Multi-Signature Wallets: Extra Security for Your Crypto

What is a Multi-Signature Wallet?

A multi-signature (multi-sig) wallet requires multiple approvals before a transaction is completed. Instead of one private key, it uses multiple keys held by different parties or devices.

How Does It Work?

• A wallet is set up with multiple private keys (e.g., 3 keys).
• A minimum number of keys (e.g., 2 out of 3) must approve a transaction before it is executed.
• Even if one key is compromised, the hacker cannot access funds without the other required keys.

Best Use Cases for Multi-Sig Wallets

✅ Joint Crypto Holdings – Ensures funds can’t be accessed by one person alone.
✅ Extra Security for Personal Use – Store keys on different devices to prevent single-point failure.
