PERSTREAM

@Donyemiight·added 2026-07-19

PERSTREAM is a per-second USDC streaming paywall for podcasts and long-form audio. Press play and payment ticks every second; pause and it stops. The settlement engine in backend/src/meter.js runs a one-second tick loop per listening session, recording totals in SQLite via backend/src/db.js. backend/src/arc.js implements two payment modes: an in-memory demo ledger, and a live path using the GatewayClient from @circle-fin/x402-batching to sign EIP-3009 TransferWithAuthorization ticks for batched USDC settlement on Arc testnet, with contracts/PerStreamPaymaster.sol on the chain side. The frontend ships listener and creator surfaces (frontend/listen.html, frontend/creator.html) with email-based embedded wallets, and backend/src/agent-listener.js demonstrates an autonomous agent streaming on a user's behalf.
