Digital vaults are only as strong as their code. Seed phrases get exposed. Access gets silently hijacked. When your security lives entirely on a screen, it is vulnerable.
The Material Solution
EtheLock introduces a tangible barrier. We bridge the gap between cold storage security and hot wallet speed. Your assets remain frozen until you physically tap. Without the card, the digital world cannot touch you.
Features
Your Wallet, Reimagined
Ephemeral Identity
We don't store keys. We create them. Every time you tap, a fresh cryptographic identity is generated for that specific session. When you are done, it vanishes.
Two-Factor Physics
Something you know (PIN) plus something you hold (Card). Combined, they create an impenetrable fortress. Separated, they are useless to thieves.
The End of Seed Phrases
Forget panic-inducing 24-word backups. Your wallet is deterministically derived from your physical card and your unique PIN. You are the recovery phrase.
Auto-Lock Protocol
Walk away with confidence. The system detects inactivity and severs the connection after 15 minutes. Security that never sleeps, even when you do.

FAQ
Frequently Asked Questions
What is EtheLock?
EtheLock is the physical gateway to the Ethereum ecosystem. It transforms any standard NFC card into a hardware key, requiring physical verification for every transaction.
How does the tap work?
Tap your card against your phone and enter your PIN. That is it. The app derives your wallet access instantly. No passwords to remember, no complex hardware to charge.
Is it safe?
It is military-grade. Private keys are never stored on any server or device. They are generated on-demand and destroyed upon session closure. Without your physical card and your PIN, your wallet effectively does not exist.
What if I lose my card?
You remain in control. You can create an encrypted backup file stored securely in the cloud. If your card is lost, use the backup to access your funds and migrate them to a new wallet linked to a new card.
Which chains are supported?
EtheLock is native to Ethereum. You can manage ETH, USDT, USDC, and the entire ecosystem of ERC-20 tokens.
