Design a dynamic and visually appealing digital illustration for the main page of a DEFI service website. This image should creatively encapsulate the core services offered: crypto loans, staking, and swapping. The artwork should feature futuristic and symbolic representations of these services. Imagine a scene where digital coins or tokens are being securely exchanged, staked, or held as collateral in a sleek and high-tech environment. For crypto loans, illustrate digital currencies being locked in secure vaults or held in transparent spheres, signifying security and trust. For staking, depict coins or tokens generating new units, symbolizing growth and rewards, perhaps through a glowing, organic process. For swapping, visualize a fluid and seamless exchange of different digital currencies, using elements like intertwining streams or circuits. The color scheme should be modern and engaging, with metallic tones and highlights in the respective colors of popular cryptocurrencies. The overall look should be clean, professional, and should communicate the efficiency, safety, and innovation of the DEFI service --s 250
