Universal Market Access (UMA) is a protocol built on the Ethereum network that allows users to create custom, collateralised, synthetic cryptocurrency. The advantage is that this synthetic cryptocurrency can track the price of virtually all assets. In other words, UMA allows users to trade any asset using ERC20 tokens without having actual exposure to the asset itself. This allows people to gain exposure to assets that they won’t normally have access to. UMA opens a world of possibilities for DeFi. In summary, it puts derivatives on the blockchain. Instead of using a price oracle, users are given financial incentive to do price discovery by identifying and liquidating token issuers. The initial supply of UMA token was 100 million, but it has no hard cap and can be inflationary and deflationary.
