Design an imaginative and surreal digital artwork that encapsulates the essence of DEFI (Decentralized Finance) within a cosmic setting, accentuated by an array of purple bubbles. The focal point should be a dynamic and abstract representation of DEFI concepts such as blockchain, digital currencies, and smart contracts, merged seamlessly with cosmic elements like stars, nebulae, and galaxies. The artwork should feature a multitude of iridescent purple bubbles, floating and intertwining with these DEFI elements, symbolizing innovation, fluidity, and the interconnected nature of digital finance. The bubbles should vary in size and transparency, creating depth and a sense of movement within the cosmic landscape. The color palette should be rich in purples, blues, and metallic silver or gold accents, suggesting a blend of the mystical and the futuristic. The overall composition should be visually striking, conveying a sense of wonder, expansiveness, and the revolutionary spirit of DEFI in a cosmic context --ar 16:9 --s 250
