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 devastating hacks: reentrancy stole 600M$ from Ronin in 2022, overflow 320M$ Poly Network.

  • 80% of audits reveal critical vulns in juniors.

  • Poorly optimized gas inflates costs x10 on mainnet, hindering DeFi ROI.

  • Projects stalled, funds lost, reputation ruined.

  • Our training eliminates these risks with proven audits, 40% gas savings, secure deployment.

  • Invest 28h to secure millions, avoid 95% standard pitfalls.

Program

Module 1Advanced Solidity Patterns: Libraries, Proxies (Remix, Hardhat)

Dive into patterns like factories and delegates, implement modular contracts with exercises on OpenZeppelin, optimize data structures for low gas, analyze DAO hack cases, produce a deployable proxy pattern, all in pairs for immediate feedback and maximum motivation.

Module 2Gas Optimization and Solidity Security: Basic Audits (Slither)

Learn to profile gas with Hardhat, rewrite loops and storage for 50% savings, test reentrancy attacks on real simulations, integrate checks-effects-interactions, generate automated audit reports, experience the thrill of contracts armored against 90% of common vulns.

Module 3Upgradable Contracts and Interactions: Multisig, Oracles (Foundry)

Build transparent upgrades with UUPS, integrate Chainlink oracles for off-chain data, simulate multisig wallets via Foundry tests, deploy to Sepolia testnet, exchange group feedback on real fails, leave with production-ready deliverables and boosted confidence.

Module 4Advanced Projects and DApps: E2E Testing, Deployment (Truffle)

Develop a full-stack DeFi with React frontend, test advanced fuzzing, audit peer-review live, deploy to mainnet via scripts, finalize professional portfolio, feel the power of mastered Solidity for impactful projects and accelerated careers.

Evaluation method

  • Daily quizzes, graded exercises, certified final project, personalized feedback.

Learning method

  • 70% intensive practice, 30% applied theory, real Ethereum cases, professional tools.

Methods, materials and delivery

The Advanced Solidity 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 Advanced Solidity 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.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Advanced Solidity 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.
