Rezva

Pay with names
people already know

One resolution layer for every wallet.

Register a phone, QR, email, or wallet name once. Compatible wallets look it up and show where to send the payment — no copied addresses.

01 / How it works

From a familiar name to a payment.

Someone enters a phone, QR, email, or wallet name. Rezva finds the linked destination. The wallet shows the choices and sends the payment.

02 / What you can register

Use what people already know.

Register a phone, email, QR, or a simple wallet name like coffee.rabby. Customers type what they already know. Compatible wallets look up where to send the money.

Payment QR codes

Same sticker. Crypto wallets too.

Many countries already use one QR for banks and apps. You can register that same QR with Rezva so crypto wallets can pay it too — without a new sticker for every wallet.

03 / Built for wallets

Add lookup. Keep everything else.

Your wallet still scans, builds, signs, and sends. Rezva only answers: where should this payment go?

Scoped access

Add name and QR lookup to the send screen you already have. You still build and sign payments yourself.

04 / Who uses it

Wallets, shops, and wallet names.

Shops register what people already use. Wallets look it up. Wallet apps can also offer short names under their own brand — like shop.rabby — so users pay with a name they trust.

W

Wallets

Look up a name or QR, then pay with the wallet you already use.

S

Shops & creators

Register once. Get paid from any compatible wallet.

@

Wallet names

Namespaces let a wallet offer names ending in its brand, such as alice.rabby.

06 / Before you pay

See who you are paying.

Instead of pasting a long address, you look up a name people already use. Your wallet shows the shop, how they accept money, and where it goes — then you confirm.
