The Future of DeFi: How Decentralized Finance Will Reshape Global Finance

What is DeFi? The Ultimate Beginner-Friendly Guide to Decentralized Finance

DeFi, or Decentralized Finance, is a major change in the way we use money and the way financial services are provided. Rather than having to rely on banks, brokers, or other traditional financial intermediaries, the DeFi system uses blockchain technology to provide an environment for creating financial services that operate automatically and also to provide transparency to these financial services.

The underlying premise of DeFi is that there are three primary components. First, there are smart contracts, or codes, that execute themselves when the conditions of the contract are met. Second, there are decentralized protocols for the operation of the DeFi system. Finally, DeFi operates on crypto tokens, which are digital representations of value or ownership.

Because of these three components, DeFi provides financial services that anyone can access without going through the bank for approval and without filling out any paperwork.

As an example of the above are lending platforms like Compound and Aave. These platforms are automated lending systems where you can lend cryptocurrency and earn interest or borrow cryptocurrency by providing collateral. In both cases, the process occurs without a loan officer's review of your application and without the bank holding your funds. The smart contract enables these transactions and enforces predetermined rules.

The foundation of traditional Finance is institutional trust. The basis of DeFi is code trust. Banks can change their contract terms, freeze your account, or not allow you to access the bank’s services. DeFi protocols are trusted to implement exactly what has been programmed for them without exception and to treat each person the same and not to arbitrarily prevent access.

As an example, to help beginners conceptualise this, think of a savings automation service that generates interest on funds deposited without requiring you to have a regular banking or checking account. You would deposit funds with the service; the service would lend your funds to other people through a transparent set of processes, and you would receive financial returns on those funds that would be provided directly to you without any third-party fees or hidden costs.

How DeFi Works: From Smart Contracts to Decentralized Protocols

It is not difficult to understand how DeFi works. It works in a straightforward manner through a streamlined workflow that eliminates the need for any human middlemen, known as gatekeepers, between the parties involved in a financial transaction.

To use a DeFi service, all that is needed is for a user to connect their digital asset's "wallet" (e.g., a wallet like MetaMask) to the DeFi platform they wish to use. This wallet acts as an individual's identity in the DeFi ecosystem; no usernames or passwords are required. Any time an individual would like to perform an action such as making a transaction, exchanging tokens, or receiving a loan, they do so through the application's platform.

This is the part of the workflow that becomes more interesting: rather than the transaction request being sent directly to a traditional employee at a bank to receive approval, the request now initiates a smart contract. Smart contracts are nothing more than lines of code existing on the blockchain that are preprogrammed to perform specific functions when the precondition(s) set in the code have been met or executed.

For example, if you wish to swap tokens on Uniswap, the smart contract will validate that you possess the tokens you would like to exchange, determine the value of the tokens being exchanged based on the liquidity of the Uniswap network, and accomplish your token swap immediately.

This system's automation is what makes it so great. No waiting on business hours, no approval processes, and no human who has the ability to deny your transaction based on arbitrary standards. The code will always execute exactly as stated in the order.

One thing that you do have to pay for is gas fees, which are essentially small payments to the network to cover the cost of processing a transaction. It's like getting a better experience by tipping someone who gives you quicker service. When there are many transactions on the network at once, gas fees increase; when the network isn't busy, they decrease.

An example of this is minting an NFT. With a click of a button, the smart contract will check for payment and create an NFT, transferring ownership to your wallet. This entire process is completed in seconds with no manual processing.

Types of DeFi: Key Categories Every Crypto Trader Must Know

The DeFi ecosystem encompasses a range of different financial products and services that address various requirements in the market. For example: 

DEXs (decentralized exchanges) provide individuals with the means to directly trade cryptocurrency with other traders. The two biggest decentralized exchanges are Uniswap and SushiSwap, which allow the trader to exchange cryptocurrency directly from their own wallet instead of through an intermediary such as a centralised exchange (CEX) where the company that operates the exchange stores the funds.

Automated lending and borrowing services such as Aave and Compound allow users to act as banks by depositing their crypto and earning interest or pledging it as collateral for loans against other digital assets. The interest rates on Aave and Compound are set via smart contracts based on supply and demand and do not require any human intervention or approval to adjust them.

Yield Aggregators like Yearn Finance provide users with a way to automatically invest and reinvest their funds in the most profitable yield-producing platforms and protocols available. These yield aggregators are effectively the same as having a financial advisor who works around the clock and optimizes investments without charging expensive management fees.

Users can trade various derivatives protocols such as futures and options via platforms such as dYdX, which is used primarily by professionals for hedging or speculation, thus allowing for exposure to an asset without direct ownership.

DeFi insurance products allow users to protect themselves against losses caused by a failed or hacked smart contract. Since transactions in DeFi cannot be reversed, having insurance allows customers to have some level of protection against loss.

