Due to its specifics, DeFi attracts participants all over the world, allowing you to fully take advantage of blockchain technologies. This article presents arguments emphasizing the key importance of interest rates in shaping the behavior of participants, allocating resources, and balancing supply and demand of financial products and services. The article also examines the impact of interest rates on the stability and efficiency of decentralized financial systems. In addition, it examines various approaches to setting interest rates in these ecosystems, including market mechanisms and algorithmic models.</p></abstract><trans-abstract xml:lang="ru"><p>Децентрализованное кредитование является одной из ключевых услуг в сфере децентрализованных финансов. Благодаря своей специфике, DeFi привлекает участников по всему миру, позволяя в полной мере использовать преимущества блокчейн технологий. В данной статье приведены доводы, подчеркивающие ключевое значение процентных ставок в формировании поведения участников, распределении ресурсов и балансировки спроса и предложения финансовых продуктов и услуг. В статье также исследуется влияние процентных ставок на стабильность и эффективность децентрализованных финансовых систем. Кроме того, в ней рассматриваются различные подходы к установлению процентных ставок в этих экосистемах, включая рыночные механизмы и алгоритмические модели.</p></trans-abstract><kwd-group xml:lang="en"><kwd>blockchain</kwd><kwd>decentralized credit protocols</kwd><kwd>digital economy</kwd><kwd>digital financial assets</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>блокчейн</kwd><kwd>децентрализованные кредитные протоколы</kwd><kwd>цифровая экономика</kwd><kwd>цифровые финансовые активы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Qin K. et al.
