What is Decentralized Finance (DeFi)?<\/strong><\/h2>\n\n\n\n
DeFi is an umbrella term for a variety of different financial services built on a blockchain. Unlike traditional banking and financial institutions, DeFi has no central authority or middlemen regulating your funds, accounts and transactions. Hence, it\u2019s called decentralized finance.\u00a0<\/p>\n\n\n\n

<\/figure>\n\n\n\nAs mentioned, DeFi is not a singular entity. Anyone can build their own DeFi applications and protocols with the help of smart contracts and blockchain technology. More on this later. <\/p>\n\n\n\n
To put it into perspective, here are a few limitations of traditional finance –<\/p>\n\n\n\n
- Transferring funds from one account to another takes time. Sometimes days. <\/li>
- You have to pay the banks and intermediaries for their services. <\/li>
- You don\u2019t have complete control over your funds. <\/li>
- Banks can track your transactions and access your personal data, like name, phone number and address, since they are essential to set up a bank account. <\/li>
- Traditional financial operations are vulnerable to human errors and limitations. <\/li><\/ul>\n\n\n\n
Now, in contrast to traditional finance, here\u2019s how DeFi compares – <\/p>\n\n\n\n
- Transferring money is instantaneous. <\/li>
- Since there are no central authorities or middlemen, you pay no fees or charges. However, crypto transactions may be subjected to gas fees and other costs. <\/li>
- Complete control over your assets. Only you and you alone can access your funds with crypto wallets. <\/li>
- Anonymous and decentralized. No one can track your transactions or gain access to your identity. (This, of course, poses a risk of financial crimes)<\/li>
- Smart contracts eliminate the need for human supervision. <\/li><\/ul>\n\n\n\n
These are just a few of the many attributes of DeFi. With constant innovations and evolution, this will only expand in the coming years. <\/p>\n\n\n\n
How Does it Work?<\/strong><\/h3>\n\n\n\n
The entire DeFi infrastructure stands on the back of smart contracts. Smart contracts replace and automate tasks usually done by banks and other financial institutions. <\/p>\n\n\n\n
Smart contracts are self-executing contracts between a buyer and a seller written in code. In other words, whenever a predetermined set of conditions are met, the smart contract will automatically execute the transaction between the two parties. <\/p>\n\n\n\n
Ethereum was the first blockchain to introduce smart contracts in crypto transactions. That is why most DeFi protocols are built on top of the Ethereum blockchain. <\/p>\n\n\n\n
But in recent years, DeFi applications have expanded onto other, some may argue, better blockchains that use smart contracts, like Solana, Binance Smart Chain and Avalanche. <\/p>\n\n\n\n
Most of these DeFi applications function as Decentralized Autonomous Organizations (DAO). You can read our in-depth guide on DAO<\/a>, but on the surface, these are organizations with no central authority where the members or users make decisions with the help of governance tokens.\u00a0<\/p>\n\n\n\n
That is how most DeFi protocols work. <\/p>\n\n\n\n
Most Popular DeFi Applications<\/strong><\/h2>\n\n\n\n
So far, we’ve only discussed the fundamentals of DeFi and how it works. The following are some of the most popular DeFi applications that display its use in action. <\/p>\n\n\n\n
Decentralized Exchanges<\/strong><\/h3>\n\n\n
\n![\"Decentralized](\"https:\/\/bitcoin.tax\/blog\/wp-content\/uploads\/2022\/12\/Decentralized-Exchanges--1024x1024.png\")
<\/figure>\n<\/div>\n\n\nDecentralized exchanges (DEX) are peer-to-peer marketplaces where traders can directly trade pairs from their crypto wallet with the help of liquidity pools and automated market makers.\u00a0<\/p>\n\n\n\n
