Highest Rated Secure Element
The security of an integrated circuit depends on the EAL certification. This can range from 1 to 7. The higher the EAL number is, the greater the security. Most hardware wallets do not use secure elements at all. Some use EAL 5 or less. The OPOLO Cosmos uses an EAL 6+ secure element. This is more secure than the best known hardware wallets and is the highest EAL rating of any hardware wallet on the market.
