Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Discover the complete structure of the ERC-20 standard, its mandatory functions like transfer and balanceOf, through practical exercises on Remix IDE and OpenZeppelin libraries. Analyze real cases of failed tokens to identify common pitfalls, implement your first basic contract with integrated unit tests, and produce a functional deliverable ready for audit. This 7-hour session lays solid foundations for secure professional development.
Dive into Transfer and Approval events, add extensions like controlled minting and secure burning with Hardhat for the testing environment. Develop custom contracts integrating pausability and ownership via OpenZeppelin, perform massive transaction simulations, debug live with tracing tools, and generate code coverage reports. This intensive 7-hour day delivers practical skills for enterprise-grade tokens.
Identify common attacks like reentrancy or integer overflow on vulnerable ERC-20 contracts, use Slither and Mythril for automated audits. Strengthen your code with secure modifiers, implement multi-signature for admin, test with advanced fuzzing on Foundry, and write a complete audit report. This 7-hour day, focused on real cases of famous hacks, ensures resilient tokens for production deployment in the enterprise.
Deploy your ERC-20 tokens on Sepolia then Ethereum mainnet, monitor via Etherscan and Tenderly for gas-optimized simulations. Integrate with wallets like MetaMask, explore upgrades via UUPS proxies, measure and reduce gas costs by up to 40%, and finalize with verified contract certification. This concluding 7-hour session produces a live token ready for DeFi or NFT integration, with post-training support.

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.
