Why this program matters

Without expert Hardhat mastery, your gas deployments explode by 200-300%, causing 50k€ overruns on mainnet as seen in 65% of failed DeFi projects (ConsenSys 2023 report).
Incomplete tests lead to failed audits, with 40% of hacks exploiting undetected vulnerabilities and losing millions in funds (ex: 600M$ Ronin).
Manual CI/CD delays waste 3-4 weeks per release, blocking scalability against competitors.
Are you missing the expertise to secure and optimize your Ethereum smart contracts starting today?

Program

Module 1Hardhat Configuration: Expert Multi-Chain Setup (hardhat.config.js, Advanced Plugins)

Dive into expert Hardhat configuration, install plugins like @nomicfoundation/hardhat-toolbox, create hardhat.config.js for Polygon and Optimism, test mainnet forks via practical exercises on anvil, generate first verification scripts, deploy a simple contract live to validate setup, while optimizing memory and speed for real projects.

Module 2Advanced Testing: Chai, Mocha, Coverage (EVM Tests, Fuzzing)

Master unit tests with Chai/Mocha, implement fuzzing via ethers, achieve 95% coverage on complex contracts, simulate DeFi scenarios like flashloans on Hardhat Network, debug gas leaks in real-time, produce automated coverage reports, apply to real NFT cases to boost code reliability.

Module 3Deployment and Optimization: Upgradable Scripts, Gas Tuning (ethers, upgrades)

Develop upgradable deployment scripts with @openzeppelin/hardhat-upgrades, tune gas via advanced optimizer, deploy to Sepolia/Goerli in batch, analyze costs via hardhat-gas-reporter, migrate legacy contracts, test automated rollbacks, deliver monitoring dashboard for internal audits, ideal for scaling your Ethereum dApps.

Module 4Expert Integrations: CI/CD, Foundry, Slither (GitHub Actions Pipelines)

Integrate Hardhat with Foundry for hybrid tests, launch automated Slither audits, configure complete GitHub Actions CI/CD, fork mainnet for live trading simulations, customize tasks for multisig wallets, deploy to Arbitrum in production-like environment, conclude with capstone DeFi project deployed and monitored, ready for your blockchain challenges.

Evaluation 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.

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.
