Don't let this gap widen
Without advanced Solidity expertise, your smart contracts expose you to massive hacks: 3.7 billion $ lost in 2022 on Ethereum alone.
Miss 80% of internal audits, incur external fees of 20-50k€ per contract, deploy with 2x more gas blocking DeFi scalability.
Competitors dominate with optimized L2, you stagnate on expensive mainnet.
Reentrancy or flashloan exploits drain treasuries: hacked DAOs lose 100% of funds.
Invest 28 hours or pay the high price in irreversible losses and missed opportunities.
Dive into the latest Solidity 0.8 features, explore expert design patterns like factories and delegates, code modular contracts with OpenZeppelin, complete exercises on proxies, produce a functional tested deliverable locally, while optimizing from the start for maximum efficiency.
Analyze and reduce gas via Hardhat benchmarks, implement optimized storage and inline assembly, track leaks with Slither, simulate high-load real cases, generate performance reports, transform your contracts into scalable machines ready for DeFi production.
Detect advanced reentrancy and oracle manipulation via manual audits, deploy Echidna fuzzing on your code, validate with formal verifiers, dissect famous hacks like Ronin (625M$), produce a complete audit report, secure your DApps against zero-day threats.
Deploy on Optimism/Arbitrum with upgradability, integrate Chainlink VRF for secure randomness, configure Gnosis Safe multisig, test cross-chain bridges, finalize a complete DeFi project deployed, leave with an expert toolbox to dominate the Ethereum ecosystem.
The Solidity Expert Training - Secure and Optimized Smart Contracts program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.
For the smooth delivery of the Solidity Expert Training - Secure and Optimized Smart Contracts program, the following equipment is required:
For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

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.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
