What is DeFi? Essential knowledge for new investors

DeFi, short for Decentralized Finance, is a decentralized financial system built on public blockchains such as Ethereum, Binance Smart Chain, and Polkadot. Unlike traditional finance, DeFi does not require the intervention of intermediaries like banks, insurance companies, or other financial institutions.

Instead, all transactions and financial activities are conducted through smart contracts.

How DeFi works?


DeFi operates based on blockchain technology and smart contracts. Smart contracts are programs that automate financial transactions and their associated conditions. Once the conditions are met, the contract automatically executes the transaction without human intervention.

Main components of DeFi

🌳Stablecoins: These are cryptocurrencies designed to maintain a stable value relative to a specific asset, usually USD. Examples include USDT, USDC, and DAI.

🌳Decentralized Exchanges (DEX): Exchanges like Uniswap, SushiSwap, and PancakeSwap allow users to trade cryptocurrencies without intermediaries.

🌳Lending and Borrowing Platforms: Platforms like Aave, Compound, and MakerDAO allow users to lend and borrow cryptocurrencies in an automated and decentralized manner.

🌳Yield Farming: This is the process of earning returns by providing liquidity to DeFi protocols. Users are rewarded with tokens for providing liquidity.

Benefits of DeFi


💥Decentralization: Eliminates the need for intermediaries, reducing the risk of third-party intervention.

💥Transparency: All transactions are recorded on the blockchain, making it easy for users to track and verify.

💥Cost Savings: Reduces transaction fees compared to traditional finance.

💥Global Accessibility: Anyone with an internet connection can participate in the DeFi system.

Risks of DeFi

Smart Contract Risk: Smart contracts can contain bugs or be exploited, leading to asset loss.

Market Risk: The value of assets in DeFi can be highly volatile, posing a risk to investors.

Liquidity Risk: Some DeFi projects may face liquidity issues, making it difficult to withdraw assets.

Notable DeFi projects

Uniswap

Uniswap is one of the most popular decentralized exchanges (DEX) in the DeFi space. It operates on the Ethereum blockchain and allows users to swap ERC-20 tokens without needing an intermediary. The key feature of Uniswap is its use of an automated market maker (AMM) model, which eliminates the need for order books and instead uses liquidity pools.


  • How It Works: Users provide liquidity to the pools by depositing an equivalent value of two tokens. In return, they receive liquidity provider (LP) tokens, which represent their share of the pool. These LP tokens can be redeemed for the original tokens plus a portion of the trading fees generated by the pool.
  • Features:
    • Simple User Interface: Uniswap’s interface is user-friendly, making it accessible even for beginners.
    • Permissionless: Anyone can list a new token on Uniswap, fostering a wide range of available tokens.
    • Governance: Uniswap is governed by its community through the UNI token, which allows holders to vote on protocol upgrades and changes.

MakerDAO

MakerDAO is the project behind the stablecoin DAI, which is pegged to the US dollar and backed by a variety of cryptocurrencies. MakerDAO operates on the Ethereum blockchain and is governed by the MKR token holders.


  • How It Works: Users can lock their Ethereum and other ERC-20 tokens as collateral in MakerDAO’s smart contracts to generate DAI. The collateral must exceed the value of the DAI to ensure stability and avoid liquidation.
  • Features:
    • Stability: DAI is designed to maintain a 1:1 peg with the US dollar, offering a stable medium of exchange in the volatile crypto market.
    • Decentralization: No single entity controls DAI; instead, MKR token holders govern the protocol.
    • Collateralized Debt Positions (CDPs): Users can create CDPs by locking up collateral and generating DAI, with clear rules for maintaining and liquidating these positions.

SushiSwap

SushiSwap is a decentralized exchange that initially forked from Uniswap but has since evolved with its unique features and governance model.


  • How It Works: Like Uniswap, SushiSwap uses an AMM model. Users provide liquidity to pools and earn trading fees. Additionally, SushiSwap offers farming opportunities where users can stake their LP tokens to earn SUSHI tokens.
  • Features:
    • SushiBar: Users can stake SUSHI tokens in the SushiBar to earn xSUSHI, which accrues a portion of the trading fees generated by the platform.
    • Onsen Program: This incentivizes liquidity providers by offering additional rewards for specific liquidity pools.
    • Governance: The SUSHI token gives holders the power to propose and vote on changes to the protocol.

Advice for New Investors

➡️Thorough Research: Before investing in any DeFi project, research the project, its development team, and technical aspects carefully.

➡️Diversify Investments: Avoid putting all your money into a single project. Diversify your investments to minimize risk.

➡️Monitor the Market: Stay updated with the latest news and trends in the DeFi industry to make informed investment decisions.

Conclusion

DeFi offers numerous new opportunities for investors but also comes with several risks. Understanding DeFi and mastering the basics is crucial for effective and safe investing. With the continuous development of blockchain technology, DeFi promises to remain a field full of potential in the future.
