Decentralized Finance (DeFi)

What is DeFi?

Imagine a financial ecosystem where one can access and use services directly without requiring any central authority—a bank or other financial institution. DeFi empowers market players to use financial and banking services in a peer-to-peer manner through decentralized applications specifically built on blockchain protocols.

DeFi, or Decentralized Finance, refers to banking and financial activities entirely based on the blockchain—the same way Bitcoin is. Where traditional finance is controlled by banks, DeFi strives to further open the financial system through decentralization.

Here are some of the financial services offered by DeFi:

• Borrow and Lend: DeFi platforms connect borrowers directly with lenders. This innovation may also mean loans reach the borrower with a reduced fee and can enable interest from their cryptocurrencies, which a lender could otherwise derive, to be higher.
• Trade Cryptocurrencies: One can trade peer-to-peer in cryptocurrencies through DEXs with high control and transparency compared to traditional exchanges.
• Earn Interest: DeFi platforms offer interest, also known as yield, on staked cryptocurrency. This may lead to passive income, becoming attractive to those looking to make better yields on their digital assets.

How Does DeFi Work?

DeFi can be boiled down to financial services without gatekeepers or centralized financial agents such as banks. 

Here's how DeFi brings finance directly to users:

• Decentralized Applications (dApps): dApps help power a wide array of services related to DeFi on the blockchain, from lending and borrowing to trading.
• Smart Contracts: Self-executing agreements, written into the blockchain code, where, upon fulfillment of the conditions specified in the smart contract—like returning a loan—the next step gets executed automatically, without the need for any intermediary.
• Crypto Wallets: Digital wallets that keep your cryptocurrencies and allow you to connect to DeFi dApps. They are a necessary tool to interact with the DeFi ecosystem.

What Are the Benefits of DeFi?

By employing blockchain technology, DeFi distinguishes itself from any central institution like a bank, making it an open and inclusive financial system. It involves several benefits for the user, as listed below:

• Transparency and Security: All DeFi transactions happen on-chain, making them transparent and immutable. Users can trace their assets and transactions with full confidence.
• Increased Financial Inclusion: DeFi removes many barriers to entry. Anyone who has an internet connection can access financial services such as borrowing, lending, and investing from any part of the world, regardless of location or traditional banking history.
• Higher Returns Potential: Most lending, investment, or yield farming facilities offered by DeFi platforms are considerably competitive. They offer interest rates often more attractive than those offered by traditional institutions. This could help users earn more from their assets.
• Control Over Your Assets: With DeFi, one holds digital assets in a crypto wallet. This means you will have full ownership and control over your financial decisions. In addition, DeFi transactions could be faster and much cheaper compared to traditional financial systems due to fewer intermediaries.
• Innovation and Experimentation: DeFi presents a space for innovation and experimentation in the delivery of financial services. Innovation is a core tenet of DeFi, as new applications and protocols are constantly being added to the space, giving users possibilities to deploy their capital in novel ways.

While DeFi offers exciting possibilities, it's important to be aware of the associated risks, such as market volatility and potential scams. It's crucial to do your research before engaging in any DeFi activities.

What are the Risks Involved in DeFi?

DeFi has opened a new chapter in finance. But like any other venture, it comes with risks. Here is a breakdown of some key factors to consider:

• Volatility: DeFi markets are extremely volatile, which means that the value of any investment is subject to extreme price action fluctuations. Unlike traditional financial products, DeFi assets might not have a clearly compounded short- or long-term record, limiting an investor’s ability to predict its future performance.
• Smart Contract Bugs: The functioning and operation of DeFi applications are realized through smart contracts. However, if such contracts are not perfectly coded, they may have vulnerabilities. Hackers can exploit this vulnerability to drain the protocol’s funds.
• Security Risks: DeFi platforms may be susceptible to cyber-attacks. Like many centralized institutions with big security apparatuses, some of the DeFi platforms have underdeveloped security protocols.
• Lack of Regulation: Given the novelty of the DeFi industry, there remains much work to do regarding regulatory frameworks on a global scale. However, there is an increasing amount of regulation being applied to DeFi and the blockchain industry as a whole.
• Complexity: DeFi is an extremely layered system. Understanding staking, lending protocols, and decentralized exchanges requires research and technical knowledge.
• Potential Loss of Access: Unlike traditional bank accounts, DeFi requires users to manage their private keys. Losing these may mean permanent loss of access to your DeFi holdings.
• Scams: Beware of fraudulent projects or unrealistically promising investment schemes. Never invest without doing your own research.

How Can I Get Started with DeFi?  

Here is a roadmap to get you going with the first steps: 

• Get Familiar with the Basics: Decentralized Applications (dApps) operate on the blockchain. Unlike traditional finance, there is no central bank involved.
• Set up your wallet: Think of it as a gateway into DeFi. You need to have a crypto wallet that can support DeFi apps and store your cryptocurrencies. These include Rabby, MetaMask, and Coinbase Wallet.
• Fund Your Wallet: Before using DeFi, you will need to top up your wallet with some cryptocurrency. You can buy Ethereum or another cryptocurrency from Coinbase and then send it to your non-custodial wallet for DeFi use.

DeFi provides a range of financial services that users can access directly without the need for centralized institutions or middlemen. Here is a staple option users can use in the world of DeFi:

• DEXs: Trade cryptocurrencies with other users directly and possibly at lower fees and greater control over traditional exchanges. 
  • Earn Interest: "Stake" or "lend" your crypto assets on DeFi platforms to earn interest. 
  • Borrow Crypto: Get crypto loans from other users on DeFi platforms, which are potentially more flexible than traditional loans.

There are more complex protocols offering vault strategies, asset collaterals, and other forms of financial products. We will cover these in-length in another article.

Start small, and research well—DeFi is new and developing. Read reviews, know the risks, and always deal with reputable platforms.

Is DeFi the Future of Finance?

DeFi is changing how we manage our finances and interact with the financial markets. DeFi allows this by leveraging blockchain and its innovations. It removes the middleman by putting users in a situation where they can interact with each other directly. This will allow:

• More Access: DeFi opens financial services to a large group of people by circumventing the limitations of traditional institutions.
• Increased Transparency: All transactions that occur on a blockchain are public and verifiable, hence building trust and security.
• Higher Efficiency: Because DeFi does not have any intermediaries, it makes transactions easier and requires fewer fees.

Through DeFi platforms, users can:

• Lend and Borrow Cryptocurrencies: No bank is needed for loaners, which may allow you to earn interest off your assets and access liquidity without selling the underlying asset.
• Trade Digital Assets: This involves peer-to-peer trading of cryptocurrencies in decentralized exchanges, which gives more control than traditional exchanges sometimes do.
• Earn Interest on Your Crypto Holdings: DeFi allows users to "stake" or lend their crypto to earn yield or interest.

However, DeFi technology remains in its early days. Here are some things that have to be considered:

• Volatility: The cryptocurrency market itself can be very unpredictable, and DeFi projects are risky.
• Complexities: DeFi has a learning curve. Always do your own research and due diligence.
• Scams: This holds true for DeFi as well. Be cautious and only invest in reputable projects.

DeFi reshapes the financial landscape into an open, accessible, and transparent model of financial services. It empowers people to take charge of their finances and takes out the middlemen. However, it is not without risk. Users should carry out their own due diligence before assessing whether or not to use a DeFi app. As the ecosystem matures and regulatory frameworks evolve, DeFi is well-positioned to be one of the cornerstones of the global financial system.
