Envision a sprawling, ultra-modern cityscape that represents the pinnacle of a future DEFI (Decentralized Finance) world. This crypto city should showcase advanced architectural designs, with skyscrapers and buildings featuring sleek, geometric shapes and a network of glowing, data-stream-like lights. Integrate elements that symbolize blockchain technology, such as interconnected nodes and digital grids, seamlessly woven into the infrastructure of the city. The atmosphere should be vibrant yet sophisticated, with a color palette dominated by cool blues, neon greens, and metallic hues, reflecting a high-tech financial ecosystem. Highlight areas that could represent financial hubs or trading centers, pulsating with holographic screens and digital displays showing cryptocurrency trends and data. The overall scene should capture the essence of a thriving, interconnected DEFI city, buzzing with innovation, digital currency exchanges, and a forward-looking spirit. --ar 16:9 --s 250
