Why this program matters

  • In 2024, DeFi hacks caused more than 3 billion euros in losses from unoptimized Solidity vulnerabilities, exposing companies to massive fund drains.

  • Without mastery of Solidity 2026, your smart contracts risk reentrancy or oracle manipulation exploits, leading to costly audits at 100k€+ and loss of customer trust.

  • Expert developers stagnate against Web3 competitors already deploying blobs and scalable L2s, threatening promotions and career shifts.

  • Invest in this certified training to secure your career and your company today.

Solidity training: access and practical arrangements

The Training Solidity 2026 - Mastering Advanced DeFi 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 Training Solidity 2026 - Mastering Advanced DeFi 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 Training Solidity 2026 - Mastering Advanced DeFi 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.

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.

Our method

How Learni guarantees the quality of your Solidity 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.

FAQ

Solidity: frequently asked questions

Which tools are used in Solidity 2026 training?+
Hands-on work runs on hardhat, foundry, blobs, uniswap V4, lending and chainlink oracles. Those tools come from the Solidity 2026 program itself, delivered on site over 3 days, so participants practise on the stack they will use at work.
What can participants do after Solidity 2026 training?+
They can master the new features of Solidity 2026 for ultra-high-performance enterprise smart contracts, develop secure and gas-optimized DeFi protocols with certifiable skills and implement advanced mechanisms like account abstraction and blobs for scalability.

3 days, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.
Who pays for Solidity 2026 training?+
Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.
What do participants need to know before Solidity 2026 training?+
Advanced mastery of Solidity 0.8+, development of complex smart contracts on Ethereum, knowledge of Hardhat and Foundry tools.
Is a certificate issued after Solidity 2026 training?+
