Decentralized Finance (DeFi) is reshaping global finance by replacing traditional intermediaries with open, permissionless protocols on blockchains like Ethereum. The sector’s total value locked (TVL) reached over $118 billion in December 2025, and the market is projected to grow to 616 billion by 2033, depending on the forecast, driven by institutional adoption and demand for transparent, global financial services.
This DeFi business model is not just a niche crypto trend; it’s a structural shift in how lending, trading, and asset management are delivered. In this post, we’ll break down how DeFi protocols actually work, how they make money, who their customers are, and what benefits and risks they bring.
The defi business model allows for unprecedented flexibility, enabling users to tailor their financial experiences according to their unique needs.
What DeFi Solves and How It’s Used
Removing Intermediaries and Gatekeepers
This shift towards a defi business model not only enhances user experience but also democratizes access to financial services.
Traditional finance relies on banks, brokers, and clearinghouses to facilitate lending, trading, and payments, which introduces counterparty risk, high fees, and geographic exclusion. DeFi protocols replace these intermediaries with smart contracts that execute financial logic automatically on public blockchains. This removes the need for a central party to hold custody of funds or approve transactions, reducing both operational costs and systemic risk. For example, instead of a bank deciding whether to grant a loan, a DeFi lending protocol uses over-collateralization and automated liquidation to manage credit risk without a credit check.

By utilizing a defi business model, users can engage in financial transactions without the constraints of traditional banking systems.
Enabling Permissionless, Global Access
DeFi protocols are open to anyone with an internet connection and a crypto wallet, making financial services accessible to the unbanked and underbanked. According to the World Bank, around 1.7 billion adults remain unbanked, but many own mobile phones that can access DeFi. This permissionless access is particularly valuable in regions with weak banking infrastructure, where DeFi can provide savings, lending, and trading services that were previously unavailable or prohibitively expensive.
With the defi business model, the potential for innovation is vast, as new services and protocols continue to emerge.
Understanding the defi business model is essential for anyone looking to navigate the evolving landscape of finance.
Core Use Cases in Practice
The success of the defi business model hinges on the network effect, where more participants lead to greater value for all.
DeFi is used for a wide range of financial activities, including decentralized exchanges (DEXs) for trading tokens, lending and borrowing protocols for credit, stablecoins for price-stable value transfer, and yield farming for earning returns on idle assets.
Businesses use DeFi to reduce cross-border payment costs, automate treasury workflows, and access global liquidity pools for working capital. For example, a company can use a DEX to swap currencies in minutes instead of waiting days for a bank wire, or use a lending protocol to borrow against its crypto holdings without selling them, improving capital efficiency.
The DeFi Business Model in Detail
How DeFi Protocols Generate Revenue
As users become more acquainted with the defi business model, we can expect to see increased adoption rates.
DeFi protocols monetize primarily through fees charged for their services, which are collected on-chain and can be shared with the protocol’s treasury, liquidity providers, and token holders. The exact revenue model depends on the type of protocol:
- Decentralized exchanges (DEXs) like Uniswap and Curve generate revenue from trading fees. For example, Uniswap charges a 0.3% fee on each swap, which is distributed to liquidity providers. Some protocols, like Curve, also direct token emissions (CRV rewards) to liquidity providers to incentivize deeper liquidity, effectively using token inflation as a cost of doing business.
- Lending protocols like Maker and Aave earn revenue from the interest spread between borrowers and lenders. Maker charges a “stability fee” on borrowed DAI, while Aave takes a cut of the interest paid by borrowers. These fees are collected by the protocol and can be used to fund development, governance, or distributed to token holders.
- Derivative exchanges like dYdX generate revenue from trading fees on perpetual futures and other derivatives, with a portion of those fees going to the protocol’s treasury and the rest to liquidity providers or stakers.
The Role of Governance Tokens and Incentives
Most DeFi protocols issue governance tokens (e.g., UNI, AAVE, CRV) that give holders voting rights on protocol upgrades, fee changes, and other parameters. These tokens are often used to bootstrap liquidity and user adoption through “yield farming” or liquidity mining, where users earn tokens by providing liquidity or using the protocol. Over time, successful protocols aim to transition from relying heavily on token emissions to being profitable from fee revenue alone, so that the protocol can sustainably grow without constant inflation.
Treasury and DAO Governance
DeFi protocols are typically governed by decentralized autonomous organizations (DAOs) that manage a treasury of assets and tokens. The treasury is funded by protocol fees, token sales, and sometimes venture capital, and is used to pay for development, security audits, marketing, and ecosystem grants. Governance proposals voted on by token holders determine how the treasury is allocated, creating a decentralized, community-driven business model that contrasts sharply with traditional corporate structures.
The defi business model empowers users with tools that were previously reserved for financial institutions.

Types of DeFi Customers
Retail Users and Crypto Enthusiasts
Ultimately, the defi business model provides a framework for a more equitable financial future.
The largest group of DeFi users are retail investors and crypto enthusiasts who use DeFi to earn yield, trade tokens, and gain exposure to new assets. These users are attracted by the potential for higher returns compared to traditional savings accounts, as well as the ability to participate in governance and shape the protocols they use. They typically interact with DeFi through self-custody wallets like MetaMask and are comfortable with some technical complexity.
Institutional and Professional Participants
As challenges are addressed, the defi business model will continue to evolve and adapt to market needs.
Institutional investors, hedge funds, and professional traders are increasingly using DeFi for liquidity provision, arbitrage, and structured products. These users value the transparency, auditability, and composability of DeFi protocols, which allow them to build sophisticated strategies across multiple platforms. Institutional-grade DeFi solutions are being developed to meet compliance requirements, including KYC/AML checks and risk management tools, making DeFi more attractive to traditional financial institutions.
Small and Medium Enterprises (SMEs)
SMEs benefit from DeFi by accessing new funding avenues and improving working capital efficiency. Through DeFi lending, SMEs can borrow against crypto assets or tokenized real-world assets, bypassing traditional credit checks and lengthy approval processes. DeFi also enables SMEs to reduce cross-border payment costs and settlement times, improving cash flow and competitiveness in global markets.
Benefits and Challenges of the DeFi Model
Key Benefits
DeFi offers several compelling advantages over traditional finance:
- It provides transparency, as all transactions and smart contract code are publicly verifiable on the blockchain.
- It enables efficiency, with near-instant settlement and lower fees compared to traditional intermediaries.
- It promotes financial inclusion, giving access to financial services for the unbanked and underbanked.
- It supports innovation, with new financial products like flash loans, yield farming, and automated market makers that were not feasible in traditional systems.
Major Challenges
Despite its promise, DeFi faces significant challenges.
- Smart contract risk remains a concern, as bugs or exploits can lead to large losses, as seen in high-profile hacks.
- Regulatory uncertainty is a major barrier, with agencies around the world still developing frameworks for DeFi, stablecoins, and governance tokens.
- User experience can be complex for non-technical users, and liquidity risk can arise in stressed market conditions, especially for less established protocols.
Addressing these challenges is critical for DeFi to achieve mainstream adoption and long-term sustainability.
