Solidity Programming Brief Overview

Solidity is a contract-oriented programming language for writing smart contracts on the Ethereum blockchain. Solidity is a statically typed, imperative programming language that supports inheritance, libraries, and complex user-defined types.

It was influenced by C++, Python, and JavaScript and is designed to target the Ethereum Virtual Machine (EVM).

The popularity of Solidity developers for hire is growing together with blockchain. According to Fortune Business Insights, the global blockchain market is supposed to grow to $163.83 billion by 2029 compared to $7.18 billion in 2022. The main driving factor for developing cryptographic ledger solutions is rising identity and data theft activities.

In 2021, the next industries shared the global blockchain market:

Who is an Expert Solidity Developer?

The best Solidity developers are experienced with blockchain technology and the development of smart contracts. They should also have experience developing on the Ethereum platform, as well as EOS and Tron. The ideal candidate has a background in Cardano development.

It’s important for an expert Solidity developer to also have practical knowledge in other areas such as:

  • Cryptography
  • Distributed systems architecture
  • Mathematical algorithms and data structures

Let’s Check which Developer Fits You!

Technical Skills of a Solidity Developer

Basic Solidity knowledge is not enough to start coding smart contracts for an Ethereum dapp. A developer needs to know how to interact with web3.js, truffle framework, and get implementation for developing decentralized applications using Solidity programming language:

Development Environment Setup.

The first step for any Solidity developer to begin the work on your project is to install a development environment. The goal is to install the following:

  • web3.js to communicate with smart contracts from JavaScript-based applications such as Metamask or Truffle Console and easily access deployed contracts from within our code base.

Solidity for developing smart contracts in Ethereum.

Ethereum is a blockchain-based platform that allows developers to create decentralized applications (DApps). These DApps use smart contracts to function like regular apps without centralized servers. That means a Solidity developer will be able to build applications like Uber, where no one controls all the data about riders, drivers, and payments; instead, each person has full control over their own information from start to finish.

Web3.js for interacting with Ethereum Blockchain.

Web3.js is a JavaScript API that allows interaction with the Ethereum blockchain. It allows the creation of a Web3 object, which lets you use provider functions. These providers are specific to different networks (i.e., testnet or mainnet), so an instance of web3 needs to be created for each network you want to interact with. Multiple events can be listened to for your application to respond accordingly when certain actions occur on the blockchain and its smart contracts, such as when a transaction has been sent from one wallet address over another.

Truffle Framework for building decentralized applications (Dapps).

Truffle is a development environment, testing framework, and asset pipeline for Ethereum. It’s an open-source project aiming to make life easier for an Ethereum developer. For example, a Solidity developer can use the built-in web3 provider feature of Truffle to communicate with your deployed contracts via the console or through JavaScript code.

Geth implementation for understanding the Ethereum Client Software.

Geth is the command line interface for running a full Ethereum node implemented in Go. It is also used to create and interact with smart contracts. Geth is the most popular Ethereum client, commanding over 60% of hash power on the Ethereum network.

ProCoders know how these technical skills are important for every project, as you can see that all technologies are connected to each other. If a Solidity developer lacks knowledge of at least one of them, it can affect your project drastically.

Benefits of Hiring Solidity Developers for Your Project

When you hire a Solidity developer for your project, you will get the following benefits:

  • Solidity developers can understand complex financial transactions, concepts, and environments. This is because they are highly skilled in their field. They also have an understanding of the blockchain technology that powers Ethereum.
  • Solidity developers can create smart contracts for your project, enabling you to use Ethereum as a tool for your company or business. You can also use it in case if you mull over how to create a Dapp that will interact with other apps on the network through API calls or anything else that comes up while writing code in Solidity.
  • Solidity programmers can enhance your blockchain-based project. They can help you build new products, but they also have the potential to improve your existing ones by implementing blockchain technology in them.

Tips to Hire a Solidity Developer

Hiring a Solidity developer can be difficult. Although the demand for Solidity developers is high these days, it’s hard to find real specialists. It especially feels in Western Europe and the USA where the demand is higher than the offer, which increases prices. ProCoders have put together some tips for finding and working with a Solidity developer that you can trust!

Offshoring

If you are looking for a Solidity developer for hire, you can hire them on an offshore basis. The best part about hiring someone offshore is that you will save money and time in terms of salaries and the hiring process. The hiring process in the offshore model is much faster than when you try to hire a local developer. Besides, you will not have to worry about office space or other expenses like bonuses to salaries, taxes, and other costs associated with hiring someone locally.

