Average house fires exceed temperatures of 1000°F
Is your seed phrase safe?
House fires
The average house fire burns above 1,000F (source), paper wallets, traditional hardware wallets made of plastic and silicon chips, cell phones, laptops – nearly all electronic devices will be destroyed in a matter of minutes. With the destruction of these devices comes the potential loss of your crypto holdings.
We sincerely hope you will never experience a fire – fires are a terrifyingly common occurrence, with 374,300 residential fires in 2022 (in the US), according to the U.S. Fire Administration (source).
