Senior Solidity Developer About MANTRA

MANTRA has disrupted the status quo since 2020. As pioneers in the Web3 revolution, we've spent years building game changing decentralized protocols focused on empowering communities and democratizing finance.

Our journey began by fuelling grassroots DeFi activism. But we recognized the need to scale impact, bridging the divide between permissionless protocols and regulated systems. So we transformed, developing a first of its kind regulated DEX that's rewiring finance on a sovereign blockchain built from the ground up.

Now as this industry matures, MANTRA aims to connect TradFi with a new, blockchain native future. We're rebuilding finance through relentless product innovation.