Check out the difference between centralized vs decentralized exchanges<\/a>.\u00a0<\/p>\n\n\n\n
UniSwap, PancakeSwap, Bisq, and Shapeshift are some of the most popular DEX platforms. <\/p>\n\n\n\n

Liquidity Pools<\/strong><\/h3>\n\n\n
\n![\"Liquidity](\"https:\/\/bitcoin.tax\/blog\/wp-content\/uploads\/2022\/12\/Liquidity-Pools-Decentralized-Finance-1024x1024.png\")
<\/figure>\n<\/div>\n\n\nAs we briefly mentioned in the last section, liquidity pools are an integral part of decentralized exchanges. <\/p>\n\n\n\n
To facilitate trading, every platform and every protocol needs liquidity. Liquidity pools are crowdsourced collections of crypto funds (contributed by liquidity providers) locked in a smart contract that helps facilitate decentralized trading.<\/p>\n\n\n\n
Anyone can become a liquidity provider. Liquidity providers receive a part of traders\u2019 trading fees as a reward for their contribution. This has become a primary source of passive income for many crypto investors who don\u2019t want their assets to sit idle. <\/p>\n\n\n\n
Check out our list of the 10 Best Liquidity Pools<\/a>.\u00a0<\/p>\n\n\n\n
DeFi Staking Crypto<\/strong><\/h3>\n\n\n
\n![\"\"](\"https:\/\/bitcoin.tax\/blog\/wp-content\/uploads\/2022\/12\/DeFi-Staking-1024x1024.png\")
<\/figure>\n<\/div>\n\n\nBy staking your cryptocurrencies in a network, you can become a validator for its blockchain. A validator is someone who validates transactions and receives newly minted coins and part of trading fees as rewards. It\u2019s one of the primary sources of passive income for crypto investors. <\/p>\n\n\n\n
Staking is an alternative to the traditional Proof-of-Work (PoW) consensus mechanism Bitcoin uses. Recently, Ethereum also shifted to a Proof-of-Stake (PoS) consensus mechanism after the merge<\/a>.\u00a0<\/p>\n\n\n\n
Staking in decentralized finance is different from staking in a centralized exchange. DeFi staking requires more involvement throughout the process. Check out our in-depth guide on DeFi staking<\/a> to know more.<\/p>\n\n\n\n
DeFi Crypto Loans<\/strong><\/h3>\n\n\n
\n![\"DeFi](\"https:\/\/bitcoin.tax\/blog\/wp-content\/uploads\/2022\/12\/Defi-Crypto-Loans-1024x1024.png\")
<\/figure>\n<\/div>\n\n\nCrypto loans are the same as traditional loans. You deposit some cryptocurrencies as collateral and receive a loan of a certain amount. The only difference is instead of a banking institution manually overseeing the arrangement, it\u2019s automated with smart contracts.<\/p>\n\n\n\n
Crypto loans are also a great way to save more taxes. Here\u2019s how<\/a>. Some people use crypto loans for yield farming<\/a> or leveraged yield farming<\/a> (passive income strategies).\u00a0<\/p>\n\n\n\n
Some DeFi platforms that provide crypto loans are BlockFi, SpectroCoin, Nexo, etc. <\/p>\n\n\n\n
But what if you\u2019re on the side of the equation? With decentralized finance, you can lend loans as well. And in return, you\u2019ll receive interest in the form of rewards.\u00a0<\/p>\n\n\n\n
Stablecoins<\/strong><\/h3>\n\n\n
\n![\"Decentralized](\"https:\/\/bitcoin.tax\/blog\/wp-content\/uploads\/2022\/12\/Decentralized-Finance-Stablecoins-1024x1024.png\")
<\/figure>\n<\/div>\n\n\nWith the help of smart contracts, some people came up with the idea of stablecoins – coins with their value pegged to a fiat currency, gold or other commodities. It helped stabilize the price of the token. <\/p>\n\n\n\n
Now, you have coins like USDT pegged to the value of the US dollar, meaning 1 USDT will always be equal to 1 USD. This was a revolution for the entire crypto space.\u00a0<\/p>\n\n\n\n
Check out our in-depth guide on Stablecoins<\/a>.<\/p>\n\n\n\n
However, nothing is perfect. Even a minor error in the smart contract can cause an entire infrastructure of stablecoins, consequently, the entire DeFi space to collapse, which is exactly what happened in the Terra Crash<\/a>.\u00a0\u00a0<\/p>\n\n\n\n
