Decentralized finance (DeFi) is a cryptocurrency industrial sector that focuses on offering decentralized financial services. It is made up of a variety of financial services provided by developers that anybody may use. These services differ from centralized alternatives in that they are managed by groups of people through decentralized organizations and provide consumers with more control over their finances.

Every week, new decentralized and non-custodial financial services are launched in the DeFi industry, which is a hub of innovation. These services are available to everyone, wherever in the globe.

According to World Bank estimates from 2017, over 1.7 billion adults worldwide were expected to be unbanked – that is, without a financial institution account. Because there are no entrance criteria for financial services on DeFi protocols, anybody can use them. In essence, the only barrier to entry is knowledge.

The DeFi ecosystem is built on top of public distribution networks and employs self-executing agreements put into lines of code known as smart contracts to democratize access to financial services.

DeFi extends beyond the generation of new digital money or value, despite the fact that it is commonly addressed in relation to cryptocurrencies. The purpose of DeFi’s smart contracts is to replace traditional financial systems.

Because there are no middlemen to approve transactions for DeFi applications, there are no banks or other organizations to manage your money. DeFi protocols are transparent because the code is accessible to everyone for inspection. There are open networks as well that cross international borders. Users may choose from a wide variety of applications, the majority of which are based on the Ethereum blockchain.


What makes up decentralized finance (DeFi)?

DeFi boomed in 2020, bringing an influx of projects into the crypto sphere and popularizing a new financial movement. Since Bitcoin essentially holds many DeFi characteristics, no firm start date exists for the inception of the DeFi sector, other than Bitcoin’s launch in 2009.

Following 2017, however, numerous ecosystems gained popularity, such as Compound Finance and MakerDAO, popularizing extra financial possibilities for crypto and DeFi. In 2020, the DeFi niche gained off as new platforms emerged, as people began to use DeFi solutions for techniques such as yield farming.


How to use DeFi protocols?

The majority of DeFi protocols are developed on top of networks such as Ethereum or Binance Smart Chain, and the number of competing blockchain networks that allow smart contracts is expanding. It is critical to select a network before using DeFi services.

Most significant protocols now support many blockchains, with the main differences being ease of use and transaction costs. Networks such as Ethereum, Binance Smart Chain, and Polygon are all available via wallet extensions like a MetaMask, with only a few settings changing to switch networks.

Users may use these wallet extensions to access their funds straight from their browsers. They are installed in the same way as any other extension and frequently require users to either import an existing wallet — through a seed phrase or a private key — or create a new one. They are also password-protected for further protection. Some web browsers include built-in wallets.

Furthermore, these wallets frequently include mobile applications that may be used to access DeFi initiatives. These apps are wallets with built-in browsers that can interact with DeFi apps. Users can sync their wallets by creating them on one device and importing them onto another using the seed phrase or private key.

These mobile applications frequently include the open-source WalletConnect protocol to make things easier for consumers. By scanning a QR code with their phones, customers may link their wallets to DeFi programs on desktop machines.

Before we begin, it is important to note that this is a very experimental space with a variety of risks. Exit scams, fraudulent ventures, rug pulls, and other types of fraud are frequent, so always conduct your own research before investing.

To prevent falling for these tactics, here’s how to take security a step further: It is advisable to find out whether or not the projects have been audited. Finding out this information may require some effort, but typically a straightforward search for the project’s name with “audits” can disclose whether or not it has been audited.

Audits assist to identify possible vulnerabilities while discouraging undesirable actors. Projects that are less than exceptional are unlikely to waste time and money by being audited by renowned firms.
