KeyLink: Your Decentralized Key Security Manager​
No internet required, maximum data security guaranteed. KeyLink adopts a decentralized wallet key management protocol to eliminate online attack risks at the source, keeping your digital asset keys in a secure, isolated environment at all times.​
Fully compatible with mainstream NFC standards, it supports offline encrypted storage of key data on NFC tags—a physical safeguard far more reliable than cloud storage. It also offers third-party wallet authorization, allowing you to grant access permissions on demand, balancing convenience and security seamlessly.​
NFC tags need to be purchased by users independently. Recommended models include NTag424, NTag216, NTag215, and NTag213—all verified for compatibility and security through practical testing, helping you build an offline key storage system effortlessly.
