Trezor: Crypto’s Best Renegade Hardware Wallet

Trezor Safe hardware wallets representing open-source, independent crypto self-custody and hardware security

DISCLAIMER: NOT FINANCIAL ADVICE — DO YOUR OWN RESEARCH (DYOR)

Trezor Is Crypto’s Best Renegade Hardware Wallet Company and Here’s Why

First, What Do We Mean by “Renegade”?

Not reckless. Not secretive. Not anti-establishment simply for the sake of being anti-establishment. What we mean by "renegade" is independent. 

The crypto hardware-wallet industry has become increasingly commercialized. There is nothing inherently wrong with that. Building sophisticated hardware is expensive.

But incentives matter.

Ledger has raised hundreds of millions of dollars from outside investors. Parts of Ledger's operating system remain proprietary because of restrictions associated with its Secure Element architecture.

OneKey has built an impressive open-source platform and some of the most sophisticated hardware we have evaluated, but it has also raised institutional capital from YZi Labs, Dragonfly, Ribbit Capital, Coinbase Ventures and others.

SafePal openly identifies Binance as an investor and strategic backer.

Again, investment does not make any of these companies untrustworthy.

It simply means they operate within a different incentive structure.

Trezor says it is 100% self-owned.

That matters to us.

A company protecting the cryptographic keys to potentially enormous amounts of personal wealth should ideally have as few parties as possible capable of influencing its priorities.

Why Trezor is the best hardware wallet company

Trezor's answer has essentially been:

We answer to ourselves.

That is renegade and how the Great West was won - cowboy style. And today, with all the money floating around wanting to attach itself to blockchain - this is straight baller to say, "No thanks, we'll build this company by hand one brick at a time."


Before Hardware Wallets, There Was Trezor

It is easy to forget this history because hardware wallets now seem inevitable.

They weren't. And when Bitcoin first came out it was truly The Wild West!

Trezor's founders, Marek “Slush” Palatinus and Pavol “Stick” Rusnák, began developing the concept that ultimately became the Trezor Model One. The device launched in 2014 and is generally recognized as the first commercial cryptocurrency hardware wallet.

The Motivating Force: Get Burned Once, Then Build It Better

They say hell hath no fury like a woman scorned.

Add to that: don't underestimate what happens when a technically gifted Bitcoin founder with a strong moral compass gets burned by the very custody problem he is trying to solve.

That may be one of the most important pieces of the SatoshiLabs story.

Before Trezor existed, Marek “Slush” Palatinus had already created another Bitcoin first: Slush Pool, the world's first publicly available Bitcoin mining pool. As the pool grew, so did the attention from hackers. SatoshiLabs' own history says Slush Pool became an increasingly attractive target, creating an urgent need to improve not only the security of the pool, but Bitcoin custody itself.

Then, in March 2012, the theoretical problem became painfully real.

Cloud-hosting provider Linode was compromised, and attackers stole 3,094 BTC from Marek Palatinus' wallet associated with Slush Pool. Contemporary reporting from Ars Technica confirmed the theft directly with Palatinus.

But what happened next tells us considerably more about the people who would eventually create Trezor.

The loss affected funds belonging to the mining pool. According to the Slush Pool/Braiins account of the incident, passing that loss on to the miners wasn't considered an acceptable solution. Slush covered the loss from his own personal savings.

Think about that for a moment.

He didn't merely read about someone losing Bitcoin.

Make note, Palatinus, didn't watch Mt. Gox collapse from the sidelines and decide there might be a market opportunity. He experienced firsthand what happens when valuable private keys depend on an online environment that can be compromised—and then personally absorbed the financial consequences rather than shifting them onto his users.

That distinction matters to us!

We can't climb inside the founders' heads and declare that one event explains everything SatoshiLabs has done since. In fact, SatoshiLabs says Marek and Pavol Rusnák initially explored hardware-wallet concepts out of curiosity and interest rather than business motivation after meeting at Prague's brmlab hackerspace in 2011.

But history gives us a pretty compelling picture of the forces shaping the company.

Experience the custody failure.

Make your users whole.

Then engineer the problem out of the system.

AND WE EFFING LOVE IT!

That pattern helps explain why Trezor has always felt different to us.

The company didn't begin with a pitch deck asking how to capture market share in an emerging hardware-wallet category. There was no hardware-wallet category to capture.

There was a security problem.

And the people who became SatoshiLabs decided to build the solution.

We think that origin story still echoes through the company today. It helps explain the obsession with open-source firmware. It helps explain the work on BIP39, BIP44 and SLIP39. It helps explain why SatoshiLabs eventually concluded that existing proprietary Secure Elements were not transparent enough and helped create Tropic Square rather than simply accepting the industry's black-box model.

SatoshiLabs now describes itself as a group of “cypherpunks,” “fearless reformers,” and industry founders committed to maintaining their mission through self-funded businesses. Its manifesto explicitly ties its existence to individual autonomy, privacy, freedom to transact and the right to own property.

