Learning objectives

  • Optimize smart contracts to reduce gas by 50%
  • Implement security audits against reentrancy and overflow
  • Develop upgradable contracts via proxy patterns
  • Integrate Chainlink oracles and Layer 2 solutions
  • Master advanced testing with fuzzing and invariant testing
  • Deploy on mainnet with multisig and monitoring
  • Analyze real hacks to strengthen your code

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 this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1Solidity Optimization: Gas Efficiency and Refactoring (Hardhat, Slither)

Dive into refactoring existing contracts, analyze gas with Hardhat benchmarks, implement storage packing and assembly to halve costs, perform exercises on real DeFi cases, produce an optimized deliverable ready for immediate deployment, while mastering the latest Solidity 0.8.24 features.

Module 2Advanced Solidity Security: Audits and Vulnerabilities (Slither, Mythril)

Identify reentrancy, flash loans, and oracle manipulation using Slither, simulate attacks on your own contracts, code custom guards and emergency stops, analyze 10 famous hacks like Ronin, generate a complete audit report as a deliverable, boost your expertise for bulletproof contracts.

Module 3Expert Solidity Patterns: Upgrades and Scalability (OpenZeppelin, L2)

Deploy UUPS and transparent proxies with OpenZeppelin, migrate live contracts without downtime, integrate Arbitrum/Optimism to scale, code minimalist factories and clones, test in workshop on production scenarios, deliver a functional upgradable pattern, propel your projects towards industrialization.

Module 4Solidity Testing, Deployment, and Monitoring (Foundry, Tenderly)

Master fuzzing and invariants with Foundry, integrate secure Chainlink oracles, deploy via Gnosis multisig, configure Tenderly alerts for anomalies, simulate mainnet forks for realistic tests, produce a complete monitoring dashboard, finalize with a peer-review audit, ready for your critical missions.

Evaluation method

  • Daily technical quizzes, daily projects, simulated final audit, 360° feedback

Learning method

  • Hands-on projects on real cases, collaborative workshops, immediate expert feedback

Methods, materials and delivery

The Solidity Expert Training - Develop Impenetrable 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 - Develop Impenetrable 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 - Develop Impenetrable 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.
