Ledger clarifies how its firmware works after deleted tweet controversy By Cointelegraph

On May 18, crypto hardware wallet provider Ledger clarified how its firmware works after a controversial May 17 tweet was deleted by the company. The deleted tweet, which Ledger said was written by a customer support agent, had stated that it was “possible” for Ledger to write firmware that could extract users’ private keys.

Ledger chief technology officer Charles Guillemet clarified in a new Twitter thread that the wallet’s operating system (OS) requires the consent of the user anytime “a private key is touched by the OS.” In other words, the OS shouldn’t be able to copy the device’s private key without the user’s consent — though Guillemet also said that using a Ledger does require “a minimal amount of trust.”
