Why this program matters

Without expert Hardhat mastery, your Solidity deployments risk critical bugs: 40% of DeFi hacks stem from insufficient testing, gas overconsumption up to 10k€ per failed transaction, external audits billed at 50k€ to fix avoidable vulnerabilities.
Lose weeks on manual debugging on faulty forks, miss mainnet opportunities due to unoptimized scripts, and expose your projects to costly flash loan attacks.
In 2023, 2M$ were lost on Ethereum from poor gas optimization.
Invest 28h to secure your contracts, accelerate your launches and boost your blockchain career.

Program

Module 1Hardhat Configuration: Expert Environment and Custom Scripts

Dive into advanced Hardhat configuration, install plugins like hardhat-deploy and etherscan, create custom npm tasks for daily workflows, complete practical exercises on a real DeFi project, generate optimized configurations for multi-networks, and produce your first ultra-performant Solidity compilation script ready for production.

Module 2Hardhat Testing: Advanced Tests and Coverage

Master Chai, Mocha, and Hardhat Network for powerful unit tests, implement external contract mocks, achieve 100% coverage with exercises on vulnerable smart contracts, simulate flash loan attacks, generate automated reports, and validate tests through real-world cases inspired by actual audits, boosting your code reliability.

Module 3Hardhat Deployment: Gas Optimization and Verification

Optimize gas with integrated Hardhat tools, deploy to testnets and mainnet via upgradable scripts, verify contracts live on Etherscan, analyze performance metrics on complex DApps, practice multi-chain deployments, and produce audit-ready deliverables, avoiding costly production pitfalls.

Module 4Hardhat Integrations: CI/CD, Forks, and Monitoring

Integrate Hardhat with GitHub Actions and Vercel for seamless CI/CD, fork mainnet for cost-free realistic tests, add Tenderly for advanced debugging, develop gas monitoring dashboards, complete a final project with ethers.js frontend, and deploy a full pipeline, transforming your skills into immediate professional assets.

Evaluation method

Daily practical projects, advanced technical quizzes, final smart contract audit, Hardhat expert certification.

Learning method

70% hands-on with real Ethereum cases, 30% applied theory, collaborative exercises in small groups.

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

Triple validation: technical, pedagogical, sectoral.
Minimum rating 4.8/5 over the last 12 sessions.

Step 2

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.

Step 3

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.

Step 4

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.

FAQ

Frequently asked questions

What can participants do after Hardhat training?+

They can set up a custom Hardhat environment with advanced plugins, develop automated unit and integration test suites and optimize gas and deploy to mainnet with secure scripts. Those are the stated objectives of the Hardhat program at Expert level, checked by the end-of-session assessment.

What does the Hardhat program cover, day by day?+

Day 1: Hardhat Configuration: Expert Environment and Custom Scripts. Day 2: Hardhat Testing: Advanced Tests and Coverage. Day 3: Hardhat Deployment: Gas Optimization and Verification. Day 4: Hardhat Integrations: CI/CD, Forks, and Monitoring. The Hardhat program runs over 4 days, delivered on site.
