Our social commitment

A school kit donated to a child for every training

To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.

  • Backpack, notebooks and essential supplies
  • Distributed through our partner charities
  • Included, at no extra cost to you

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.

Don't let this gap widen

Why this program matters

  • Without advanced Solidity expertise, your smart contracts expose you to massive hacks: 3.7 billion $ lost in 2022 on Ethereum alone.

  • Miss 80% of internal audits, incur external fees of 20-50k€ per contract, deploy with 2x more gas blocking DeFi scalability.

  • Competitors dominate with optimized L2, you stagnate on expensive mainnet.

  • Reentrancy or flashloan exploits drain treasuries: hacked DAOs lose 100% of funds.

  • Invest 28 hours or pay the high price in irreversible losses and missed opportunities.

Program

Module 1Advanced Solidity Fundamentals: Patterns and Libraries (Hardhat, OpenZeppelin)

Dive into the latest Solidity 0.8 features, explore expert design patterns like factories and delegates, code modular contracts with OpenZeppelin, complete exercises on proxies, produce a functional tested deliverable locally, while optimizing from the start for maximum efficiency.

Module 2Gas Optimization and Performance: Slither Tools, EVM Profilers

Analyze and reduce gas via Hardhat benchmarks, implement optimized storage and inline assembly, track leaks with Slither, simulate high-load real cases, generate performance reports, transform your contracts into scalable machines ready for DeFi production.

Module 3Expert Solidity Security: Audits, Fuzzing and Formal (Mythril, Echidna)

Detect advanced reentrancy and oracle manipulation via manual audits, deploy Echidna fuzzing on your code, validate with formal verifiers, dissect famous hacks like Ronin (625M$), produce a complete audit report, secure your DApps against zero-day threats.

Module 4Advanced Deployment and Ecosystem: L2, Oracles, Multisig (Chainlink, Gnosis)

Deploy on Optimism/Arbitrum with upgradability, integrate Chainlink VRF for secure randomness, configure Gnosis Safe multisig, test cross-chain bridges, finalize a complete DeFi project deployed, leave with an expert toolbox to dominate the Ethereum ecosystem.

Evaluation method

  • Daily practical projects, paired final audit, technical quizzes, Qualiopi certification.

Learning method

  • 70% hands-on active pedagogy, pair coding workshops, individualized feedback.

Methods, materials and delivery

The Solidity Expert Training - Secure and Optimized Smart Contracts program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Solidity Expert Training - Secure and Optimized Smart Contracts program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Solidity Expert Training - Secure and Optimized 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.

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.
