Charles Guillemet, the CTO of Ledger – a well-known cryptocurrency hardware wallet manufacturer, has warned users about the risks of “blind signing” transactions.

Guillemet defined “blind signing” as “consenting to a transaction to be signed blindly, without understanding what it means.” He also relayed the problems as well as highlighted some of the key issues with blind signing transactions in a recent interview with Cointelegraph today.
