Polymarket 对某些市场收取少量 Taker 费用。费用由协议设定并在撮合时应用 — 你无需在订单中包含费用信息。这些费用资助 Maker 返利计划，每天将费用重新分配给做市商，以激励更深的流动性和更紧的价差。
地缘政治和世界事件市场零费用。 Polymarket 不会对这些市场的交易活动收取费用或从中获利。存入或提取 USDC 也无 Polymarket 费用（尽管 Coinbase 或 MoonPay 等中介机构可能会收取自己的费用）。
费用按市场在撮合时确定。启用费用的市场在市场对象上有
feesEnabled 设置为 true。使用 getClobMarketInfo(conditionID)

费用精度
费用四舍五入到5位小数。收取的最小费用为 0.00001 USDC。任何更小的金额都会四舍五入为零，因此接近极端价格的非常小的交易可能根本不产生费用。
费用处理
费用由协议在撮合时自动计算和应用 — 你无需在订单中包含任何费用信息。SDK 会自动处理所有细节。
要查询特定市场的费用参数，请使用 getClobMarketInfo(conditionID)：
const info = await client.getClobMarketInfo(conditionID);
// info.fd = { r: feeRate, e: exponent, to: takerOnly }
