Web3 is growing fast, decentralized finance (DeFi) is doing the same, and blockchain-based financial solutions are showing up everywhere, so demand for secure, scalable decentralized exchanges (DEXs) is rising. Businesses, startups, and even larger enterprises are investing in decentralized trading platforms to give users a transparent, permissionless, and safer crypto trading experience.
