Why Growr protocol?

Growr enables financial inclusion through fair & instant unsecured loans based on a self-sovereign identity and decentralized risk management, instead of requiring over-collateralization.

Loans with fair conditions

Growr creates a global decentralized marketplace to match supply and demand at the best possible price. This open free market creates fair conditions by enforcing the same rules for everyone.

Empowerment of local communities

Local players can use the protocol to facilitate access to credit by understanding the risk context and defining the right risk model, and social circles play an important role in referring borrowers and supporting them throughout the loan lifecycle.

Yield on excess capital

Investors across the globe can deploy their excess capital through the protocol and generate yield depending on their risk appetite.

Revenue growth for merchants

Merchants can grow their revenue by offering "buy now, pay later" type of credit facilities to their customers, facilitating origination and collection within the community.

Transparency in capital allocation

Growr enforces sustainable lending policies by embedding financial health incentives for borrowers, and enables end-to-end transparency down to the level of each individual borrower how investor's capital is allocated.

Instead of relying on risk data locked within proprietary databases, Growr provides an open credit record model, which also preserves the privacy of the borrowers through a self-sovereign identity.

How does it work?
