About Lenz

Lenz brings private conversations and offline financial agreements together. This build uses tUSD test tokens with no cash value.

Your identity and encrypted history stay in this browser. Clearing its storage loses them.

What this prototype establishes

Chat uses signed, encrypted packets and separate browser identities. File and paste handover are available; automatic Bluetooth and mesh delivery are not connected. Once cached, the page and cryptographic operations can run without its server.

Contact QR cards contain public keys. Names and initials are labels, not proof of identity. Get a card directly from its owner or confirm it through a trusted channel. Full fingerprints remain available under technical details. Camera images are processed on this device.

Packet routing identities, lengths and timing are visible. Message history is stored as ciphertext. This construction has no forward secrecy and does not protect an unlocked or compromised browser.

The tUSD wallet starts at zero and settles funded test payments on NEAR; Rhea swaps also have testnet evidence. Zcash has a separate native shielded test flow and unsigned browser review, without browser signing. Hidden conflicts, unresolved offers, private NEAR settlement and safe recovery remain open. Test tokens have no cash value, and offline acceptance does not guarantee redemption.
