@RockNBlockX Кайф, спасибо!

Прикольное техническое объяснение (ссылка ниже), как устроен торговый стакан в Polymarket. Там довольно остроумный механизм: каждый лимитный ордер на покупку Yes за условные $0,65 автоматически зеркалируется в лимитный ордер на продажу No за $0,35 (так как сумма вероятностей Yes + No любого события должная быть равна единице). В результате, новые "акции" для торговли выпускаются автоматически, когда нашлась подходящая пара покупателей на эти зеркальные цены. В нашем примере — одновременно кто-то заплатил $0,65 за покупку Yes и $0,35 за покупку No. Итого на рынке появилась суммарно как бы одна новая акция события и в смарт-контракте заблокировался один доллар, ее обеспечивающий.

Gasless UX works when the underlying contracts are secure. Happy to complete the audit with @zokyo_io for our work on @MezoNetwork and the GasStationExecutor contract. Appreciate the team’s responsiveness and smooth collaboration throughout the process.

@zokyo_io @MezoNetwork 🤝

Audit Complete 🔒 We're excited to announce that @RockNBlockX has successfully completed its security audit with Zokyo for smart contracts developed for @MezoNetwork. Rock'n'Block is a Web3-native development studio with 8+ years of blockchain expertise, powering products used by over 70 million users globally. For this engagement, Rock'n'Block developed the GasStationExecutor contract for Mezo — a Bitcoin-first economic layer that enables users to borrow, earn yield, and transact using BTC without ever selling it. The audited contract enables gasless token swaps on EVM-compatible chains, leveraging EIP-712 signatures and a relayer architecture to allow users to execute swaps without needing to hold native gas tokens. With this audit, Rock'n'Block and Mezo reinforce the security of the infrastructure powering gasless transactions within the Mezo ecosystem.

Polymarket 学习笔记 Polymarket 是一个用于交易现实世界事件结果的预测市场协议，事件被构建为具有「是或否」结果的二元问题，用户购买代表其对结果信念的份额。 每个事件都有 Yes 和 No 两种份额，价格在 0～1美金之间，总和为1美金，价格反应了市场对结果发生概率的预期，当事件结果揭晓时，正确结果的份额结算为1，错误的结算为0，交易者可以持有份额至结算，也可以中途退出。 Polymarket 采用中央限价定单薄 CLOB，且为混合去中心化模式，订单链下匹配链上执行，每个事件有一个统一的订单薄，会显示为两个结果相反的镜像订单。 定单薄为二元期权交易构建，提交现价单时，系统会同步显示对应相反结果的镜像。 市场价格基于供需关系确定，用户发布买卖订单，价格便在互动中形成。当一个新的市场被创建，最初的定价出现在交易者发布限价订单时。 Polymarket 订单执行方式：匹配，铸造，合并。 匹配：买卖双方直接交换，没有新的份额被创建或者销毁。 铸造：非用户之间直接交易，双边市场同时买入，当相反结果的订单价格匹配时，新的份额被创建。 合并：非用户之间直接交易，双边市场同时卖出，当相反的卖出订单匹配时，现有份额将被销毁。 由于某一时刻的供需可能不是平衡的，大额订单可能会被拆分搁置，小额订单全部成交。 事件结果确认：UMA 乐观预言机负责上传事件结果，任何用户都可以通过质押保证金提交结果，若2小时内没有异议则结果成立，争议结果会触发 UMA 代币持有者投票。
