Crypto, crypto, crypto… Over the last couple of years, this word has proliferated and now founds itself a staple in our everyday lexicon. However, CryptoCurrency is not a new invention, it’s been around since 2009 when Bitcoin, the first decentralized cryptocurrency was created. Once esoteric knowledge, bitcoin, and cryptocurrency have been growing steadily in popularity, only to burst into the mainstream in the early 2020s.

With crypto and other digital assets comes a very real and dangerous problem…cyber attacks. These threats pose a huge problem within the digital space. It’s not uncommon to see a headline stating “100 Million Dollars Stolen in Crypto” or “NFT Rug Pull Costs Millions in Losses”.

With these growing concerns on cyber security, one E-Switch customer is doing all they can to keep us, regular investors, safe as we traverse the metaphorical wild-west of this digital realm. Their crypto wallet comprises of a physical hardware wallet and a live application. The pairing of hard and software adds a whole new layer of security. The hardware wallet resembles a USB stick and acts as the key to opening your account. Without this physical key, one cannot access the account thus protecting you and your hard-earned digital assets.

Now, how does one control this crypto wallet, with TL4110 Tact Switch from E-Switch of course!
