Why ZePay Exists

Most people never touch crypto because the UX is painful: install a wallet, store a seed phrase, buy gas, accept endless pop‑ups, and learn strange new words just to move money. Web2 apps win because they are simple – email and password, clean screens, one‑tap actions.

But Web2 has a cost: your balances live in their database. You are always trusting a third party not to freeze, mismanage or lose your money.

Zepay was created to prove something specific:

Vision

Blockchain technology has matured to the point where you can completely hide the chain and build an app that feels like Web2 – fast, zero‑fee, no wallet popups – without giving up self‑custody.

For the first time, Zepay gives you all three together:

• Web2 convenience – sign in with email, no wallet setup, no seed phrase, no gas onboarding, no transaction pop‑ups.

• On‑chain self‑custody – funds live in your SmartAccount and PersonalVault on Sonic, controlled by your own EOA key.

• A small taste of DeFi yield – your USDC can earn yield in the background via Aave, with transparent accounting.

Zepay exists to show that you do not have to choose between UX and self‑custody anymore.

Why Sonic makes this possible

Zepay’s model only works on a chain with the right base properties. Sonic provides:

• Fast blocks and instant finality – transactions settle in sub‑seconds.

• Low, predictable gas fees – the relayer can realistically pay gas for users.

• Feem economics (90% to ecosystem) – the fee system is designed so that apps like Zepay can sustainably subsidise gas and abstract the chain.

Without Sonic’s combination of throughput, finality and Feem, a gasless, walletless, self‑custodial UX at scale would either be too slow or too expensive.

Zepay is a live demonstration that with the right L1, you can build an app that feels like Web2, while the money lives fully on‑chain.
