// Launch a market
registerMarket(baseToken, feeRecipient, metadataURI)
// metadataURI = "data:application/json," + encodeURIComponent(JSON.stringify({
//   name, symbol, description, iconUrl, bannerUrl, audience, role }))

// Post a sell offer: approve the token, then
createFundedOrder({ marketId, maker, quoteToken: 0x0, baseAmount,
  quoteAmount, expiry, salt, side: 0, escrow: true })

// Take it: ask for the exact quote, send it as value
q = quoteFill(order, amount, taker)
fillOrder(order, amount, q.buyerTotal, 0, "0x") { value: q.buyerTotal }

// Cancel (maker only, works while paused)
cancelOrder(order, refundTo)

Open offers are enumerable on chain with fundedOrderCount(marketId) and getFundedOrder(marketId, i); check filledBase and cancelled by order hash.
