UMA is a decentralized financial contracts platform built to enable Universal Market Access. UMA is designed to power the financial innovations made possible by permissionless, public blockchains, like Ethereum. Using concepts borrowed from fiat financial derivatives, UMA defines an open-source protocol that allows any two counterparties to design and create their own financial contracts. But unlike traditional derivatives, UMA contracts are secured with economic incentives alone, making them self-enforcing and universally accessible.
