Don't let this gap widen
Why this program matters
Without mastery of application development on Polygon, your smart contracts are exposed to critical vulnerabilities, like 68% of security incidents on Ethereum layer 2.
This generates average losses of 200 000 € per exploited breach, not to mention wasted gas fees reaching 15 000 € monthly for inefficient deployments.
Companies stagnate, losing 40% of market share to agile Web3 competitors.
Every quarter without solid skills creates an irrecoverable delay on multi-million opportunities.
Program
Module 1Introduction to Polygon and Environment Setup
Presentation of the Polygon blockchain, architecture and consensus, study of advantages compared to Ethereum, exploration of use cases (NFT, DeFi, gaming). Hands-on with wallets (Metamask), creating a Polygon account, installation of necessary SDKs (Node.js, Hardhat, Truffle), configuration of the Testnet network.
Module 2Writing and Deploying Smart Contracts with Polygon

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.
You meet the trainer beforehand

- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
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.
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.