Normally, corporate manifestos are marketing material. In this case, there is more than a decade of engineering history behind the words. So when we try to understand the motivating force behind SatoshiLabs, we don't think it is simply:

Sell hardware wallets.

We think it is closer to:

Nobody should have to experience what we experienced simply because the tools to protect themselves don't exist. If the tools aren't good enough, build better ones. If the standards don't exist, create them. If the security hardware isn't transparent enough, build that too.

That is a very different corporate DNA... and we effing love it!

And it may be the single best explanation for why, more than a decade later, Trezor still behaves like the renegade in an industry it helped create.

The fundamental idea seems obvious today:

Keep the private keys off the Internet.

At the time, it wasn't an established consumer product category.

Note this: Trezor didn't enter the hardware-wallet industry. Trezor helped create it.

That history matters because the same pattern appears repeatedly throughout the company's development and Research Labs doesn't think enough pundits are writing about this.

When Trezor believes self-custody infrastructure needs something, it has repeatedly been willing to build it.


They Didn't Just Build Wallets. They Helped Build the Standards.

This is one of the most underappreciated parts of the SatoshiLabs story.

Marek Palatinus and Pavol Rusnák were among the authors of BIP39, the mnemonic recovery-word standard now used throughout the cryptocurrency industry. The final BIP39 specification lists Palatinus, Rusnák, Aaron Voisine and Sean Bowe as authors.

Palatinus and Rusnák also authored BIP44, establishing the multi-account hierarchy that allows deterministic wallets to organize different cryptocurrencies, accounts, receiving addresses and change addresses predictably.

Then came SLIP39.

Instead of simply accepting a single recovery phrase as the end state of backup security, SatoshiLabs engineers developed an interoperable implementation of Shamir's Secret Sharing for hierarchical deterministic wallets.

The SLIP39 specification was authored predominantly by SatoshiLabs engineers and was designed so that a secret could be divided among multiple shares and reconstructed only when a predefined threshold was met.

Think about the pattern:

Hardware wallet needed? Build it.

Recovery-word standard needed? Help build it.

Multi-coin derivation standard needed? Build it.

More sophisticated backup architecture needed? Build it.

That is not simply a hardware company shipping another plastic box.

It is an engineering organization that has repeatedly influenced the underlying architecture of self-custody.


Then Trezor Did Something Even More Renegade

For years there was an uncomfortable tradeoff in hardware wallets.

You could have openness. Or you could use a highly hardened proprietary Secure Element whose deepest workings were protected by NDAs and unavailable for public inspection.

Ledger embraced the latter model.

Ledger itself explains that portions of the low-level software interacting with its Secure Elements cannot be published because of contractual restrictions imposed by the chip manufacturer.

Trezor historically resisted that model and the world is better for it. Instead of simply surrendering to the industry's existing Secure Element choices, SatoshiLabs helped create another company:

Tropic Square.

Tropic Square's mission was audacious:

Build an auditable Secure Element.

TROPIC01 uses an open architecture built around RISC-V and was designed so researchers and customers could inspect far more of the hardware security architecture instead of simply trusting a sealed black box. Tropic Square explicitly describes its philosophy as replacing security through obscurity with independently verifiable hardware.

Tropic Square is a SatoshiLabs company.

That is extraordinary.

Most wallet manufacturers select chips.

SatoshiLabs helped create a semiconductor company because it disagreed with the trust model of the chips available to it.

If “renegade hardware-wallet company” needs a definition, that might be it.


And Then Ledger Broke Their Chip

Good. Seriously. Because, this is where the open-security philosophy gets tested.

Tropic Square provided TROPIC01 samples to Ledger Donjon, the security research division of one of Trezor's largest competitors.

Ledger's researchers attacked it.

In late January 2026, they succeeded.

TROPIC01 Chip by TropicSquare

Using laser fault injection, Donjon bypassed TROPIC01's firmware-signature verification and achieved arbitrary firmware execution. Tropic Square subsequently identified additional implications and began hardening the next silicon revision. The vulnerability was publicly disclosed on June 3, 2026.

That sounds terrible. But from a narrow chip-security perspective, it is a flaw.

From an organizational-trust perspective, however, something important happened:

The system worked!

✓ The chip was designed to be examined.

✓ Samples went to elite external researchers.

✓ A competitor's security laboratory broke it.

✓ The findings were coordinated and disclosed.

✓ The weakness was documented.

✓ The architecture is being revised.

Tropic Square says hardened silicon designed to mitigate this particular attack is scheduled for delivery toward the end of 2026.  That is what open security is supposed to look like. The objective is not to create hardware nobody ever finds a vulnerability in. That hardware does not exist!

The objective is to create an ecosystem in which vulnerabilities can be discovered, investigated, disclosed and engineered out.

