What is DeFi? What is decentralized finance?

4 Mins read

Decentralized Finance, also read as DeFi, is the new financing way. It allows the users to perform all the transactions online without any third-party invasion. It is entirely different from conventional banking methodology. One can send your money digitally with more efficiency and security. With DeFi, you can do all the things possible with the old banking way and enjoy new features and products coming in every day.

So, what are you waiting for? Let’s dive into this new era of financing and understand DeFi in detail.

How does DeFi work?

DeFi employs smart contracts, which eliminate the need for traditional financial institutions to act as guarantors for transactions; instead, players in the decentralized finance ecosystem deal with one another directly, and transactions are safeguarded using blockchain technology. Most DeFi solutions do not take custody of your cash, giving you complete control over your assets.

DeFi allows you to access your cash or assets using a secure digital wallet. When you wish to transact, you may do it using smart contracts, which means you and the other party agree to terms. For example, a smart contract may be formed to pay cash to a certain account on a regular basis, and this will continue as long as sufficient funds are available. A smart contract cannot be changed after it is created; therefore, cash cannot be re-routed and delivered to a different account.

Most DeFi apps are created on the Ethereum blockchain platform; however other platforms, including Cardano, Binance, and Solana, are rapidly creating comparable applications. DeFi is still in its starting phase compared to centralized financial systems; therefore, new applications are constantly being launched.

DeFi and Ethereum Applications

Ethereum is a logical fit for DeFi since it is a blockchain platform that allows decentralized apps (dApps) and smart contracts. The Ethereum blockchain stores transaction histories and account statuses, while Ether and other cryptocurrencies are utilized as assets.

Ethereum’s smart contract technology, which executes transactions automatically if specific criteria are satisfied, provides greater flexibility. Ethereum programming languages like Solidity are specially built for designing and implementing smart contracts.

For example, suppose a user wants money delivered to a buddy next Tuesday, but only if the temperature rises beyond 90 degrees Fahrenheit, as predicted by A smart contract can have such rules.

Ethereum hosts hundreds of DeFi apps with smart contracts at its heart, some of which are discussed below. Ethereum 2.0, a forthcoming upgrade to Ethereum’s underlying network, might help these apps by addressing Ethereum’s scalability difficulties.

DeFi Applications

Decentralized exchanges (DEXs)

Online exchanges allow users to trade one currency for another, such as US dollars for bitcoin or ether for DAI. DEXs are a popular sort of exchange that links users directly so they may trade cryptocurrencies with one another without entrusting their money to an intermediary.


A cryptocurrency is linked to an asset other than cryptocurrency (such as the dollar or euro) to stabilize its price.

“Wrapped” bitcoins (WBTC)

A method of delivering bitcoin to the Ethereum network so that it may be immediately utilized in Ethereum’s DeFi mechanism. WBTCs enable users to earn interest on bitcoin loans made using the decentralized lending networks outlined above.

Lending platforms

These platforms use smart contracts to replace middlemen, such as banks that manage loans in the middle.

NEW Projects in DeFi

Yield farming

Yield farming is an option for experienced traders prepared to take on risks. Users sift through numerous DeFi tokens in search of prospects for higher yields.

Liquidity mining

When DeFi applications lure consumers to join their platform by providing free tokens, this has been the most talked-about type of yield farming to date.

Money legos

To put the notion of “composability” another way, DeFi applications are like Legos, the toy bricks that youngsters click together to build houses, automobiles, etc. DeFi apps may be assembled similarly to “money legos” to create new financial solutions.

Lending Platforms

Lending markets are a prominent type of decentralized finance that links cryptocurrency borrowers and lenders. Compound, a popular website, allows users to borrow cryptocurrency or make their loans. Users can earn money by lending out their money and earning interest. Compound determines interest rates algorithmically; thus, interest rates will rise if there is a greater desire to borrow a coin.

DeFi lending is collateral-based, which means that to obtain a loan, a user must put up collateral, which is frequently ether, the Ethereum token. This implies that consumers do not have to reveal their name or related credit score to obtain a loan, as with traditional, non-DeFi loans.


Stablecoins, linked to stable currencies such as the US dollar or assets such as gold, seek to remove the high volatility associated with many cryptocurrencies. This means that stablecoins are more suitable for everyday transactions than other highly volatile cryptocurrencies. Stablecoins are simple to transport worldwide, making big sums of money more inexpensive and faster. Users may also earn interest using stablecoins.

What is DeFi Token?

Tokens are digital assets that are produced on a pre-existing blockchain. UniSwap, for example, is one of the Ethereum blockchain tokens.

How will I make money using DeFi?

The value of Ethereum DeFi projects has been skyrocketing, with many users gaining large sums of money.
Users may produce “passive income” by loaning out their money and earning interest from the loans via Ethereum-based lending apps, as indicated above. Yield farming, as previously mentioned, offers the potential for even higher profits but at a higher risk. It enables customers to use the lending feature of DeFi to put their crypto assets to work and get the highest potential profits. However, these systems are frequently complicated and opaque.
