As per BeinCrypto, the COW token of decentralized finance (DeFi) protocol CowProtocol surged by nearly 40% after an address reportedly linked to the Trump family's World Liberty Financial (WLFI) purchased 759.36 ETH via CowProtocol. The development has brought increased speculative interest in the protocol as WLFI continues to interact with CowProtocol. This purchase has highlighted the growing adoption of DeFi protocols by traditional financial institutions. At the time of writing, COW is trading at $0.8957, up 39.58%, as per CoinMarketCap. CowProtocol is a decentralized lending platform that allows users to borrow and lend cryptocurrencies without the need for intermediaries. The protocol uses a unique algorithm to determine interest rates, which are based on supply and demand. The purchase by WLFI is a significant development for CowProtocol as it validates the protocol's technology and potential. It is likely that other traditional financial institutions will follow suit and begin to adopt DeFi protocols. This would be a major boost for the DeFi ecosystem and could lead to increased adoption of cryptocurrencies.
