Decentralized finance, or DeFi for short, is a growing ecosystem of financial protocols built on Ethereum. From lending and borrowing platforms to stablecoins and tokenized BTC, DeFi applications are changing the way we think about financial products and services. In this post, we’ll explore what DeFi is and how it’s changing the crypto landscape.

Decentralized finance—often called DeFi—refers to the shift from traditional, centralized financial systems to peer-to-peer finance enabled by decentralized technologies built on the Ethereum blockchain. From lending and borrowing platforms to stablecoins and tokenized BTC, the DeFi ecosystem has launched an expansive network of integrated protocols that are growing in usage and value. Now with over $13 billion worth of value locked in Ethereum smart contracts, decentralized finance has emerged as the most active sector in the blockchain space, with a wide range of use cases for individuals, developers, and institutions.
What is DeFi?
Decentralized finance—often called “DeFi”—refers to the shift from traditional, centralized financial systems (like banks) to peer-to-peer finance enabled by decentralized technologies built on the Ethereum blockchain. From lending and borrowing platforms to stablecoins and tokenized BTC, the DeFi ecosystem has launched an expansive network of integrated protocols and financial instruments. Now with over $13 billion worth of value locked in Ethereum smart contracts, decentralized finance has emerged as the most active sector in the blockchain space, with a wide range of use cases for individuals, developers, and institutions.
Decentralized exchanges (DEXs) are powered by Ethereum smart contracts and designed to offer users a completely decentralized way to trade cryptocurrency. DEXs don’t require KYC verification or registration, so they’re ideal for users who value privacy.
Some popular DEXs include Uniswap, Kyber Network, Bancor, and AirSwap. These exchanges allow users to trade directly from their wallets without having to first deposit their funds into a centralized exchange.
With a DEX, you retain control of your private keys at all times. This means that you are the only one who has access to your funds, and no one can freeze or seize them. DEXs are also generally more resistant to hacks than centralized exchanges, since there is no central point of attack.
If you’re looking for a completely decentralized way to trade cryptocurrency, then a DEX is the exchange for you.
Lending platforms: Lending platforms allow users to lock up their assets as collateral in order to borrow assets from other users. The most popular lending platform is MakerDAO, which allows users to collateralize ETH and stability coins such as DAI. Once the user has paid back the loan plus interest, they can then withdraw their protocol-backed coins.
In the world of cryptocurrency, the value of a digital asset can be highly volatile. That’s why some projects have been exploring ways to create “stablecoins”—cryptocurrencies that are pegged to a stable asset, such as the US dollar.
One popular type of stablecoin is a “reserve-backed” stablecoin, which is backed by a reserve of assets (usually fiat currency or cryptocurrency) that can be used to stabilize the price. Another popular type of stablecoin is a “collateralized” stablecoin, which is backed by collateral (usually another cryptocurrency) that can be used to stabilize the price.
There are many different projects working on stablecoins, and each has its own strengths and weaknesses. Some of the most popular stablecoins include:
-Tether (USDT): Tether is a reserve-backed stablecoin that is backed by US dollars held in reserve. Tether is one of the most popular stablecoins in use today, with a market capitalization of over $4 billion.
-USD Coin (USDC): USD Coin is a collateralized stablecoin that is backed by US dollars held in reserve. USD Coin is issued by the CENTRE Consortium, a joint venture between Circle and Coinbase. USD Coin has a market capitalization of over $1 billion.
-Paxos Standard Token (PAX): Paxos Standard Token is a collateralized stablecoin that is backed by US dollars held in reserve. Paxos Standard Token is issued by Paxos Trust Company, LLC, a New York chartered trust company. PAX has a market capitalization of over $300 million.
-TrueUSD (TUSD): TrueUSD is a collateralized stablecoin that is pegged to the US dollar. TrueUSD is issued by TrustToken, Inc., an American company. TUSD has a market capitalization of over $200 million.
Other DeFi protocols
In addition to the protocols mentioned above, there are a number of other protocols that fall under the DeFi umbrella. These include but are not limited to:
-Compound: a protocol that allows users to earn interest on their crypto deposits or take out loans using their crypto as collateral.
– Kyber Network: an on-chain liquidity protocol that allows users to seamlessly swap between different cryptocurrencies.
– Aave: a protocol that allows users to earn interest on their deposits or take out loans using their crypto as collateral.
