Purpose and scope
Ledger Start™ is a deterministic, verifiable setup flow engineered to minimize attack surface during device provisioning. This technical guide assumes familiarity with cryptographic primitives, hardware-backed key storage, and basic CLI/GUI tooling. Use it to: initialize devices, verify firmware authenticity, generate and protect seed material, configure optional passphrases, and integrate with Ledger Live® in a secure, reproducible manner.
Core security primitives
Ledger® devices rely on a certified Secure Element (SE) to store private keys and execute transaction signing within an isolated environment. The SE enforces secure boot, firmware authentication, and sealed storage for key material. Ledger Start™ builds procedural controls around these primitives — attestation of device firmware, deterministic recovery phrase generation, and out-of-band proofing where applicable — to ensure the private key never materializes in host memory.
Verified provisioning workflow
Follow these reproducible steps when provisioning a device for production or personal use:
- Supply chain check: Confirm packaging tamper-evidence and compare device serial numbers with vendor records when available.
- Download tools: Fetch Ledger Live® only via Ledger.com; validate installer signatures if you maintain a secure build system.
- Initialize offline: Prefer initializing in an air-gapped environment. Create the PIN and generate the 24-word recovery phrase directly on the device screen.
- Seed handling: Record the 24-word mnemonic onto hardware-grade media (metal plate, secure backup) using a write-once process; never store seeds digitally or in cloud backups.
- Firmware attestation: Verify firmware versions and attestation proofs exposed by the device against Ledger’s published fingerprints. Reject any unrecognized firmware hashes.
- Optional passphrase: Use deterministically for hierarchical wallets where plausible deniability or account separation is required. Manage passphrase derivation with care — it is effectively an extension of the private key.
- Test vector transfer: Submit a minimal transaction as a sanity test; validate the signed transaction payload against expected outputs before funding at scale.
Advanced integration patterns
Ledger Start™ supports production-grade integrations: hardware security module (HSM) complement, multisignature coordination, and programmatic device provisioning for custodial and enterprise workflows. Use the following patterns:
- Multisig deployments: Combine multiple Ledger devices with cosigners to reduce single-point-of-failure risk.
- Air-gapped signing: Maintain an isolated signer for transaction approvals; transfer unsigned transactions via QR or USB-in-OTG media.
- CI/CD checks: Validate Ledger Live® installer hashes in your provisioning pipeline and pin approved versions for deterministic rollouts.
Operational security checklist
Practical operator controls to lower risk:
- Preserve seed secrecy: no photographs, no cloud backups, and at least two geographically-separated metal backups.
- Authenticate updates: only accept firmware updates and apps validated by Ledger® and verified within Ledger Live®.
- Least privilege hosts: connect devices to hardened hosts with minimal software footprint when performing sensitive operations.
- Audit and rotate: periodically audit access, and for enterprise use, rotate cosigner devices or rotate keys tied to operational personnel.
Ledger Live® and ecosystem interoperability
Ledger Live® remains the primary sanctioned interface for installing apps, managing accounts, and orchestrating transactions. For programmatic or advanced flows, integrate using well-known Web3 providers that support Ledger® device communication. Always confirm contract addresses and binary payloads in a separate channel before approving large-value operations on-device.
Open Ledger Start™Incident response & recovery
If a device is lost, corrupted, or suspected compromised, follow a strict recovery workflow: revoke on-chain approvals (where applicable), move funds from affected addresses to new derivations generated from a fresh, securely-initialized device, and re-provision any multisig cosigners. Ledger Start™ provides guidance for safe migrations and recommends contacting official Ledger® channels for attestation or firmware anomalies.
