# Best Practices: Securing Digital Assets (Crypto, NFTs, and Tokens)
## Overview
These practices address the unique security risks associated with digital assets (cryptocurrencies, tokens, NFTs), which are decentralized and overwhelmingly secured by private keys and seed phrases residing in digital wallets. The goal is to mitigate risks from hacking, phishing, malware, and human error.
## Key Recommendations
### Immediate Actions
1. **Secure Seed Phrases Offline:** Immediately transfer all 12-24 word seed phrases offline. *Never* store them on a computer, in the cloud, or digitally accessible via an internet-connected device.
2. **Enable Strong 2FA on Exchanges/Accounts:** Activate Two-Factor Authentication (2FA) on all cryptocurrency exchange and digital asset platform accounts.
3. **Avoid SMS-Based 2FA:** If currently using SMS 2FA, immediately switch to an authenticator app (like Google Authenticator or Authy) due to the vulnerability of SMS to SIM-swapping attacks.
4. **Verify All Wallet Addresses:** Before executing any cryptocurrency transaction, meticulously double-check the recipient wallet address. Remember: transactions are irreversible.
### Short-term Improvements (1-3 months)
1. **Migrate to Non-Custodial Wallets for Holdings:** For high-value or long-term holdings, transition assets from custodial wallets (third-party exchanges) to personal, non-custodial wallets where you control the private keys.
2. **Implement Strong Password Management:** Create and enforce strong, unique passwords for every crypto-related account (wallets, exchanges) and manage them using a reputable password manager. Never reuse passwords.
3. **Install Protection Against Malware:** Ensure all devices used to manage digital assets (wallets, browser sessions) have up-to-date antivirus/anti-malware software to prevent credential and key theft.
### Long-term Strategy (3+ months)
1. **Establish Secure Seed Phrase Redundancy:** Create redundant, highly secure offline backups of your seed phrases (e.g., metal storage, separate geographically distributed secret locations).
2. **Maintain Threat Awareness:** Establish a routine for reviewing current phishing tactics, social engineering schemes, and new software vulnerabilities specific to the digital asset ecosystem.
3. **Review and Update Wallet Software:** Regularly check for and apply updates for all wallet software and associated applications to patch known vulnerabilities (e.g., addressing risks from outdated wallets).
## Implementation Guidance
### For Small Organizations
* **Focus on Education:** Implement mandatory training for all personnel handling digital assets on recognizing phishing attempts and the absolute sensitivity of seed phrases.
* **Centralized Password Solution:** Adopt one reputable password manager for all employees as an immediate step toward secure credential hygiene.
### For Medium Organizations
* **Implement Dedicated Secure Devices:** For critical key management or high-value transactions, mandate the use of dedicated, air-gapped or isolated hardware devices not used for general browsing or email.
* **Formalize 2FA Policy:** Require using hardware-based security keys (like FIDO2/U2F) over app-based 2FA where supported, offering the highest level of account access protection.
### For Large Enterprises
* **Develop Incident Response Playbook:** Create a specific, tested incident response plan addressing potential digital asset compromise (e.g., internal unauthorized transfer protocols).
* **Audit Smart Contract Exposure:** If interacting with DeFi protocols, institute a rigorous auditing process for smart contract interactions before deployment or significant fund allocation.
## Configuration Examples
| Component | Configuration Best Practice | Rationale |
| :--- | :--- | :--- |
| **2FA Setup** | Use Authenticator Apps (Google Auth/Authy) or Physical Keys (YubiKey/etc.) | Avoids SIM-swapping vulnerability inherent in SMS-based codes. |
| **Wallet Access** | Set strong, unique password on software/hardware wallet interfaces. | Provides a layer of protection if the physical device or computer is briefly compromised. |
| **Transaction Signing** | Use QR codes when possible to input recipient addresses. | Minimizes manual entry errors that lead to permanent fund loss. |
## Compliance Alignment
While specific crypto security may not map directly to traditional IT compliance frameworks, the underlying principles align with:
* **NIST Cybersecurity Framework (CSF):** Controls map to **Identify** (understanding asset locations/risks), **Protect** (access control/authentication), and **Detect** (monitoring for suspicious activity).
* **ISO/IEC 27001:** Specifically aligns with requirements for **Information transfer security** (secure handling of keys/phrases) and **Access Control**.
* **CIS Critical Security Controls (v8):** Control 5 (Account Management and Access Control) and Control 10 (Data Recovery) are highly relevant to seed phrase backup and strong authentication.
## Common Pitfalls to Avoid
* **Sharing Seed Phrases:** Never share your private key or seed phrase, even if the request appears to come from "support" or a trusted entity.
* **Clicking Unsolicited Links:** Avoid clicking links in suspicious emails or messages claiming to be from exchanges or wallet providers; always navigate directly to the known official URL.
* **Relying on Centralized Custody for Long-Term Storage:** Treating exchanges as primary storage vaults exposes funds to platform-level breaches.
* **Storing Recovery Data on Internet-Connected Devices:** Do not save seed phrases in text files, emails, screenshots, or cloud storage.
* **Using Weak or Reused Passwords:** This is the lowest hanging fruit for attackers targeting credential stuffing across different platforms.
