What it is

Key features

• Fully open source (blockstream.com).

• Virtual secure element: keys are encrypted on the device and need a remote blind oracle plus your PIN to unlock (blockstream.com).
• Multisig support (blockstream.com).

Buying and setup

Every brand: Buy only from the maker's own official store. Even listed or authorized resellers have been compromised. In October 2026, implanted Ledger devices that captured recovery phrases during setup were sold through CryptoBilis, a reseller Ledger's own site listed as authorized for Indonesia, Malaysia and the Philippines (Galaxy Research). Never restore an existing seed onto a device you didn't buy direct from the maker. Treat any device that arrives already set up, or with a printed or pre-filled seed, as compromised. Don't use it.

• Buy only from the maker's own official store (blockstream.com), not from resellers, even ones it lists as authorized. Never use a device that arrives with a seed already written down.
• Set it up with our hardware wallet module, then pair it with Sparrow as a watch-only wallet.
