Cryptocurrency can be understood as a digital asset transacted among participants in the crypto economy. Every cryptocurrency must have an associated Blockchain. Blockchain is a Distributed Ledger Technology (DLT) which supports cryptocurrencies, this may be considered as the most promising disruptive technology in the industry 4.0 context. Decentralized finance (DeFi) is a Blockchain-based financial infrastructure, the term generally refers to an open, permissionless, and highly interoperable protocol stack built on public smart contract platforms, such as the Ethereum Blockchain. It replicates existing financial services in a more open and transparent way. DeFi does not rely on intermediaries and centralized institutions. Instead, it is based on open protocols and decentralized applications (Dapps). Considering that there are many digital coins, stablecoins and central bank digital currencies (CBDCs), these currencies should interact among each other sometime. For this interaction the Information Technology elements play an important whole as enablers and IT strategic alignment. This paper considers the strategic alignment model proposed by Henderson and Venkatraman (1993) and Luftman (1996). This paper seeks to answer two main questions 1) What are the common IT elements in the DeFi? And 2) How the elements connect to the IT strategic alignment in DeFi? Through a Systematic Literature Review (SLR). Results point out that there are many IT elements already mentioned by literature, however there is a lack in the literature about the connection between IT elements and IT strategic alignment in a Decentralized Finance (DeFi) architectural network. After final considerations, limitations and future research agenda are presented. Keywords: IT Strategic alignment, Decentralized Finance (DeFi), Cryptocurrency, Digital Economy.

翻译：加密货币可理解为加密经济参与者之间交易的数字资产。每种加密货币都必须关联一个区块链。区块链是支持加密货币的分布式账本技术（DLT），可视为工业4.0背景下最具颠覆性的技术。去中心化金融（DeFi）是基于区块链的金融基础设施，该术语通常指构建在公共智能合约平台（如以太坊区块链）上的开放、无需许可且高度互操作的协议栈。它以更开放透明的方式复现现有金融服务。DeFi不依赖中介和中心化机构，而是基于开放协议和去中心化应用（Dapps）。考虑到存在多种数字币、稳定币和央行数字货币（CBDCs），这些货币之间需要实现交互。在此交互过程中，信息技术（IT）要素作为赋能者和IT战略对齐发挥着重要作用。本文采用Henderson与Venkatraman（1993）及Luftman（1996）提出的战略对齐模型，通过系统文献综述（SLR）探究两个核心问题：（1）DeFi中常见的IT要素有哪些？（2）这些要素如何与DeFi中的IT战略对齐相关联？结果表明，文献已提及诸多IT要素，但关于去中心化金融（DeFi）架构网络中IT要素与IT战略对齐之间关联的研究仍存在空白。在最终讨论之后，本文提出了研究局限性与未来研究方向。关键词：IT战略对齐，去中心化金融（DeFi），加密货币，数字经济。
