Liquidity Pool

DEX (Decentralized Exchange)

A cryptocurrency exchange that operates without a central authority, allowing users to trade directly with one another through smart contracts. Unlike centralized exchanges, DEXs do not hold users' funds and typically do not require identity verification. Popular examples include Uniswap and SushiSwap, which use liquidity pools instead of traditional order books.

Yield Farming

A DeFi strategy where users provide their cryptocurrency to liquidity pools or lending protocols in exchange for earning interest, fees, or token rewards. Yield farmers often move their assets between different protocols to maximize returns, which can be lucrative but also carries significant risks. The rewards can come in the form of transaction fees, interest payments, or governance tokens.

Impermanent Loss

A temporary loss of value experienced by liquidity providers when the price ratio of the tokens they deposited into a pool changes compared to when they deposited them. The loss is called 'impermanent' because it can be recovered if the token prices return to their original ratio. However, if you withdraw your funds while the prices are still divergent, the loss becomes permanent and can outweigh the trading fees earned.

Smart Contract

A self-executing program stored on a blockchain that automatically enforces the terms of an agreement when predetermined conditions are met. Smart contracts eliminate the need for intermediaries by running code that is transparent and cannot be altered once deployed. They are the foundation of DeFi applications, NFTs, and many other blockchain-based services.
