It sounds good, but isnt it too risky? As i understood, this system is under no ones control, even the law cant help lenders, if borrower refuse to pay

Thats why interest rates are higher, in order to maximise lender's profits. Risk/profit ratio must be interesting to investors
In case of TokenLend loan originator will have as collateral real estate assets of the borrower. Therefore greatly reducing risks of losses related with this loan.
