1. Introduction: The French Hardware Wallet Dilemma
Ledger is technically excellent but legally vulnerable to French government requisitions.
Choosing a hardware wallet is no longer solely a technical question. In the French regulatory context of 2025-2026, it has become a strategic decision with a legal dimension.
1.1 The Ledger Paradox
Ledger SAS is the undisputed global leader in hardware wallets. The French company has sold more than 6 million devices worldwide. Its Secure Element technology is considered the industry benchmark.
But this technical excellence collides with a legal reality: Ledger is a French company, subject to French law.
Central question: Can a hardware wallet manufactured by a company subject to French government requisitions guarantee the sovereignty of your assets?
1.2 What the LPM Changes
The Military Programming Law 2024-2030 (article 47) now allows the French government to requisition:
- Any French legal entity
- Its assets, services, and infrastructure
- By simple decree of the Council of Ministers
"In the event of a threat [...] affecting activities essential to the life of the Nation [...], the requisition of any person, natural or legal, and of all goods and services necessary to address it, may be decided by decree of the Council of Ministers."

2. Manufacturer Map by Jurisdiction
From France to Canada: the manufacturer's jurisdiction defines your regulatory exposure.
2.1 Global Overview
| Manufacturer | Country | Jurisdiction | Open Source | Secure Element |
|---|---|---|---|---|
| Ledger | France | EU + France | No (closed firmware) | Yes |
| Trezor | Czech Republic | EU | Full | No |
| Coldcard | Canada | Non-EU | Full | Yes |
| Foundation | USA | Non-EU | Full | Yes |
| Keystone | Hong Kong | Non-EU | Partial | Yes |
| BitBox02 | Switzerland | Non-EU | Full | Yes |
| Jade | USA | Non-EU | Full | No |
2.2 Jurisdictional Implications
French jurisdiction (Ledger):
- Subject to the LPM and government requisitions
- Mandatory cooperation with French authorities
- Article 230-1 CPP: criminal penalties for refusing to decrypt
- Personnel and executives under direct jurisdiction
EU jurisdiction outside France (Trezor, BitBox):
- Not subject to the French LPM
- European judicial cooperation possible but slower
- No obligation to cooperate directly with French authorities
- European Arrest Warrant required to compel executives
Non-EU jurisdiction (Coldcard, Foundation, Keystone):
- Beyond the reach of European requisitions
- Cooperation only through international treaties
- Significantly longer procedures and timelines
- Potential diplomatic protection
3. In-Depth Ledger Risk Analysis
Ledger Recover demonstrates that key extraction is technically possible.
3.1 Technical Architecture
Ledger uses a two-tier architecture:
+---------------------------------------------------+
| MICROCONTROLLER (MCU) |
| - Display management |
| - USB/Bluetooth communication |
| - User interface |
| - CLOSED SOURCE FIRMWARE |
+---------------------------------------------------+
|
v
+---------------------------------------------------+
| SECURE ELEMENT (SE) |
| - Private key storage |
| - Cryptographic operations |
| - EAL5+ certified |
| - CLOSED SOURCE FIRMWARE |
+---------------------------------------------------+
Critical point: Neither the MCU firmware nor the SE firmware is open source. It is therefore impossible to verify what the device is actually doing.
3.2 Ledger Recover: The Technical Proof
The Ledger Recover service, launched in 2023, technically demonstrates that:
- The Secure Element can export the seed phrase: Contrary to marketing claims, keys can leave the device
- The firmware can be modified: An update can enable unwanted features
- Extraction is controllable: The mechanism exists and works
"Ledger Recover demonstrates that the architecture allows key extraction. The question is no longer technical — it is political."

