Fintech companies face the challenge of trying to lead in AI adoption while navigating potential pitfalls. The board of directors plays a critical role in demonstrating leadership and building trust with key stakeholders during the implementation of AI.

This research interviewed board members from Fintech companies to identify the most effective strategies for fostering trust among shareholders, staff, and customers. These three groups have different concerns and face different risks from AI. The findings reveal that the most effective methods for building trust differ among these three groups of stakeholders. Leaders should build trust for these three stakeholders in two ways: First, through the effective and trustworthy implementation of AI, and second, by transparently communicating how AI is used in a manner that addresses stakeholders concerns. The practical ways to build trust with the implementation and the communication for these three groups, shareholders, staff, and consumers, are presented in tables 1-3.

The findings show significant overlap between the effective overall implementation and governance of AI. However, several issues are identified that relate specifically to how AI innovations should be communicated to build trust. The findings also indicate that certain applications of Generative AI are more conducive to building trust in AI, even if they are more restrained and limited in scope, and some of Generative AI’s performance may be sacrificed as a result. Thus, there are trade-offs between unleashing Generative AI in all its capacity and a more constrained, transparent, and predictable application that builds trust in customers, staff, and shareholders. This balancing act, between a fast adoption of Generative AI and a more cautious, controlled approach is at the heart of the challenge the board faces.

Leaders and corporate boards must build trust by providing a suitable strategy and an effective implementation, while maintaining a healthy level of scepticism based on an understanding of AI’s limitations. This balance will lead to more stable and sustainable trust.

Table 1. How leaders can build trust in AI with shareholders

Implementation 1) Use AI in a way that does not increase financial or other risks. 2) Build in-house expertise, don’t rely on one consultant or technology provider. 3) Make new committee focused on the governance of AI and data. Accurately evaluate new risks (compliance etc.). 4) Develop a framework of AI risk that board will use to evaluate and communicate risks from AI implementations. Management should regularly update the framework. 5) Renew board and bring in more technical knowledge and have sufficient competence in AI. Keep up with developments in technology. Ensure all board members understand how Generative AI and traditional AI work. 6) Make the right strategic decisions, and collaboration, for the necessary technology and data (e.g. through APIs etc.).   Communication 1) Clear vision on AI use. Illustrate sound business judgement. Showcase the organization’s AI talent. 2) Clear boundaries on what AI does and does not do. Show willingness to enforce these. 3) Illustrate an ability to follow developments: Show similar cases of AI use from competitors, or companies in other areas. 4) If trust is concentrated on specific leaders that will have a smaller influence with the increased use of AI, the trust lost must be re-built. 5) Be transparent about AI risks so shareholders can also evaluate them as accurately as possible.

Table 2. How leaders can build trust in AI with staff

Implementation 1) Show long term financial commitment to AI initiatives. 2) Encourage mindset of experimentation but with an awareness of the risks such as privacy, data protection laws and ethical behaviour. 3) Involve staff in process of digital transformation. Share new progress and new insights gained to illuminate the way forward. 4) Make AI ethics committee with staff from a variety of seniorities. 5) Give existing staff the necessary skills to effectively utilize Generative AI, rather than hiring new people with technological knowledge that do not know the business. Educate staff on when to not follow, and when to challenge the findings of AI. 6) Key performance indicators (KPIs) need to be adjusted. Some tasks become easier with AI, but the process of digital transformation is time consuming.   Communication 1) Communicate a clear coherent, long-term vision, with a clear role for staff. The steps towards that vision should reflect the technological changes, business model changes, and the changes in their roles. 2) Be open and supportive to staff reporting problems, so whistleblowing is avoided.

Table 3. How leaders can build trust in AI with customers

Implementation 1) Avoid using unsupervised Generative AI to complete tasks on its own. 2) Only use AI with clear transparent processes, and predictable outcomes, to complete tasks on its own. 3) Have clear guidelines on how staff can utilize Generative AI, covering what manual checks they should make. 4) Monitor competition and don’t fall behind in how trust in AI is built.   Communication 1) Explain where Generative AI and other AI are used and how. 2) Emphasise the values and ethics of the organization and how they still apply when Generative AI, or other AI, is used.

Decentralized finance (DeFi) is becoming more and more popular. Decentralized exchanges (DEX) are a type of DeFi that allow users to trade freely and anonymously on a blockchain.
There are two platforms for cryptocurrency trading, centralized exchange (CEX) and DEX. Most of the exchange volume is happening at CEX because they are easier to use. However, DEXs volume is catching up. The reasons for the popularity of DEXs are linked to the unique advantages of DeFi. First, CEX is a business that requires Know Your Customer (KYC). It requires customers’ identification for registration to comply with anti-money laundering regulations and any other laws from the countries its customers come from. Because of this, users are still concerned about several issues such as privacy and the risk of their wealth being confiscated.
This study focuses on how external factors affect the adoption of DEXs and provides suggestions for the development of the entire DEX industry. The study finds that the expansion of the DeFi industry has a significant impact on the adoption of DEXs, so DEXs should cooperate to develop the industry instead of focusing on competing for a larger share of the existing market. Some other external factors also have an impact, such as technological innovation, partner integration and community support. As DeFi is closely related to the adoption of DEX, the study also discusses the external factors that may affect the adoption of DeFi, namely trust, infrastructure, and regulation.

