UMA is a popular and essential asset for securing contracts that use UMA Protocol. It is not currently possible to be utilized as collateral on Aave to obtain other assets.
UMA Protocol is a community-led optimistic oracle built for Web3 that enables anyone to obtain a price on anything. UMA’s Optimistic Oracle enables a suite of products such as KPI Options, cross-chain bridges such as Across.to, Range tokens, Success Tokens and Call/Put Options.
UMA protocol has a current TVL of $100.3 million. AAVE will obtain a first mover advantage for enabling users to borrow against their UMA tokens. This proposal is to add UMA token as an asset on AAVE v2/v3 for users to use as collateral.
