Don't let this gap widen
Why this program matters
Without expert Hardhat mastery, 70% of deployments fail due to faulty configs, exposing you to hacks like the 600M$ lost in 2022 on Ronin (test errors).
Your gas-inefficient contracts cost 40% more in fees, delaying launches and losing investors.
Manual audits miss 25% of reentrancy vulnerabilities, leading to lawsuits and reputational losses.
In production, lack of CI/CD multiplies bugs by 5, with critical DeFi downtimes.
Invest 35h to avoid these pitfalls, deploy securely and scalably starting tomorrow.
Program
Module 1Hardhat Installation: Advanced Configuration (Node.js, plugins, hardhat.config.js)
Install Hardhat in a real Ethereum project, configure hardhat.config.js with custom networks, advanced compilers, explore essential plugins like @nomicfoundation/hardhat-toolbox, perform your first compile and local test, generate coverage reports, while resolving concrete multi-chain cases to boost your productivity from day 1.
Module 2Hardhat Deployment Scripts: Automation and Upgrades (ethers.js, upgrades)
Create dynamic deployment scripts with HRE, manage environment variables, implement proxy upgrades with OpenZeppelin, deploy to Sepolia and Goerli, verify transactions via Etherscan API, produce verifiable artifacts, apply to a complete DeFi DApp to master scalable and secure deployments.
Module 3Advanced Hardhat Testing: Chai, Mocha, Fixtures (unit tests, fuzzing)
Develop exhaustive test suites with Hardhat fixtures, integrate Chai matchers for precise assertions, simulate mainnet forks, test reentrancy and gas limits, generate detailed HTML reports, debug with stack traces, apply to ERC-721/1155 contracts for 100% coverage and early vulnerability detection.
Module 4Hardhat Plugins and Optimizations: Gas, Verification, Storage (slither, tenderly)
Integrate gas-reporter and storage-layout plugins, optimize contracts via Slither static analysis, verify source code on Etherscan, configure Tenderly for simulations, profile gas on mainnet fork, produce automated audits, test on a lending protocol to reduce costs by 30% and accelerate Web3 launches.
Module 5Hardhat CI/CD and Production: GitHub Actions, Monitoring (tenderly, thegraph)
Automate CI/CD pipelines with GitHub Actions and Hardhat tasks, integrate Tenderly and The Graph monitoring, deploy with zero downtime, manage multisig via Gnosis Safe, simulate advanced attacks, finalize a capstone project deployed and indexed, leave with a pro workflow to scale smart contracts in production flawlessly.
Evaluation method
- Daily practical projects, technical quizzes, final deployed smart contract audit, Qualiopi certification.
Learning method

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
