We started with a simple belief: owning cryptocurrency should never mean trusting someone else with your keys.
Fidus Key LLC was founded in San Francisco in 2021 by a small team of security engineers and embedded-systems specialists who had spent years working on authentication hardware, secure elements and consumer electronics. We watched the same story repeat itself too many times: exchanges and online services holding customer funds, and customers losing everything when those services failed.
Our founders believed there was a better way — and that better way was self-custody made simple. In 2022 we shipped the first Fidus Key prototype to a group of early testers, and in early 2023 the Fidus One went on sale to the public. Since then we have grown one customer at a time, driven almost entirely by word of mouth.
To make world-class hardware security accessible to everyone. We believe every crypto holder — from a first-time buyer to a long-term investor — deserves a wallet that is easy to use, honestly priced and genuinely secure. We build our products in small batches, test every unit before it ships, and stand behind them with a two-year warranty and a support team that answers in plain English.
Fidus Key LLC is founded in San Francisco. The first hardware prototype is designed and built in a small workshop in the Mission District.
The Fidus One enters closed beta with 500 testers across 20 countries. Their feedback shapes the final firmware.
Fidus One launches publicly. The Fidus Mini follows six months later as a compact everyday option.
We introduce Fidus Steel, our disaster-proof phrase backup, and expand support to 40+ assets.
Fidus Key ships its 12,000th device and opens our expanded San Francisco support center.
Every design decision starts with the question "does this make the user's keys safer?" If the answer is no, we do not ship it.
We explain exactly what our products do and do not do. No hype, no hidden fees, no lock-in.
Your keys, your coins. We never hold funds, never ask for your recovery phrase, and never will.
"I started Fidus Key because I got tired of watching good people lose money to preventable failures. A hardware wallet should feel like a key to your own front door — simple, reliable, and entirely yours. We have spent five years proving that security does not have to be complicated, and we are just getting started."
