locked out
🔑 How It Works in Locked Money
When creating your Vault, you can choose your signer setup:
Single signer (not recommended)
2-of-2 (default for many users)
Custom setups like 2-of-3 or 3-of-5 for advanced use cases
Each signer can be:
A wallet you control (MetaMask, Rabby, hardware wallet, etc.)
A trusted co-signer (e.g. a teammate, assistant, or cold wallet)
Your AI Co-Signer (Free Plan) — which acts like a smart guardian, blocking risky transactions
Need more signers later? You can add or remove them anytime — securely.
🔄 Example: How a Transaction Works
Let’s say your Vault requires 2-of-2 signers.
You create a transaction inside your Vault
You sign it with Wallet A
The transaction now waits for Wallet B
Once both signers approve, the transaction executes
🛡️ Why It’s Safer Than Seed Phrases
No seed phrase to lose or leak
No need to write anything down
No single key that unlocks everything
Signers can be spread across devices or locations
Signer wallets can be swapped if one is lost
🧩 Built for Flexibility
Whether you're a solo user or managing a company treasury:
Set simple 1-of-2 signers for quick security
Or go full 3-of-5 for serious asset protection
Add or remove signers anytime
Include the AI Co-Signer (Free Plan) for added protection
Your Vault, your rules — always in your control.
💬 Recommended for Maximum Protection
To get the full benefits of Locked Money's multi-sig security, we highly recommend:
Adding at least two wallets when creating your Vault (Otherwise, it behaves like a single-signer setup — and you lose the protection multi-sig provides.)
Using more than two signers if possible, to guard against loss of access. (Example: 2-of-3 setup — even if one wallet is lost, you stay safe.)
For the ultimate security experience, we recommend using our official partner: Tangem x Locked Money hardware wallets. These card-style cold wallets offer seedless, tamper-proof protection — perfect for acting as one of your Vault signers.
With proper multi-signature setup and trusted devices, your assets stay truly locked, protected, and under your full control.
