Bitaigen Research What Is DeFi
DeFi is a decentralized finance system built on blockchain smart contracts that does not rely on traditional financial institutions. Users can lend, borrow, trade and perform many other financial activities in an open, global, permission‑less environment.
DeFi is an abbreviation of the English term Decentralized Finance, commonly referred to as “decentralized finance.” Some industry participants also use “distributed finance” or “open finance” to describe the same concept. In this article we will consistently use “decentralized finance” to refer to DeFi.
DeFi realizes financial functions through smart contracts, with the most typical implementation platform being Ethereum. Smart contracts enable users to carry out a wide range of operations such as borrowing and lending, speculative bidding, token swapping, risk hedging, and earning interest.
In this article we systematically outline the core concepts and operating mechanisms of DeFi, clarify key attributes such as decentralization, open‑source code, and permission‑lessness, and place particular emphasis on the DApp platforms that underpin these functions. By using easy‑to‑understand examples and technical analysis, readers can quickly build a comprehensive view of the decentralized financial ecosystem. Subsequent sections will delve deeper into concrete project implementation pathways, making this a worthwhile read.
Characteristics of DeFi
DeFi’s rapid rise is due not only to token incentives offered by project teams but also to several intrinsic features. Most DeFi applications do not depend on centralized institutions or organizations; the rules and execution logic are fully encoded in smart contracts. Once a contract is deployed to a blockchain, it can operate automatically without human intervention (although project teams may occasionally upgrade or maintain the code).
Typical traits of DeFi applications include:
- Open‑source code: All contract code is publicly available, enhancing transparency.
- Public transactions: Transaction records are permanently stored on the blockchain and can be inspected by anyone.
- Global, borderless: Anyone with an internet connection can participate, without the need for cross‑border licenses.
- Permission‑less: No central authority approval is required; anyone can use the service.
- Flexible user experience: Supports multiple wallets and on‑chain assets, lowering the entry barrier.
- Interoperability: Different DeFi protocols can be combined to create more sophisticated financial products.
Classic DeFi Projects
MakerDAO
MakerDAO, founded in 2014, is an Ethereum‑based collateralized lending platform and is widely regarded as the pioneering project of the DeFi movement. Its core function allows users to lock tokens from the Ethereum ecosystem as collateral and borrow the USD‑pegged stablecoin DAI. To facilitate governance and incentives, MakerDAO issues two tokens:
- MKR: Used for governance voting within the system.
- DAI: A stablecoin pegged to the US dollar, employed for borrowing and other financial activities.
Uniswap
Uniswap is a decentralized exchange (DEX) on Ethereum that employs an automated market maker (AMM) model to enable instant token swaps. Unlike traditional exchanges that match orders through an order book, Uniswap automatically prices trades via liquidity pools, reducing reliance on centralized matching engines. While Bancor first introduced the AMM concept, Uniswap refined the mechanism and popularized it across the ecosystem.
Synthetix
Synthetix provides issuance and trading services for synthetic assets. Users can mint synthetic tokens, known as Synths, which track the price of underlying assets in real time through oracle feeds. Major synthetic assets include:
- sBTC: A synthetic asset pegged to Bitcoin.
- sXAU: A synthetic asset pegged to gold.
- sUSD: A synthetic asset pegged to the US dollar.
The platform utilizes two token types:
- SNX: Grants both governance voting rights and the ability to mint synthetic assets.
- Synth: The individual token representing each synthetic asset.
Nexus Mutual
Nexus Mutual is an Ethereum‑based decentralized insurance platform where users can purchase coverage for DeFi projects. If a covered project suffers a loss due to a hack or other unexpected event, community members holding the NXM token vote on the validity of a claim, creating a mutual risk‑sharing insurance mechanism.
Industry Outlook
Within the broader cryptocurrency space, DeFi remains in a phase of rapid exploration. Although several flagship projects have already emerged, many niche segments are still under‑developed. Future innovation directions are expected to include cross‑chain interoperability, composable financial products, and more efficient governance models.

*Note for U.S. readers:* Access to global DeFi services may require the use of Binance.US rather than the international Binance platform. For fiat‑on‑ramp and off‑ramp, USD transfers via SEPA/SWIFT are commonly supported in the global market.
