Is Ledger or Trezor safer?

Both are considered safe for self-custody, but they take opposite approaches. Ledger relies on a certified Secure Element chip whose firmware is closed-source. Trezor uses a general-purpose microcontroller with fully open-source firmware. Ledger's chip has never been remotely compromised; Trezor devices have been shown to leak seeds via physical voltage-glitching attacks that require the attacker to have the device in hand.

What is the main difference between Ledger and Trezor?

The core difference is the security chip. Ledger uses a Secure Element (EAL5+/6+ certified) that resists physical extraction but is closed-source. Trezor uses an open-source MCU (and adds an optional Secure Element on the Safe 3 and Safe 5) so the entire stack is auditable, at the cost of weaker resistance to physical seed extraction on older models.

Does Trezor support as many coins as Ledger?

No. Ledger supports 5,500+ coins and tokens natively through Ledger Live and third-party apps. Trezor supports around 1,800, and notably does not natively support XRP, Cardano or Solana on all models. If you hold a wide long-tail portfolio, Ledger has broader coverage.

Which is cheaper, Ledger or Trezor?

Entry-level pricing is similar. Trezor Safe 3 is about $79 and Ledger Nano S Plus is about $79. At the top end, Ledger Stax and Flex reach $279–$399, while Trezor Safe 5 sits at $169.

Security architecture

Ledger: Secure Element, closed firmware

Every Ledger device stores your seed inside a Secure Element — the same class of tamper-resistant chip used in passports and payment cards. Physical attacks like voltage glitching, side-channel analysis or chip decapping are dramatically harder against an SE than against a general-purpose MCU. The trade-off is that Ledger cannot open-source the SE firmware because the chip is under NDA with its manufacturer. You are trusting Ledger not to ship a malicious firmware update.

Trezor: open MCU, auditable firmware

Trezor devices historically stored the seed on a general-purpose STM32 microcontroller. The advantage: every line of firmware is public and reproducibly built. The disadvantage: with the device in hand, researchers have repeatedly extracted seeds via voltage glitching (Kraken Security Labs on the One, and Unciphered on the Trezor T). The newer Safe 3 and Safe 5 add a Secure Element to close that gap while keeping the firmware open.

Security incident history

Neither device has ever been remotely hacked — the incidents that hit each brand tell you what the realistic risk actually looks like.

Ledger (2020): e-commerce database breach leaked ~1M customer emails and ~270K physical addresses, kicking off years of targeted phishing and even wrench-attack threats. The devices themselves were not compromised.
Ledger (2023): Connect Kit supply-chain attack drained ~$600K from dApp users via a compromised npm package — a software integration issue, not a device compromise.
Ledger Recover (2023): optional key-shard backup service triggered a major community backlash over the principle that a firmware update could, in theory, expose the seed to third parties.
Trezor One (2020): Kraken Security Labs demonstrated a voltage-glitching attack that extracts the seed in ~15 minutes with physical access.
Trezor T (2023): Unciphered publicly extracted a seed from a Trezor T via physical voltage glitching.

Which one should you pick?

Pick Ledger if…

• You hold a broad long-tail portfolio (XRP, SOL, ADA, thousands of tokens).
• Your threat model is physical theft, not a malicious vendor update.
• You want the largest ecosystem of dApps and mobile Bluetooth support.

Pick Trezor if…

• Open-source firmware you can independently audit is non-negotiable.
• You mostly hold BTC and majors, and want the lowest-risk vendor model.
• You prefer a company with no history of customer-data breaches.
