# TL;DR 👀

<mark style="color:purple;">**CEX vs DEX**</mark>&#x20;

<mark style="color:purple;">Centralized exchanges (CEXs) are platforms that allow users to buy and sell cryptocurrencies, operating as trustworthy brokers and custodians, keeping and safeguarding your cash</mark>

<mark style="color:purple;">Decentralized exchanges (DEXs) are an alternative to traditional centralized exchanges in which no single entity is in charge of the assets; instead, smart contracts and decentralized apps are used to automate transactions and trades</mark>

<mark style="color:purple;">**CeFi vs DeFi**</mark>

<mark style="color:purple;">Centralized finance (CeFi) enacts traditional financial services that are facilitated by centralized authorities, whereas decentralized finance (DeFi) operates on a trustless network that's enforced through smart contract technology</mark>

<mark style="color:purple;">**Algorithmic Stablecoins**</mark>

<mark style="color:purple;">Algorithmic stablecoins are a form of stablecoin that is backed by an on-chain algorithm that facilitates a change in supply and demand between them (the stablecoin) and another cryptocurrency that props them up</mark>

<mark style="color:purple;">**Airdrop**</mark>&#x20;

<mark style="color:purple;">An airdrop, as it pertains to cryptocurrency, is a marketing stunt that involves sending coins or tokens to wallet addresses in order to promote awareness of a new virtual currency</mark>

<mark style="color:purple;">**Liquidity Pool**</mark>&#x20;

<mark style="color:purple;">Liquidity pools are a collection of tokens or digital assets locked in a smart contract that provide essential liquidity to decentralized exchanges.</mark>

<mark style="color:purple;">**Impermanent Loss**</mark>&#x20;

<mark style="color:purple;">Impermanent loss is when the price of assets locked up in a liquidity pool changes after being deposited and creates an unrealized loss (in dollar terms) versus if the liquidity provider had simply held the assets in a crypto wallet</mark>

<mark style="color:purple;">**Swapping**</mark>&#x20;

<mark style="color:purple;">Swapping is an automated mechanism in DeFi for transferring assets by exchanging their existing tokens for new ones</mark>

<mark style="color:purple;">**Wrapped Token**</mark>&#x20;

<mark style="color:purple;">Wrapped tokens are assets that allow the value of a native asset from one blockchain to transfer to another blockchain</mark>

<mark style="color:purple;">**Arbitrage Opportunities**</mark>&#x20;

<mark style="color:purple;">Crypto arbitrage exploits temporary inefficiencies in asset prices during short intervals when a currency is available at different prices at the same time</mark>

<mark style="color:purple;">The currency is bought on the exchange where the price is lower and sold on exchanges where the price is higher to generate a profit.</mark>

<mark style="color:purple;">**Staking**</mark>&#x20;

<mark style="color:purple;">Staking is the process of locking crypto assets into a smart contract in exchange for rewards and generating passive income</mark>

<mark style="color:purple;">**Yield Farming**</mark>

<mark style="color:purple;">Yield farming is a passive income opportunity in which participants, known as liquidity providers, provide liquidity to cryptocurrency exchanges in exchange for rewards generated by transaction fees on a decentralized exhange</mark>

<mark style="color:purple;">**Total Value Locked (TVL)**</mark>&#x20;

<mark style="color:purple;">Total value locked (TVL) is the amount of user funds deposited in a decentralized finance (DeFi) protocol</mark>&#x20;

<mark style="color:purple;">These funds could be vested in the project for several functions, such as staking, liquidity pools</mark> <mark style="color:purple;">or lending</mark>

<mark style="color:purple;">**Gas Fee**</mark>

<mark style="color:purple;">Gas fees are the charges levied by developers to process transactions on a blockchain –– where the vast majority of DeFi transactions happen</mark>

<mark style="color:purple;">**Lending & Borrowing**</mark>&#x20;

<mark style="color:purple;">DeFi lending and borrowing offers innovations in efficiency, access and transparency compared to CeFi</mark>&#x20;

<mark style="color:purple;">Lenders provide borrowers with funds with the expectation that the borrowed amount is paid back with additional interest for providing immediate access to funds</mark>
