Why this program matters

Without mastering Hardhat, 65% of Solidity deployments fail in production, wasting 5k€ in unnecessary fees per project, 3-month delays on DApp launches, avoidable external audits at 20k€, hacks like Ronin (625M$ lost) due to faulty tests, teams stuck on buggy configs, loss of competitiveness against trained rivals.
Invest 21 hours to secure your chains, scale without crashes, and recoup in weeks via reliable deployments.

Program

Module 1Hardhat Configuration: Project Setup, Solidity Compilation (Tools, Configs, Tasks)

Dive into quick Hardhat installation, configure hardhat.config.js for your Ethereum project, compile your first Solidity smart contracts with automated checks, explore CLI tasks for a smooth workflow, complete practical exercises on a simple DApp, produce your first configured deliverable ready to scale, and experience the power of a professional environment from day 1.

Module 2Advanced Hardhat Testing: Mocha/Chai Scripts, Mock Data (Unit Tests, Integration)

Master writing unit and integration tests with Chai and Mocha in Hardhat, simulate complex blockchain scenarios via mocks, run coverage reports for 100% code coverage, refine assertions on events and transactions, apply to concrete cases like an ERC20 token, generate detailed reports as deliverables, and boost your development confidence with infallible tests.

Module 3Deployment and Advanced Features: Plugins, ethers.js Scripts (Deploys, Upgrades, Debugging)

Deploy your contracts on Sepolia and mainnet via upgradable Hardhat scripts, integrate plugins like Hardhat-ethers for smooth interactions, optimize gas with automated analyses, debug live with traces and console, automate upgrades via OpenZeppelin, test on real enterprise cases, deliver a portfolio of deployable scripts, and emerge ready to lead professional blockchain projects.

Skills assessment methods

Assessment of skills acquired during the Training Hardhat - Deploy Professional Ethereum Smart Contracts program is performed through:

During training: case studies, hands-on labs and professional scenarios
End of training: self-assessment questionnaire and skills evaluation by the trainer
After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

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

Which tools are used in Hardhat training?+

Hands-on work runs on tools, configs, tasks, unit Tests, integration and deploys. Those tools come from the Hardhat program itself, delivered on site over 3 days, so participants practise on the stack they will use at work.

What can participants do after Hardhat training?+

They can set up a complete Hardhat environment for Ethereum projects, write and run advanced tests with Chai and Mocha and deploy smart contracts on testnets and mainnet. Those are the stated objectives of the Hardhat program at Intermediate level, checked by the end-of-session assessment.

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

Day 1: Hardhat Configuration: Project Setup, Solidity Compilation (Tools, Configs, Tasks). Day 2: Advanced Hardhat Testing: Mocha/Chai Scripts, Mock Data (Unit Tests, Integration). Day 3: Deployment and Advanced Features: Plugins, ethers.js Scripts (Deploys, Upgrades, Debugging). The Hardhat program runs over 3 days, delivered on site.

How is Hardhat training assessed?+

Assessment relies on daily technical quizzes, final deployed DApp project and code reviews by trainer. Learni issues a completion certificate together with the individual assessment report at the end of the Hardhat program, which an L&D team can file as evidence.

How much does Hardhat training cost per participant?+

Hardhat training is priced on quote. The amount depends on headcount, format and how far the syllabus is tailored to your team. A detailed quote is sent within one business day, and team pricing covers the whole group from the second participant.

How long does Hardhat training take?+

3 days, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.

Who pays for Hardhat training?+

Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.

What do participants need to know before Hardhat training?+

Basic knowledge of Solidity, Node.js, npm, and Ethereum development.

Is a certificate issued after Hardhat training?+

Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
