In this article, you will learn what is Fei Protocol. Fei Protocol uses an algorithmic mechanism to maintain the stability of its native stablecoin, called FEI, which is pegged to the US dollar.
What is Fei Protocol?
Fei Protocol is a decentralized finance (DeFi) platform built on the Ethereum blockchain that aims to create a stablecoin that is not backed by traditional fiat currencies.
The algorithmic mechanism used by Fei Protocol involves the use of a stablecoin reserve, which is created through the minting of FEI tokens. Users can purchase FEI tokens using Ether (ETH) or other cryptocurrencies, which are then locked into the reserve. In order to To maintain the stability of FEI, the reserve uses a bonding curve mechanism that adjusts the price of FEI based on supply and demand.
The bonding curve mechanism works as follows: when the demand for FEI is high, the price of FEI increases, which incentivizes more users to sell their FEI tokens back to the reserve. This decreases the supply of FEI and brings the price back down to its pegged value. Conversely, when the demand for FEI is low, the price of FEI decreases, which incentivizes users to buy FEI from the reserve, increasing the supply and bringing the price back up to its pegged value.
Fei Protocol also offers a range of other DeFi products and services, including yield farming, liquidity provision, and governance, which are designed to incentivize users to participate in the platform and contribute to its ecosystem.
Why Did Fei Protocol Offer $10M Bounty?
An exploit enabled attackers to drain $80 million in crypto from decentralized finance (DeFi) platform Rari Capital's liquidity pools, according to a tweet by blockchain and smart contract audit firm BlockSec.
The BlockSec team called the security flaw a “typical reentrance vulnerability,” and tweeted again with a picture displaying the offending code.
Algorithmic stablecoin Fei—the self-touted “Stablecoin for DeFei”—also had contributed liquidity to Rari Capital's exploited pools. Fei has a market cap of well over half a billion dollars, making it the 11th largest stablecoin, according to data from Coin Gecko.
In December, Fei merged with Rari Capital. Rari enables the creation of so-called Fuse Pools—permissionless lending pools—that anyone with a wallet can access from anywhere to lend or borrow ERC-20 tokens. No minimum funds are required of users.
Fei and Rari's joint effort got off the ground with $2 billion in liquidity. Fei is trading a little below its peg, at $0.9895. as of this writing.
This isn't Rari Capital's first major exploit. In May of last year, a hacker stole 2.600 ETH (worth around $11 million at the time) from Rari Capital users.
At the time, CEO Jai Bhavnani said Rari team members would be sacrificing their RGT allocations and putting them toward the reimbursement. When the companies merged, Fei Protocol assumed some of Rari's liabilities stemming from that exploit.
Bottom Line
Overall, Fei Protocol represents an innovative approach to stablecoins and decentralized finance, and its success could help to further drive the growth and adoption of DeFi more broadly. This article is about what is Fei Protocol.
