Your crypto, safe in your pocket.

Stasher is a small device — about the size of a thick credit card — that keeps your crypto safe. Think of it like a tiny safe you can carry. Your crypto lives inside the device, not on the internet, so hackers cannot steal it. You use a friendly phone app to see your balances and send money, and press a button on the device whenever you approve a move.

You can, but apps on phones and computers are connected to the internet — which means hackers, viruses, or a stolen phone can steal your crypto. A device like Stasher stays offline, so there is no way for anyone on the internet to reach your money. It's the difference between leaving cash on your desk and locking it in a safe.

Not at all. If you can use a banking app, you can use Stasher. The phone app walks you through every step. To send crypto: you pick what to send, check the details on the device screen, press the button, done. No commands, no code, no complicated words.

Most crypto wallets today rely on math that a powerful new kind of computer — called a quantum computer — will be able to break. Experts say this could happen in the next decade. Stasher uses a new kind of math that stays safe even against those future computers. You don't need to upgrade later. Your crypto is safe now AND years from now.

Anyone who owns crypto and wants it safe. Someone buying their first Bitcoin. Someone saving for retirement. A trader who wants safety without slowing down. A parent setting money aside for their kids' future. If you hold crypto and care about keeping it, Stasher is for you.

Your money is completely safe. When you first set up Stasher, you write down 24 special words (your 'backup phrase'). As long as you keep those 24 words somewhere safe — ideally on paper in a drawer or a safe, not on your computer — you can restore all your crypto onto a new Stasher in minutes.

Ledger and Trezor need to plug into your phone or computer when they approve a transaction — so for a moment, your crypto is close to the internet. Stasher splits this into two devices: one always stays offline with your crypto, another handles the internet. They never mix. Stasher is also built to survive future quantum computers, which Ledger and Trezor are not.

Over 56 popular coins, including Bitcoin, Ethereum, Solana, XRP, Litecoin, Cardano, and Polkadot. We add new ones regularly.

No. We make the device, but your crypto belongs only to you. You are the only one with the password and backup phrase. Nobody at Stasher can access, freeze, or move your money. Even if our company vanished tomorrow, your crypto would still be safe and usable.

Your crypto is still safe. The secret code that controls your money is only on the Stasher device — never on your phone. Your phone is just a screen that helps you use Stasher. A stolen or hacked phone cannot move a single coin, because nothing happens without you pressing the button on the Stasher itself.

You don't have to take our word for it. The code that runs inside Stasher is public — anyone can read it on GitHub and confirm it does exactly what we promise. Independent security experts also check it for us. Nothing is hidden.

A bigger version of Stasher for companies, exchanges, and wealthy families that manage large amounts of crypto. It uses six coordinated devices, team approval rules (for example: 'any three people must agree'), and full audit history so every action is traceable.
