    What Is DeFi In Crypto & Is It The Future?

    Integrating blockchain technology with real-world applications is a key step toward mass adoption and acceptance by Governments and financial institutions. Decentralized Finance or "DeFi" is transforming the financial sector by limiting third parties' impact on digital transactions by removing the middle-man. This article will explain what DeFi is, how it works, the pros & cons of DeFi products and whether this new technology can challenge established financial systems.

    What Does DeFi Stand For?

    DeFi stands for a decentralized financial system that uses the blockchain network for customers to access financial products and services without an intermediary such as central banks and institutions. DeFi services first launched on the Ethereum (ETH) blockchain, an open-source smart contract platform to facilitate decentralized applications. Ethereum provided a suitable platform for DeFi to succeed with developers widely adopting the protocol as a trustworthy platform to build financial services to disrupt the traditional sector.

    Why Is Defi Important?

    The importance of DeFi is centered around using the blockchain network which provides a means for secure and verifiable transactions without a trusted party. Bitcoin kickstarted the first iteration of decentralized finance in 2008 which created a decentralized environment for peer-to-peer online transactions.

    DeFi shapes as a better alternative to traditional finance without intermediaries to offer a trust-less, cheaper and safer system for transacting value. Secondly, DeFi offers the ability to expand beyond the financial transaction to build an innovative and dynamic world of real-world applications that include decentralized exchanges, stablecoins, lending and borrowing platforms and yield farming.

    Why is DeFi Popular?

    DeFi applications allow individuals to exchange, lend, borrow, and trade while remaining in complete control of all digital assets. Thanks to smart contracts and the blockchain, all third parties are removed from the process. Applications are available to anyone with a cryptocurrency wallet and services are far cheaper than traditional finance. There are also multiple opportunities to earn yields that far outpace those offered by the traditional banking sector.

    What Is DeFi Used For?

    DeFi is used to access blockchain-based financial services, meaning cryptocurrency owners can borrow, lend, earn interest or perpetual trading without the need for a third party. The total value locked in DeFi products exceeds $100 billion across all DeFi-supported networks. While lending and borrowing are part of the decentralized finance functionality, individuals can transact tokens through leading decentralized exchanges or DEX platforms.

    Decentralized exchanges differ from centralized crypto exchanges because they allow users to control their assets while disregarding broker and market maker fees. For example, on Uniswap, users can transact ERC-20 tokens without paying any exchange fees. The costs involved are limited to Ethereum network fees which are paid to miners on the network.

    In short, DeFi is used for a new wave of services that incentivizes asset owners to provide liquidity, generate passive income and contribute to the growth of an emerging financial market.

    What Are The Pros/Cons of DeFi?

    The benefits of DeFi extend beyond an alternative to the existing financial systems. The pros of adopting and regulating DeFi will provide basic banking and financial services to all individuals using secure, transparent and immutable transactions without a middleman. On the other hand, there are negatives such as failed projects, poor scalability and little consumer protection without Government regulations.

    DeFi Pros:
    • Permission-less system without reliance on corporations and institutions
    • A positive shift in traditional finance that will encourage innovation
    • Access to financial services for all individuals
    • Secure, transparent and immutable transactions
    • Faster transactions worldwide with lower fees
    • Higher interest rates compared to traditional financial products
    DeFi Cons:
    • Regulatory concerns from Governments around the world
    • Individuals are responsible and accountable for their assets without a central entity (e.g. bank)
    • Learning for individuals that want to participate in the technology
    • Fears and uncertainty over the protocols security
    • Lack of interoperability and scalability slows market adoption

    How Does DeFi Work?

    DeFi systems use a decentralized network where individuals can obtain access to financial products and services using 'smart contracts'. A key distinction of how decentralized finance works is the absence of a middle-man or central authority. Decentralized exchanges allow people to buy and sell between with each other using immutable smart-contracts.

    In a way, the programmed nature of each smart contract replaces the traditional financial institution. The digital contract is fully transparent and can be verified on an open public ledger, however, does not contain any personal information. For DeFi to be successful, the smart contracts must operate on a decentralized blockchain infrastructure. The most popular DeFi networks are Ethereum, Solana and Tron.

    A real-world application of DeFi is lending and borrowing platforms which have a similar process to traditional finance. A person that wants to borrow crypto can obtain a loan by providing a small amount of collateral. The benefit is to access liquidity without selling their digital assets. On the other hand, a person that lends their assets to provide liquidity for the loan will earn interest on their crypto in return. There are a number of providers that facilitate DeFi loans and interest payments such as BlockFi, Nexo and Celsius.