Figure 1. The factors that affect the adoption of Decentralised Exchanges DEX


Related research is mainly focused on the difference between DEXs, and tries to find how a DEX can gain an advantage over other DEXs, but this research concentrates on the external factors to show how to encourage DEX adoption. While market fluctuations may attract short-term attention and reactions, the long-term development of DEX relies on a stable user base in DeFi and continued expansion of the industry.
This research enriches the theoretical framework of DeFi and sheds light on the relationship between DeFi and DEX. A DEX relies on the liquidity of DeFi, with higher liquidity on the blockchain, the DEX liquidity is expected to be higher, leading to slippage, which means the loss that users suffer when trading on DEX, is reduced. This research provides new insights into understanding the liquidity dynamics of DEXs, extending existing theory on the interplay between liquidity and transaction costs.

(chapter 4 in book)
Central bank digital currencies (CBDC) have been implemented by some countries and trialled by many more. As the name suggests, the fundamental characteristics are that this is money that is digital, without a physical note or coin, and issued by a central bank.
The consumer has an increasing range of financial services to choose from including decentralised blockchain based cryptocurrencies. A CBDC may use blockchain technology, but it is centralized, so the institutions that support it play an important role. While being centralised may reduce some risks, it may inadvertently increase others. Despite the centralised top-down nature of this financial technology, it still needs to be adopted so the consumer’s perspective, particularly their trust in it, is very important. Each CBDC implementation can be different, and each country’s context can be different, therefore it is important to understand each case separately.
This research models the Brazilian consumer’s trust in their two-tier CBDC, where the central bank and the retail banks retain their current role (Zarifis and Cheng, 2025). This implementation is not a one tier solution where retail banks are bypassed in some ways, and the citizen interacts mostly with the central bank.
Existing research that identified six ways to build trust in a different CBDC (Zarifis and Cheng, 2024) was used as a basis. This research tested a model with one additional way to build trust, but this additional way to build trust was not supported. The seventh hypothesized way that is not supported is that the implementation process, including pilot implementations, would build trust. Therefore, despite the differences in the Brazilian CBDC, the original model applies here also which suggests the model applies for both two-tier solutions, and mixed one and two-tier solutions.

Figure 1. Model of consumer trust in Brazil’s two-tier CBDC, adapted from (Zarifis and Cheng 2024)

Three institutional, and three technological factors, are found to play a role. The six ways to build trust that are supported are: (a) Trust in government and central bank offering the CBDC, (b) expressed guarantees for those using it, (c) the favourable reputation of other active CBDCs, (d) the CBDC technology, the automation and limited human involvement necessary, (e) the trust building features of the CBDC wallet app, and (f) the privacy features of the CBDC wallet app and back-end processes.
It is important to develop user centered services in Brazil so that trust is built in the services themselves, and the government institutions that deliver them, sufficiently for broad adoption.

Different organizations see this period of transition and adjustment as either an opportunity or a threat. Some from outside the financial sector such as bigtech see it as an opportunity to take market share. Others have managed to limit competition and have regulatory ‘moats’ around the financial services they provide, that they would prefer to maintain. Whether an existing financial organization decides to keep their existing model, disrupt themselves in a drastic way, or evolve gradually into a new business model, it is important that they understand this multifaceted transformation. While startups are like agile speedboats that can change direction easily, large financial organizations more closely resemble large cruise ships that need to know where they will be in five years’ time, before setting a course to get there.

This research finds support for six Fintech business models that are optimised for AI and blockchain. These are (1) focus on less financial services and disaggregate, (2) absorb AI into existing financial model, (3) incumbent in finance expanding beyond current model, (4) new dedicated startup in finance disrupting the established ways of operating, (5) tech company disrupting finance, (6) disruptor not focused on technology with extensive user-base. The first three models involve organizations that are already active in the finance sector. The last three models are new organizations using AI to start offering financial services.

While the sixth model has similarities to the fifth, it also has some distinct features. The key characteristics are that it has an existing user base, with which trust has already been built, and unlike the fifth model, it uses advanced but commoditised financial technology. Despite the ongoing innovation, some Fintech transitioning into a commoditised service, that is easily deployed, is a sign of a maturing sector.

It is important to appreciate that existing trust with customers or fans, or the ability to build trust, are important parts of the value chain. Having the capability to build trust can be the starting point, with financial services added to it. Is the technology still the most critical factor in a Fintech at this stage, or the ability to build trust in it? Words such as modularity and ecosystem are often used, but it is important to understand how a new Fintech can be created, its journey and how it can build momentum and carve out a niche with technology and trust.
