Ledger is the default, and it is a fine device. People look for alternatives for three reasons: they want firmware they can read, a real air gap instead of a USB cable, or they do not want to buy a device at all. Here is every serious option for Solana, with the reason you would pick each.
| Price | Key at rest | Transaction path | Source | |
|---|---|---|---|---|
| Coldstar | ~$10 drive; software free | AES-256-GCM file; RAM-only while signing | QR; fully air-gapped | MIT |
| Trezor | $59 (Safe 3), $129 (Safe 5) | EAL6+ secure element | USB-C; not air-gapped | Firmware GPL-3.0 |
| Keystone 3 Pro | $149 | Three secure elements | QR + microSD; air-gapped | Published; one pre-compiled MCU library |
| OneKey | $99 (Classic 1S), $278 (Pro) | One to four EAL6+ secure elements | USB/Bluetooth; Pro adds QR air gap | Open, reproducible firmware |
| SafePal S1 | $49.99 (S1), $89.99 (S1 Pro) | EAL6+ secure element | QR only; air-gapped | Partially open |
| Tangem | $59.90 for two cards | EAL6+ card, non-updatable firmware | NFC tap via the online phone | App open; card firmware closed |
| ELLIPAL Titan 2.0 | $149 | EAL5+ secure chip | QR only; air-gapped | Closed |
| Cypherock X1 | Not listed on the store page | 5-way Shamir split across EAL6+ cards | USB-C; not air-gapped | MIT + Commons Clause |
| GridPlus Lattice1 | $397 | PUF secure enclave | Wi-Fi / Ethernet; always online | SDK open; firmware as signed binaries |
Short cells; the linked pages carry the detail and the sources. Coldstar is beta software with an independent audit planned before its production release, and that is stated on every page.
Yes. Trezor publishes its firmware under GPL-3.0, OneKey publishes reproducible firmware, Keystone publishes most of its firmware, and Coldstar is MIT-licensed software. Ledger's device apps are open but its operating system is not.
Keystone 3 Pro, SafePal S1, OneKey Pro, and ELLIPAL Titan sign over QR codes with no data connection. Coldstar does the same in software on an offline computer. Trezor, Cypherock, and Ledger itself sign over USB.
Coldstar is free software plus any USB drive. Among devices, SafePal S1 at $49.99 and Trezor Safe 3 at $59 are the lowest-priced options with a secure element.
Only Coldstar is designed for unattended, policy-gated signing. Every hardware wallet here requires a physical confirmation per transaction.
Open source, MIT. macOS, Linux, Windows — and on the Solana Seeker dApp Store.
