Building decentralized prediction market infrastructure.

Not on mainnet. No real funds at stake. Not audited.

Non-custodial

Somust never holds user funds. USDC is escrowed only inside the market contracts; users sign every action from their own wallet, and winners claim directly on-chain.

UMA oracle

Markets settle through UMA's Optimistic Oracle V3 — an on-chain assertion with a public dispute window, not a closed admin call.

Polygon

Built for Polygon for low fees and high throughput. Target deployment is the Amoy testnet while the contracts move toward a mainnet release.

Build on open data.

Interroge les marchés agrégés, récupère l'historique de prix et lis un carnet d'ordres live. L'API publique est gratuite, sans clé, et renvoie du JSON.

// Public market data — no API key, open CORS
const base = 'https://somustmarkets.com/api/markets';

// Market detail (question, prob, volumes, rules)
const detail = await fetch(
  `${base}?mode=detail&source=polymarket&slug=<slug>`
).then(r => r.json());

console.log(detail.question, detail.prob);

// Live order book + recent trades
const book = await fetch(
  `${base}?mode=book&source=polymarket` +
  `&key=${detail.historyKey}&cond=${detail.conditionId}`
).then(r => r.json());

console.log(book.book.bestBid, book.book.bestAsk);
