The  cumulative  work  of  S.  Volosovich  and                    
A. Vasilenko (2019) is aimed at determining the 
place of Regtech in the ecosystem of financial 
technologies. The term Regtech refers to a set of 
technologies  that  optimize  the  control  system 
over  the  fulfillment  of  regulated  requirements. 
These technologies are aimed at facilitating and 
automating  the  submission  of  various  types  of 
reports, and data accumulation, but they are not 
devoid  of  many  risks.  The  mentioned  authors 
proved  that  the  digitalization  of  relations 
between  subjects  of  the  economic  sphere 
contributes to  the  digitization of  those  internal 
processes that take place locally in the institution. 
No  less  productive  is  the  collaboration  of 
scientists  M.  Korol and  S.  Parlag (2020), who 
studied  the  impact  of  digitalization  on  the 
banking  sphere.  In  their  works,  the  issues  of 
implementation of programs for the development 
of  the  banking  sector  of  the  economy, 
implementation  of  electronic  payments  and 
electronic  document  flow  in  the  banking 
institution, the emergence, problems, and further 
development  of  the  Fintech  market,  and  the 
provision of cyber protection were manifested in 
their works. 
 
O. Stashchuk and R. Martyniuk (2021) studied 
the processes of introducing innovations in the 
banking sphere, considering the need to improve 
the tools for ensuring financial security. 
 
S.  Reverchuk  and  O.  Tvoridlo  (2022)  also 
studied the peculiarities of the development and 
state regulation of banking services in Ukraine in 
the  conditions  of  digitalization.  The  authors 
considered  the  cryptocurrency  market,  the 
prospect of the creation and further functioning 
of neo-banks, and the activities of banks using 
digital technologies in general. The result of the 
research was, in particular, the consolidation of 
the  position  that  cryptocurrency  creates  many 
inconveniences  for  the  existing  economic 
system, which are connected, in particular, with 
the impossibility of controlling and monitoring 
the emission and circulation of cryptocurrency at 
the state level. 
 
The modernization of modern payment systems 
is analyzed by O. Dzyublyuk (2020). It can be 
seen from their content that electronic money is 
the latest financial instrument that will eventually 
replace traditional forms of monetary relations. 
The theoretician-economist was also engaged in 
the analysis of the place and role of electronic 
money  in  the  digital  economy,  its  further 
formation  and  functioning  in  ensuring  the 
movement  of  goods,  services,  and  works,  the 
need to implement monetary policy in order to 
ensure the financial stability of modern society. 
 
In the writings of O. Malakhova (2019), her own 
vision of approaches to the implementation of a 
system for the development and implementation 
of  digital  services  for  transactions is  revealed. 
The  scientist  determined,  in  particular,  the 
necessary  degree  of  involvement  in  the 
implementation  of  digital  technologies  in  the 
banking sphere of relevant specialist developers 
with  the  aim  of  adaptive  transformation of  the 
banking industry into a digital ecosystem. 
 
The basic theoretical foundation for the further 
study of digitalization in the sphere of economic 
relations was created by lawyer K. Nekit (2022), 
who treated digitalization from a legal point of 
view.  The  scientist  paid  a  lot  of  attention  to 
determining  the  legal  status  of  cryptocurrency 
both  in  Ukraine  and  abroad,  namely  in  such 
countries as the USA (or separate states), China, 
Canada,  Great  Britain,  Germany,  Austria, 
Estonia, Singapore, Portugal, Qatar, Bangladesh, 
Brazil,  Colombia,  Ecuador,  and  Bolivia.  The 
works  of  K.  Nekit  prove  that  leaving  crypto-
assets outside the legal field contributes to their 
use in illegal activities and deprives the state of 
significant  revenues  of  their  proper  taxation. 
Thus,  it  is  necessary  to  establish  the  legal 
regulation of the circulation of crypto-assets. 
 
The  articles  of  V.  Logoida  (2021)  are  also 
devoted to the study of foreign experience in the 
perception of digital assets using the example of 
cryptocurrencies.  The  scientist's  detailed 
comparative  analysis  included  the  countries  of 
Latin  America:  El  Salvador,  Mexico,  Brazil, 
Argentina, Cuba, Chile, Colombia,  Costa Rica, 
Ecuador,  Dominican  Republic,  Venezuela, 
Uruguay,  Panama,  Paraguay,  and  Bolivia.  The 
author researched the current legislative acts of 
the countries of the region and the main existing 
legislative  proposals  regarding  the  status  and 
circulation  of  cryptocurrencies,  in  particular 
bitcoin,  as  well  as  administrative  and,  in  part, 
judicial  practice  in  matters  of  qualification  of 
cryptocurrency as an object of civil rights. 
 
Qin  et  al.,  (2021)  took  a  closer  look  at 
decentralized finance, debuting as an ecosystem 
offering transparency and control, partly due to 
the integrity-protected underlying blockchain, as 
well  as  the  current  higher  returns  on  financial 
assets. 
 
The  analysis  of  the  works  of  the  above-
mentioned authors makes it possible to state that 
the issues of digitalization of the financial sphere
