Degenerative Finance is an innovative series of DeFi derivatives co-developed by Yam Finance and the UMA project. uGas is an Ethereum gas fee futures contract, while uGAS is a synthetic token that integrates this contract. Each uGAS token is named after the expiration month of its respective futures contract, such as the uGAS-JAN21 futures contract token, which indicates that the uGas contract will expire at 0:00 UTC on February 1st, 2021 (end of January). Upon expiration, the uGas contract settles based on the median gas price of all transactions on the Ethereum network over the past 30 days. Each uGAS futures contract token represents 1 million gas, so if the 30-day median gas price is 70 Gwei, the price of each uGAS futures contract token would be 0.07 ETH.
