Decentralized finance (DeFi) has quickly taken over the world, especially when it comes to crypto. DeFi platforms are becoming synonymous with banks for people who want to borrow or lend funds, earn interest on their traditional savings-like accounts and insure against risks without institutional control.

According to International Data Corporation (IDC), the worldwide spending on blockchain solutions like DeFi apps will be nearly $19 billion by 2024. Previously, Bitcoin was the only hype-generating cryptocurrency, but many altcoins and meme coins have started becoming the talk of the town these days.

Markets and Markets forecast the global blockchain technology industry to grow to $70 billion by 2026. Thus, it makes sense why companies might want to hire DeFi developers to benefit from the window of opportunity to take some game-changing initiatives.

In this guide, you'll learn how to hire DeFi engineers and which skills decentralized finance developers must have.

What is DeFi?

DeFi or decentralized finance is an infrastructure aimed at increasing the number of market participants in the financial sector by eliminating intermediaries and centralized systems. The most appealing part of the DeFi space is the lack of custody or centralization. Conventionally, centralized exchanges and banks impose several regulations for people who use their services. But DeFi is devoid of these regulations, making it a lucrative option for developers who want to explore opportunities without being limited by a central body or intermediary.

Due to this, DeFi has the following benefits:

  • You don't have to pay the bank fees, such as annual ATM charges or expenses for further services.
  • Your money is safe in a digital wallet rather than a bank account.
  • You don't have to go through hoops to open an account since your credit history or earnings do not matter in DeFi. You can open an account on DeFi apps as long as you have an internet connection.
  • Funds transfer takes a few seconds or minutes.
  • Unlike banks, the DeFi space is never closed for holidays or weekends.
  • You can open anonymous accounts for keeping your digital currency or trading.
  • You get access to financial services, such as loans, without going through a long and complicated process as you would with a conventional financial institution, like a bank.

Just like cryptocurrency, DeFi uses blockchain technology. As IBM explains, a blockchain is a "shared, immutable ledger" that tracks and records transactions of assets. Immutable means that the blockchain cannot be changed. All transactions made on the public ledger will remain on it permanently.

In summary, decentralized applications are services built on a blockchain. dApps offers the same financial services as your bank (savings accounts, lending, borrowing, etc.) but with the benefits mentioned above.

Top Blockchains Used for DeFi and the Developer Skills Needed

As mentioned, DeFi apps or projects are built on blockchains, decentralized public ledgers facilitating the recording and processing of transactions in a network. But a blockchain is only as good as its business network. The most successful DeFi projects are built on top of some of the largest blockchains in the world.

When you hire decentralized finance developers, you need to be sure they can work with different blockchains or at least the one you plan to use for your project. Ethereum is currently leading the DeFi sector with a significant market share, but it's not the only blockchain developers can use for projects.

Let's explore Ethereum and two other popular blockchains DeFi developers can utilize.

Ethereum (ETH)

Ethereum is a decentralized platform that runs smart contracts. Developers can use it to host DeFi apps like Augur, MakerDAO, and 0x.

Ethereum is by far the largest blockchain in the DeFi sector due to its fast transaction execution speed and the following reasons:

  • Seamless Interconnectivity: All DeFi projects made on Ethereum have the same basis and underlying mechanism. Thus, they integrate seamlessly.
  • Built-In Crypto: Ethereum's cryptocurrency, ETH, is built into the network. Meanwhile, the blockchain keeps track of all transactions.
  • Financial Freedom: When you create a DeFi product on Ethereum, you have full financial freedom as there's no central governing body involved.


Ethereum can help you create apps for many financial products that you normally get from centralized institutions, such as banks. For instance, you can use Ethereum to create a DeFi app for flash lending. Flash loans are decentralized loans, which implies borrowing funds doesn't involve giving personal details or providing collateral. Although they're not accessible for people who're not in the DeFi space, there's a high likelihood these loans will become a norm in the future. The main attraction of flash loans is that users can lend money instantly without going through a central authority such as banks.

