Oasis is the most popular frontend interface to access the Maker protocol and mint DAI stablecoin on the Ethereum chain.
Oasis is the main frontend entrypoint to access the Maker protocol. Maker is a decentralized borrowing protocol that allows borrowers to draw loans against crypto assets like ETH as collateral. Loans are paid out in DAI, a USD pegged stablecoin with a collateralization ratio of at least 120%. The DAI peg is further supported by the Peg Stability Module (PSM). The PSM is a decentralized exchange that allows users to swap USD stablecoins for DAI at a 1:1 rate. Oasis Multiply allows users to borrow DAI and leverage their exposure by immediately swapping borrowed DAI for more collateral, all in one transaction. Oasis Multiply is built on top of the Maker Protocol and 1inch DEX aggregator. The feature uses Maker's flash loan module for borrowing DAI which is free. Multiply positions pay an ongoing stability fee to Maker like any other vault. When a Multiply position is created, DAI will be minted against collateral and swapped through 1inch for more collateral in order to increase exposure to the supplied collateral.
Maker collects a stability fee on all DAI generated through its smart contracts. The stability fee is a variable-rate fee that continuously accrues to the generated DAI by a user (must be paid in DAI). Oasis also charges a 0.2% fee for each token swap that takes place within a Multiply transaction.
You can deposit crypto assets on Oasis to mint DAI to be used across DeFi for lending and market making. The Maker vault can then be upgraded to a Multiply vault on Oasis to increase exposure to a supplied collateral through leverage. Oasis also offers a feature that allows you to earn Uniswap V3 higher trading fees with DAI through recursive leverage.
