Beyond Ledger: Five Alternatives for Storing Bitcoin
Edited by Steinar Vigdel Kolnes, Editor, Oslo
Trezor, Coldcard, BitBox02, Blockstream Jade and SeedSigner offer different approaches to holding Bitcoin private keys outside an exchange.
Ledger is one of several options for Bitcoin self-custody. Alternatives include Trezor, Coldcard, BitBox02, Blockstream Jade and SeedSigner, which differ in hardware design, connectivity and transaction-signing workflows.
Trezor offers hardware wallets supporting Bitcoin and other cryptocurrencies, while Coldcard focuses on Bitcoin. BitBox02 is available in Bitcoin-only and multi-asset editions. Blockstream Jade is another signing device that supports Bitcoin.
SeedSigner takes a different approach: it is an open-source project for building a Bitcoin signing device from off-the-shelf components, using QR codes to exchange transaction information. Across these options, bitcoin remains on the blockchain; the devices handle the keys and signatures used to authorize spending.
