DeFi中的永续合约NFT抵押品

总结

本文提出将加密货币永续合约的权益表示为非同质化代币，使其能够在可组合的去中心化金融中充当抵押品。文中将常用于代表DeFi资产价值的同质化代币与代表权益的NFT进行对比，后者较少被用作抵押品。该代币化方案旨在让永续合约头寸可用于借贷或去中心化交易所等更多DeFi服务。

作者使用Uniswap v3头寸NFT开展实验，评估这一概念。他们报告称，该方法在真实场景中可行，并展示了头寸NFT如何参与DeFi可组合性。摘录未提供实验细节、量化盈利结果或风险分析。因此，其论述在总体上支持这一概念的可行性，但无法证明其在不同协议或市场条件下的表现。

核心观点

  • 永续合约头寸可表示为赋予该头寸权益的NFT。
  • 作者提出将该NFT用作可组合DeFi服务中的抵押品。
  • 该方法基于由抵押品支持的加密货币永续合约。
  • 文中以使用Uniswap v3头寸NFT的实验作为验证。
  • 摘录未提供量化表现或风险细节。

# Perpetual Contract NFT as Collateral for DeFi Composability


# Perpetual Contract NFT as Collateral for DeFi Composability









Ethereum and its standardized token interface have formed decentralized finance (DeFi), an open financial system based on blockchain smart contracts. The DeFi ecosystem has become richer with the introduction of DeFi composability projects, such as Lido finance and Curve finance. DeFi composability denotes the concatenation of DeFi services in which each DeFi service locks assets as collateral and gives another asset as liquidity of locked assets to providers. Providers use the tokens given for other concatenated DeFi services, such as lending, decentralized exchanges (DEXs), and derivatives. The DeFi ecosystem uses ERC-20 tokens which can represent the value of an asset. ERC-721 non-fungible tokens (NFTs) are not widely adopted in DeFi, since they represent rights to an asset and are not considered appropriate for valuation. In this paper, we propose a new concept, perpetual contract NFT, which exploits perpetual future contracts in the cryptocurrency derivatives market. Unlike futures contracts in a traditional derivatives market, in the cryptocurrency derivatives market, most futures contracts are perpetual. In addition, the value of futures contract is backed by collateral. Therefore, if we mint the rights to perpetual contracts as NFT, we can use the perpetual contract NFT as collateral for DeFi composability. To validate our proposal and its profitability, we experiment with the position NFT of Uniswap v3. Through validation, we show that our concept works in real-world scenarios.
