The size of the global Blockchain technology market is set to reach $1.4 trillion by 2030 while growing at 87% annually from 2023 to 2030. 

Within this market, Solidity has emerged as a top programming language that is specifically designed to create smart contracts. 

This article provides insights and strategies to hire Solidity Developers and explores how such talents can be hired from Poland and Ukraine. 

What Is Solidity?

Solidity is an open-source programming language that has been designed for developing smart contracts on the Ethereum Blockchain. It enables Developers to define the rules and logic when creating decentralized applications (DApps).

What Does a Solidity Developer Do? Roles & Responsibilities

Solidity Developers play a major role in shaping the success of a Blockchain project. Some of the key responsibilities of Solidity Developers include: 

  • Writing clean code for creating decentralized applications
  • Writing tamper-proof smart contracts
  • Integrating Ethereum-based modules
  • Testing the security of the Ethereum-based smart contracts
  • Writing code libraries and running automated tests
  • Seamlessly integrating smart contracts with Blockchain networks
  • Optimizing the smart contracts to minimize gas usage and increase efficiency
  • Working with cross-functional teams to ensure project success
Being a Solidity developer is not just about understanding code, it's about envisioning the limitless possibilities of blockchain technology.
Behind every successful blockchain project is a Solidity developer, translating complex ideas into smart contract reality.

What Can You Do with Solidity?

Before looking at Solidity Developers for hire, it is important to know what you can build with Solidity. Some key use cases of Solidity include: 

  • Voting: It is possible to create voting systems that are automatic, transparent, and immutable with Solidity. 
  • Safe Remote Purchase: Remotely purchasing goods and services has multiple parties where trust needs to be established. Through the creation of a smart contract with Solidity, the amount for the good is locked until both parties agree to its completion. 
  • Creating and Verifying Signatures: It is possible to authorize transactions by using verified signatures which have smart contracts on Ethereum. 
  • Verifying Payments: Through Solidity, verification mechanisms can be created to ensure that payments are redeemed only after they have been proven as valid. 

Blockchains that Use Solidity

There are many Blockchains that use Solidity for their businesses. These include Tron, Polygon, Ethereum, Counterparty, Binance Smart Chain, and Avalanche C-Chain. 

For instance, the distributed ledger technology company called Hedera Hashgraph has been using Solidity to enable its users to create and execute smart contracts. Their users can create Auctions and DeFi applications with low fees using Solidity. 

Key Skills to Look Out for When Hiring Solidity Developers

Skills are the most important factor before hiring a tech talent. Some important Solidity Developer skills to assess include

Recruiters need to be aware of the following technical skills that should be carefully evaluated among the Software Developers: 

  • Proficiency in Solidity Programming: The most important skill to measure is proficiency in Solidity. Assess their previous experience building smart contracts using Solidity. 
  • Understanding of Ethereum Blockchain and EVM: As Solidity is primarily focused on smart contracts in Ethereum, understanding about this Blockchain and the Ethereum Virtual Machine (EVM) is vital. Ask about Mining, Gas fees, and smart contract deployment in Ethereum. 
  • Experience with Front-end and Back-end Development: Assess their experience with front-end languages such as JavaScript and HTML. For the back-end, ask about familiarity with Node.js while for the database, consider asking about MongoDB, and MySQL. 
  • Knowledge of Blockchain Testing and Debugging Tools: For running smart contracts correctly without any problems, ask if they can use Remix IDE, Truffle, Ganache, and OpenZeppelin. 
  • Familiarity with Smart Contract Standards and Regulations: There are strict regulations that need to be followed for smart contract development. Quiz them on their understanding of ERC-20, ERC-72, and ERC-1155. 

2. Strong Communication and Collaboration Skills

Working within a cross-functional team environment requires active listening, empathy, and ability to receive feedback. Furthermore, candidates need to have both verbal and written communication skills. 

3. Problem-solving and Critical Thinking Abilities

Finding issues and recommending feasible solutions requires the ability to analyze complex problems in a fast-paced environment. Consider designing the interview to include complex problem-solving to measure their competency. 

4. Time Management and Organizational Skills

Evaluate their experience in utilizing tools like Jira to prioritize their tasks and what techniques they use to stay productive. Furthermore, ask about their previous experience in handling tight deadlines to deliver high-quality work. 

5. Adaptability and Continuous Learning

To adapt to the constantly evolving smart contract landscape, candidates need to stay updated on new technologies and tools that enhance their work. Additionally, they should be flexible in working as per new changes in regulations.

Common Mistakes to Avoid When Hiring Solidity Developers

Since many recruiters may not be familiar with hiring Solidity Developers, mistakes are possible. Therefore, try avoiding the following errors in the hiring process:

  • Neglecting Technical Proficiency: Prioritizing expertise in Solidity is necessary as working with this programming language along with complementary tools will be their main task. 
  • Overlooking Blockchain Knowledge: Lack of Blockchain knowledge will make it difficult for the Developers to successfully deliver results. Ask the candidates about their understanding of key Blockchain concepts such as consensus mechanisms and smart contracts. 
  • Ignoring Regulatory Awareness: As the Blockchain ecosystem’s regulatory landscape is constantly evolving, it is imperative to measure their awareness about regulations so they can design compliant smart contracts. 
  • Neglecting Soft Skills: Failing to communicate their ideas and work together with other members may result in a candidate who is hard to work with. 
  • Skipping Quality Assurance Evaluation: Hiring Solidity Developers who haven’t done rigorous testing of their smart contracts may lead to applications that have high-security risks. 

How to Hire a Solidity Developer: Choosing the Perfect Candidate

Creating a streamlined hiring process will help to hire a Solidity Developer more effectively. Some strategies to achieve this include
