因为本质上二元期权的买卖平价原理就是
buy yes = sell no
sell yes = buy no
Key Findings 如下:
大前提是 Polymarket 用的 CFT (Condition Token Framework) 出來的 YES token 和 NO token 可以剛性 peg 1 USDC(類似於 PT + YT 的概念如果熟悉 @pendle_fi),且 YES 和 NO token 底層是基於 ERC-1155 的不同的代幣。
基於 @cryptogator1121 @poliedge100 的超細節觀察,Polymarket 上 UI 的 Orderbook 會發現下單時雙邊會對稱(你下單 Buy YES 0.65 會發現 Sell NO 0.35 也有一張你的 order),這一開始讓我非常困惑,因為兩個 token 底層是分開的,我一直以為 orderbook 也該完全分開的兩套。
