About Us

VALR is Africa's largest crypto exchange by trade volume, founded in 2018 and headquartered in Johannesburg, South Africa. Serving over 1 million users globally, including 1,100 corporate and institutional clients, we’re licensed by the Financial Sector Conduct Authority (FSCA) in South Africa, with additional approvals to offer services in Europe and initial approval from Dubai's VARA. VALR distinguishes itself with a customer-first philosophy, delivering secure, transparent, and innovative solutions for both professional and retail traders.

Our Vision

Our vision is to create a world where finance unites rather than divides. Our name, derived from the word "valour" without distinction between American and British English, symbolises our commitment to universal values of courage, ethical integrity, and the intrinsic worth of every human being. These values drive us to design a platform that breaks down financial barriers, making it as seamless to send value across borders as it is to send an email.

Our Mission

At our core, we’re a values-driven exchange, dedicated to building a financial ecosystem that serves all of humanity. We believe in simplifying the complex world of crypto and blockchain to make it accessible to everyone, bridging the gap between traditional finance and the blockchain-powered future.

We’re Dedicated To

• Serving all Humanity: Inspired by the adage "it is expensive to be poor," we’re committed to creating a financial ecosystem accessible to all, challenging the status quo and reducing the frictions of outdated systems.
• Promoting Unity: Our platform reflects our belief in a socio-financial evolution. We envision a future where the global community is not defined by national boundaries but united by a shared vision of justice and prosperity.
