Web3 Security Guide

What is Web3 Security?

Web3 Security is the practice of protecting your wallet, digital assets, and personal information while using blockchain applications.

Unlike traditional banking, blockchain transactions are usually irreversible. A single mistake—such as signing a malicious transaction or revealing your Secret Recovery Phrase—can permanently result in the loss of your assets.

Understanding Web3 security helps you confidently use wallets, DeFi, NFT marketplaces, bridges, and airdrops while reducing the risk of scams and attacks.
