Learning objectives

  • Optimize gas for scalable smart contracts on Ethereum Layer 2.
  • Implement advanced DAO governance with multisig and timelocks.
  • Audit zero-day vulnerabilities via fuzzing and formal verification.
  • Develop complex DeFi protocols with Chainlink oracles.
  • Integrate proxy upgrades for secure upgradable contracts.
  • Master inline assemblies for extreme performance.
  • Build NFT marketplaces with EIP-2981 royalties.

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without advanced Solidity expertise, 70% of smart contracts suffer exploits like Ronin (625M$ stolen) or Poly Network (611M$).

  • Excessive gas inflates costs by 50% on Layer 2, missed audits expose to reentrancy (The DAO, 50M$).

  • Miss proxy upgrades, your DAOs lock on irrecoverable bugs.

  • Lose 40% competitiveness against certified devs.

  • Invest 28h to secure millions, scale DeFi flawlessly, dominate Web3 audits.

Program

Module 1Advanced Solidity: expert syntax, libraries and patterns (Hardhat, Foundry)

Dive into inline assemblies, custom errors and optimized storage, code reusable libraries to reduce gas by 40%, test via Foundry with intensive fuzzing, analyze patterns like diamond proxy on real Uniswap V3 cases, produce a deliverable: gas-efficient library deployed on testnet.

Module 2Gas Optimization and Scalability: Layer 2, rollups (Optimism, Arbitrum)

Master EIP-4844 blobs and ERC-4337 account abstraction, refactor contracts for zk-rollups, simulate gas wars with Hardhat exercises, integrate blobs for cheap data, measure gains up to 90% on Polygon, deliverable: optimized contract deployed on Sepolia with performance report.

Module 3Expert Security: audits, reentrancy guards, formal methods (Slither, Echidna)

Detect sandwich attacks and MEV via Slither scans, implement emergency pauses and Gnosis multisig, fuzz with Echidna on 1000+ scenarios, audit protocols like Aave flashloans, simulate Ronin hacks (625M$ lost), deliverable: full DeFi contract audit with fixes.

Module 4Advanced Projects: DeFi, DAO, NFT (Chainlink, OpenZeppelin Upgrades)

Build yield farm with Chainlink oracles, deploy upgradable DAO via OpenZeppelin, integrate EIP-2612 permits for gasless approvals, test end-to-end on Anvil mainnet fork, challenge on NFT fractional ownership, deliverable: complete DeFi protocol with governance, deployed and pitched in groups.

Evaluation method

  • Daily technical quizzes on Solidity V0.8+.
  • Graded practical exercises with expert feedback.
  • Final DeFi project defense (50% of grade).

Learning method

  • Active methods: 80% practice, 20% theory.
  • Real exercises on mainnet forks.
  • Pair challenges for hack simulations.

Methods, materials and delivery

The Solidity Expert Training - Develop Secure Smart Contracts program is delivered onsite or remote (blended-learning, e-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 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.

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

Skills assessment methods

Assessment of skills acquired during the Solidity Expert Training - Develop 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 eligible for corporate training budgets and employer-funded plans.

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.
