Coin World News reports that on June 21, the first day of the Digital Shield exhibition was filled with enthusiasm. The overseas person in charge of DS demonstrated the cold signing interaction completed through QR code scanning and Air Gap methods at the booth, attracting widespread attention. On-site visitors eagerly experienced the EAL6+ level cold wallet signing process and the NFT asset display module. The military-grade security chip equipped in Digital Shield can achieve full offline isolation of private keys, maximizing the security of user assets, which attracted many users to submit their purchase intentions on-site and actively participate in NFT airdrops and lottery activities.
