How to Achieve Self Custody
Self custody means having complete control over your digital assets without relying on third parties. Here's how to implement proper self custody with advanced security practices for you and your family.
BIP-85: Hierarchical Key Management
Master/Child Key Strategy
BIP-85 allows you to create a hierarchical wallet structure where a single master seed generates multiple child seeds. This enables secure family wallet management while maintaining centralized recovery control.
- Family Master Seed: One master seed generates all child master keys
- Unique Indices: Assign each family member a unique index (1=Dad, 2=Mom, 3=You)
- Individual Wallets: Each person derives their wallet using SeedSigner or Coldcard
- Recovery Benefits: Lost child seed can be re-derived from master + index
Implementation Steps
- Hardware Setup: Use SeedSigner or Coldcard for offline key generation
- Master Seed Creation: Generate and securely backup your master seed phrase
- Child Derivation: Use BIP-85 to create child wallets for each family member
- Wallet Configuration: Connect to Sparrow Wallet for watch-only monitoring
- Node Connection: Point wallets to our Bitcoin node for enhanced privacy
Security Best Practices
Proper self custody requires multiple layers of security and regular maintenance:
- Store seed phrases on metal or paper, never digitally
- Maintain 2+ backups in different physical locations
- Run annual recovery drills to test your backups
- Keep hardware devices updated and in good condition
- Use Taproot (bc1p...) or Segwit (bc1q...) addresses for new Bitcoin deposits
