Seed Phrase - what is it and why do I need Seed Storage products?

Seed phrase - what is it?
A seed phrase, also known as a "recovery phrase", is a sequence of 12, 18 or 24 randomly selected words that enables access to a crypto wallet.

Why do I need seed storage products?
Seed storage products are needed to securely and permanently store the seed phrase that enables access to your crypto wallet. These specialised storage solutions protect the seed phrase from physical damage such as fire, water, corrosion and other natural hazards that simple paper would not survive.

Never share your seed phrase
Never share your seed phrase with anyone. Anyone who has access to this phrase can gain unrestricted access to your cryptocurrencies and steal them. Therefore, always keep the seed phrase safe and secret.
