Ledger & Co. — custody and tools for modern digital finance
We build secure wallet infrastructure, hardware-backed custody, and user-friendly portfolio tools so individuals, teams, and institutions can own cryptocurrency responsibly. Ledger & Co. blends rigorous security engineering with polished UX — custody you can trust, interfaces people actually use.
Our philosophy — custody, clarity, and control
Ledger & Co. was founded with a clear premise: owning digital assets requires both strong technical custody and a human-centered interface. Too many security tools are either impenetrable or insecure. We design for the intersection of those needs — devices and software that minimize user error while maximizing cryptographic protection. Whether you're an individual securing your first BTC or a treasury team managing multisig, we believe a sensible security posture should be accessible and auditable.
Our product suite deliberately separates the signing boundary from the presentation layer. The host application provides visibility, analytics, and integration capabilities; the device handles key generation and signing in an isolated environment. This design reduces attack surface, supports regulatory requirements, and enables a range of custody models from single-signer hardware to multisig and HSM-assisted patterns.
Products & Services
Ledger & Co. offers modular products that scale with your needs:
- Hardware Wallets — tamper-resistant devices with certified secure elements for private key custody.
- Ledger Portal — desktop and mobile portfolio manager with on-device signing, NFT gallery, staking dashboards, and swap integrations.
- Developer SDKs — transports and signing libraries (WebHID, WebUSB, Node HID) plus sample integrations for straightforward dev adoption.
- Enterprise Suite — multisig integrations, device inventory, audited firmware rollout, and policy-driven operation for teams.
Security model & architecture
Security is layered. Our Secure Element provides the root of trust: cryptographic keys are generated and used only inside the component. The device firmware enforces PIN policies, anti-tamper measures, and on-screen verification. Ledger & Co.'s software acts as an orchestrator — it aggregates balances, fetches market data, and builds unsigned transactions that the device will validate and sign. Updates are signed and verifiable to reduce supply-chain risks.
Enterprise & Teams
For businesses and DAOs, Ledger & Co. provides device provisioning workflows, multisig integrations, and policy-driven operational controls. We support inventory tracking for devices, firmware governance, and role-based access for signing operations. Combine hardware devices with multisig for treasury-grade protection and human-in-the-loop approvals for sensitive transfers.
Frequently asked questions
- Is Ledger & Co. a custodian?
- Ledger & Co. provides tools and devices for self-custody and enterprise custody patterns; we do not hold user private keys for standard consumer devices. Enterprise offerings can include custody services under explicit contractual terms.
- What happens if I lose my device?
- Devices are recoverable using the 24-word recovery phrase you recorded during setup. If a passphrase was used, you must also provide that passphrase to recover the exact accounts.
- Can I integrate Ledger & Co. into my web app?
- Yes — we publish SDKs and transport libraries for web and native apps. Follow our developer docs to implement secure signing flows and test thoroughly on testnets.
- How do I verify firmware and downloads?
- Always download software from official links, verify checksums where provided, and only accept firmware updates signed by the device vendor. For enterprise, maintain central verification and deployment procedures.
