A Beginner's Guide to Crypto Security
Speak to a Support Specialist: 1-888-400-6142Welcome to the Crypto Help Center. We provide guidance on securing your digital assets and troubleshooting common issues. This guide provides information only and is not official support for any specific platform.
Understanding Wallet Security
The most important part of crypto is security. Your "wallet" is not like a physical wallet. It's a set of digital keys—a **public key** (like your email address, safe to share) and a **private key** (like your password, never share it).
- Hot Wallets: Software wallets connected to the internet (e.g., mobile apps). Convenient but less secure.
- Cold Wallets: Hardware devices (like a USB drive) kept offline. The most secure way to store assets.
What is 2FA (Two-Factor Authentication)?
2FA is a critical security layer. Even if a hacker steals your password, they cannot log in without a second code from a device you own. We strongly recommend using an **Authenticator App** (like Google Authenticator or Authy) instead of SMS (text message) 2FA, as SMS can be vulnerable to "SIM-swapping."
Common Transaction Issues
Sometimes, transactions can get "stuck" or show as "pending." This is often due to high network traffic or low "gas fees" (the fee paid to the network). If you need help diagnosing a stuck transaction or understanding an error, our specialists can guide you through the process of checking a block explorer.
