Shield is a USDC-collateral stable coin that is generated by and used in Degis protocol. One Shield is fully collateralized by one USDC which means that Degis protocol should stake one USDC to mint one Shield. When a user puts in certain stable coins, Degis will call DEX protocol like Platypus and Curve to swap the stable coins to USDC and use the USDC to mint the equal amount of Shield.
If a user puts in USDC, we will directly mint Shield for the user. Degis will integrate Platypus first and support the following stable coins: DAI.e, FRAX, MIM, USDC, USDC.e, USDT, USDT.e. Then we will integrate Curve and support other stable coins like YUSD.
