Blur的NFT矩阵聚合之路:交易+借贷+稳定币

明明 2023-05-09 6

今天聊聊Blur的借贷协议Blend。

我两年前就说DeFi协议终会走向协议矩阵,交易+借贷+稳定币三种会整合到一起

今天看各大DeFi协议都折腾稳定币,走协议矩阵的路子。没想到,NFTFi的矩阵聚合势头来得比DeFi还要快。

当然,这背后推手是Paradigm 的丹叔;没有人比Dan更了解矩阵和聚合对DeFi的意义。

Dan 这个协议军师诸葛亮带着几个娃娃军四处卷,也是DeFi的一道风景。

Blur的NFT矩阵聚合之路:交易+借贷+稳定币

坊间传闻,当时 Uni V3如果没有Dan介入做了半个CEO加协议设计师,差点就难产。

他在几个核心DeFi设计都深入主导,早期的Compound,后来的Uniswap,可惜这两个团队都没有竞品(Aave, Curve)能折腾,都没搞成协议聚合。

这次找到Blur这个能打的,直接把聚合打法在NFTFi上实现。

我判断NFT毫无疑问也会走DeFi的矩阵道路,最终都会在交易及衍生品+借贷+稳定币里三剑合璧,所以还差一个USDB?

投资人做到奶爸级别,对项目方来说绝对是幸福的。Paradigm不仅送奶粉钱,论给项目方打工的敬业程度,不输任何创业者。

Blend的整个设计有Dan过往几个协议(Comp/Uni v3/TWAMM/Yield协议/永续期权)设计的招牌印记:无oracle, 无期限,仓位微分化等。

简而言之就是极大化协议自洽性,最终实现最大的非许可性和可组合性。

NFT借贷有两种模式,这两种模式其实都借鉴了 DeFi的借贷模型。

点对点和池子模式。

点对点模式(如NFTFi)需要供/需匹配,要指定贷款额度、固定利率、到期日,这种模式好处是无需预言机报价,双方撮合,对于借款人来说资金效率会更高,但有到期日对双方交互上摩擦巨大;对于贷款人来说,需要借款人匹配,资金效率比较低。

点对池子模式(BendDAO和ParaSpace)借鉴了DeFi的池子模型

将贷款人的资金汇集成池子,贷款利率通过资金使用率驱动,也就是贷款人的资金时刻处于部分被借状态,“资金使用效率”更高。

但这里有一个牺牲,那就是基本上是固定的抵押率(LT V),而且LTV设置倾向保守,比如Bend用floor price做LTV的基础,LTV偏低(40%);

ParaSpace在LTV上做出更多颗粒度。

LTV基于NFT系列的稀缺度分类,但无论怎么做,也难做到比点对点更细的颗粒度

谈到池子模式,大家的印象是资金效率高,那是对通用DeFi借贷而已。在NFTFi领域,这其实不是一个简单能回答的问题。

通用DeFi借贷是双边池子,而且大部分都可被借,因此资金效率对于贷款人和借款人都比较高。

但NFT池子并不是这样,现在NFT池子都是单边池(贷款池),借款人的抵押物是没有出借的。

因为NFT特殊性,普遍都用floor price作为LTV的基础,等于用NFT系列的最低价格作为整个系列借款的基础,短板决定长板,对于借款人来说,特别是蓝筹NFT,资金效率实际上是比点对点模式更低(借更少的钱)。

我们回过来看Blend解决了什么问题。

Blend采纳的是点对点模式,但做了几个改善,融合了池子模式的几个优点。

第一没有到期日,这个是对传统点对点模式最大的改进(后面谈衍生问题)。

第二是没有预言机,不依赖外部预言机,协议上有更大自洽性和安全性。它实际上把LTV本身给微分化,颗粒度无限细

这个对于借款人来说是更好的资本效率。

第三点对贷款人资金效率提高。贷款人的资金是可以多用的,既可参与Blur的bidding(dex流动性提供)同时可以做贷款人提供流动性;这是交易+借贷的资金聚合。

它实现了池子模式的某些优点,比如对于借款人来说可以“永续”借钱

对贷款人来说资金端因为存在一个拍卖竞争市场而且可以和bidding池公用,协议默认“乐观”滚存,没有强制到期再出借 。

但,天下没免费的午餐,我们谈谈这个模式的问题。

核心问题:这是对贷款人友好,对借款人不友好的协议设计。

对借款人来说,因为贷款人可任何时候发起“再融资”

借款人需要为这个贷款人的“选择权”支付更高的代价。

用房贷举例,就大概就知道多坑借款人了

假设你的房贷,银行任何时候可发起再融资拍卖,任何银行可竞价给你提供新资金,利率是从0%一直往上加,最终到一个位置,新银行愿意给钱替代你的原银行,而你这个借款人必须接受这个新条款。

这模式,银行随时可收回贷款,你作为借款人有三种选择:第一找到新银行给你贷款(你必须接受新条款,新贷款利率市场决定,可低、可高);第二还钱;第三以房抵债。

我感觉这种模式会被贷款人滥用,比如用低利息贷款引诱借款人上钩,然后频繁发起“再融资”,借款人稍不注意,NFT随时会被以物抵债

因为给贷款人自由选择权,它成本是很高的,它利率可能会比池子和传统点对点更高。

所以,很难说Blend是NFT借贷的最优模式。

我觉得NFT的借贷最终是两种模式并存,蓝筹等高价值NFT,点对点模式更适合;通用型NFT,池子模式会更适合。

最终无论是DeFi还是NFTFi都是卷资金效率,条条路通协议矩阵。
