# Payy

> Bank Onchain.

Payy is a stablecoin payments company offering a self-custodial wallet, card, and privacy-focused blockchain network. It lets individuals and businesses hold, send, and spend stablecoins privately.

Payy is a stablecoin payments company that builds self-custodial wallet, card, and blockchain infrastructure for private stablecoin transactions. It offers a non-custodial mobile wallet, a spending card, and an Ethereum layer 2 network designed around privacy, along with developer tools for integrating private transfers. The products serve individuals, businesses, and platforms that want to move and spend stablecoins without exposing balances or counterparties.

The company addresses the exposure created by public-by-default blockchains, where balances and counterparties are visible to anyone. Payy uses zero-knowledge proofs to verify and settle transactions without broadcasting transaction details, while private keys remain on the user's device. Its network is an Ethereum-compatible rollup with familiar account and contract patterns, adding a native privacy layer for transfers and payments.

Payy Wallet lets users hold, send, and receive stablecoins, including through shareable payment links, while Payy Card converts wallet balances into everyday purchases. Payy Client, a software development kit, gives developers access to the network's privacy bridge, transfer signing, and proof generation for building custom applications. The offering is used by consumers, businesses, and platforms seeking private, self-custodial stablecoin payments across multiple countries.

## Products

- [Payy Network](https://thegrid.id/profiles/payy): Payy Network is a Layer 2 rollup that settles to Ethereum and provides the transaction, privacy, and settlement layer for Payy's stablecoin products. It processes private transfers off-chain using zero-knowledge proofs and a validator-run node client, then anchors state to Ethereum smart contracts for finality. Wallets, cards, and other client applications connect to it through RPC endpoints to move and settle stablecoin balances without exposing balances or payment history publicly. (L2, Live)
- [Payy Wallet](https://thegrid.id/profiles/payy): Payy Wallet is a self-custodial mobile app for holding, sending, receiving, and spending stablecoins without managing chains, addresses, or transaction details directly. It generates keys on the user's device, moves value over Payy Network for private, low-cost transfers, and lets users create claimable payment links that recipients redeem through everyday messaging apps instead of copying wallet addresses. Public balances and payment history are not exposed, and users can fund the wallet from crypto exchanges or other wallets. The app underlies Payy's card product, letting verified users extend their stablecoin balance to everyday spending. (Wallet, Live, Main Product)
- [Payy Card](https://thegrid.id/profiles/payy): Payy Card is a self-custodial payment card that lets verified Payy Wallet users spend their stablecoin balance through the Visa network. Spending routes through Payy Network so onchain balances and payment history are not exposed to merchants or the public ledger. Users can activate a virtual card for online purchases and add it to mobile wallets, or request a physical card for in-person spending, with the ability to freeze or unfreeze it from the app. (Card, Live)
- [Payy Client](https://thegrid.id/profiles/payy): Payy Client is a developer SDK that lets external applications integrate with Payy Network for private stablecoin transfers and transaction handling. It exposes the interfaces needed to build private transfers, construct Payy transactions, and interact with predeployed system contracts on the network. Wallets, exchanges, and fintech applications use it to add Payy-based stablecoin functionality without building the underlying privacy and settlement logic themselves. (Developer Tooling, Live)

## Assets

- [Payy (PAYY)](https://thegrid.id/profiles/payy): PAYY is the value-accrual token of Payy Network, a privacy-focused stablecoin payments rollup. It is intended to capture network revenue and align incentives among the protocol's participants once distributed. The tokenomics documentation describes a future pre-sale and token generation event, indicating the token has not yet launched. (Governance)
- [Payy USD (PUSD)](https://thegrid.id/profiles/payy): PUSD is a USD-pegged, treasury-backed stablecoin native to Payy Network. It is designed to serve as the network's native gas token, used for private transfers, wallet payments, and network activity without requiring users to hold a volatile asset for fees. The tokenomics page uses future tense to describe PUSD, and predeployed contracts documentation lists it as a native ERC-20 view rather than a standard deployed token contract. (Stablecoin)
