Lepta
Lepta meters livestream payments by the second. Its proof-of-flow scheme hashes and timestamps each HLS segment from an Owncast server in src/lib/attestor.ts, matches server attestations against viewer heartbeats every second in src/lib/meter.ts, and accrues USDC only while delivery is verified — stalls pause the meter. A budget agent in src/lib/agent.ts (Claude Haiku via LangChain, with a rule-based fallback) reviews spend, engagement, and watch time to continue, pause, or request top-ups, with its reasoning shown live in the viewer UI. Accrued amounts batch on-chain through Circle Gateway via src/lib/settlement.ts and src/lib/circle. The Next.js app pairs a custom server.ts with Socket.io for real-time meter ticks and a creator dashboard.
