Ledger Start — Security Model & Long-Term Custody

In-depth

An in-depth article focused on the security design behind ledger start and strategic choices for protecting assets over years and generations.

Threat Model: What Ledger Start Mitigates

Ledger Start aims to minimize exposure to remote compromise by keeping private keys on a tamper-resistant device. Key threats addressed include: malware on host device, phishing sites, and remote key extraction.

Residual Risks

  • Physical theft of device + compromise of recovery phrase
  • User mistakes (writing recovery phrase to cloud)
  • Supply-chain tampering in rare cases

Hardening Strategies

Device-level

  • Keep firmware up to date via official channels
  • Validate device attestation where available

Operational

  • Use separate machines for high-value transactions
  • Keep recovery phrase offline and consider metal backups

Policy & Governance Considerations

For institutions, ledger start is often the first step before implementing multisig policies, vaults, and split custody. Policies should define roles, approval thresholds, and clear recovery procedures.

Note: Hardware wallets are a tool — effective security combines technology, policy, and human processes.

Frequently Asked — Long-form Answers

Should I use a passphrase?

Passphrases add a layer of secrecy but also increase complexity: losing a passphrase can render funds irrecoverable. Understand trade-offs and adopt robust backup and access plans if you use one.

How should heirs access crypto (estate planning)?

Plan in advance: include legal, technical, and physical instructions. Consider multisig or legally-enforced custodial arrangements if appropriate. Never store full recovery data in a single, unprotected location.
