Satodime

The two-click cryptocurrency storage solution. Secure, simple, tangible. Your uncomplicated entry into the world of cryptocurrency!

Tap the card on your phone, create your first vault, and store your favorite cryptocurrencies. From digital to tangible crypto assets: gift your loaded Satodime card for a unique experience.

Giftable Cold Storage

Your Satodime card supports many cryptocurrencies, including Bitcoin, Litecoin, Ethereum, and ERC20 tokens. You can even store your favorite NFTs. You can create up to 3 different vaults, allowing you to manage multiple private keys simultaneously.

Safe and Secure

Your Satodime is not just a storage device. It contains an EAL6+ certified smart chip that acts as a Secure Element (SE) to carefully manage your (public and private) keys. The private keys are strictly sealed within the secure chip. You will not know the keys until you redeem them. The color of the key slot changes from green to red when unsealed. Transferring cryptocurrencies securely from hand to hand has never been easier, just like a fiat dollar bill.

Manage your balance via your phone

You can use your Satodime card not only with your computer but also with your mobile phone, thanks to NFC technology. Simply tap your card on your phone's reader and interact directly with it. You can then easily create new vaults to securely store your preferred cryptocurrencies.

This is truly secure!

While some providers offer you simple flash memory to secure your private keys, Satodime offers you an EAL6-certified security element: the chip.

And fully Open Source

Because we believe in the free world, we have decided to fully release our code under the AGPLv3 license. From the firmware loaded on your Satodime card to the mobile application you use, everything is open source.
