About DeFi

DeFi stands for decentralized finance, a blockchain-based decentralized financial platform that does not depend on financial institutions or banks.

DeFi uses cryptocurrency, blockchain, and smart contracts in its operating system. Smart contracts play essential roles in managing all activities in DeFi, such as controlling the token prices, interest rates, service fees, approving transactions, and other activities.

Data from DeFiLlama on November 15, 2022, the funds in the entire DeFi ecosystem of various blockchains reach 43.78 billion US dollars. As you can see, in December 2021, the TVL (Total Value Locked) once hit an all-time high of 181.32 billion US dollars!

Why Do We Use DeFi?

DeFi basically provides financial services that most people are already familiar with. The distinction is that DeFi offers transparency and higher return opportunity to its users. Furthermore, no institution has control over financial services in DeFi.

The advantage of DeFi compared to TradFi systems is that anyone can access DeFi financial services online anytime, 24/7. In addition, users can execute payment transactions within minutes and manage their crypto or self-custody.

DeFi eases its users to access financial services. Anyone can use DeFi through decentralized applications (DApps) or DeFi applications. Users do not need to do a KYC (Know Your Customer) to access DApss. It is different from the TradFi system. TradFi requires personal data of prospective customers to open savings accounts or borrow funds, such as e-mail, id card, photo, and other data.

Decentralized applications (Dapps) are similar to regular applications on your smarphone or PC. The difference is that DApps are built with blockchain technology.

How to Use DeFi Applications?

Select Blockchain Network

Ethereum is a blockchain that pioneers smart contracts; most DeFi applications run on the Ethereum blockchain. However, currently there are a lot of new challengers to Ethereum, namely Binance Smart Chain, Solana, Avalanche and other blockchains.

Some blockchains have advantages such as fast transaction processing, low gas fees, and a mature DeFi ecosystem. So, you need to consider the network you want to use before choosing the DeFi application. In this article, we will guide you on how to use DeFi applications on the Ethereum network.

Create Crypto Wallets

First, you need to connect crypto wallets to access DeFi applications. Several wallets you can choose are Metamask, Trustwallet, Phantom, and other wallets. Metamask is an Ethereum wallet that supports multiple blockchain networks and can be installed as a wallet extension in your browser. Metamask also provides safe and efficient access to DeFi applications.

The wallet extension enables users to jump right into DeFi applications and manage money in the browser. Here’s how to create a Metamask account.

Buy Cryptocurrencies

Before using a decentralized application, you must have a certain number of blockchain native coins (e.g., ETH) or blockchain standard tokens (e.g., ERC-20 tokens) in your wallet.

Why you need to provide cryptocurrency in your wallet? Because you have to pay gas fee in cryptocurrency. Gas fee in Ethereum refers to the additional fee required to execute a smart contract or transaction on the blockchain network.

You can buy cryptocurrency on centralized exchange like Pintu. After that, you can send it to your wallet. Here’s how to send crypto assets from Pintu.

Here are some of the DeFi financial services and DApps that are currently available. You can use them to earn rewards as passive income.

1. Decentralized exchange (DEX)

On DEX, there are several financial services such as cryptocurrrency swapping, yield farming, staking, etc.

If you want to earn rewards in Farming, you can be a liquidity provider (lp). You can deposit two crypto assets into the liquidity pool to get liquidity pool tokens. And then, you can deposit them into the Farming pool to earn the native DEX tokens such as UNI, SUSHI, CRV, and others.

Another feature you can use on DEX to get passive income is staking. In the staking feature, you can lock several tokens to get rewards in the form of other tokens.

In this section, we will give you a tutorial how stake SUSHI token on Sushiswap. Sushiswap allows you to stake SUSHI tokens to get xSUSHI tokens. Here’s how to do staking on Sushiswap.

Step 3

  • Staking successful!
  • You can see the number of xSUSHI has increased to 16.1.
  • The number of xSUSHI will increase daily, so you can get passive income through staking SUSHI.

2. Lending and Borrowing

Like deposit money and loan service in the bank, DeFi also has lending and borrowing financial services in crypto assets. Users can lock crypto assets in a liquidity pool and earn rewards as a lender.

Users can also borrow crypto assets to leverage trading (trading with borrowed capital). To borrow a crypto asset, users must deposit a crypto asset as collateral to secure the loan from the lender. Each crypto asset has a different LTV (Loan to Value) percentage.