3.3 Compromise Scenarios
Scenario 1: General Requisition
- The government requisitions Ledger SAS
- Deployment of an extractive update for all devices
- Mass seed collection
Probability: Low (major political impact)
Scenario 2: Targeted Requisition
- The administration identifies a specific taxpayer
- Targeted judicial or administrative requisition
- "Personalized" firmware update for that unique device
- Extraction at the next connection
Probability: Medium (legally possible, technically feasible)
Scenario 3: Vulnerability Exploit
- Discovery of a flaw in the closed source firmware
- Exploitation by a malicious actor (state or criminal)
- No community verification possible
Probability: Unknown (impossible to assess without audit)
3.4 Ledger's Official Response
Ledger has consistently stated:
- "The Secure Element physically protects the keys"
- "We cannot access our users' keys"
- "Ledger Recover is optional and requires consent"
Critical analysis:
- The very existence of Recover proves the technical capability
- What is optional can become mandatory via a forced update
- Consent can be overridden by a legal requisition
4. Trezor: The European Open Source Alternative
100% open source from the Czech Republic: total transparency, but still within the EU.
4.1 Overview
Manufacturer: SatoshiLabs s.r.o. Headquarters: Prague, Czech Republic Founded: 2013 (first commercial hardware wallet)
4.2 Technical Architecture
+---------------------------------------------------+
| SINGLE MICROCONTROLLER |
| - STM32 (standard processor) |
| - No Secure Element |
| - 100% OPEN SOURCE FIRMWARE |
| - Personal compilation possible |
+---------------------------------------------------+
4.3 Advantages
| Aspect | Assessment |
|---|---|
| Transparency | Full source code is verifiable |
| Compilation | Users can compile the firmware themselves |
| Updates | Optional and verifiable |

4.5 Legal Risk
Since the Czech Republic is an EU member:
- European Arrest Warrant applicable to executives
- Judicial cooperation via Eurojust
- But procedures are longer and more complex than in France
- No direct requisition possible by France
5. Coldcard: The Canadian Fortress
Open source, Secure Element, and Canadian jurisdiction: the winning combination.

6. Foundation Passport: The Sovereign American
Created in reaction to Ledger Recover: Bitcoin sovereignty above all.
6.1 Overview
Manufacturer: Foundation Devices Inc. Headquarters: Boston, Massachusetts, USA Founded: 2020
6.2 Philosophy
Foundation was created specifically in response to concerns raised by Ledger Recover:
"We believe in Bitcoin, not Bitcoin-adjacent business models. Foundation is 100% focused on Bitcoin sovereignty."
Source: Foundation Devices, mission statement
6.3 Technical Specifications
| Aspect | Specification |
|---|---|
| Firmware | 100% open source |
| Secure Element | Microchip ATECC608A |
| Connectivity | Air-gapped (QR camera) |
| Build | CNC-machined aluminum, manufactured in the USA |
| Battery | Removable, standard AAA |
| Screen | Color, high resolution |
6.4 Legal Advantages Specific to the USA
| Aspect | Assessment |
|---|---|
| First Amendment | Freedom of speech protection (code = speech) |
| Apple vs FBI precedent | Public resistance is possible |
| Jurisdiction | Outside the EU, outside direct European treaties |
| Extradition | Complex and political |
The Apple vs FBI precedent (2016): Apple refused to create a tool to unlock the iPhone of a terrorist. The US government ultimately backed down, unable to legally compel Apple.
This precedent suggests that an American company could resist demands to create a backdoor.

9. Strategic Recommendations
The three-tier architecture: compliant storefront, intermediate protection, and total sovereignty.
9.1 Multi-Level Protection Architecture
Level 1: Visible Compliance
- Small amount on Ledger or a French exchange
- Impeccable tax declarations
- A compliant "storefront" for authorities
Level 2: Intermediate Protection
- Coldcard or Foundation for the bulk of assets
- Personally verified firmware
- Air-gapped operations
Level 3: Total Sovereignty
- DIY SeedSigner for critical keys
- Component of a distributed multisig
- No traceable supply chain
9.2 Cross-Cutting Best Practices
| Practice | Importance |
|---|---|
| Verify firmware before every update | CRITICAL |
| Never activate cloud services (Recover, etc.) | CRITICAL |
| Use air-gapped mode when available | RECOMMENDED |
| Diversify manufacturers in a multisig | RECOMMENDED |
| Order to a non-personal address | OPTIONAL |
9.3 What NOT to Do
- Blindly trust any manufacturer — even open source ones
- Concentrate everything on a single device — single point of failure
- Ignore security updates — but verify them before applying
- Use a Ledger for sensitive amounts — in the current French context
- Believe the hardware wallet is sufficient — security is multi-layered
