What is decentralised finance (DeFi)?
In an increasingly digital and connected world, DeFi – or decentralised finance – represents a groundbreaking movement aiming to transform traditional finance. At its core, it shifts technologies and processes like transactions into the hands of individuals to reduce dependency on central institutions.
In this guide, we’ll explain exactly what DeFi means, how it works and how you can get started in the world of decentralised finance. We’ll also explore the risks and challenges in depth, and how DeFi could reshape the traditional financial system.
Decentralised finance (DeFi) replicates traditional financial services but with a focus on transparency.
DeFi promotes financial inclusion and equality of opportunity by offering access to a global financial market without geographic restrictions or the need for a traditional bank account.
Applications aren’t managed or controlled by central authorities but are built on blockchain technology, meaning transactions occur directly between users.
Smart contracts are a core element of the DeFi sector. They encode agreements between "buyer" and "seller" directly into code, removing the need for a middleman.
DeFi, short for decentralised finance, refers to a financial application ecosystem based on blockchain technology, designed to bypass and improve traditional finance. It enables users to carry out transactions and services such as loans, exchanges and investments directly, without intermediaries. The core principles of DeFi are decentralisation, openness, accessibility and transparency. Smart contracts allow for automated agreements without central authority.
Unlike the traditional financial system, which relies on centralised institutions like banks and governments, DeFi distributes power across a network of users. This supports greater financial inclusion, enabling virtually anyone with internet access to join global financial markets. By using blockchain, DeFi offers enhanced security and transparency, as all transactions are publicly and immutably recorded.
Building blocks and infrastructure of the DeFi ecosystem
Decentralised finance, or DeFi, is made up of various key components. Together, they form an ecosystem that brings traditional financial services onto the blockchain. These components allow users to interact without central institutions, providing greater transparency, security and accessibility.
Decentralised applications (DApps)
Decentralised applications, or DApps, are the core of the DeFi ecosystem. They run on a crypto blockchain and offer users a wide range of financial services without the involvement of central authorities. By using smart contracts and DApps, automated processes such as lending, trading and investing become possible.
DApps aren’t limited to the Ethereum (ETH) protocol but are also used across other blockchain platforms, making a broad range of financial services globally accessible.
Smart contracts
Smart contracts are the central element of DeFi and enable the creation of automated agreements. These self-executing contracts are stored on the blockchain and carry out pre-defined actions once specific conditions are met, without requiring a central authority.
Their applications in DeFi are wide-ranging, from processing transactions and creating tokens to automating interest payments and conducting governance votes. Smart contracts are therefore essential for building efficient and transparent decentralised financial systems.
DeFi tokens and stablecoins
DeFi tokens and stablecoins are digital assets that play a key role in decentralised finance. DeFi tokens often serve as governance tokens within a specific DeFi project, giving holders voting rights or a share of the revenue.
Stablecoins bridge the gap to traditional finance by ensuring price stability. They're pegged to stable assets such as the US dollar, reducing the volatility common in cryptocurrencies. Both types of digital currency enable a wide range of financial transactions in DeFi, from securing loans to speculative trading.
Decentralised exchanges (DEXs)
Decentralised exchanges (DEXs) enable users to trade cryptocurrencies directly with each other, without needing a central custodian. Unlike traditional exchanges, DEXs do not hold users’ funds but use smart contracts to facilitate and secure trades.
This independence from central authorities reduces the risk of theft, censorship and downtime. DEXs are a key element of DeFi as they lay the foundation for open, accessible and secure trading of digital assets.
Decentralised lending and saving platforms
Decentralised lending and saving platforms are innovative financial tools that let users borrow, lend and earn interest on their crypto assets. These platforms use smart contracts to manage collateral and define loan terms, creating a secure and transparent environment for financial transactions.
Users can make their assets work for them by lending them out or using them as collateral. This transforms the traditional banking model and paves the way for a more inclusive financial world.
Decentralised wallets
Decentralised accounts, also known as wallets, are the gateway to participating in the DeFi ecosystem. While traditional bank accounts are controlled by central institutions, wallets give users full control over their digital assets. They operate using a combination of private and public keys – private keys authorise transactions, while public keys serve as receiving addresses.
Web3 wallets are a specialised form of decentralised wallet that also enables access to DApps. They offer high levels of security and autonomy, giving users full control over their funds while providing easy access to the global financial system without traditional banking infrastructure. Decentralised wallets are therefore the backbone of an inclusive and autonomous financial world.

Get startedYour entry into the world of decentralised finance (DeFi)
DeFi opens up an exciting world full of possibilities, but it can also be overwhelming for beginners. From setting up your decentralised account – your wallet – to taking your first steps on DeFi platforms, there’s a lot to consider.
Setting up decentralised wallets
Your first step into the DeFi world is opening a decentralised account in the form of a crypto wallet. This acts like a digital purse in the blockchain world, allowing you to send, receive and store cryptocurrencies.
When choosing a wallet, make sure it’s compatible with the DeFi services you’re interested in. Security is key: note down your private key somewhere safe, and consider using a hardware wallet for larger amounts to protect your digital assets.
For more on how wallets work and how to set one up, see our guide "What is a wallet and where do I get one?"
Buying DeFi coins and tokens
Once your wallet is set up, you’re ready to buy cryptocurrencies. Ethereum (ETH) is a good place to start, as most DeFi projects are built on the Ethereum blockchain. Buying and selling coins and tokens – also known as trading – can be done via brokers or exchanges, each with their pros and cons.
Brokers like Bitpanda are usually ideal for beginners, as they act as intermediaries between investors and the market, offering services that make trading simpler and more user-friendly. Exchanges, on the other hand, enable direct trading between buyers and sellers. They tend to be more complex but offer advanced tools for experienced crypto traders.

Challenges and disadvantages of DeFi
While DeFi has many advantages, there are also risks and drawbacks:
Smart contract risks
Fraud in the DeFi ecosystem
Liquidity risks
High volatility
Regulatory uncertainty
Technical vulnerabilities
Smart contract risks
Smart contracts are the backbone of DeFi apps but aren’t risk-free. Bugs or security gaps can lead to major losses. To reduce risk, invest in projects whose smart contracts are regularly audited by third-party security firms. While not foolproof, audits add a layer of trust.
Fraud and scams in DeFi
DeFi isn't immune to scams, including “rug pulls” where developers disappear with users' funds. Conduct thorough due diligence before investing, and look for trustworthy community feedback to identify reliable platforms.
Liquidity risks
Liquidity issues arise when there aren’t enough funds to meet trading demands or withdrawals. Reduce this risk by investing in high-liquidity pools.
Volatility risks
Crypto prices can fluctuate significantly, directly affecting your DeFi investments. Long-term strategies and tools like stop-loss orders can help manage this risk.
Regulatory risks
DeFi regulations vary worldwide. This can create uncertainty and risk for both projects and investors. Keep up with laws and developments in your country and how they might affect your activities.
Technical risks
Advanced technologies come with technical weak spots. Wallet and platform security is crucial. Use hardware wallets and review security practices regularly to reduce risk.
