I. Introduction
The emergence of new technologies has implications for how customers and organizations carry out transactions in business environments. There is a huge focus on flexibility and convenience from the customers while businesses look at cost and time efficiency. These are seen as drivers of technology acceptance in business settings in general and more specifically for payment platforms [1]. Businesses often aim to minimize costs through avoiding or even eliminating middlemen where possible while ensuring business operations continue smoothly. As such, Decentralized Finance (DeFi) technology “enables financial transactions and interactions happen by eliminating or marginalizing the need for traditional intermediaries” [2]. Cryptocurrencies are seen as a reflection of this emerging financial system because it promises cheaper, faster transactions that are peer-to-peer while ensuring efficiencies in asset transfers using protocols supported by the blockchain. In traditional markets, transactions are slower and more expensive considering the number of intermediaries. This is especially true in the case of cross-border payments that are not transparent, riddled with uncertainties, liquidity blockage and risk of frauds [3]. In a digital currency market, these inefficiencies are removed, while transaction time and costs are decreased. Furthermore, security of transactions is provided by the distributed ledger technology (DLT) which offers immutability of transactions, anonymity and privacy [4], with transactions being efficient and straightforward [5]. To this end, adopting cryptocurrency is appealing because: “users get to control their own money” [6]. Despite its appeal, the adoption of cryptocurrencies alone cannot be a panacea for all financial inefficiencies of the centralized, traditional markets or enable businesses to completely overcome issues such as economic rents that particularly have a huge impact on Small and Medium Enterprises (SMEs) [7]. Nevertheless, it is still imperative to explore the factors of adoption of cryptocurrencies among SMEs considering their need for digital transformation [8], highlighting the opportunities and challenges of such adoption [9] and to fill in the dearth of research in this domain [10]. The diffusion of cryptocurrency payment is particularly relevant for understanding UK SMEs sector because the HM Treasury in April 2022 announced its regulatory approach to DLTs and cryptocurrencies, emphasizing the government intention to facilitate the regulation and adoption of cryptocurrency and stablecoins, including exploring how it can regulate DeFi loans. As such Kalifa Report on UK Fintech (2021) [11] emphasizes that UK government regulations should (a) focus on delivering better outcomes to SMEs and (b) maintain the UK's position as the best place in the world for cryptocurrencies.
