If you're interested in harnessing blockchain technology, consider hiring smart contract developers.

Smart contract developers can help you test, debug, and create smart contracts — blockchain algorithms that automatically execute, document, or control legally-relevant actions and events according to the terms of an agreement or contract. However, they can also help you develop blockchain projects, protect users from threat actors, and implement automatic transactions.

Read this guide to learn more about smart contract developers, what they do, and how much they make. We'll also cover how to hire a smart contract developer.

What is a Smart Contract Developer?

A smart contract developer is a programmer who writes, tests, and debugs smart contracts — blockchain network algorithms that run when certain conditions are met. Many companies hire them to create and implement blockchain platforms.

Smart contracts play a vital role in blockchain transactions. Every time someone performs an action on a blockchain, the blockchain automatically uses smart contracts to execute an agreement so that every participant immediately knows the outcome, without time loss and intermediary involvement.

Most smart contracts operate based "if/when... then..." statements. However, that doesn't necessarily mean they're simple. Depending on your needs, a smart contract can have as many stipulations as required.

What Can Smart Contracts Be Used For:

You can use smart contracts for many applications, including:

• Personal investor accounts: Smart contract programmers can use smart contracts to create a front-end or user interface (UI) for personal investors' accounts. Users can then use the UI to interact with smart contracts or blockchains directly.
• Fundraising: You can also use smart contracts for crowdfunding projects. Smart contract developers can do this by creating a smart contract and issuing tokens on the blockchain to attract the capital and interest of investors.
• Decentralized applications (dApps): dApps, also stylized as dapps, operate on a blockchain. Like traditional apps, dApps can be created for various purposes, such as social media, finance, and gaming. Because they run on a blockchain, they are free from the interference and control of a single authority. Other benefits of dApps include lack of censorship, flexible development, and the safeguarding of user privacy.
• Cryptoprocessing: Smart contracts can enable the acceptance of cryptocurrency for your personal account or project. Programmers can do this via crypto payment processing, internal billing, and token accrual.
• Insurance apps: If you're running an insurance company, smart contract coders can use smart contracts to automate your services and policies, increase transparency, reduce claims processing and administrative costs, and prevent fraud. They can also use smart contracts to automate claims functions and payments.

How To Develop Smart Contracts

Blockchain participants and smart contract developers develop smart contracts by establishing the terms and stipulations of their smart contract. They accomplish this by:

1. Determining how their data and transactions are represented on the blockchain
2. Agreeing on the "if/when... then..." statements
3. Pinpointing possible exceptions
4. Creating a dispute resolution framework

Once the participants have agreed on the contract terms, the smart contract developers can start coding. Many smart contract programmers write their code from scratch, but organizations increasingly provide web interfaces, templates, and other tools to streamline and simplify smart contract creation.

Finally, the smart contract developers test and debug the smart contract to ensure it's working. The main way to debug smart contracts is caveman debugging, where developers print to check the contract flow and inspect variables' values.

What Does a Smart Contract Developer Do?

A smart contract programmer is primarily responsible for creating, testing, debugging, and deploying smart contracts. Additional responsibilities include:

• Creating architecture for newly developed or existing software solutions using smart contracts and blockchain platforms
• Creating nontemplate smart contracts
• Integrating smart contracts into existing solutions
• Establishing smart contract audits using manual and automated tools
• Developing a comprehensive and effective economic model for your cryptocurrency project

What is a Smart Contract Developers Salary

Like other cryptocurrency professionals, smart contract developers typically earn high salaries.

The average smart contract salary depends on location. According to Web3, the average junior or entry-level smart contract developer in North America earns $140,000 to $200,000 annually. Here's the breakdown of smart contract developer salaries in other parts of the world:

• Remote: $150,000 to $250,000 annually
• South America: $112,000 to $150,000 annually
• Europe: $80,000 to $135,000 annually
• Oceania: $75,000 to $100,000 annually
• Asia: $68,000 to $150,000 annually
• Africa: $64,000 to $75,000 annually

The averages also differ significantly within continents due to seniority, with inexperienced coders making less than their experienced counterparts.

Entry-Level Salary for Smart Contract Developers

Junior or entry-level smart contract developers have under three years of working experience. As such, they tend to make less than their senior colleagues. A quick Google search reveals that most junior smart contract engineer salaries range from $80,000 to $120,000.

They are typically responsible for the following:

• Writing smart contracts in one or more programming languages, typically Rust or Solidity
• Testing and deploying applications across multiple blockchains
• Applying computer science and mathematical concepts to design and implement dApps

Most companies expect junior and entry-level contract programmers to have the following skills:

• Some knowledge of smart contract languages, such as Rust and Solidity
• Strong communication and teamwork skills
• The ability to work remotely
• Some knowledge of cryptography — cryptography is the study and practice of techniques for secure communication in the face of adversarial behavior