    How Do I Make Money With DeFi?

    After buying Ethereum, there are several applications and products that can be leveraged by investors to earn additional yield. The most common ways to make money with DeFi is through staking, liquidity farming, yield farming, and lending through crypto savings accounts.

    • Staking: Most DeFi platforms and protocols use PoS as their consensus mechanisms; therefore, the network rewards users that stake tokens for validation. In short, users have to lock up the protocol's native token for a certain period and receive interest that is paid out in the platform's native token. For example, staking Cardano has an estimated reward of 5.65% at the time of writing.
    • Liquidity Farming: Swaps between tokens on a decentralized exchange like Uniswap use liquidity providers. In DeFi, liquidity providers are users who add their token pairings to the liquidity pool. As a result, users who add their tokens are rewarded with a percentage fee - 0.3% from all swaps based on the proportion of their total share in the pool.
    • Yield Farming: Is is similar to the concept of staking. While tokens are added into the liquidity pool, the same tokens can be added to farms that create and distribute the farmed tokens. To keep things simple, Yield Farming is riskier than staking because protocol owners can obtain much easier access to the farms as DeFi farmers are always seeking farms with the best yields. For more information, read our guide on yield farming and how it works.
    • Lending: Users can lock up their tokens in smart contracts and use them to allow other users to borrow them in exchange for added interest. The benefit is that tokens are locked into contracts, and failure from borrowers to pay does not affect the lender's total assets.

    Are There Risks With DeFi?

    Every investment presents both opportunities and risks that largely depend on the type of strategy investors choose, the protocol or platform invested in and the level of knowledge and expertise. Investing in DeFi involves a similar risk to traditional markets but there are additional considerations. These include technical issues, project failures, regulations and hackers.

    • Technology issues. Decentralized finance protocols are a relatively new technology. The success of the DeFi protocol is 100% reliant on the software programmers and coders that have developed the smart contracts. Vulnerabilities in smart contracts can be exploited by bad actors and hackers. A relevant example is the DeFi platform BadgerDAO which was compromised resulting in a hack of $120 million in stolen crypto assets from investors' wallets.
    • Project failure (rug pulls). DeFi platforms, services and products are reliant on individuals to develop the systems to facilitate ongoing operation. In a way, these platforms are not entirely 100% decentralized as a degree of trust is placed on the developers behind the project. There have been examples where the owner of a DeFi project has blind-sighted the community and sold his tokens. For example, in 2020 the creator of the SushiSwap network sold $13 million worth of SUSHI tokens which collapsed the price.
    • Lack of regulatory oversight. DeFi products are not fully regulated in many jurisdictions at the time of writing. This presents an unknown for investors that can benefit the well-informed at the expense of smaller investors that lack expertise and knowledge. Furthermore, projects may not adhere to strict internal controls to protect investors from other risks.

    Is DeFi Regulated?

    DeFi is an innovative technology that is moving at a faster pace than laws and regulations. The various innovative products and services are technologically complex and may not be a perfect fit under current financial regulations in many countries. Within the United States, DeFi products are currently viewed under the lens of existing securities law. The SEC issued a statement that DeFi participants, activities and assets fall within the SEC’s jurisdiction.

    However, as record hacks in the DeFi space continue to make headlines, the chances of regulators stepping in to protect users' investment appear likely. This could set a trend globally for Governments' to regulate DeFi services that are gaining widespread popularity as an alternate system to traditional finance.

    Are DeFi Coins A Good Investment?

    Reputable DeFi coins can potentially be a good investment for passive income as long as the underlining asset price does not depreciate more than the annual yield. The tokenomics of every project must be considered to evaluate if token inflation presents a risk in the future, leading to lower prices as more tokens are flooding the market.

    Tokens and projects that provide essential operations such as price feeds, liquidity fees, or subgraph indexes are generally perceived to have more value than native tokens with no utility in the ecosystem.

    Conclusion

    As decentralized systems continue to evolve, there will be more incentives for individuals without access to traditional banking to use DeFi products and services. With over a 100 Billion market invested at the time of writing, it is a clear sign that DeFi is a way of the future. Therefore, it is crucial that ongoing dialogue between DeFi participants and Governments to encourage greater adoption. This will also contribute to closing the gap between financial innovation and regulation.
