Smart Contracts - Blockchain Technology Applied shows you how self-executing contracts work and why they matter. Smart contracts are the backbone of decentralized systems, powering applications in finance, healthcare, gaming and beyond, and they change how trust, efficiency and transparency work online.

You start with the fundamentals - what smart contracts are, their history, and the platforms that run them - then get hands-on with Solidity: writing, testing and deploying contracts on Ethereum, navigating legal and regulatory questions, and optimizing gas fees. Finally you integrate real-world data with oracles, use advanced Solidity, and audit contracts for vulnerabilities - across 43 short video lessons, 9 readings and 12 assignments.

It's course 1 of Board Infinity's Blockchain Technology Applied specialization on Coursera, for developers, entrepreneurs and tech enthusiasts.

The bridge that brings real-world data into contracts that can't fetch it on their own.

Security

Auditing tools

Tools and practices for finding common vulnerabilities before a contract goes live.

Skills you leave with

Fundamentals

What smart contracts are, where they run, and the rules around them.

  • Smart contract structure & functions
  • Platform evaluation
  • Legal & regulatory compliance
  • Use-case analysis

Development skills

Writing contracts that compile, pass tests and deploy.

  • Solidity programming
  • Testing & debugging
  • Ethereum deployment
  • Gas optimization

Security & advanced

The difference between a demo contract and one people can trust.

08 FAQ

Common questions

Everything learners ask before enrolling, answered plainly.

About the course

You'll learn smart contracts end to end. Module one covers what they are, their history, platforms like Ethereum and EOS, and the legal and regulatory side. Module two covers Solidity, setting up a development environment, writing, testing and debugging a contract, and deploying to an Ethereum test network with gas optimization and security best practices. Module three covers oracles, advanced Solidity, and security auditing.

Coursera lists this as a beginner-level course, and it's the first course in the specialization. Solidity is introduced from its basics and the development environment is set up step by step. Some general programming familiarity will make module two easier, but the course is written for developers, entrepreneurs and tech enthusiasts alike.

The current enrollment options and price for your region are shown on the Coursera course page. The course is included with a Coursera Plus subscription, and Coursera's financial aid is available for eligible learners. Enrollment also includes the whole Blockchain Technology Applied specialization track.

About 13 hours of total learning across 3 modules, 43 video lessons, 9 readings and 12 assignments. Coursera estimates 1 week at 10 hours a week. It's fully self-paced - deadlines flex around your schedule.

No. The course deploys contracts to an Ethereum test network, which exists so developers can practise deployment without using real funds. You'll also learn how gas fees work and how to optimize contracts to reduce them.

Yes - this page is Board Infinity's own overview of our course. Enrollment, payment, video lessons, grading and the certificate all happen on Coursera, where the course is hosted. Think of this page as the detailed tour before you head there.

Career & certificate

Yes. Completing the graded quizzes earns you a shareable certificate from Board Infinity, issued through Coursera with its own verification link. You can add it to your LinkedIn profile, resume or CV, and the same completed work counts toward the full specialization certificate.

It's the foundation for smart contract developer, blockchain developer and DApp developer roles, and for security-focused roles like smart contract auditor. The legal and platform modules also help product managers and consultants who work with blockchain projects.

Two ways. The certificate goes in your LinkedIn Licenses & Certifications section via Coursera's one-click add. Just as valuable is naming what you can do: a line like “Wrote, tested and deployed Solidity smart contracts to an Ethereum test network, with gas optimization and security auditing” gives interviewers something concrete to ask about.

Each module has three practice quizzes, one per lesson, and a one-hour graded quiz at the end - 12 assignments in all. A reading after each lesson goes further into topics like Solidity, deployment and smart contract auditing.

The next two courses of the specialization: Hands-on DApp Design and Development Using Web3 Tools (course 2, ~12 hours) to build applications on top of your contracts, and Deep Dive into Cryptography (course 3, ~13 hours) for the cryptography that secures blockchain systems. Enrolling in this course automatically enrolls you in the specialization.
