- (Relative Stability) Anchored or Pegged => $1.00
- Chainlink Price Feed
- Set a function to exchange ETH & BTC - $$$
- Stability Mechanism (Minting): Algorithmic (Decentralized)
- People can only mint the stablecoin with enough collateral (coded logic)
- Collateral: Exogenous (Crypto)
- wETC
- wBTC
If under a threshold, 150% for example
Then someone pays back your minted DSC, they can have all your collateral for a discount as reward for safe-guarding the protocol.
This incentivizes people not to over leverage position on stablecoin, because the lose more than they borrow.
$DSC | Crypto | Amount |
---|---|---|
$100 DSC | ETH |
