Don't let this gap widen
Without advanced Solidity expertise, your smart contracts expose you to devastating hacks: reentrancy stole 600M$ from Ronin in 2022, overflow 320M$ Poly Network.
80% of audits reveal critical vulns in juniors.
Poorly optimized gas inflates costs x10 on mainnet, hindering DeFi ROI.
Projects stalled, funds lost, reputation ruined.
Our training eliminates these risks with proven audits, 40% gas savings, secure deployment.
Invest 28h to secure millions, avoid 95% standard pitfalls.
The Advanced Solidity Training - Secure and Optimized 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 Advanced Solidity Training - Secure and Optimized 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 Advanced Solidity Training - Secure and Optimized Smart Contracts training is carried out through:
