🔐 What is a Multi-Signature Wallet? Enhancing Crypto Security

🏗️ Introduction

A multi-signature (multi-sig) wallet requires multiple private keys to approve transactions, adding extra security to crypto holdings.

🔹 Prevents single-point failure – No single user controls the funds.
🔹 Ideal for businesses & DAOs – Shared access improves security.
🔹 Protects against hacks & fraud – Reduces risk of unauthorized withdrawals.

Multi-sig wallets add an extra layer of protection to crypto transactions.

🔄 How Does a Multi-Signature Wallet Work?

Multi-sig wallets require multiple private keys to authorize a transaction, instead of relying on a single private key.

🔹 Common Multi-Sig Setups

✅ 2-of-3 – Requires 2 out of 3 key holders to approve transactions.
✅ 3-of-5 – Requires 3 out of 5 signatures to execute a transfer.
✅ Custom Configurations – Organizations can define their own security rules.

💡 Example:

• A company treasury uses a 3-of-5 multi-sig wallet, meaning at least 3 executives must approve transactions.

Multi-sig wallets ensure no single entity can move funds alone.
