Why this program matters

  • Ignoring smart contracts in 2026 exposes you to massive losses: in 2023, DeFi hacks drained 3.7 billion dollars according to Chainalysis, ruining projects and careers.

  • Without Solidity skills, 70% of novice developers miss Web3 opportunities, where salaries explode to +150k€/an.

  • Your company risks obsolescence in the face of massive tokenization, losing 20-30% market share.

  • Master them now to secure assets and boost professional competitiveness.

Smart Contracts curriculum: 4 modules over 4 days

Module 1 : Blockchain Fundamentals: Introduction to Ethereum Smart Contracts (Solidity, Remix IDE)

Discover the basics of Ethereum blockchain, the principles of smart contracts and their role in Web3, through interactive demonstrations on Remix IDE. Explore gas transactions and addresses, complete your first exercises reading existing contracts, analyze concrete cases like ERC-20 tokens, and obtain clear deliverables such as a personal blockchain operation diagram to consolidate your beginner knowledge in professional training.

Module 2 : Solidity Syntax: First Simple Smart Contracts (Variables, Functions, Events)

Dive into Solidity syntax to create your first smart contracts. Code basic functions, manage storage and memory variables, implement events for traceability, practice with guided exercises on simple voting contracts, test locally via Hardhat, analyze common beginner errors, and produce a functional contract as a deliverable to strengthen your professional blockchain development skills.

Module 3 : Advanced Smart Contract Development: Data Structures, Modifiers, Inheritance (Solidity 2026)

Build complex smart contracts with mappings, structs, and dynamic arrays. Apply modifiers for security, explore inheritance and OpenZeppelin libraries, develop a practical ERC-721 NFT contract, integrate unit tests with Foundry, simulate Web3 interactions via ethers.js, fix reentrancy vulnerabilities, and generate a deployable code portfolio as a certified deliverable for your enterprise progression.

Module 4 : Deployment and DeFi Integration: Security, Testnets, Web3 (Sepolia, 2026 Tools)

Deploy your smart contracts on Sepolia testnets, integrate them into Web3 dApps with WalletConnect, explore basic DeFi protocols like Uniswap V3, audit security with Slither and Mythril, optimize gas for 2026, build a complete final DeFi project, receive personalized expert feedback, export verified contracts to Etherscan, and obtain a professional smart contracts competency certificate to enhance your enterprise training.

How Smart Contracts skills are assessed

  • Daily interactive quizzes to validate beginner knowledge
  • Final DeFi project: deployed and audited smart contract

Our method

How Learni guarantees the quality of your Smart Contracts training

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.
