Learning objectives

  • Master the advanced Ethers.js APIs for interacting with smart contracts in production
  • Develop professional skills in managing providers and wallets for robust dApps
  • Implement secure versioning strategies with Ethers.js in an enterprise environment
  • Optimize Ethereum transactions via Ethers.js to minimize gas costs
  • Design certifying decentralized architectures integrating Ethers.js and DevOps tools
  • Deploy scalable blockchain applications in teams with a focus on certifying training

The Learni story

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

Why this program matters

  • 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.

Program

Module 1Advanced Ethers.js Fundamentals: Provider Configuration and Secure Connections (Wallets, RPC)

Dive into advanced Ethers.js provider configuration, explore custom RPC nodes, and integrate hardware wallets like Ledger. Complete practical exercises on connecting to testnets, simulate production environments with robust error handling, and produce an operational blockchain monitoring script to validate professional training skills.

Module 2Ethers.js Smart Contract Management: ABI, Encoding, and Dynamic Calls (Debugging Tools)

Deepen interactions with complex ABIs using Ethers.js, code overloaded function calls and filtered events, apply gas tracing debugging techniques, work on real DeFi contract cases, generate typed TypeScript interfaces for seamless enterprise integration, and deliver a reusable contract wrapper to boost DevOps skills.

Module 3Advanced Ethers.js Transactions: Batching, Gas Optimization, and Multisig (Real Simulations)

Master Ethers.js transaction batching to scale dApps, optimize gas with dynamic estimates and EIP-1559, implement Gnosis multisig wallets, test on mainnet forks via Hardhat, analyze network congestion scenarios, and produce a production-ready transaction manager module to strengthen certifying training expertise.

Module 4Ethers.js DevOps Integration: CI/CD with Git, Subgraphs, and Monitoring (Automated Pipelines)

Integrate Ethers.js into GitHub Actions and GitLab CI pipelines for deployment versioning, deploy TheGraph subgraphs for optimized querying, configure Prometheus alerts on blockchain events, automate end-to-end tests with Ethers.js scripts, collaborate on a fullstack decentralized project, and deliver a complete Git repo with security hooks for professional upskilling.

Module 5Scalable Ethers.js Architectures: L2, IPFS, and Advanced Security (Final Certifying Project)

Design dApps on Layer 2 like Optimism with custom Ethers.js providers, integrate IPFS storage for NFT metadata, strengthen security against reentrancy and frontrunning, review a group capstone project with code audit, deploy live on testnet, and obtain Qualiopi certification validating advanced blockchain DevOps skills for enterprise.

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

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.
Step 4

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.
