Compare Bitcoin Hardware Wallets

Compare COLDCARD with Trezor, Ledger, BitBox, and other hardware wallets across signing workflows, connectivity, asset support, recovery tools, and price.

Considering Trezor, Ledger, or BitBox?

These signing devices serve a similar purpose—keeping private keys separate from a phone or computer—but differ in connectivity, asset support, software dependency, and recovery tools.

Trezor

COLDCARD is a Bitcoin-only alternative to Trezor for buyers who want QR or MicroSD signing without a direct electronic connection to the coordinator during signing. Trezor Safe 7 supports a broader connected experience and can use either universal or Bitcoin-only firmware.

Ledger

COLDCARD is a Bitcoin-only alternative to Ledger for buyers who prefer QR or MicroSD signing and firmware they can independently build and verify. Ledger Nano X and Flex prioritize multi-asset support and Ledger Wallet integration.

BitBox02

COLDCARD and BitBox02 both publish firmware source and offer Bitcoin-focused options. BitBox02 is a compact USB-C device; COLDCARD adds QR or MicroSD PSBT signing plus Seed XOR, BIP-85, and configurable Trick PIN workflows.
