Direct applicants only, all agency applications are rejected without being processed. About Peyya

We are looking to build our core team of passionate people who are harnessing blockchain technology to build a fair, efficient, safe, and borderless global economy.

Peyya is a next-generation payment provider. We help creators, merchants, and everyday shoppers to pay and get paid hassle-free in any open Metaverse, NFT, or Web3 solution using regular money in ways people already know and trust.

The world around us is rapidly shifting from closed gardens to open, collaborative and fair societies where creators demand ways to own their creations and monetize from their work, and companies express their need to innovate and adapt to meet customer expectations in the emerging metaverse economy. At the same time everyday shoppers are at the sidelines watching with curiosity, just waiting for the next thing to come along that makes metaverse and NFTs accessible for non-crypto natives.

We are building that next thing and our message to the everyday shoppers out there: Attention Shoppers - Metaverse Is Open

Peyya is a technology company that builds a decentralized payments infrastructure to support the next billion everyday people and creators in their strive to engage in the metaverse and the digital creator economy.

Our product is carefully designed to make the shopping experience and payments feel natural in any virtual environment, whether you’re buying an NFT or just grabbing a coffee with a friend. And because we are bridging Web3 with existing payment infrastructure, there’s no need for metaverse residents to go through a lengthy learning curve - anyone can start using Peyya right away. Peyya connects core banking systems with blockchain, digitalizing accounts, and tokenizing balances, enabling the use of central bank-regulated digital money on-chain. It provides the possibility of integration via APIs or via smart contracts. Peyya is a Hybrid CBDC solution meaning we as providers are both issuing the digital currency as well as providing the transaction infrastructure and payment initiation- and account information services.

Our DeFi-as-a-Service platform is working under a European Electronic Money license that enables blockchain projects to open regulated tokenized cash accounts with an IBAN and operate payments with regulated electronic money natively on the blockchain.

What has been built so far?

  • Tokenization and core banking compliance protocols.

  • Global blockchain payment rails - Think of a Swift / Sepa / Bacs / FedNow - Killer

What we are building now

  • Checkout and Buy now buttons for NFTs and Metaverse - Think PayPal for Web3

  • Mobile Wallet - Think Venmo meets Argent

  • Multi-signature Wallet for Merchants and Global companies

  • Embeddable finance 2.0 - Payment gateway embedded directly in NFTs 

  • Product Finance & Buy Now Pay Later - Think Klarna for Web3

  • DeFi-infrastructure-as-a-Service - Think Stripe for Web3
