By hiring a blockchain development team skilled in smart contracts, you will be setting your business up for future success

Solidity

It is the most commonly used language for creating smart contracts, especially with the Ethereum ecosystem. Ethereum is still one of the most robust and established platforms for building decentralized applications.

Rust

In contrast, Rust is better known in the blockchain ecosystem for speed and security. Projects like Solana are typical Rust-based blockchain platforms that need performance or security-focused solutions. Developers who are proficient in Rust will create quick, safe, and highly secure applications for the projects you need to deliver at scale.

Web3.

Web3. JS is a JavaScript library that helps the end user to easily use the huge, powerful abilities of the Blockchain data once a web wallet such as MetaMask or Talisman has been properly connected. By focusing on these three tools of the trade, you are hiring a team of developers who are building space-aged, reliable, and high-performance blockchain apps and solutions for today’s digital world.

Key Skills to Look for When You Hire Blockchain App Developers

If you plan to hire dedicated blockchain developers, you need to assess their technical knowledge and soft skills to ensure you’re bringing on the right talent.

Solidity expertise

Developers with solid experience in Solidity are the best choice to develop smart contracts, particularly if you are going to be developing a project for Ethereum or something similar. Developers with Solidity experience are capable of creating secure, efficient, gas-optimized smart contracts, which will enable your app to perform and require the least amount of fuel cost. It would be a bonus to find developers who can demonstrate they are writing scalable and secure code and have a clear understanding of the possible vulnerabilities and ways to mitigate them.

Rust proficiency

If you are going to be developing a blockchain project with performance-driven criteria like Solana or any other product that uses Rust, you need to find developers with experience in Rust. Rust is ideal for building secure and efficient blockchain applications as it is performant and utilizes memory safety. A skilled developer in Rust will be able to build applications that have great performance and significantly reduce another key issue to address in any blockchain development, memory safety.

Web3.js mastery

Web 3.js experience is another critical skill set to be looking at when you are hiring blockchain app developers. Web3.js allows developers to interact with the Ethereum blockchain through a decentralized application (dApp). When looking for a developer, ensure they have utilized Web3.js with dApps to ensure there is a healthy connection between your dApp’s UI and the Ethereum network’s communication with Web3 wallets (like MetaMask) to connect to Ethereum nodes.

Problem-solving abilities

Beyond technical experience, problem-solving abilities are critical. Developing blockchain applications introduces lots of complex challenges that can be unpredictable. A good developer will have to dedicate and think outside the box to find an efficient solution to issues encountered during the development process. This is why it is assistance, problem-solving is what will turn a good developer into a great developer.

Communication skills

Equally important are the communication abilities of the developer. Blockchain projects will often require developers to collaborate with other teams, like front-end developers, back-end developers, designers, and business stakeholders, in the development process. Developers who can communicate both clearly and positively will contribute to healthy team dynamics and encourage work efficiency.

Where to Find Top Blockchain Developers

Freelance Platforms

Freelancer Platforms like Upwork, Fiverr, letsremotify, and Freelancer are excellent options if you want to hire remote blockchain developers on a project basis. You can review their portfolios and client feedback ratings to ensure that they have the skill levels necessary to fit the criteria of your blockchain project.

Blockchain-Specific Job Boards

Blockchain-specific job Boards like CryptoJobs and AngelList are set up solely for blockchain positions and will attract developers who have the necessary skills and expertise in the relevant blockchain technologies (Such as Solidity, Rust, Web3.js, etc.).

Blockchain Development Agencies

Blockchain Development Agencies employ teams of vetted professionals for larger and more complex projects. You may want to consider an agency if you are looking for a more efficient development process and an assurance of a full suite of skills and experience involved.

Open Source Projects and Communities

Open-source projects and Communities, such as GitHub, can be a great way to find developers who contribute to blockchain projects, as their contributions can change your insight into their skills, work ethic, and level of enthusiasm for blockchain development.

Red Flags When You Hire Blockchain App Developers

When you are looking to hire blockchain developers, you may also want to know what red flags to look for.

Lack of Solidity

Overall, the first red flag to look for is a lack of a Solidity background. Solidity is critical for developing smart contracts, especially on Ethereum. A developer who is unfamiliar with it, or does not want to work with it, simply will not be able to ensure secure and efficient solutions.

Lack of Real-World Experience

A developer who cannot show you at least 1 example of a real-world application or project of a blockchain application they have developed probably also should be a red flag. Real-world experience in the blockchain and DLT space shows that a developer not only has technical experience but also understands that past projects could have other complexities or challenges that would potentially arise.

Unfamiliar with Web3.js

Lastly, a developer who has no knowledge of Web3. JS may also be indicative of a developer who will struggle to develop smooth, functional, decentralized applications. Web3.js is essential for communicating between dApps and blockchain networks like Ethereum. Without this knowledge, the development cycle may be tedious and thus inefficient.

Note: Always stay vigilant for the above red flags so that you will be certain that the developer you hire is capable of developing what your project requires.

Interview Questions to Ask When You Hire Blockchain Developers

Here are some great interview questions to ask candidates for the blockchain developer role:

• What would you do to optimize a smart contract to save on gas fees and improve performance?
• What were the common vulnerabilities in smart contracts? What would you implement to predispose them?
• If working with Rust, what are the methods in place to ensure memory is safe while in use, and why is that important in a blockchain application?
• Can you discuss a time when you optimized a blockchain application (in Rust), for either performance or for speed?
• How do you ensure smooth interaction with the Ethereum blockchain through Web3.js in a decentralized application?
• How do you handle the wallet integration [MetaMask] in a decentralized application?
• Talk me through the deployment process of a smart contract in a testnet, and your plan to secure it before it goes live?

How to Set Competitive Compensation for Blockchain Developers

When determining a fair, competitive rate for blockchain app developers, you should attract the best of the best. First, you want to look up market rates for types of skills users require, such as Solidity, Rust, and Web3.js, and adjust for location and experience. Generally, you pay higher rates to freelancers than you would to full-time developers, but they usually warrant the additional cost that gets pulled from the project funds.

Full-time developers will expect some salary in a certain form of a salary plus an equivalent benefits package. Most importantly, you want to look for token or share equity that is related to the blockchain project, as a salary and options will help align their success with your project, which ultimately improves developer buy-in and hopefully longevity within the project. You will probably want to incorporate incentives for token and/or equity into compensation models so that you offer a full package that a skilled developer considers attractive.
