Learning objectives

  • Master advanced Solidity syntax for creating professional smart contracts
  • Develop secure contracts with event management and optimized storage
  • Implement design patterns and libraries in Solidity for enterprise use
  • Optimize gas and audit vulnerabilities in certifying projects
  • Deploy smart contracts on testnets using Hardhat and Foundry tools
  • Integrate Solidity with frontends via Web3.js for decentralized applications

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 1Advanced Solidity Syntax: Data Types and Functions (Remix IDE, modifiers, visibility)

Dive into complex Solidity structures by creating your first intermediate contracts. Explore mappings, dynamic arrays, and structs to manage decentralized data. Define functions with modifiers for security. Practical exercises on business cases like a secure voting system. Use Remix IDE for live testing. Produce a functional contract with integrated documentation, immediately enhancing your blockchain skills.

Module 2Complex Solidity Contracts: Inheritance, Events, and Libraries (Hardhat, Slither)

Build multi-layered smart contracts by implementing inheritance for modular code reuse. Emit events to track blockchain transactions. Integrate custom libraries to optimize performance. Practical workshops on an advanced ERC20 token with controlled minting. Local deployment via Hardhat. Code analysis with Slither to detect early vulnerabilities. Obtain a deliverable ready for testnet, boosting your professional Solidity development expertise.

Module 3Solidity Security: Audits and Best Practices (Foundry, reentrancy guards)

Master common Solidity pitfalls like reentrancy attacks and overflows through realistic simulations. Apply guards and checks-effects-interactions patterns. Use Foundry for comprehensive unit tests. Manual and automated audits of existing company contracts. Real-world cases inspired by famous hacks like The DAO. Create an inviolable secure banking contract. Generate professional audit reports, transforming your projects into reliable assets for the certifying blockchain ecosystem.

Module 4Solidity Deployment and Integration: Testnets and Web3 (ethers.js, migration scripts)

Deploy your smart contracts on Sepolia testnet with automated Hardhat scripts. Interact with frontends via ethers.js for complete DApps. Optimize gas to reduce production costs. End-to-end tests on enterprise scenarios like an NFT marketplace. Monitoring with Etherscan. Finalize a decentralized red thread project. Deliver source code and tutorials for immediate autonomy, positioning your Solidity skills at an expert level for professional opportunities.

Evaluation method

  • Technical MCQ on Solidity and its vulnerabilities at the end of the training
  • Evaluation by audit of developed smart contracts
  • Presentation of the red thread project with testnet deployment

Learning method

  • Courses by Solidity expert trainer with blockchain production experience
  • Practical exercises on real Web3 company cases
  • Progressive 4-day Solidity red thread project
  • Complete Solidity course materials and GitHub resources

Methods, materials and delivery

The Solidity Training - Developing Secure 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 Training - Developing Secure 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 Training - Developing Secure 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.
