About Us

Who We Are

CrowdSwap is the leading Decentralized Exchange in bringing simplicity, security, and innovative features into DeFi. Our goal is to facilitate mass adoption of DeFi by simplifying it to its core elements and cutting down on the excessive information found in other exchanges. In doing so, we make it accessible and enjoyable for everyone, from experienced traders to even grandparents. In addition to creating the best working DeFi services, we are pioneers in developing new features such as the first DeFi ETF and cross-chain investment. These unique solutions have saved our community and customers a significant amount of time, effort, and cost.

Our Story

CrowdSwap was set to start as a bulk swap solution on the Ethereum network, aiming to offer the crypto community a more affordable way to exchange their assets. However, when our co-founders, Christian and Vahid, began developing this solution, they identified a larger issue at play: usability challenges within the DeFi space. This realization led to a shift in CrowdSwap's mission. We committed ourselves to addressing the usability problems in DeFi, creating a superior method for investing in opportunities, and enhancing the existing cross-chain solution. Today, CrowdSwap provides the simplest and most efficient DeFi solutions in the market, has a unique approach to investments, and has one of the top cross-chain solutions available.

What Is Our Plan

CrowdSwap aims to continue developing the most practical services in its journey and present itself not just by showcasing them through our marketing efforts but also by allowing businesses to purchase and integrate these services. As a startup, we understand the struggles of building a project from scratch, that's why projects can take advantage of our innovative solutions such as Crypto Exchange widget which has been our core competency and perfected for years, Payment widget that enables businesses to expand their payment options to any token across multiple networks, API services for accessing accurate market data, and much more.
