very day more and more people understand the fundamental importance of DeFi. The idea of DeFi became possible to implement thanks to blockchain technology. After all, first of all, DeFi is the replacement of centralized facets of the financial system with decentralized databases. Now anyone can create a cryptocurrency wallet, replenish it and use DeFi to the fullest. This person opens up a diverse world of lending, replenishing a deposit, exchanging cryptocurrencies, sending to another person, and most interestingly, all this without a centralized governing body. But with its rapid popularity, DeFi has faced new challenges — scalability, security, transaction speed, and ease of use.
