Speak and Send

"Speak & Send" is a full-stack, serverless application that makes global micropayments as simple as speaking. The Problem: Traditional online payments, especially for tipping creators or in-game purchases, are slow and clunky. They require navigating forms, entering credit card details, and are impossible to use in voice-first environments like VR/AR, smart speakers, or while driving. Our Solution: We built a "voice wallet" with a clean, modern frontend that features a "Hold to Talk" button. A user simply states their command, like "send 5 USDC to @coolstreamer." This triggers a complete AI-driven pipeline, all running on a globally fast Cloudflare Worker: Speech-to-Text: The user's audio is transcribed into text by the ElevenLabs API. Intent Parsing: This text is fed to a Cloudflare AI (Mistral) model, which intelligently parses the human-like phrase into a structured JSON command for the payment. Payment Execution: The system calls the Circle API to execute the payment in USDC on the Arc Testnet, a new L1 blockchain purpose-built for stablecoin finance. Voice Response: The success or error message is sent back to ElevenLabs and played as audio for the user, completing the "voice-in, voice-out" loop. This project is perfect for content creator tipping, in-game/metaverse purchases, and improving financial accessibility. It demonstrates a fast, secure, and incredibly human-friendly financial transaction.
