Prezzo FEI Protocol

FEI is an algorithm-based stable coin. The FEI stablecoin has an uncapped supply that tracks demand. FEI enters circulation via sale along a bonding curve. This curve approaches and fixes at the $1 peg. When new demand for FEI arises, users can acquire it by buying on the bonding curve. The price function will start low to reward early adopters for purchasing FEI. Fei Protocol will support the creation of bonding curves denominated in any ERC20. The launch will contain only a single curve denominated in ETH. The mission of Fei Protocol is to create an entirely decentralized stablecoin. Therefore it is critical that no tokens issued by trusted third-parties (e.g. USDC, USDT, wBTC) be used as collateral on the bonding curve. This is a stance the development team hopes will be shared by the governance community post-launch. The ETH bonding curve will have a target FEI supply for bootstrapping before fixing the price at $1. This target is known as Scale; reaching Scale will denote the end of the bootstrapping phase. Scale will be set to 250,000,000 FEI, to be large enough to merit integration with other DeFi protocols. Post-Scale, the bonding curve price will fix at a governance-able buffer above the peg. This price creates a ceiling throughout the ecosystem. Arbitrageurs can buy on the bonding curve and sell on secondary markets if the price is higher elsewhere. Users cannot sell FEI on the bonding curve. Instead, the protocol retains the incoming ETH as Protocol Controlled Value (PCV). Fei Protocol deploys the PCV to create a liquid secondary market where users can sell FEI back into ETH.
