JustLend, the largest of the three, has €1.9bn in deposits but only €67m borrowed, meaning only 3.5% of funds are actually used. JustStables, a DeFi system that already issues a dollar-pegged stablecoin (USDJ) on Tron, has $1300 billion in deposits, but only $288 million worth of stablecoins have been minted. And SunSwap, the third largest protocol, has very little activity outside of trading Tron's native cryptocurrency, TRX.
