SecurityFirst Approach
Your security is our top priority. Zelcore implements multiple layers of protection to keep your assets safe while giving you complete control over your crypto.
Private Key Ownership
You own and control your private keys. Zelcore never has access to your funds or personal keys. Your keys are encrypted locally on your device.
Decentralized 2FA (d2FA)
Advanced two-factor authentication that doesn't rely on centralized servers or SMS. Blockchain-based security that can't be hacked.
Biometric Login
Secure your wallet with fingerprint or face recognition on mobile devices. Quick access without compromising security.
Device-Level Encryption
Credentials stay on your device, protected by encryption and biometrics. All account processes occur on your device's RAM, which is flushed after closing Zelcore.

What is Decentralized 2FA?
Next-generation authentication that eliminates central points of failure
Traditional 2FA relies on centralized servers and SMS codes that can be intercepted or compromised. Zelcore's decentralized 2FA (d2FA) establishes a user-selected PIN, verified by message signing, that is stored on the blockchain and attached to your account. This creates a truly secure second layer of authentication that cannot be compromised by central authority breaches, SIM swap attacks, or server downtime.
No Central Server
Authentication happens on-chain without centralized control or single point of failure.
No SIM Swapping
Completely immune to SIM swap attacks that compromise SMS-based 2FA systems.
Truly Yours
You control the authentication mechanism completely with your own keys.
