About MANTRA

MANTRA is an EVM-compatible Layer 1 blockchain purpose-built for real-world assets, with native support for regulatory compliance. As a permissionless chain, MANTRA empowers developers and institutions to participate in the growing RWA tokenization space through advanced modular technology, compliance-ready features, and cross-chain interoperability.

“Permissionless blockchain for permissioned applications”

MANTRA holds a Virtual Asset Service Provider (VASP) license from Dubai’s Virtual Assets Regulatory Authority (VARA) to operate as a Virtual Asset Exchange and provide broker-dealer, management, and investment services.

Our work culture is intense and isn’t for everyone. Here’s the deal: we need hardcore builders, grinders who live for the hustle, ready to put in 60+ hours a week to make MANTRA industry-leading.

We are a winning team, and have high expectations for performance and delivering results. If you’re the type who thrives in driving innovation with relentless focus, this is your shot.

Join us, grind with us, and let’s build the future of crypto.
