Inspiration

Millions of small merchants conduct business through voice messages and chat, often in languages such as Yoruba, Igbo, Hausa, Efik, and Nigerian Pidgin. Yet most digital payment tools require them to navigate interfaces in English.

We created Hypa Pay to make accepting payments as simple as having a conversation.

What it does

Hypa Pay allows merchants to create, send, and track payment requests using voice, text, or photos in their preferred language.

For example, a merchant can say, "Invoice Ada $50 for two bags," in Yoruba. Hypa's AI interprets the request, prepares a payment draft, and presents the customer, amount, and fees for approval.

Once approved, the system creates a PayPal checkout link. The customer completes payment through PayPal, and Hypa confirms the transaction after receiving a verified webhook.

How we're building it

Hypa Pay combines:

  • Hypa Intelligence: Multilingual speech recognition, translation, and conversational AI.
  • Model Context Protocol (MCP): Payment tools accessible to Hypa's agent and compatible external AI agents.
  • PayPal APIs: Sandbox checkout, order creation, and payment status.
  • Secure backend: Explicit merchant approval, server-side validation, and webhook verification.
  • Hypa Keyboard and Intelligence App: Natural-language payment experiences inside existing merchant workflows.

Challenges

Our main challenges are understanding payment instructions across languages and accents, correctly extracting transaction details, and preventing AI agents from initiating unintended payments.

We address these through structured payment drafts, explicit human approval, and verified payment confirmations.

What we're learning

Building multilingual payments requires more than translating an interface. AI must understand merchant intent, preserve exact financial details, and maintain a clear boundary between AI-generated suggestions and authorized financial actions.

What's next

Following the hackathon, we plan to expand Hypa Pay into a provider-independent payments platform supporting Stripe, Paystack, and other regional payment providers.

Future capabilities include voice-enabled person-to-person transfers, payment management through Hypa Labs APIs, and payment tools accessible to third-party AI agents.

Our vision: Anyone should be able to participate in digital commerce, regardless of the language they speak.

Hypa Pay is submitted

Hypa Pay lets a small business owner run sales by voice, photo or text, in their own language. The Hypa agent writes up the order, the owner approves it, and the customer gets a PayPal link. When the payment clears, Hypa says "paid" out loud.

What we built during the hackathon

  • PayPal Orders v2 in the sandbox: orders, captures, signed webhooks and receipts
  • A merchant approval step, so the agent never takes money without a yes
  • Payment tools for the Hypa agent, plus an MCP server so outside agents can use the same tools
  • Approval and receipts in the Hypa mobile app
  • Hypa Bridge: WhatsApp orders become PayPal links once the owner approves them

Try it: the README has a five-minute quick start, and the app is on TestFlight and Google Play.

Thank you

A big thank you to PayPal for hosting this hackathon and for sandbox tools that made agentic payments easy to build and test. Thanks also to the sponsor partners for the tools and support, and to the organizers and the Devpost team for running such a smooth event and answering our questions along the way.

And thank you to our team, who shipped a lot in a few weeks. We're excited to keep building Hypa Pay for the businesses it was made for.
