In the crypto hardware wallet market, clarity of on-device transaction verification and asset recovery after loss are emerging as key selection criteria, beyond the number of supported coins. Cointelegraph compared major wallets by security, connectivity, usability and recovery options. Differences were notable in input experience and screen design. Wireless, wired and QR-based models offer varying trade-offs, but none guarantees safety if users approve malicious transactions or leak backups.

Chinese startup Xteink has unveiled the X4 Pro, an ultra-compact e-reader slightly larger than a credit card and designed to attach to the back of a smartphone.

It supports only non-DRM epub and mobi files and is priced at $99.