And this brings us to the limitations of decentralized finance. <\/p>\n\n\n\n
Pros and Cons of DeFi<\/strong><\/h2>\n\n\n\n
As with any other technology, decentralized finance has limitations, drawbacks and risks associated with it as well. But whether the cons outweigh the pros is still up for debate.<\/p>\n\n\n\n
Pros<\/strong><\/h3>\n\n\n\n
- Permissionless access to everyone –<\/strong> there are no restrictions or gatekeeping on who can or can not use DeFi services. All you need is an internet connection and a crypto wallet to access the DeFi protocols.<\/li>
- Instant transactions – <\/strong>Regional and international transactions on Bitcoin\u2019s blockchain take around ten minutes, which is still faster than most traditional banks. On Ethereum\u2019s blockchain, the average transaction speed is 13-14 seconds. <\/strong><\/li>
- Open source – <\/strong>Most DeFi protocols and platforms are open source, meaning anyone can inspect the underlying code, point out flaws or use it as a framework to build something on top of it, allowing more innovation. <\/li>
- Decentralized –<\/strong> With DeFi, you enjoy all the benefits of decentralization, such as more control over your assets, anonymity, lack of restrictions, lack of intermediaries, etc. <\/li>
- Generate passive income – <\/strong>Decentralized finance was created to replace traditional financial institutions. But instead, it became a source of passive income for crypto investors and traders. <\/li><\/ul>\n\n\n\n
Cons<\/strong><\/h3>\n\n\n\n
- High risk of scams and hacks – <\/strong>Since decentralization lowers the barrier of entry and eliminates regulations and restrictions, it\u2019s easier for scammers to set up an exit scam and rug pulls<\/a>, which happens almost every day. Hacks come from flaws and loopholes within the code that hackers exploit.\u00a0<\/li>
- Difficult learning curve – <\/strong>This guide would help you understand DeFi better, but people with little understanding of the fundamentals – blockchain and cryptocurrency, may find DeFi too complex and hard to understand.\u00a0<\/li>
- Highly volatile –<\/strong> Crypto is a highly volatile asset, and so is DeFi. On a micro level, high volatility can lead you to lose money on staking, yield farming or liquidity pools. On a macro level, it can lead to the collapse of the entire market, as seen in the Terra Crash.\u00a0<\/li>
- Lack of regulations and government oversight – <\/strong>It may seem more like a pro than a con, but lack of regulations and government oversight exposes DeFi to more financial crimes, like money laundering, terrorist funding or small scams and hacks<\/a>, where the authorities have very little access to track down the culprits.\u00a0<\/li><\/ul>\n\n\n\n
Popular DeFi Platforms<\/strong><\/h2>\n\n\n\n
The following are some of the most popular (or unique) DeFi platforms that use the blockchain and smart contract technology to create something new and useful. <\/p>\n\n\n\n
- Compound<\/strong><\/a> – <\/strong>Compound is a platform where you can borrow or lend crypto as loans.\u00a0<\/li>
- Uniswap<\/strong><\/a> –<\/strong> Uniswap is a decentralized exchange that uses AMM and smart contracts to facilitate trading.\u00a0<\/li>
- Youholder<\/strong><\/a> –<\/strong> Youholder is a gaming platform that rewards you with crypto for winning. The more you win, the more you can play.\u00a0<\/strong><\/li>
- Nexo<\/strong><\/a> – <\/strong>Nexo is similar to Compound, as it\u2019s also a borrowing and lending platform. But there is a twist. It allows you to borrow using your friends and family as collateral.\u00a0<\/li>
- Decentraland<\/strong><\/a> – <\/strong>Decentraland is a 3D-virtual world platform where you can pretty much do anything.\u00a0<\/li><\/ul>\n\n\n\n
