In this episode of the Efani Features Podcast, host Mark Kreitzman welcomes Rohan Agarwal, co-founder and CEO of Cypherock, for an in-depth conversation on one of the most innovative hardware wallets in the crypto space: the Cypherock X1.

Rohan shares the origin story of Cypherock, sparked by personal loss of funds during the 2018 crypto downturn. That experience led to a bold mission — to build the world’s safest and most user-friendly hardware wallet, solving the two biggest problems in self-custody: single points of failure and lack of inheritance solutions.

🔐 In this episode, you'll learn:

• How Cypherock decentralizes your private keys across 5 tamper-resistant devices — eliminating the risk of losing everything if a single device or seed phrase is compromised
• Why the Cypherock X1 is 10x more secure than traditional hardware wallets like Ledger or Tangem
• How it enables secure, non-custodial inheritance of your crypto — without giving up privacy or handing out your seed phrase
• Why users in the U.S., Canada, and Europe are increasingly choosing Cypherock for cold storage
• How it’s fully non-custodial, doesn’t require an internet connection, and works even if Cypherock disappears

You’ll also hear comparisons with other wallets, learn about Cypherock’s cryptographic threshold schemes, and find out why this wallet is trusted by security experts and rated highest by CoinBureau.

Whether you're new to cold storage or ready to level up from your current hardware wallet, Cypherock offers a compelling blend of usability and high-assurance protection — all with global shipping and support.
