OPOLO FAQs

Q. Why is OPOLO Cosmos Secure?

A. There are several reasons why OPOLO Cosmos can be considered the most secure wallet. Here are some of them:

  1. OPOLO Cosmos uses a Secure Element (SE) that has CC EAL6+ certification and was developed by one of the major semiconductor companies, NXP.
  2. The mnemonics or private key, any data that is sensitive, never leaves the OPOLO Cosmos device.
  3. The passphrase is never stored on the device.
  4. The password is not stored anywhere except in the Secure Element.
  5. The wallet mnemonics are never stored anywhere except in the Secure Element when the device is powered off.
  6. The password and passphrase are entered directly onto the device to avoid the chances of viruses sniffing the data from a computer.
  7. The password size could be as long as 120 characters long, not supported by any other wallet in the market.
  8. The passphrase can be as long as 120 characters long to give users ultimate security, which is not supported by any other wallet in the market.

Q. How can I check if my OPOLO Cosmos device is genuine or not?

A. In OPOLO Cosmos SE, OPOLO stores a unique private key (generated and installed from an air-gapped computer) used for genuine validation. This private key can only be used to sign random data. You can check the authenticity of your device from the Settings page of OPOLO Desk or OPOLO Mobile app.

Q. How does OPOLO Cosmos generate a wallet? Does OPOLO Cosmos support BIP-39 standard?

A. OPOLO Cosmos has an STM32F4 microcontroller that randomly generates the seed for a wallet. From this seed, mnemonics are generated following the BIP-39 standard. The wallet, generated by OPOLO Cosmos, is fully compatible with other BIP-39 wallets. The users may add a passphrase (up to 120 characters) of their own choice to the BIP-39 wallet. For more info on BIP-39, watch this video explains BIP-39.
