At Optimism, we're on a mission to scale Ethereum to the masses and sustainably fund public goods in the process!From the code to the values, we are Ethereum-aligned. We believe Ethereum has the potential to solve some of humanity’s most crucial coordination issues. Since our initial inception as a non-profit research group, we have sought to scale both its technology and values.At present the most pressing bottleneck to the growth of Ethereum is its performance and scalability. We are building the most elegant solution to this problem. We do this out in the open because we believe in open source and its ability to accelerate innovation.Not only do we improve Ethereum's performance by orders of magnitude, we donate 100% of the profits generated from doing so to Ethereum public goods. We do this because we believe the future of the open internet is too important to be left to chance. By operating as a Public Benefit Corporation we're able to align private incentives with public good and create a positive-sum economic model that provides a sustainable future for the internet.

Element is an open source protocol for fixed and variable yields. At its core, the Protocol works by enabling users to split the base asset (ETH, wBTC, USDC, DAI) of yield generating positions, such as a Yearn vault or an ETH2 validator, into two separate, fungible tokens: the Principal Token (PT), and the Yield Token (YT). One token represents the value of the base principal (called the Principal Token), and one token represents the variable interest gained from the yield generating protocol (called the Yield Token).
