$DENI currency can be lent to the United Free Peoples Reserve, earning a yield. The United Free Peoples Reserve uses these funds to lend to people on the Terrae world who may be looking for leverage to invest in swap pools, yield farming, etc. In the initial days of the Age of Revolution (during the first months of the Terrae protocol), borrowing operations will not yet be enabled. The Reserve will use funds from the genesis of $DENI to compensate the first lenders. In the long term, borrowing and lending activities will have variable APY.
The Bank, also known as the Reserve of the Free Peoples, lend and borrow $DENI to Terrae citizens.
