A Solo is a metallic bar on which we engrave secret keys that unlock crypto-asset units. A security hologram covers each code. Currently Bitcoin and Ethereum are supported.
You buy it; you hodl it.
There is no need to install software or open an online account.
You can have the Solo Steel, Solo Silver or Solo Gold.
The private key is computed only during the redeeming process. The companies involved in the engraving process never have access to the full private key.
All the information on the Solo is engraved which means no electronic part sensitive to hardware failure and no battery issues. The Solo is robust and designed to last. Perfect for preserving your wealth.
The patent application describes our process to inscribe cryptographic codes on a physical support in such a way that nobody has ever had access to the full private key.
