Hot wallet versus Kald cold storage

Hot wallet

Software wallets stay online. Keys sit where the internet can reach them.

  • Always online, exposed to attacks
  • Third-party custody risk
  • Vulnerable to malware and phishing
  • Cloud-connected and breachable

Kald

Hardware cold storage. Keys stay offline and under your control.

  • Fully offline signing
  • Immune to remote hacking
  • Complete self-custody
  • Air-gapped, physically isolated

$3.8 billion was stolen from crypto exchanges and hot wallets in 2022. With Kald, your keys stay offline and under your control.