In summary, the various categories that DeFi offers are aimed at catering for different types of users. New users entering the cryptocurrency market will generally start with a basic lending platform such as Aave in order to generate passive income. On the other hand, seasoned traders may leverage the tools and capabilities of a derivatives platform such as dYdX by taking high-risk positions. Overall, DeFi provides access to the full range of financial services available within the traditional financial markets without going through the cumbersome methods often associated with traditional finance.

Advantages of DeFi: Why Traders and Investors Should Care

Decentralized finance provides advantages that cannot be provided by Traditional finance. Additionally, these advantages are not only theory based, but they provide advantages that benefit actual individuals every day.

"True Decentralization" essentially means that no single entity or organization controls your funds. The bank can suspend your account, reject your transaction, and/or potentially go out of business. DeFi executes the transactions using computer "codes" and does not utilize any corporate discretion. Unless you, as the owner of funds, choose to transfer them, your funds do remain your funds.

"Security and Transparency" are inherent to the Model of DeFi. Every transaction that takes place is recorded on a Blockchain. Anyone can publicly audit the transaction code as well as view and verify the monetary flows of the Protocol. Traditional banks operate behind closed doors whereas DeFi operates transparently. 

"Global Access" makes financial services available to billions of individuals who do not currently have access to Traditional Banks (e.g. No Credit History, Residing in a Country with an Unstable National Currency, etc.). All you need is Internet Access and you can access Dollar Pegged Stablecoins.

Anyone can use DeFi for whatever reason, including non-technical people; therefore, having a blockchain wallet is your ticket to participating. 

In DeFi, token incentives give you ownership and voting rights in the governance of a protocol (platform). This is different from what would happen with a customer at a bank and how equity ownership is typically secured through a corporate structure.

Professionals have seen that with DeFi, the ability to reduce counter-party risk is another benefit as opposed to traditional finance. Instead of trusting a company to keep its promises (i.e., an institution), you are trusting mathematics, where the code will execute according to how it was programmed or intended to function.

Risks and Limitations of DeFi: What Every User Should Know

The risks associated with using DeFi should be understood to use DeFi safely and avoid costly mistakes.

High gas fees are a result of network congestion. When the Ethereum network is busy, the gas fee on a simple transaction could be $50 or more. As a result of high fees, small transactions are impractical, and users from developing countries that DeFi is supposed to help are unable to participate.

There are a number of serious risks associated with smart contract vulnerabilities. There are bugs in code, and bugs in financial code will cause stolen money. For example, hackers have hacked into DeFi protocols and taken hundreds of millions of dollars. Once funds are stolen, it is very difficult to recover them.

The user experience is poor for newcomers to DeFi. In order to know about gas fees, slippage, liquidity pools, and impermanent loss, one has to conduct research. Just one mistake clicking on a link can send money to the wrong address, which is irreversible.

The regulatory environment surrounding DeFi is uncertain and constantly changing. Government officials are still determining how to classify, regulate, and operate DeFi, and new laws could change the ability to access DeFi as well as the taxation of DeFi and the legality of certain DeFi activities.

Professionally, there are contract exploits, which happen when attackers locate a vulnerability in the smart contract code to access and/or drain funds; liquidity risk, which means that during times of volatility, it may be impossible to withdraw or access your funds, and problems can arise from bad data being sent to the smart contract from oracles, resulting in cascading problems.

For beginners, the biggest risk is simple: lose your private keys, lose your funds forever. There's no "forgot password" button, no customer service to call. You're the bank, which means you're responsible for security.

Global Use Cases of DeFi: Everyday Applications and Investment Opportunities

The rapid evolution of decentralized finance ("DeFi") from a speculative investment craze to everyday use is impressive. Today's DeFi platforms provide millions of users globally with practical solutions for jobs, trading, investing, and lending, as well as helping folks achieve financial freedom.

People can now trade tokens using decentralized exchanges (DEXs), which allow them to access multiple tokens without needing to use an exchange platform such as Coinbase or Kraken. Plus, because DEXs allow users to trade 24 hours a day, seven days a week, people can trade whenever they want without any restrictions imposed by centralized exchanges.

With lending and saving platforms in the DeFi space, borrowers can earn more than 5% on stablecoins, while banks traditionally only pay .05%. Therefore, when you lend money on a DeFi platform or savings bank, you effectively become your own bank and earn interest on the money you lend out.

DeFi also plays a role in games and game finance ("GameFi"). Blockchain has enabled play-to-earn games, allowing players (especially in developing nations) to turn gaming from an expense into a source of income.

The creator economy and non-fungible tokens (NFTs) provide a new way for creators, including artists, musicians, and filmmakers, to monetise their creations without having to deal with traditional record labels that take 90% of their earnings or galleries that take half of a piece's sale price. By selling directly to fans, creators maintain most of the revenue.

