iETH is synthetic Ether and was the first new iAsset whitelisted by the Indigo DAO for the Indigo Protocol. The Indigo Protocol is a CDP (Collateralized Debt Position) based DeFi protocol that brings capital-efficient synthetic assets to the Cardano ecosystem. Users can purchase iETH from a DEX just like any Cardano native asset, or can mint iETH within the Indigo Protocol by depositing ADA as collateral.
