Siftle

Siftle sells football news one insight at a time. The TypeScript app pairs live story threads with locked AI briefings that unlock through sub-500ms x402 USDC nanopayments, wired with @circle-fin/x402-batching — a seller middleware in scripts/serve.mjs and a GatewayClient buyer flow in scripts/x402-local-pay.mjs exercise Circle Gateway end to end. Circle wallet onboarding runs through @circle-fin/w3s-pw-web-sdk. A Foundry suite adds gamified prediction markets: contracts/src/SiftleMarket.sol handles USDC share buying, resolution, and payout claims, while contracts/src/SiftleMarketFactory.sol spins up new markets, deployed to Arc via contracts/script/DeployArcTestnet.s.sol. An operator/resolver rules engine in scripts/marketThreadRules.mjs automates market resolution and settlement, and a Node backend in scripts/serve.mjs ties feeds, briefings, and markets together over a Supabase schema.
