GMX is a decentralised perpetual and spot exchange that allows you to trade assets on-chain, without an account, KYC, geographic restrictions or high centralised exchange fees.

Web3赌场，庞氏代表之作

特点：使用Chainlink预言机，0滑点；高杠杆；DEX自带的公开透明属性；无XYC

代币模式：双币系统---$GMX; $GLP

Traders on the GMX platform on the Arbitrum network can perform asset swaps on ETH, BTC, LINK and UNI and a variety of stable coins. And traders on the Avalanche network can perform asset swaps on ETH, BTC and AVAX and a variety of stable coins.

The GLP pool is essentially a liquidity pool that acts as the counterparty to traders on the GMX exchange. This means that if traders on GMX make a profit, GLP holders make a loss and vice versa.

盈利模式：

The GMX protocol generates revenue by charging fees on the opening and closing of trades and also a “borrow fee” that is deducted every hour a leveraged position is open.

The Fees generated by the exchange are distributed entirely back to GMX and GLP holders. 70% of these platform fees will be distributed to GLP holders and 30% of them will distributed to staked GMX holders. Staked GMX holders receive 30% of the fees generated from both Arbitrum and Avalanche exchange.

However, since the GLP token is unique on each of these networks, holders of the Arbitrum GLP token will receive 70% of the GMX (Arbitrum) platform fees in ETH and holders of the Avalanche GLP token will receive 70% of the GMX (Avalanche) platform fees in AVAX.

Below are some relevant risks GMX has to take into account:

Liquidity risks. As stated, the GLP pool is the counterparty to traders. If profit traders » profit liquidity providers, the GLP pool could get drained and suffer low liquidity, so the protocol should allow more yield to be attractive for LPs. Often, more yield means more token inflation at the end, even though the GMX token mechanism leads to controlled inflation.

Market manipulation. The token is highly volatile, and the price action looks like a spiky chart. To make an example, on September 22, a DeFi trader manipulated $AVAX by taking advantage of the difference in the slippage between GMX and CEXs. Although GMX worked “as designed,” the team decided to cap at $2M AVAX open interest on their exchange.

Centralization risk. Per the current configuration, the keepers — some team members who choose assets’ price GMX — have some degree to charge an extra invisible price to the user. A poor initiative only sets a spread if the keeper’s price deviates from the Chainlink price by more than 2.5%. This means that a keeper can charge up to such spread value. And this would only make the price worse for the traders (non-value-aligned).

Scalability risk. For the GMX growth, it is necessary to scale up and offer more and more assets on the platform over time. However, this could be limited and lead to a scalability issue since high-volatile crypto assets (the majority) don’t have enough liquidity and can be manipulated.

1. 基本介绍

2. 团队、融资、路线图

MatchNova由聊众前董事Nicky Jin领导，CMO为Raymond Wu（NFT项目FOMO Dog Club创办人），团队目前超过30人，来自微软、谷歌等企业，背景涉及区块链、AI和游戏等领域。

项目开始于2022年9月，在11月快速完成种子轮100万美元的融资，Aipollo Investment领投，LinkVC和Ace Direct International参投。

项目于2023年Q1进入alpha测试阶段，参与测试的玩家能共同瓜分$10,000 BUSD的奖励池。币安（BNB Chain）官方推特于4月4日发布了MatchNova宣传内容。

测试阶段结束后，MatchNova于4月底进行了创世NFT销售，10,000个创世NFT在开售30秒内被卖光。而在之后游戏正式发布的第一周内，MatchNova活跃用户超过3000人，游戏内比赛总数超50,000场。

2023年5月，MatchNova注册账号超过10,000，比赛场数超过50万，在DappBay排名上升至top15，并在台湾、日本和越南创建了玩家社区，成功在发行第一个月里实现了150%的增长，相关内容再次被BNB Chain点赞。

3.游戏模式与价格

MatchNova所有的游戏与社交活动都建立在NFT角色之上，除了最初的10,000个创世NFT，所有的NFT都是由用户铸造和持有的。所有的 NFT 都是从 1 级开始、最高29级。用户可以通过消费 MCC 来进行升级、每次升级需要固定的时间。时间长短则根据 NFT 级别逐渐增加。当NFT达到最高级别，玩家能定制NFT。

用户需要为 NFT 配备能量才能玩 PVP 三消游戏。每局游戏会消耗 1 点能量。每场比赛由 4-5 轮游戏组成，每位玩家每轮进行两次移动。玩家通过匹配至少 3 个相同颜色的棋子来得分。消除一件得 1 分。在最后一轮结束时，得分较高的玩家被视为获胜者。其中地图和对手是随机决定和匹配的。MCC将在比赛完成时奖励给每位玩家。

NFT 最大体力是 100，体力低于 50 要及时补充，因为体力低的时候，赚的 MCC 也会变少，少到不够修复体力，只能购买 MCC 来补充体力。恢复 NFT 生命力的唯一方法是等待。首场满体力游戏后，整整24小时内，体力将完全恢复。

MatchNova支持社交玩法，可以建房间邀请好友加入。游戏内置了钱包、加密货币交易等系统，希望引导Web2玩家以较低门槛进入Web3游戏。团队表示：选择在熊市开服是为了吸引真实的早期用户，过滤投机者。

基本价格：

MCC：0.2u；盲盒NFT地板：0.65 BNB；开盒NFT地板：0.65BNB

配置建议：

1个盲盒+4个开盒，5只NFT每天可以进行10场对战，MCC可以用来配置角色属性

玩家入场成本：（基于配置建议）

0.65 BNB* 5 + 200MCC

玩家回本周期：

35-60天

可能风险：

NFT与币价的市场波动；游戏输赢概率；项目方未来手动操作的风险；MCC换成稳定币需要抽本

4.经济模型

游戏代币：MCC （参考GST），主要用于游戏内各种消耗，如升级，恢复，增强，mint等

**治理代币：**WCC，固定供应量为20亿

治理代币具体分配：玩家（30%），生态系统（35%），私人投资者（15%），团队（15%），公共投资者 （3%），顾问 （2%）。

5.个人理解

MatchNova作为简单上手的gamefi，目前还在早期阶段，“好玩”是它现在最主要的吸引点，目前大陆玩家较少，以台湾地区玩家为主，用户群体氛围不错，因此目前币价稳定。但就第三点中针对游戏参与成本与回本周期的计算，试图借MatchNova实现gamefi获利，是有一定风险且相对缓慢的尝试。
