Gas price index on a 7-day cycle

 - 钱包页：每个钱包可以改名（留空恢复默认，最长 16 字），名字在终端和 PLEDGER 上都用；非主钱包可以销毁（点两次确认，钱包里还有币时不让销毁）。钱包编号固定，销毁别的钱包后名字不会错位。
 - 游戏内验证（这一轮）：复制钱包 3 地址后在主钱包发送页粘贴，地址正确；选中 CRT 行高亮，进发送页默认 CRT；向钱包 3 转 1 CRT 后点销毁被拦下；钱包 2 二次确认后销毁，钱包 3 仍叫"钱包 3"；钱包 2 改名为 cold，终端与 PLEDGER 都显示新名字；三列余额对齐。PLEDGER 上名字被标题样式转成大写，已改成普通粗体（编译通过，没重进游戏看）。没有验证：游戏输入框里直接 Ctrl+V。
 - 转账手续费档位（核对页选 慢 / 普通 / 快）：0.5 / 1.5 / 4 信用点等值，用转出的币扣（DEX 签名用付出的币）；需要的确认数随金额：3 次，≥ 2000 时 6 次，≥ 10000 时 12 次，动画随之变长。
+- Gas 价格指数：7 天一个周期正弦涨跌（0.5×–1.5×），每天再乘 1 ± 15% 随机波动，夜间结算算出第二天的值；手续费 = 档位基础价 × gas（拥堵时再 ×4），核对页显示"Gas ×n"。游戏内验证：过一夜 gas ×1.34，普通档手续费 1.5 → 2.01 信用点。
 - 网络拥堵：每晚 12% 开始，持续 1–2 天，上报纸；拥堵时手续费 ×4，普通档确认 ×2 慢、慢档 ×3.5 慢，慢档 30% 被挤出内存池（未成交，手续费照扣，账单留着可以重付）。PLEDGER 主页和核对页显示"网络拥堵"。
 - 地址投毒：每笔转给外部地址的转账有 35% 被盯上，1–2 天后钱包收到一笔来自相似地址的 0 币转入（前 3 位和末 2 位校验位一样，缩写完全相同）。PLEDGER 发送页新增"最近"列表（← 转入 / → 转出，缩写地址），点一下填入地址，投毒地址混在里面；核对页对有往来的地址显示"有往来记录"，投毒地址也会显示。
 - 剪贴板木马：被投毒的钱包上点"粘贴"，30% 把地址换成相似地址（和一次转空并存）。

The higher the multiplier, the slower the sale (below 0.9x about a day, 1.0x about two, 1.8x about fourteen), and the likelier and larger the taint on the payout, which also grows with how much you sold in the last 7 days; at most 10 listings at a time, 5% listing fee, repricing a listing costs 2% and the sale speed follows the new multiplier, 8% commission, payout held 3 days before reaching your wallet; a fake card may be spotted and returned, hurting your rating; if the platform rugs, listed goods and unreleased payouts are gone.