LTV (Loan to Value) defines the maximum amount of assets that can be borrowed with specific collateral. For example, the LTV of the crypto asset ETH is 80%. At LTV=80%, for every 1 ETH worth of collateral, borrowers can borrow 0.8 ETH worth of the corresponding currency.

One of the DApps that provides lending and borrowing services on Ethereum is Aave. Here’s how to borrow crypto assets on Aave.

Step 4

  • Click Confirm.
  • Success! You managed to borrow 35 ENJ.

After borrowing ENJ with DAI as collateral, you now have 35 ENJ in your Metamask wallet. You can trade ENJ tokens or deposit them in other DApps to generate interest. You can also use an aggregator application to see the highest percentage of interest on various DApps.

3. Aggregator

A DeFi aggregator is a platform that collects price comparisons from different DEXs. It helps users maximize profits, save users time, as well as mitigate high slippage.

To minimize the slippage, users may split their crypto assets into smaller parts and route them onto several DEXs. With DeFi agregator, users can automatically split their large crypto assets into smaller parts. Then, the DeFi agregator routes them to the relevant DEXs for the best exceution price. DeFi aggregators on Ethereum are 1Inch, Matcha, Zapper, etc.

Here is an example of swapping crypto assets using a DeFi aggregator on 1Inch to get the best price.

Step 3

  • Enter the amount of ETH you want to exchange.
  • Then click Swap.

After a successful swap, you will have USDT in your wallet.

How to Identify a Good DeFi Project?

After knowing what services you can use in DeFi and how to use DeFi applications, you can determine which DApps that are right for you. Here are some steps you can take before choosing a DeFi app.

  • Choose the blockchain. Some blockchains have robust DeFi ecosystems, such as Ethereum, Binance Coin, Solana, Avalanche and others. Each blockchain also implements different amount of fee to confirm transactions. So, before deciding to use services on DeFi, it’s important to choose a network.
  • Check the TVL (Total Value Locked) or the number of funds available on the DApps to see asset liquidity. You can also check the number of assets owned by DApss through the wallet address in the block explorer.
  • In the staking feature, you can choose the amount of APR that suits you. The higher the APR number, the more profit you will get. However, the risks are also higher.
  • Active community is essential. You can check a DeFi project’s Telegram, Twitter, and Discord to assess the community sentiment towards the project.
  • You can find out who the developers are and how a DApp project will sustain in the future through the available whitepapers and roadmaps.
  • Uniswap

Uniswap is one of the most popular decentralized exchanges (DEX) on the Ethereum network. This platform works using Automated Market Maker (AMM) to run its protocol.

On Uniswap, you can exchange crypto assets. Furthermore, you can also become a liquidity provider by locking crypto assets in liquidity pools.

  • Synthetix

Synthetix is a DEX that provides synthetic assets. It creates synthetic assets known as Synths in tokens that resemble the original assets. A primary goal of Synthetix is to give crypto investors exposure to reach an asset that is not on the blockchain, for example, gold and silver. In short, Synths are a combination of cryptocurrencies with derivative assets.

Assets on Synthetix are cryptocurrencies, commodities (gold, silver, petroleum), fiat currencies, Indexes (NIKKEI, CEX, FTSE), and stocks (TSLA). These synthetic assets (Synths) will become sTokens, such as sBTC, sXAU, sUSD, sJPY and so on.

On this platform users can buy, stake, and borrow synthetic assets.

The Future of DeFi

DeFi is touted as the future of the banking. DeFi thrives to overhaul traditional financial systems. But right now, DeFi is still considered as a high-risk financial service.

Nonetheless, several major institutions have direct exposure to crypto assets and already experimenting with DeFi. Goldman Sachs, Barclays, Banco Santander, and Itau Unibanco are among the organisations that have entered the DeFi ecosystem in the past two years. On November 2, 2022, JP Morgan made transactions using the DeFi application, Aave, on the public blockchain for the first time.

However, it is important to remember that DeFi projects are still in their early stages and are fraught with hazards such as smart contract errors, rug pull, and blockchain network difficulties.

In the future, DeFi will be developed more by various blockchains and cooperate with centralized financial institutions. Some US economists have also stated that regulation is critical to DeFi’s sustainability.