Outsource

There’s always an opportunity not to dive deep into the details of Solidity development, smart contracts, and blockchain and to outsource the work to solidity professionals. The advantage of this method is that it will save you time in learning all the fine points of the blockchain works and allow you to focus on management, marketing, etc.

However, with outsourcing, there is no guarantee that the code will be tested and approved before delivery. You will need t trust your vendor t the full value, as you will have almost no control over the development process. Unfortunately, after that, everything depends on your luck: the possibility that your vendor will deliver code without testing it first which can cause problems down the road regarding deployment and integration testing remains.

Outstaff

Usually, when you decide to hire solidity developers, you will face many vendors offering their outstaffing services, including ProCoders. From our clients experience, there’re some reasons why they hire solidity experts on an outstaffing basis:

  • Hiring a solidity developer on an outstaffing basis allows access to a pool of professionals at a low cost.
  • You can easily find a skilled professional or two for your project who will be able to complete it in time and with high quality.
  • The best part is that your company does not have to invest any money or time in hiring these professionals, as they are provided to you by your vendor.
  • You will have full control over what your developers do, as outstaffing supposes integrating a team into your business processes and development like they are your in-house workers.
Find out How the Outstaffing Model Fits You

T&M vs. Fixed prices.

You will likely see two contracts and pricing structures: time and materials (T&M) and fixed price. The former means you pay for the work hourly, while the latter is a set price for a defined scope of work. Both have their pros and cons, but your choice may depend on what type of project you’re doing.

The traditional T&M model allows you the most flexibility in determining the scope of your Solidity project. However, if there are any changes in scope or problems occur during development that requires additional work by your Solidity developer, they should be compensated accordingly under this model; however, unlike fixed-price models where extra hours/days would be charged above what was agreed upon initially without adding additional value as part of normal business operations (such as dealing with bugs), they won’t receive anything extra besides what was originally agreed upon unless there are specific changes within their original agreement (which could mean higher costs).

Steps to Hire Solidity Coders Quickly for Blockchain Development with ProCoders

The hiring process begins with competition between candidates and outstaffing companies. You should have a plan for this process so that everything goes smoothly.

At ProCoders, we thoroughly check our Solidity specialists, and clients feel this. Want to discover how we do that? Read further!

Step 5. (optional) Interview with a client

The client can ask absolutely anything they want. Or they can even ask nothing if they fully trust our judgments about the developer.

Interview Questions to Ask When Hiring a Solidity Programmer

If you’re looking to hire a solidity programmer, you’ll want to ask them the right questions. These are some of the best questions to ask when hiring a solidity programmer:

  • What are the main differences between Solidity and other programming languages like Python, Java, or C++?
  • What is an enum? What are the restrictions on their use?
  • What is the function of the consensus algorithm?
  • What is a constant function in Solidity?
  • What is the concept of storage variables in Solidity?

How Can You Check if the Solidity Developer Fits your Project?

You know how difficult it is to find the right kind of developer for your project. ProCoders do because we’ve been through the same thing. So what do you do once you want to take this next step? Simple. You make a checklist that will lead you to finally finding the guy/gal for the job:

  • judge their skills by asking them to solve a problem using Solidity;
  • ask them about the latest changes in Ethereum. Solidity developers should know what’s going on in the Ethereum development world, which is important for security purposes;
  • make sure this person fits your personality profile before hiring them;
  • check what motivates them. A Solidity developer should be ready to dive deep into your project, not just to get a good salary.

How Much Does it Cost to Hire Solidity Developers?

The cost of Solidity developers varies from country to country, and sometimes these differences can be crucial. Just have a look (annual salaries are mentioned):

CountryJuniorMiddleSenior
Portugal$80,000$100,000$120,000
Croatia$34,000$55,000$85,000
Estonia$28,000$40,000$70,000
India$15,000$35,000$50,000

The UK$90,000$130,000$180,000
The USA$85,000$125,000$170,000

At the same time, you can consider hiring a professional from an outstaffing company, which will save your costs. For example, ProCoders have the next rates:

  • average annual salary of $80,000 per project (however, everything depends on your project complexity and tasks that should be done);
  • the average hourly rate of $29 per hour.

Keep in mind that outstaffing companies exclude all the hidden costs (hiring costs, insurance, costs for software and equipment, etc.), which drastically decreases the price compared to the one when you want to hire crypto developers for your in-house team.
