Why this program matters

Without mastery of ERC-721, 70 % of NFT smart contracts deployed on Ethereum present critical vulnerabilities, exposing projects to massive hacks like those that cost 1,7 milliard $ in 2022.
A single minting or transfer error generates an average of 150 000 € in lost gas fees and stolen assets, paralyzing blockchain projects.
Companies without expertise miss 50 % of NFT opportunities, seeing revenues drop 30 % while technical teams face obsolescence and restructurings.
Every month without solid skills, competitors capture the exploding market and threaten business survival.

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.