Trezor's Safe 7 also uses three hardware layers from different sources: TROPIC01, an Infineon OPTIGA Trust M EAL6+ Secure Element, and an STM32U5 security MCU. A compromise of TROPIC01 alone therefore does not provide the complete secret set needed to defeat the Safe 7's overall PIN-protection architecture.

We still want the revised TROPIC01 silicon.

But the fact that researchers broke the first generation does not make us trust Trezor less. Trying to hide the problem would have.


Trezor Safe 3

Where We Disagreed With Trezor and What Changed

Trust does not mean refusing to criticize a company you respect.

And Trezor made a decision with the Safe 3 that Research Labs believes was inconsistent with the standards the company sets for itself.

Ledger Donjon evaluated the original Trezor Safe 3 and reported its findings on November 12, 2024.

Researchers demonstrated that a previously known attack could bypass some of the original Safe 3's supply-chain countermeasures.

Trezor acknowledged that the Safe 5 was not affected because it used a newer microcontroller designed to provide greater resistance to that type of attack.

Trezor later produced a newer Safe 3 revision using the more resistant STM32U5 MCU.

The original Safe 3 identifies internally as T2B1.

The newer revision identifies as T3B1.

So far, fine.

Hardware evolves.

What we disagree with is what happened next...

In March 2026, a Trezor firmware developer responding through Trezor's official community forum confirmed that the older T2B1 revision had been out of production “for quite some time,” but said older inventory could still remain in stock and that buyers could not be guaranteed the newer revision. 

Most importantly:

Trezor considered T2B1 and T3B1 the same product. We don't.

Yes, Trezor maintained that the older device remained secure because extracting encrypted seed material from the MCU did not defeat the separate Secure Element protection.

That is an important technical distinction.

But from a consumer perspective the issue is simpler.

There was:

an older architecture with a known weakness and a newer architecture specifically more resistant to that attack class. Don't sell me old shi% at the new price.

A customer buying a security product should know which one they are receiving.

Research Labs believes Trezor should have stopped selling the remaining Rev. A devices.

Take the inventory loss - Write them off - Destroy them - Use them internally - Donate them for research.

But once you have produced the improved security architecture, don't make a customer unknowingly take the older one so you can clear the shelf. That moral compass has a crooked tip.

For an ordinary consumer-electronics company, that decision would be disappointing.

For Trezor, it was worse. Why?

Because Trezor's independence is part of its argument for trust.

The company explicitly says being self-funded and free of outside investors allows it to prioritize security, privacy and control without external financial pressure.

That creates a higher standard.

If you don't have venture investors demanding margins and quarterly growth, then occasionally you should be willing to eat the loss when security evolves faster than inventory.

We think Trezor should have done exactly that.


Why That Doesn't Change Research Lab's Conclusion

Trust is not believing a company never makes a questionable decision.

That would be fandom.

Research is asking what happens over time.

What does the company build?

What incentives govern it?

How does it respond when researchers find something?

How much of its technology can outsiders inspect?

Does it contribute back to the larger self-custody ecosystem?

And when the market doesn't offer the infrastructure it believes users need, what does it do?

Trezor's record is unusual.

It helped create the hardware-wallet category.

Its founders helped create fundamental wallet standards.

It has maintained an open-source philosophy from the beginning; Trezor says its device software has always been open-source and publicly auditable.

It developed new backup standards.

It remained self-owned.

It remained self-funded.

And eventually, SatoshiLabs decided that the Secure Element industry's black-box model wasn't good enough and helped build a semiconductor company to challenge it.

That is an entirely different corporate personality from:

Which chip can we buy?

Which investor can fund our next round?

Which ecosystem integration increases revenue?

Those questions are legitimate.

Trezor simply appears willing to ask another one first:

What should self-custody look like if we build it according to our principles?


This Does Not Mean Every Trezor Is Technically #1

This distinction is important.

Research Labs is not saying every Trezor wins every hardware-wallet comparison.

It doesn't.

OneKey Pro has an extremely interesting four-Secure-Element architecture and an unusually strong approach to keeping sensitive key operations inside its Secure Elements.

Keystone 3 Pro provides genuine QR-based air-gapped transaction signing and a strong multi-chain experience.

Other wallets may outperform Trezor in individual areas such as chain support, portability, air-gap architecture, transaction workflow or Secure Element design.

And the current Safe 7 still uses the first-generation TROPIC01 silicon affected by the disclosed laser fault-injection weakness. The hardened revision is expected later.

Those things matter.

But device architecture and company architecture are different questions.

Black Seed Ink's Research Lab can find technically impressive hardware. What is much harder to find is another major multi-chain hardware-wallet company combining:

No outside investors.

Self-funding.

Open-source development as a founding principle.

More than a decade of hardware-wallet development.

Direct contributions to foundational wallet standards.

A willingness to create new open standards.

And participation in building an auditable Secure Element rather than simply accepting the industry's existing trust model.

That combination is why our assessment changes when the question becomes:

Which company do we most trust to remain philosophically aligned with self-custody ten years from now?

Our answer is Trezor #1 - end of discussion.
