Understanding De-Fi : Liquidity Pools, Staking, and Trading on Decentralized Exchanges

De-Fi is an important part in the Crypto Verse. De-Fi means decentralized finance. It is a infrastructure to trade, safe and earn interest and lend.
There are often a lot of fancy names and difficult to understand concepts. This article won’t make you an expert on the field, but will give you the basic understanding what it means and what you can do with it and in some cases be a stepping stone to develop further.


De-Fi platforms leverage blockchain technology to create financial services that are accessible to anyone with an internet connection, bypassing traditional financial intermediaries. In this post, we’ll explore the core concepts of DeFi, including liquidity pools, staking, and trading on decentralized exchanges (DEXs).

De-Fi refers to a set of financial services and applications built on blockchain networks, primarily Ethereum. Unlike traditional finance, De-Fi is open, permissionless, and decentralized, allowing users to transact, borrow, lend, and invest without relying on banks or other intermediaries. This innovation is relatively new and offers amazing usecases. Though it does have some points to be noted. Most of crypto exploits and scams occur in De-Fi and trading on Ethereum can have very high fees.

Liquidity Pools: The Heart of De-Fi

  1. Central to De-Fi are liquidity pools, which enable decentralized trading and lending. A liquidity pool is basically a pool (or central point) where liquidity (coins) are gathered in 1 place.
    These pools are made up of digital assets provided by users. Liquidity providers deposit their tokens into a smart contract, forming a pool. In return, they receive liquidity pool tokens that represent their share of the pool. And for this, they receive a share of the fees that are charged for using the platform.
    To difficult to understand? Imagine a group of people standing in a circle, everyone (or the wealthy few in the circle) places something in the middle of the circle, and everyone around the circle can make use of it. In return those that places something in the middle get a fee everytime it is used

How Liquidity Pools Work:

  • Trading: Liquidity pools facilitate decentralized trading. When you want to trade one asset for another, you can do so directly on a DEX using the liquidity pool’s assets. The price is determined by an automated algorithm based on supply and demand. So because people offer assets to the pool (the coin which you want to trade and a paired coin, like Eth or USDT), the rest can make use of the coins that are provided. The one who provided the coins gets rewards for this. By this infrastructure people can trade with each other, instead of having to trade with a centralized company who manages all the trades.
  • Earning Fees: Liquidity providers earn a portion of the trading fees generated in the pool. This incentivizes users to supply liquidity and helps keep the market liquid.
  • Impermanent Loss: Liquidity providers should be aware of impermanent loss, a potential risk when the prices of the assets in a pool change. It’s important to understand this risk before providing liquidity.

Staking: Earning Rewards for Participation

Staking is another key aspect of De-Fi, allowing users to earn rewards by locking up their tokens in a blockchain network. Staked tokens help secure the network and validate transactions. In return, stakers receive additional tokens as rewards.

How Staking Works:

Validators: Some blockchains use a Proof-of-Stake (PoS) consensus mechanism. Validators are users who lock up a certain amount of cryptocurrency to propose and validate new blocks. They receive rewards in the network’s native token. 

  • Delegated Staking: Users can also delegate their tokens to validators, who share a portion of their rewards with the delegators. Some networks require a minimum amount of coins, which could be worth a high price. Not everyone can afford this. Also it requires you to keep your connection and network connected at all times. By using someone else’s network you don’t have to comply with this. Someones else complies, you just offer up a small piece. And if many people offer a small piece to 1 party, that party can comply. So you can join with a small amount and don’t need to be connected at all times.

 Yield Farming: Staking can be combined with yield farming, where users provide liquidity to DeFi protocols and earn rewards for their participation. These project may offer a high APY (the percentage of rewards), but a high level of rewards is often unstable and may result in the value of the reward diminishing.


    Trading on DEXs: Decentralized Exchange

    Decentralized exchanges (DEXs) are the backbone of De-Fi trading. These platforms allow users to trade cryptocurrencies directly from their wallets without the need for a centralized intermediary.
    They offer a number of advantages over traditional cryptocurrency exchanges, such as security, transparency, and efficiency. There are some downsides though, like you have to pay fees to use the network, therefore trading is often more expensive than on a centralized exchange. The liquidity is often lower as well, meaning the price impact will be higher.

    That is De-Fi in a nutshell. It offers great possibilities. However, it’s important to approach De-Fi with caution. Due to its open and decentralized nature, the De-Fi space can also be risky. Users should conduct thorough research, understand the risks involved, and consider using platforms with strong security measures and audits.
