2. no one can ever see how much you're paying
3. unlimited transactions, unlimited amounts
payy fam, weโre cooking up an amazing fiat ramp experience for you. no bridging or wrapping ever again. itโs all automated and integrated into the app. hereโs an early design for the deposit screen.
if youโd like to get early access (limited spots), fill out this short form:
I canโt keep it in any longer. Iโm spilling the beans on our mega launch at ETH Denver.

@audit_wizard
for cohosting with us.
payy is in beta, here's what that means
1. smart contracts and zk circuits have been audited
2. there may be UI issues in the app
3. we are still experimenting with the rewards system (but points will be saved across experiments)
4. we are still improving decentralization
what happens when you send money on payy?
- UTXO zk proof generated on-device for the right amount
- proof & update hash sent to Payy Network
- encrypted txn data sent to registry
- ephemeral wallet + pk embedded in link
- you send link via imessage/whatsapp
what if sending money was as easy as sending a message? to anyone, in any country. instantly. privately. for free.
sound impossible?
itโs possible with
@payy_link
. an app that lets you pay anyone in the world, instantly and privately, for free.
1. venmo is US-only โ try payy
how do payy links work?
when you send money to someone, the payy app generates a link. treat this link like cash. anyone with the link can redeem the payment to their wallet. do not post payment links in groups or publicly. you can cancel links that have not been redeemed yet,
just announced: google pay app is being shut down
- no peer to peer payments after june 4, 2024
- payments to india & singapore disabled
- only affects u.s. accounts
combine this with paytm shutting down in 2 weeks
guess what app i recommend switching to?
how does payy integrate with other chains?
payy is designed to be chain agnostic, but right now we use Polygon as a settlement layer cheap on-chain verification and easy bridging

Simple crypto bank,
Venmo plus DeFi, private
Improve lives, billions.
One wallet for all,
Chains, gas, signing, all hidden
Crypto, yet feels safe.
why are there no login, email or passwords in the payy app?
username/email/phone numbers are used used to track you. we believe in the privacy of your financial transactions.
to send money, you send payment links using whatsapp, signal, imessage, email, etc.
what happens when you deposit funds into payy from an exchange?
- payy wallet generates polygon deposit address
- exchange sends USDC to address
- tokens are forwarded from that address to payy L2 bridge
- USDC is wrapped and sent to users payy wallet
similar with any fiat ramp
it's here: Payy Network Explorer v1

when you send a txn in payy, what happens?
- app makes a new utxo note with unspent balance (and a zk proof)
- proof and hash are sent to the payy network (zk rollup)
- the rollup sends a block to the rollup chain (currently Polygon)
- zkp is verified by our rollup contract
so how does payy work?
payy stores your funds on the polybase zk-for-privacy-rollup and allows you to send and receive money from people using qr codes and links. your payy wallet is secured by cryptographic keys that are backed up on your phone.
you can deposit money into payy
