Euler Finance

### What Euler is a non-custodial permissionless protocol on Ethereum that allows users to lend and borrow almost any crypto asset. Euler helps users to earn interest on their crypto assets or hedge against volatile markets without the need for a trusted third-party. ### Why? Euler introduces a number of new features in DeFi, including permissionless lending markets, protected collateral, reactive interest rates, per-second compounding interests and feeless flash loans. #### Permisionless listing Euler lets its users determine which assets are listed. Any asset that has a WETH pair on Uniswap v3 can be added as a lending market on Euler. #### Protected Collateral On Compound and Aave, collateral deposited to the protocol is always made available for lending. On the other hand, Euler allows collateral to be deposited, but not made available for lending. This collateral is 'protected'. It doesn't earn interest, but is free from the risks of borrowers defaulting, can always be withdrawn instantly, and helps protect against borrowers using tokens to influence governance decisions. #### Reactive interest rates Euler uses control theory to autonomously change the interest rates towards a level that maximises utilisation of assets in the protocol. These reactive interest rates adapt to market conditions for the asset in real-time without the need for ongoing governance intervention. #### Compound Interest Compound interest is accrued on Euler each second. This is different from other lending protocols, where interest is typically accrued every block. Earning interest per-second is generally expected to perform more predictably in the long-run, even if upgrades to Ethereum lead to changes in the average time between blocks. #### Feeless Flash Loans Euler only charges fees according to the time value of money, and from the blockchain's perspective flash loans are held for a duration of 0 seconds. Thus, they are entirely free on Euler (ignoring gas costs).

Ethereum

### What Ethereum is open access to digital money and data-friendly services for everyone – no matter your background or location. It's a community-built technology behind the cryptocurrency ether (ETH) and thousands of applications and smart contracts (computer programs living on Ethereum) you can use today. The Ethereum network is a network of computers all over the world that follow a set of rules called the Ethereum protocol, and it acts as the foundation for communities, applications, organizations and digital assets that anyone can build and use. Ethereum allows you to coordinate, make agreements or transfer digital assets directly with other people. You don't need to rely on intermediaries. And because no government or company has control over Ethereum it is impossible for anyone to stop you from receiving payments or using services on Ethereum. As mentioned before, Ethereum is not controlled by any particular entity and it exists whenever there are connected computers running software following the Ethereum protocol and adding to the Ethereum blockchain. Each of these computers is known as a node. Nodes can be run by anyone, although to participate in securing the network you have to stake ETH (Ethereum’s native token). Anyone with 32 ETH can do this without needing permission. ### Why Ethereum helps people and communities to coordinate in a resilient, open and trustworthy way on the internet. It also gives people the tools to have self sovereignty over their digital assets, and is particualrly important for people who have had to handle uncertainty around the security or soundness or mobility of their assets due to external forces outside of their control. The core value of Ethereum is that you can interact with the internet without trusting a central authority that could change the rules or restrict your access. The internet was meant to be a free and open space for everyone, and Ethereum builds on this premise, allowing you to control your own assets and identity, instead of them being controlled by a few mega-corporations.
