Lybra is a decentralized stablecoin issuer developing the next generation of Liquid Staking Derivative (LSD)-based stablecoins.
Lybra works by allowing users to deposit ETH or stETH into the protocol and use them as collateral to mint eUSD, a stablecoin pegged to USD. The minimum collateral rate (MCR), or the lowest ratio of loan to collateral that will not trigger a liquidation (under normal mode) is 150%; user should strive to maintain at least a healthy ratio of 160% collateralization. The deposited ETH or stETH are then used to generate income through liquid staking derivatives (LSD), which are tokens that represent the staked assets and their staking rewards. The income from LSDs is then converted to eUSD and distributed to eUSD holders as a stable interest rate. Users can also redeem eUSD for ETH or stETH at any time by paying back their debt.
Lybra makes money by charging an annual service fee of 1.5% of the total amount of eUSD in circulation. Minting and redemption of eUSD are free of charge. The service fee accrues every second based on the current eUSD circulation and is allocated to the LBR staking pool (esLBR). esLBR (escrowed LBR) has the same value as LBR with the same total supply of LBR. esLBR cannot be traded or transferred but has voting rights and can share in protocol earnings.
You can mint and hold eUSD, which will earn you a stable interest rate of about 8% APY. You can also make money by buying and holding LBR tokens, which will give you a share of the protocol fees and rewards, as well as voting rights on the protocol governance. Additionally, you can provide liquidity to the LBR/ETH or eUSD/USDC pools on decentralized exchanges, which will earn you trading fees and liquidity mining rewards. Lastly, you can become a liquidator or liquidation keeper to earn ETH.
