Today’s content economy forces users into full monthly subscriptions even when they only want one specific article, one creator update, or a few minutes of video. This creates waste on both sides: users overpay for unused access, and creators depend on rigid bundle models that hide true engagement value. Sava is built to solve exactly that. Sava is a pay-as-you-consume platform where users unlock content progressively instead of buying all-or-nothing plans. If a user reads only part of an article or browses a few pages of a PDF, they are charged in tiny increments based on real usage. That removes subscription friction and makes pricing feel fair, predictable, and aligned with intent. Under the hood, Sava uses USDC nano-payments on ARC blockchain. On first login, each user gets a Circle developer-controlled SCA wallet. Users top up once, then consume content normally while the backend handles automated micro-charging in the background. When wallet balance is available, it can auto-deposit into gateway balance for smoother payment flow. As users scroll/read/watch, backend metering tracks progress and triggers x402-compatible payment calls, signing with Circle wallets (including delegate-based signing when enabled). Every attempt is logged with full metadata for transparency: typed data, signatures, payment payloads, settlement responses, and status. Creators benefit because revenue maps to real interaction, not just subscription churn. Users benefit because they pay only for what they actually consume no forced monthly plans, no paying for 90% unused content. Sava turns content payments from “commit first, maybe use later” into “use first, pay fairly as you go.”

In this hybrid hackathon powered by Arc and Circle, developers will build the next generation of Agentic economic applications using Circle’s Nanopayments infrastructure with settlement on Arc in USDC. For the first time, high-frequency, usage-based transactions between users, APIs, and AI agents can operate without gas overhead eroding margin. Arc provides stablecoin-native settlement with predictable, dollar-denominated USDC fees and deterministic, sub-second finality — enabling real-time coordination and economically viable per-action pricing at scale. 📅 April 20 – 26, 2026 • Apr 20 – 25 (Online): Submit projects by Apr 25. • Apr 25 (On-site Build – SF, CA): Teams refine projects. • Apr 26 (On-site Demos & Awards – SF, CA): Live pitches & winners announced.
