Circle 为 Circle Mint 的机构推出了数字资产抵押借贷,使这些机构能够使用 BTC▲$77,666.00 作为抵押品换取其 USDC▼$0.9998 流动性,同时保持对其 BTC 的控制权,而不是将其出售。这是在 9 月 21 日的一份讨论 Circle Mint 支持 Arc 和 Ethereum 上多个第三方去中心化借贷市场的声明中宣布的。

存入原生 Bitcoin 的用户铸造 Circle Wrapped Bitcoin (cirBTC),机构将其移至用户控制的 Smart Wallet,在支持的借贷协议上将其作为抵押品发布,并以此抵押品借入 USDC。借入的稳定币随后自动从钱包转移到 Circle Mint 的客户账户。

Morpho 是发布时该协议支持的首个借贷协议。Circle 表示,包括 Aave 在内的其他协议预计将紧随其后,但尚未宣布是否或何时会添加。借贷市场是超额抵押的,利率、抵押率、清算价值和流动性由每个市场设定。

还款方式相同;客户可以将 USDC 从 Circle Mint 发送到 Smart Wallet,以偿还部分或全部债务。然后债务减少,抵押品根据底层协议的规则释放。然而,Circle 不提供贷款或控制清算。

Circle 的服务条款区分了 Circle Mint 持有的资产与 Circle 将资产部署到 DeFi 中的情况。数字资产抵押借贷由 Circle Technology Services 通过其界面和 Smart Wallet 技术提供。借贷和抵押品管理由第三方协议和智能合约处理,而 Smart Wallet 中的资产不再属于 Circle Mint 的受监管活动范围。

Smart Wallet 采用二分之二的多方计算密钥管理模型。据 Circle 称,客户保留对钱包的控制权,且公司无法授权或撤销用户的区块链交易。借款人还必须监控抵押品和协议条款,以避免超过清算限制。

Why this matters

The product gives compliant institutional Circle Mint customers a route to access USDC liquidity against Bitcoin without selling their BTC holdings. It could expand institutional use of DeFi lending markets across Arc and Ethereum, while shifting collateral, oracle, liquidity and liquidation risks to third-party protocols and smart contracts.

cirBTC 将原生 Bitcoin 网络与任何支持智能合约的网络连接起来进行借贷。Circle 表示,所有 cirBTC 均与 BTC 1:1 抵押,并可由第三方进行链上验证。这种包装资产与 Arc 和 Ethereum 交叉兼容,允许机构保持对其头寸背后的 Bitcoin 的风险敞口,同时利用以美元计价的流动性。

该服务目前仅适用于符合相关司法管辖区规定的机构 Circle Mint 客户。Circle Mint 账户不向个人提供,也不向纽约客户提供。Circle 指出了参与 DeFi 活动所涉及的智能合约、预言机、流动性和市场风险。

此次发布建立在 Circle 为 USDC 和 cirBTC 打造的机构基础设施之上,其信用由受监管的 Mint 托管进行线下支持,并为拥有 Bitcoin 储备的机构提供了直接获取包装抵押品和借入 USDC 的途径,同时保持所选支持 DeFi 的货币市场的利率和清算规则不变。
