Decentralised Finance (DeFi) represents a new chapter in the evolution of money management, leveraging blockchain technology to rebuild traditional financial systems in an open, transparent, and permissionless way. By removing intermediaries like banks or brokers, DeFi allows users to lend, borrow, trade, and earn interest directly through peer-to-peer interactions. Built on blockchain’s core strengths—immutability, transparency, and decentralisation—it offers a trustless framework where transactions are executed through smart contracts instead of institutions. Beyond efficiency, DeFi promotes financial inclusion, lowers operational costs, and grants individuals greater control over their assets, all while maintaining privacy and accessibility on a global scale.
How can DeFi Address the Limitations of the Current Financial System?
DeFi operates on peer-to-peer financial networks, combining blockchain technology with secure protocols and modern connectivity to eliminate the need for intermediaries like banks or payment processors. In traditional systems, such entities are necessary to facilitate transactions and often charge significant fees for doing so. DeFi disrupts this model by using smart contracts to automate processes such as lending, borrowing, and trading directly between users. This decentralized structure not only enhances transparency and efficiency but also reduces transaction costs, making financial participation more accessible and cost-effective for individuals worldwide.
Benefits of Decentralised Finance
DeFi provides the following benefits:
- Accessibility: With just an internet connection, users can access DeFi platforms without geographical limitations.
- Affordable and High-Interest Transactions: DeFi facilitates direct negotiation of interest rates between parties, allowing for low-cost crypto or fiat money lending via DeFi networks, with attractive interest rates.
- Security and Transparency: DeFi platforms leverage blockchain technology, offering smart contract transparency and immutable records of transactions. This ensures security and accountability without revealing user identities.
- Autonomy: DeFi networks operate independently of centralised financial institutions, reducing administration costs and enhancing financial service efficiency.

Use Cases of DeFi
Users typically interact with DeFi through decentralised applications (dApps), many of which are currently operational on the Ethereum blockchain. Here are some common ways individuals engage with DeFi today:
- Lending: Earn interest and rewards continuously by lending out your crypto.
- Borrowing: Access instant loans without extensive paperwork, including short-term “flash loans” not typically offered by traditional financial institutions.
- Trading: Engage in peer-to-peer trading of specific crypto assets, similar to buying and selling stocks without requiring a brokerage.
- Saving: Deposit crypto into alternative savings accounts to earn higher interest rates than those offered by banks.
- Derivatives Trading: Speculate on asset prices with long or short positions, akin to stock options or futures contracts in the traditional financial markets.
Decentralised Lending and Borrowing Platforms
Following are some examples of Lending and Borrowing DeFi platforms:
Aave (AAVE)
Aave, operating on the Ethereum blockchain, is a DeFi protocol providing diverse decentralized lending services. Users can engage in lending, borrowing, and earning interest on various digital assets or crypto assets. Similar to traditional financial lending, Aave requires borrowers to provide collateral or have collateral delegated to access crypto loans.
At the time of writing, AAVE was trading at around $212.06, having a market capitalization of around $3.23 billion.

Compound (COMP)
Compound Finance, like Aave, enables users to quickly lend or borrow crypto assets within minutes. The platform’s smart contracts, which form the algorithmic money market protocol, streamline the process for users, automatically determining collateral requirements and interest rates without the need for direct negotiation between borrowers and lenders.
As of now, COMP is trading near $33.70, with a total market capitalization of approximately $324.96 million.

Stablecoins and Their Usage in DeFi Applications
Stablecoins are crypto assets pegged to match a financial asset or currency like the US Dollar or gold. True to their name, the values of these tokens are relatively stable. These are very popular among crypto traders who want a non-volatile store of value:
Dai (DAI)
Dai, a widely recognised USD-pegged stablecoin, is overseen by Maker and its decentralised governance community, MakerDAO. Dai maintains its value in line with the US dollar through collateral deposits from users, which in turn generates Dai’s supply. For instance, when a user deposits Ether as collateral into a Maker Vault to generate Dai, they can utilise it in other DeFi protocols or decentralised applications.
At the time of writing, DAI was valued at approximately $1, with a total market capitalization of about $5.36 billion.

Tether (USDT)
USDT, one of the oldest and most widely used stablecoins, is issued by Tether Limited. It maintains its 1:1 peg to the US dollar by holding a mix of cash reserves, short-term deposits, and other liquid assets. For example, when an exchange or user deposits USD with Tether, an equivalent amount of USDT is issued, allowing them to trade or transfer funds across exchanges instantly without relying on traditional banking channels.
At the time of writing, USDT was trading near $1, with a market capitalization of roughly $184.02 billion.
USD Coin (USDC)
USDC, managed by Circle and governed by the Centre Consortium (which includes Coinbase), is a fully collateralized stablecoin backed by cash and short-term U.S. Treasuries. Its transparency and regular audits have made it a preferred choice among institutional and retail users. For instance, when a user transfers $1 to Circle, they receive 1 USDC in return, which can then be used across DeFi platforms, exchanges, or payment applications with full on-chain traceability.
At the time of writing, USDC was valued at around $1, with an estimated market capitalization of $76.05 billion.
Future of DeFi
The possibilities ahead are vast and transformative. The crypto market is on track for remarkable expansion, with estimates suggesting its total value could triple by 2030. As regulatory clarity improves and global governments begin to recognize the potential of digital assets, the stage is set for greater adoption across industries. Continuous technological innovation—through advancements in blockchain scalability, interoperability, and DeFi infrastructure—will further strengthen this evolution. Together, these forces are paving the way for crypto to transition from a niche investment class to a fully integrated pillar of the global financial system.

Conclusion
Decentralised Finance (DeFi) revolutionises traditional financial systems by leveraging blockchain technology to offer accessibility, affordability, security, autonomy, and innovative financial services. Through DeFi platforms, users can engage in lending, borrowing, and trading with ease, while stablecoins provide stability and utility within the DeFi ecosystem.
The future of DeFi looks promising and the community is actively building more innovative products. New support from the community as well as governments and regulators are expected. This can potentially transform the way we interact with financial services.
