GHO 将被设计为 Aave 上的原生去中心化多抵押稳定币,有望与 Curve、Maker、Frax Finance、Balancer 等产生更广的协同效应。 撰文:Karen 昨晚,Aave 向社区发布引入稳定币 GHO 的征求意见(ARC)提议,GHO 名称摘自 GHOsts,是一个 Aave 上的原生去中心化多抵押稳定币,具有以下特点: 除此之外,GHO 借款的利息将 100% 给 DAO,为 Aave DAO 产生额外收入。如果该提案获得社区批准,OpenZeppelin 和 PeckShield 将在未来几周内进行多项审计。 GHO 运行方式根据提议,GHO 由用户(借款人)创建,与 Aave 协议上的所有借款一样,用户必须提供抵押品(以特定的抵押品比率)才能铸造 GHO。当用户去偿还或者被清算时,GHO 协议就会销毁该用户的 GHO。GHO 铸币者产生的利息将直接转移到 AaveDAO 金库, GHO 引入了促进者(Facilitator)概念,一个促进者(例如协议、实体)具有无需信任地生成(和销毁)GHO 代币的能力。当然,任何促进者都必须得到 Aave 治理的批准。不同的促进者将能够对他们的 GHO 应用不同的策略,同时,促进者可以生成的 GHO 也会有上限,具体由治理决定。设置上限主要是为了保持抵押和降低风险。 提案通过后,第一个促进者为 Aave 协议。与 Aave 上其他资产一样,Aave 与 GHO 集成后也将部署 GHO aToken 和 GHO 债务代币。另外,GHO 借款利率将由 AaveDAO 确定,利率是稳定币的,不过也可根据市场情况进行调整。初始实施中,stkAAVE 持有者可以以一定折扣铸造 GHO,折扣参数由 Aave 治理决定,这意味着他们将为借入 GHO 支付较低的利率,也因此会激励更多的 Aave 去质押从而保护 Aave 协议。 Aave V3 & GHO今年第一季度,Aave 在 Polygon、Arbitrum、Avalanche、Fantom、Harmony 和 Optimism 上线了 V3,以太坊上可能还需要几个月时间才能部署。Aave 表示, V3 中的隔离模式、Portal 以及 E-Mode 等功能与 GHO 可谓是「天作之合」。此外,Aave 还打算在 Layer2 上推动 GHO 的采用。 Aave V3 中的隔离模式允许用户使用 Aave 协议当前支持的多种资产铸造 GHO,同时保持抵押并降低风险。此外,隔离模式还运行 DAO 治理控制供应和借贷敞口上限。 门户功能(Portal)会驱动 GHO 在多链上扩展(无需网桥),支持用户将资产通过不同网络在 Aave V3 市场之间无缝移动,比如,具体操作是用户在以太坊上销毁 aToken,然后在目标网络上铸造。 Aave V3 还有一个高效模式 Aave V3「E-Mode」,当抵押品和借入资产的价格是相关的情况下,可最大限度地提高资本效率,达到最大借款能力,如 DAI、USDC、USDT 以及 GHO 都是与美元挂钩的稳定币,所以这些稳定币属于同一个 E-Mode 类别。由于 E-Mode,稳定币持有者还可以以接近 1:1 的比率访问 GHO ,并且零滑点。 Aave 团队成员 MarcZeller 也指出,若 GHO 脱钩,就会产生一些套利空间保护系统。如果 GHO 出于任何原因高于挂钩,可以用另一种稳定币铸造 GHO 然后再通过稳定币兑换来卖出,Aave V3 的 E-Mode 就为用户提供了这种套利的操作条件。如果 GHO 拖钩,用户就可以去偿还债务,当有更多用户选择偿还债务后 GHO 总供应量就会降低,从而帮助恢复挂钩, 综上,尤其是 Aave V3 中的 E-Mode、门户功能以及隔离模式等核心功能会赋予 GHO 更多用例和场景,也有望与 Curve、Maker、Frax Finance、Balancer 等产生更广的协同效应。》 来源:金色财经 |
