Indigo is a protocol on Cardano that provides on-chain price exposure to real-world assets. It enables the creation of synthetic assets called iAssets, which replicate the price effect of holding the original asset. By utilizing stablecoins and ADA, anyone can create iAssets and benefit from the asset's price increase without owning it. Synthetic assets offer users exposure to various real-world assets without the need for ownership. The Blockchain's transparency, efficiency, low entry barriers, and decentralized nature facilitate the seamless delivery of these assets to anyone with internet access.
