### Strengthening Acceptance  
The results of the systematic review support that the factors that influence consumer acceptance of the adoption of blockchain in digital payment systems are four factors of UTAUT: performance expectancy, effort expectancy, social influence, and facilitating conditions. The performance expectancy significantly influences the adoption of digital payment. To be accepted, digital systems must be designed to be constantly valuable to users. Key performance expectancy elements include time-saving features, lower transaction fees, the non-physical presence of traders, and flexibility in payment, which attract users to adopt this payment system [25]. Effort expectancy, including ease of use and user-friendly features like easy navigation, speed of connection, and a quicker response, can significantly influence user behaviour towards adoption [25]. This study also highlights that the effort expectancy of the technology is directly related to its efficacy, with more accessible technology leading to higher acceptance rates. This encompasses the anticipated benefits of quicker and more efficient transactions and cost savings. The impact of anticipated effort on user acceptance is significant since delivering a user-centric experience prioritising ease of use, intuitive interfaces, and minimal technological barriers is crucial. The facilitating condition for blockchain usage is primarily influenced by IT infrastructure and organisation factors such as computers, Internet speed, and communication integration [2]. Blockchain-based adoption is directly influenced by providing the proper infrastructure, including technical and managerial support, which can significantly drive its adoption [25]. Social influence can also positively influence the acceptance of blockchain technology [69]. Furthermore, the influence of social factors on individuals' adoption of blockchain-based payment systems has considerable importance. The impact stems from several origins, including peer recommendations, endorsements from industry leaders, and the existence of engaged user communities. These factors are essential in cultivating acceptance and utilisation of blockchain-based payment systems [2; 25]. These elements are of utmost importance in facilitating a smooth and user-friendly migration to payment systems based on blockchain technology, hence fostering increased levels of user adoption. The success of blockchain technology in digital payment systems depends on the alignment between factors affecting adoption and consumer expectations. To make blockchain a viable choice, it is essential to consider augmenting trust and acceptance models to enhance the adoption of disruptive technology like blockchain in digital payment systems. This approach can expand the use of blockchain technology and make it a preferred method for digital transactions. Integrating Trust and Acceptance Factors to Reinforce Blockchain Adoption  
RQ3 aims to explore integrating the trust model with the acceptance model to enhance blockchain adoption in digital payment systems by observing the factors influencing the users' trust in and acceptance of blockchain technology in digital payment systems. The findings of the systematic review indicate a strong and beneficial relationship between trust and acceptance factors within the domain of blockchain-based digital payment systems. This implies that users' inclination to adopt and accept technology is influenced by their high degree of trust in several aspects of these systems, including transparency, security, privacy, and regulation. The conclusions are substantiated by several investigations, encompassing the works of [2; 21; 62]. The adoption of blockchain-based payment systems is significantly influenced by the level of trust exhibited by users. The propensity of consumers to adopt this technology is highly influenced by their trust in the security and transparency of transactions, as emphasised by previous studies conducted by [76; 78].
