据官方消息,去中心化衍生品交易平台 OpenLeverage 将于今日 18 点开放治理代币 OLE 空投申领,同时上线 Gate 开启交易。 据悉,OpenLeverage 是 Binance Labs 第 4 季孵化计划中的 DeFi 项目。去年 7 月,OpenLeverage 完成 180 万美元种子轮融资,LD Capital 与 Signum 领投,FBG Capital、YBB Foundation 以及 Continue Capital 参投。 OpenLeverage 是一种无需许可的借贷和保证金交易协议,使交易者能够在 DEX 上做多/做空任何交易对,目前部署在以太坊和 BNB 链上,计划在 2022 年下半年扩展到其他与 EVM 兼容的链,如 Polygon、Avalanche、Arbitrum 和 Optimism。 举个例子,前段时间 BNB 链上的 GST(即bGST)价格暴涨,但缺乏做空机制,此时用户就可以使用 OpenLeverage 自行构建 bGST/BUSD 永续合约进行做空/做多。 首先,在 DEX (PancakeSwap)上为特定交易对创建两个独立的借贷池(bGST—BUSD),供用户进行保证金交易。接下来,借贷用户可以为两个池子分别添加流动性,提供 bGST 以及 BUSD 作为抵押品,并将收到代表质押收益凭证的 LTokens(LbGST或者LBUSD ,类似 Compound 协议的权益代币 ctoken),部分借贷池还将提供 OLE 代币奖励,LTokens 也可以重新质押到其他项目中以获得进一步的奖励。 当流动性添加完成后,用户就可以通过该池进行保证金交易。比如,用户本金是 200 BUSD 选择 3 倍做多 bGST,此时需要从借贷池中介入 400 BUSD;此后,bGST 行情上涨,用户获利平仓后,系统自动计算并偿还借贷资产以及利息,反之亦然。 需要注意的是,OpenLeverage 使用的是 DEX 提供的实时 AMM 价格进行计算,如果池子流动性较小,其价格可能波动较大。为了防止协议遭受闪电贷攻击,OpenLeverage 协议不允许借贷和还款在同一个区块中完成。因此,用户必须在单独的区块中开仓和平仓。 另外,贷方提供流动性可能获得收益,也可能由于行情极端异常,导致资产缩水;为此 OpenLeverage 设置了风险保护池(33% 的手续费用,由 DAO 管理),用以补贴贷方损失。此外,为了保持风险隔离,每个交易对都有一个独立的借贷池,即使使用类似的资产。举个例子,bGST/BUSD 和 BNB/BUSD 虽然都会使用 BUSD 作为抵押品,但两个池子相互独立,BUSD 也会根据用户自己选择分配到不到池子中。 代币方面,OpenLeverage 使用双代币系统:OLE 和 xOLE。OLE 是协议原生代币,由协议使用铸造,初始总供应量为 10 亿枚,7.35% 的 OLE(7350 万枚)将分配给历史活跃用户;OLE 持有者将 OLE 代币锁定到时间加权投票托管中以接收 xOLE,它对治理提案具有投票权,并有资格从保证金交易中收取产生的费用以及其他特权。 今年 4 月,OpenLeverage 正式上线,目前共有 275 个合约交易对,累计交易量达到 6.6 亿美元,TVL 超过 1270 万美元,总地址数达到 28617。 来源:金色财经 |
