Zeyphr is a decentralized Web3 marketplace and crypto-native payment platform built using the IOTA EVM. It enables users and businesses to transact seamlessly, both online and offline, with familiar Web2-like user experiences—email logins, one-tap payments, QR scan, and more—while abstracting away the blockchain complexities underneath.

After our May 4th submission, the IOTA EVM Faucet we used was deprecated. Since our “Bank Deposit” feature wasn’t ready before the deadline, we relied on the faucet to fund wallets.

To ensure a smooth demo, we allocated 4500 IOTA to a central wallet. New users now receive 100 IOTA on signup to try key features like scan & pay, transfers, and purchases.

You can watch our demo video and compare it with the current app — you won’t notice any critical new features.

If you have any questions, please feel free to email us at [email protected]. We’re happy to help and usually respond within 14 hours.
