A practical security guide

Understand the risks.
Protect your crypto.

Cryptocurrency security depends on how digital assets, private keys, accounts, and devices are managed. Understanding common risks and following basic security practices can help reduce the likelihood of unauthorized access and accidental loss.

Essential practices

Everyday habits that matter

Basic precautions can help reduce exposure to common cryptocurrency threats.

Private Keys & Recovery Phrases

Private keys and recovery phrases provide control over cryptocurrency held in self-custody wallets.

  • Never share private keys or recovery phrases.
  • Store recovery phrases offline in a secure location.
  • Avoid saving sensitive wallet information in screenshots, email, or cloud storage.
  • Keep backups protected against theft, fire, and physical damage.

Account Security

Protect accounts associated with exchanges, wallets, and email services.

  • Use strong, unique passwords for every account.
  • Enable two-factor authentication whenever available.
  • Consider a hardware security key or authenticator app.
  • Review login activity and security notifications regularly.

Phishing & Online Scams

Fraudulent websites and messages may imitate legitimate cryptocurrency services.

  • Check website addresses before entering account information.
  • Avoid unexpected links and attachments.
  • Verify the identity of anyone requesting sensitive information.
  • Never share recovery phrases with customer support.

Wallet & Device Security

The security of a wallet also depends on the device used to access it.

  • Keep operating systems, browsers, and wallet software updated.
  • Download applications only from verified sources.
  • Protect devices with a strong passcode or password.
  • Avoid unknown browser extensions and software.

Transactions & Permissions

Blockchain transactions and smart contract interactions can have permanent consequences.

  • Verify the recipient address, network, and amount.
  • Understand transaction fees before confirming a transfer.
  • Review permissions requested by decentralized applications.
  • Do not sign transactions you do not understand.

Privacy & Public Networks

Untrusted connections and unnecessary disclosure can increase security risks.

  • Avoid accessing sensitive accounts over untrusted networks.
  • Do not disclose wallet balances or security details unnecessarily.
  • Remember that many blockchain transactions are publicly visible.
  • Be cautious when linking wallet addresses to personal information.

Know the risks

Common threats to understand

Recognizing the risks is an important part of making informed decisions.

Malware

Malicious software may monitor activity, steal information, or alter transaction details.

Unauthorized access

Accounts may be compromised through stolen passwords, exposed devices, or weak authentication.

Lost recovery information

Losing the recovery phrase for a self-custody wallet may mean permanent loss of access.

Third-party custody

Assets held with a service may be affected by account restrictions, security incidents, or service failure.

Malicious smart contracts

Some applications request permissions that can expose digital assets to loss.

Important information

Digital assets carry risk.

Cryptocurrency transactions are generally irreversible. Sending assets to an incorrect address or losing access credentials may result in permanent loss. No storage method or security measure eliminates every risk. Cryptocurrency values can fluctuate significantly, and theft, technical failures, human error, or third-party service disruptions may result in financial loss.