– Bancor: a protocol that allows users to convert between different cryptocurrencies without the need for a centralized exchange.
– Maker: a protocol that allows users to collateralize their crypto assets in order to generate Dai, a stablecoin that is pegged to the US dollar.
Benefits of DeFi
Decentralized finance, often called DeFi, is a growing ecosystem of financial protocols built on Ethereum. From lending and borrowing platforms to stablecoins and tokenized BTC, DeFi applications are automating financial services that have traditionally been provided by centralised institutions. Now, let’s look into the benefits of DeFi.
The decentralized nature of DeFi protocols means that they are not subject to the same regulatory risk as traditional financial institutions. This increased security is one of the main benefits of DeFi protocols. By using a decentralized infrastructure, DeFi protocols are able to offer a higher level of security to their users.
When you lend or borrow money through a traditional financial institution, that loan is often bundled with other loans and then sold as a security to investors. The terms of the loan are often opaque, and it can be difficult to track where your money is going.
With DeFi, loans are fully transparent. You can see on the blockchain exactly how much money has been lent out, at what interest rate, and to whom. This level of transparency is not possible with traditional financial institutions.
When you use a traditional financial system, there are numerous middlemen involved in any given transaction. Not only does this slow things down, but it also drives up the cost of completing a transaction. For example, if you’re sending money abroad, you’ll need to pay fees to your bank, the receiving bank, and possibly a foreign exchange provider.
With DeFi applications, there are no middlemen because the transactions are completed on the blockchain. This not only reduces the time it takes to complete a transaction but also eliminates the need to pay expensive fees.
Risks of DeFi
Decentralized finance protocols have seen a lot of growth in 2020. However, they still come with a lot of risks. In this article, we will discuss the risks of DeFi protocols.
Lack of regulation
One of the concerns that have been raised about the DeFi space is the lack of regulation. Because crypto assets are not regulated in most jurisdictions, this means that there is no regulatory oversight of the activities taking place in the DeFi space. This could lead to a number of problems, including fraudulent activities and money laundering.
Smart contract vulnerabilities
One of the primary risks associated with DeFi platforms is the vulnerability of smart contracts. A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. Smart contracts are what allow for the transfer of assets on a decentralized network without the need for a third party or intermediary.
While smart contracts offer a number of advantages, they are also susceptible to hacks and exploits. In July of 2017, the Parity Wallet hack resulted in the loss of over $30 million worth of Ethereum (ETH). The hack occurred due to a vulnerability in Parity’s smart contract code that allowed attackers to gain control of wallets that were created after July 20th.
Similarly, in June of 2018, another exploit resulted in the loss of over $13 million worth of Ethereum (ETH) from vulnerable smart contracts. These examples illustrate how costly mistakes in smart contract code can be and serve as a reminder that platform creators need to carefully audit their code to prevent vulnerabilities.
One of the key risks associated with DeFi is liquidity risk. This is the risk that you will not be able to find buyers or sellers for the assets you want to trade, or that the prices you want to trade at are not available. This can lead to delays in getting your money out of a position, or even getting stuck in a position altogether.
There are several factors that can contribute to liquidity risk in the DeFi space. First, many DeFi protocols are still in their early stages and have not yet been battle-tested by large numbers of users. This means that there is a lack of data about how these protocols will perform under stress, which can make it difficult for investors to assess their risk.
Another factor is that many DeFi protocols are built on top of Ethereum, which itself has scalability issues. This means that when demand for a particular protocol increases, the underlying Ethereum network may become congested, leading to delays in transactions. This congestion can also lead to higher transaction fees, as users compete for scarce space on the blockchain.
Finally, some DeFi protocols require users to deposit collateral in order to use them. If the value of the collateral falls below a certain threshold (known as a “liquidation price”), then the user may be forced to sell their position at an unfavorable price in order to avoid losing their collateral entirely. This can lead to sudden and sharp declines in asset prices, which can adversely affect investors’ portfolios.
In conclusion, DeFi is a revolutionary way to use cryptocurrencies that allows users to do things that were not possible before. By lending and borrowing cryptocurrency assets, DeFi can help you get more from your crypto portfolio. In addition, DeFi can help you hedge against risk and earn interest on your digital assets. With so many benefits, it’s no wonder that DeFi is gaining popularity in the cryptocurrency community.
