Why this program matters

  • Without mastery of secure smart contract development with Ink!

  • on Substrate and Polkadot, 70 % of deployed contracts contain critical vulnerabilities that attackers can exploit.

  • These flaws generate average losses of 450 000 € per incident, plus 80 000 € in emergency audits and weeks of lost development.

  • Your company exposes itself to massive hacks, legal action, and irreversible erosion of investor confidence.

  • Every month without advanced expertise, risks accumulate and threaten the viability of your blockchain projects.

Our method

How Learni guarantees the quality of your Secure 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.