Sophisticated trading strategies that have previously only been available to institutional investors are now available to anyone using services such as dYdX. Platforms like Yearn Finance also optimize the return on savings across multiple DeFi protocols, similar to what a full-time portfolio manager would do.

Africa has limited access to traditional banking but offers access through DeFi on dollar-pegged savings accounts and payment services. People are using stablecoin to protect their assets from the declining value of the currency and send money home without paying high fees for international transfers.

The statistics back this up. Every day, DeFi transacts billions of dollars worth of trading activity. Across the globe, tens of thousands have already deposited money into lending protocols. This isn't something coming in the future. It's going on today.

How to Use DeFi Safely: Step-by-Step Guide for Beginners

To confidently enter DeFi, start with the right steps and have an understanding of the risks associated with them prior to using your money.

First, create a wallet with a reliable Wallet provider such as "MetaMask". As a browser extension, it can connect to different DeFi (decentralized finance) platforms and is the most common method. Please ensure you only download this from the "official MetaMask" web address for security reasons to avoid phishing attacks or downloading from fraudulent websites that could take your funds.

Your "seed phrase" is extremely important. Your seed phrase will help you recover your wallet if needed, similar to how an individual can recover access to their bank account. Your 12 to 24 word "seed phrase" should never be provided to any websites or apps, and should be stored securely (on paper) in a secure location where it cannot be stolen. If someone obtains your seed phrase, they will have possession of all your funds stored in that wallet.

Be careful when connecting your wallet to DeFi platforms. Always check the Web Addresses multiple times to confirm they're legitimate before connecting. There are fraudulent/luring phishing sites that look exactly like real sites, so don't ever connect your wallet or enter your seed phrase on any site unless you are certain it is the legitimate site. To avoid accidental typos or mistakes leading you to phishing sites, bookmark legitimate DeFi platforms.

Make sure you are aware of "Gas Fees" prior to making any transaction. Be sure to check the current "Network Congestion" along with the estimated gas fee(s) for the transaction being made, as some transactions might cost more in fees than the transaction itself is valued at. Timing is also important as gas fee rates and network congestion tend to decrease through the night hours.

Start testing with the smallest amounts possible before sending larger quantities. Before sending $10,000, send $10 first to make sure you understand how it works and that everything functions as expected. Mistakes are irreversible, practice with amounts you can afford to lose.

Helpful hints include setting your gas limit to avoid paying unreasonably high fees during periods of high activity, verifying contract addresses against official sources before sending any transactions to them, and using hardware wallets for sending large amounts of cryptocurrencies.

You should never share your seed phrase with anyone who claims to be providing customer service, as DeFi platforms will never ask for your seed phrase. If someone asks you for your seed phrase, they are trying to scam you.

Future Trends of DeFi: Why It Will Reshape Global Finance

DeFi has not yet reached its full potential. The evolution of DeFi will be drastic over the next few years, with many new features on DeFi platforms that will make the current platforms appear very basic by comparison. The introduction of decentralized derivatives such as Complex Options Strategies and Synthetic Assets will bring the same level of sophistication found on Wall Street to everyone who has an internet connection.

Tokenizing real-world assets will create a new frontier for DeFi. Real estate, stocks, bonds and commodities will be traded on a 24/7 basis on Blockchain Technology and fractional ownership will allow retail investors to own fractions of asset classes that are currently only available to large institutions.

Web3 identity systems will address the DeFi user's experience issue of managing multiple wallets and seed phrases by creating a single login experience for accessing DeFi's infrastructure while preserving user privacy.

The impact on the Financial System globally will be immense. Cross-border payments that take several days and charge hundreds of dollars in fees will be settled instantly for a fraction of a cent. The ability of anyone to access Investment Opportunities that have been available only to Wealthy American Investors will create a Global Opportunity for Everyone. As a result of these advancements, Financial Services will compete on the basis of the quality of services provided and no longer based on geographical monopoly. 

Technology improvements are currently addressing some of these limitations.  The creation of Layer 2 platforms and projects has led to an enormous decline in the "Gas Fees" associated with using the Ethereum Blockchain.  The development of user-friendly Wallets makes it easier for people to use the DeFi ecosystem.  Security audits are becoming more robust and allow companies and projects to discover vulnerabilities in their code before the code has been exploited.

The amount of money held by Decentralized Finance (DeFi) in vaults (TVL) has gone from being practically 0 to beyond 100 billion dollars within several years. Users are now having more success than ever before in utilizing DeFi protocols due to improvements in interface design along with the growth of use cases being implemented into DeFi protocols. This is not just marketing hype, but rather signifies that we are witnessing a significant paradigm change within the structure of financial systems.
