Ledger Statement: Not Affected by Coldcard Mk3 Seed Vulnerability
Ledger issued a statement saying its devices are not affected by the recently announced Coldcard Mk3 security advisory.
Ledger devices use a certified True Random Number Generator (TRNG) built into a secure element chip, generating complete 256-bit entropy for each 24-word recovery phrase; the company also pointed to Coinkite's security advisory regarding specific Coldcard Mk3 firmware versions.
The hardware wallet seed generation vulnerability has triggered a chain reaction in the industry, with Ledger emphasizing its security through technical architecture differences. The incident has driven users to accelerate the review of entropy sources and firmware history for self-custody devices, while unaffected brands gain short-term trust diversion.

Ledger has long positioned its secure element and certified TRNG as core selling points. In light of the Coldcard Mk3 (and some subsequent models) seed entropy issue, it quickly delineated its position, continuing its differentiated competition with open-source hardware wallets in random number generation pathways.
In terms of capital and product pathways, after the vulnerability exposed risks of software/firmware RNG fallback, vendors with independent secure elements and certified entropy sources can strengthen the narrative of "hardware-level isolation." The motivation is to convert the industry's trust crisis into an increase in their market share while encouraging users to migrate from single-device setups to multi-signature or higher entropy practices.
Comparing to past controversies over Ledger's own recovery phrase leaks and security incidents involving competitors like Trezor, the current phase is one of upgrading hardware wallets from "brand trust" to "verifiable entropy sources and firmware audits."
Essentially, this is a technological substitution: as the randomness of seed generation becomes a single point of failure that can be exploited, solutions with certified hardware RNG gain structural advantages, forcing the entire self-custody hardware sector to elevate the credibility of entropy sources from a default assumption to a core metric that must be publicly verified.
