At Hamsa, we believe that all of us have a part to play in creating a thriving, sustainable economy.

We believe that if the world’s leading financial institutions and the world’s top technology businesses work together we can revolutionize the $12T alternative assets market, and the global economy with it.

Today there is a $5T shortfall in private credit, meaning businesses around the world are struggling to operate or invest in their futures. On the investor side, with no common ledger for bills of exchange, no common risk assessment protocols, and no common marketplace, the alternative assets that do exist are largely illiquid and costly to manage.

Leveraging blockchain technology, digital currency and our unique rich data tokens, we are transforming the infrastructure that underpins the bank depository and alternative asset trading system. We are building an infrastructure that reduces the cost of managing alternative assets and that broadens access to this asset class for investors. An infrastructure that will enable banks and lenders to efficiently offer financing to more businesses, increasing liquidity worldwide

Together we are building an Enlightened Economy. A place where transparency reigns. Where we leverage the best of the existing financial system alongside the power of the blockchain. A place where everyone plays their part within a thriving, sustainable financial system.

Welcome to the Enlightened Economy.
