From f257457ad3a4520ff8a880dee4b0cbdf8df43fb5 Mon Sep 17 00:00:00 2001 From: WrBug Date: Wed, 7 Jan 2026 00:31:07 +0800 Subject: [PATCH] =?UTF-8?q?feat:=20=E5=AE=9E=E7=8E=B0=20Polymarket=20Maker?= =?UTF-8?q?=20Rebates=20Program=20=E8=B4=B9=E7=8E=87=E6=94=AF=E6=8C=81?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 添加费率查询 API 接口 (getFeeRate) - 修正 API 返回字段名:使用 base_fee 而非 fee_rate_bps(与 TypeScript clob-client 一致) - 在所有订单创建处动态获取费率: * 跟单买入订单 (processBuyTrade) * 跟单卖出订单 (matchSellOrder) * 账户卖出订单 (sellPosition) - 费率获取失败时降级到默认值 "0",确保系统可用性 -
