Best crypto security practices 2026: From wallets to approvals
Security in crypto and DeFi is becoming increasingly important in 2026 as phishing attacks, exploits, and social engineering grow more sophisticated.
Here are several best practices that should be applied:
Hardware wallet vs software wallet
Use a hardware wallet (such as Ledger or Trezor) to store large or long‑term assets. A hardware wallet keeps the private key offline, making it far safer from online attacks.
In contrast, software wallets (Phantom, MetaMask, Rabby) are more suitable for daily transactions and small amounts because they are more convenient, though the risk is higher as they are always connected to the internet.
Revoke token approvals regularly
Many scams occur through unrestricted token approvals. Regularly check and revoke unnecessary approvals using tools. This habit can prevent large losses if a protocol is hacked or becomes dangerous.
Use a hardware security key
For two‑factor authentication (2FA), avoid SMS and use a hardware security key like YubiKey. It is far more secure against phishing and SIM swapping compared to regular authenticator apps. Enable it on exchanges and other important services.
Properly back up the seed phrase
Write the seed phrase on a water‑ and fire‑proof physical medium (such as a metal plate). Never store it digitally, as a screenshot, or in the cloud. Keep it in a safe, separate location.
If possible, perform periodic recovery tests to ensure your backup truly works.
Crypto security is not about a single tool, but a combination of consistent habits.
