Understanding Self-Custody Risks
Unlike traditional bank accounts, decentralized digital assets like Bitcoin, Bitcoin Cash, and Ethereum operate on peer-to-peer principles. This means you are solely responsible for securing access to your funds through:
- Private keys (24-word seed phrases)
- Wallet passwords/PINs
- Device-based authentication (biometrics)
⚠️ Critical Reminder: No third party—including wallet providers—can recover lost credentials. Losing access means permanent loss of assets.
Essential Security Measures
1. Wallet Backup Strategies
Option A: Cloud Backup (Recommended for Beginners)
- Navigate to Settings > Backup & Security > Cloud Backup
- Create a unique encryption password (never reuse other passwords)
- Securely store this password offline—it decrypts your iCloud/Google Drive backup file
Option B: Manual Seed Phrase Backup
- Each wallet generates a 12-24 word recovery phrase
- Write phrases by hand on acid-free paper
- Store multiple copies in geographically separate locations (e.g., home + safety deposit box)
- Never digitize or photograph seed phrases

2. Password Management Protocol
| Do's | Don'ts |
|---|---|
| Use password managers for cloud backups | Store seed phrases digitally |
| Create distinct passwords for each wallet | Share credentials via messaging apps |
| Enable 2FA on associated email accounts | Keep all backups in one location |
Proactive Security Practices
- Multi-Signature Wallets: Require 2+ devices to authorize transactions
- Regular Verification Checks: Periodically test backup restoration
- Air-Gapped Devices: Use dedicated offline devices for high-value transactions