Apart from this, Ethereum's DeFi capabilities also let you send money to anyone anywhere around the world, access stable currencies, trade tokens, grow your investment portfolio, buy insurance, and create apps. But when you hire DeFi engineers to build all these projects, you must ensure they have the right programming skills.

Programming Skills Required

Firstly, the DeFi developers need to be familiar with programming languages like Python, Ruby, and JavaScript. Apart from that, they must have a grasp of the following:

  • ERC-20: These tokens are built on top of Ethereum, and they work as an intermediary for all DeFi transactions.
  • Solidity: A programming language named Solidity is designed for developing smart contracts on the Ethereum blockchain.
  • CK2: This token framework allows you to create new tokens on top of Ethereum.

Solana (SOL)

Solana is a blockchain built for high throughput and scalability. It has a processing speed of  65,000 transactions per second, which is similar to other popular blockchains. Although it's not as popular as Ethereum, Solana is widely used due to its capabilities to process large amounts of transactions per second.


The main attraction of Solana is its speed, but there are some other reasons why it's so popular among DeFi developers:

  • Low Transaction Cost: The transactions on Solana cost much less than on Ethereum. Lower expenses paired with high throughput make Solana an attractive option for DeFi developers.
  • Scalability: Due to the boom in the NFT and DeFi space, there's a growing need for platforms to be scalable. Solana had managed to do this by using Proof of History, an innovative technology that can reference previous hashes and tell users when exactly a transaction occurred.

Programming Skills Required

Before you hire DeFi developers to build on Solana, make sure they are proficient in the following programming languages:

  • Rust: This is a system programming language used to write on-chain programs on Solana. Since it lies in Solana's core, DeFi developers need to learn Rust and understand its involvement in cross-program invocations.
  • C++: The smart contract language used by Solana is C++. Developers should also be familiar with C.

The developers should also have an excellent grasp of Solana's source code since it defines how the blockchain's technology works. Fortunately, the source code is available for free on Solana Lab Github.

Avalanche (AVAX)

Avalanche is a relatively newer blockchain, but it has become popular in the DeFi field. The platform runs smart contracts and aims to deliver scalability with high-level security and low costs. Another attractive feature of Avalanche is its focus on eco-friendliness as the DeFi gets a lot of critiques on its neglect of sustainability.


Initially, Avalanche was created to solve several problems in the DeFi world, such as:

  • Congestion. Something that's concerningly lacking in older blockchains is scalability. Avalanche was specifically designed with a keen focus on scalability. The platform's Snowman Consensus Protocol and subnet feature enable more seamless transactions than other blockchains.
  • Low Fees. Like Solana, Avalanche has lower fees than Ethereum. Due to this, DeFi developers can work with Avalanche without worrying about the financial aspects of their projects.
  • Transaction Speed. With sub-second transaction speed, Avalanche can process nearly 6500 transactions per second.
  • Sustainability. Avalanche uses an energy-efficient consensus algorithm instead of the proof-of-work that most other platforms use.

Programming Skills Required

The DeFi developers you hire to build projects on Avalanche must understand the Consensus Protocol, which is the main factor in understanding and validating transactions. They should also know how the Hashgraph works and what factors affect its outcomes. Knowledge of the Snowman Consensus Protocol (powered by the blockchain's consensus protocol) is also imperative.

Experience writing ETH smart contracts is also valuable since AVAX natively supports Solidity.

Depending on your DeFi needs, the developers must be familiar with one or all of these chains:

  • X-Chain: This is a decentralized platform where developers can create and trade digital assets. With the X-Chain API, developers can exchange or build assets on the Avalanche Virtual Machine.
  • P-Chain: The Platform Chain or P-Chain can help create blockchains and subnets. Developers also use this to add validators to the subnets they have created.
  • C-Chain: The Contract Chain lets developers make smart contracts.
