Empowering Developers through Collaboration at the First Global PYUSD Portal Hackathon

Initially, we will examine the concentrate of the hackathon, which is PayPal USD (PYUSD). PYUSD is a stablecoin that is entirely backed by the US dollar and is open for use in payments. PYUSD provides developers with a rapid and cost-effective solution for developing decentralized payment applications, as it is deployed on Solana. Solana’s ecosystem is optimal for integrating PYUSD into Web3 and PayPal/Venmo wallets, as it offers minimal fees and high transaction velocities, facilitating seamless transfers between various systems.

Developers were tasked with developing viable projects that capitalized on the potential of PYUSD, addressed real-world obstacles, and paved the way for the future of decentralized digital payments. Blockchain and stablecoins provide streamlined, affordable, and rapid solutions that will improve the accessibility of global transactions, thereby transforming cross-border payments.

Ripe, a blockchain-based payments platform, developed the Universal QR Scanner SDK to resolve these issues and to enable cost-effective, straightforward cross-border payments via PYUSD. Developers can effortlessly create applications that enable users to scan the QR code of a supported crypto wallet or Solana Pay request, select a payment amount and currency, and finalize the transaction with PYUSD using the Ripe SDK. The SDK is compatible with various QR code formats, including Solana Pay, crypto addresses, and prominent fiat e-wallets in Southeast Asia, including GCash, GrabPay, PayNow, and SGQR. The SDK enables recipients to receive funds in their local fiat currency even though the payment is made with the convenience of PYUSD.

Users can conveniently examine and verify their transactions by utilizing Solana Pay QR codes, which include embedded transaction details. To ensure precise recordkeeping, the SDK encrypts supplementary data, including currency and denomination, in the memo field for fiat transactions. A confirmation screen that displays the transaction details and a tracking feature that allows users to assess past transactions are also beneficial. Ripe’s solution enhances the accessibility of digital transactions, particularly in Southeast Asia, where customers prioritize QR codes and e-wallets over traditional banks and credit cards, which are heavily reliant on remittances.
