StreamArc

StreamArc is a pay-per-second video streaming platform built on Circle Gateway Nanopayments on ARC Testnet. Viewers deposit USDC once and pay only for the exact seconds they watch, pause and payments stop instantly. Creators earn every second their content is viewed, with payments settling gaslessly via EIP-3009 signatures off-chain through Circle's BatchFacilitatorClient. Built specifically for the ARC ecosystem, StreamArc gives crypto builders a dedicated home for project demos, protocol walkthroughs, tutorials, and community content organized by category and monetized from the first second of attention. Every new user gets a Circle developer-controlled EOA wallet automatically on signup. No seed phrases, no browser extensions, no manual setup. Deposits flow from the Circle wallet into the Gateway contract in one click. Withdrawals settle instantly via BurnIntent funds arrive in seconds. The platform takes a 20% fee on every second watched, split 80% to the creator and 20% to StreamArc. Creators can also receive tips directly via nanopayments, and viewers can bookmark, favourite, follow creators, and leave comments. StreamArc also introduces content ownership transfer, creators can list their video's revenue stream for sale, accept offers from buyers, and transfer full ownership via a three-way nanopayment split: 95% to the seller, 2.5% platform fee, and 2.5% royalty back to the original creator on all future resales. Buyers become the new revenue owner while the original creator retains attribution permanently. Creators can add timestamp markers so viewers jump to exactly what they need and pay only for those seconds. StreamArc is currently live on ARC Testnet and onboarding its first wave of whitelisted creators. The platform is built with Next.js 15, TypeScript, Supabase, Cloudflare Stream, Circle Developer-Controlled Wallets, Circle Gateway Nanopayments, x402 BatchFacilitatorClient, and deployed on Railway.
