📌 Why Cypherock Disrupts Cold Storage?
By eradicating the single recovery phrase, Cypherock removes the #1 attack vector in self-custody. Two shards (stored on separate X1 devices) are required to sign transactions, forcing attackers to acquire multiple geographically dispersed targets.

🔍 Key Features:

Decentralized Backups: Split shards between homes, bank vaults, and trusted parties.
Interoperable: Works with MetaMask, Electrum, and Keplr.

⚠️ Critical Considerations:

Losing ≥3 shards forfeits access forever.
Shard distribution requires careful legal documentation.
Higher upfront cost vs. traditional wallets.
