USDC tokens used as collateral for the minted IRON stablecoin tokens is stored in the protocol’s time-locked collateral smart contract, however, in optimal conditions, the daily redemptions are only a small part of the supply of IRON token. In this case, a large portion of this collateral is idle and economically speaking inefficient. Vaults changed this by investing a large portion, but not all of the USDC token collateral to generate passive income to the protocol and to the TITAN single token staking pool to incentivize TITAN purchases and staking.
