Don't let this gap widen
Without expert Solidity mastery, your smart contracts risk massive hacks: 70% of DeFi exploits come from advanced vulnerabilities like reentrancy or oracle manipulation, causing losses of 3.7 billion $ in 2022 (Chainalysis).
Imagine losing 625M$ like Ronin or 600M$ like Poly Network due to gas negligence or faulty upgrades.
Wary clients flee unaudited protocols, stalling your career.
With our experts, avoid these pitfalls, deploy confidently, and seize seven-figure blockchain opportunities.
The Solidity Expert Training - Master Secure Smart Contracts training is delivered in-person or remotely (blended-learning, e-learning, virtual classroom, remote in-person). At Learni, a Qualiopi-certified training organization, each program is designed to maximize skills acquisition, regardless of the training mode chosen.
The trainer alternates between demonstrative, interrogative, and active methods (through practical exercises and/or real-world scenarios). This pedagogical approach ensures concrete and directly applicable learning in the workplace.
To ensure the quality of the Solidity Expert Training - Master Secure Smart Contracts training, Learni provides the following teaching resources:
For in-house training at a location external to Learni, the client ensures and commits to having all necessary teaching materials (IT equipment, internet connection...) for the proper conduct of the training action in accordance with the prerequisites indicated in the communicated training program.
The assessment of skills acquired during the Solidity Expert Training - Master Secure Smart Contracts training is carried out through:
