One of the biggest challenges in the space is bringing real-world assets on-chain in a trustless manner. One example is fiat currencies. While it’s possible to create a fiat-collateralized stablecoin like Tether, another approach is to gain synthetic price exposure to USD without having to hold the actual asset in custody with a centralized counterparty. For many users, price exposure is good enough. Synthetics provide a mechanism for real-world assets to be traded on a blockchain.
