Blindex

Blindex is the first multi-currency stablecoin-based DeFi platform that sees all currencies as equals. Replacing all traditional financial systems calls for a completely stable, inclusive, and 100% decentralized alternative. We don't play around with centralized collateral.

The holder of BDX reserves.

Bot account
