Learning objectives

  • Master Chainlink oracles to connect blockchains and off-chain data
  • Develop professional and secure Chainlink jobs in a business context
  • Implement reliable data flows with Chainlink VRF and Automation
  • Design certifying smart contracts integrating Chainlink for DeFi
  • Optimize Chainlink performance in real blockchain projects
  • Deploy scalable and attack-resistant Chainlink solutions

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

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 1Chainlink Fundamentals: Installation and First Oracles (nodes, CLI, base contracts)

Quick installation of the Chainlink node locally and on testnet, getting started with the Chainlink CLI to create your first oracle job, exploration of standard ERC contracts like Consumer and Aggregator, practical exercises on simple HTTP requests to external APIs, development of a tester smart contract that retrieves real-time prices, with debugging and log optimization for smooth professional integration.

Module 2Advanced Chainlink Jobs: Data Flows and Feeds (TOML, bridges, external adapters)

Detailed configuration of TOML jobs for complex multi-source flows, integration of external adapters for custom data such as weather or sports, use of Chainlink feeds for decentralized prices in DeFi, exercises on business cases with simulated network failures, creation of cross-chain bridges for Ethereum and Polygon, unit tests and performance monitoring for certified reliability.

Module 3Chainlink Integration: VRF and Automation in Smart Contracts (Solidity, upgrades)

Implementation of Chainlink VRF for secure randomization in games and NFTs, contract automation with Keepers for reliable periodic executions, advanced Solidity development with proxy patterns for upgrades without downtime, practical cases on DeFi lending protocols connected to oracles, attack simulations and resilience, production of mainnet-deployable deliverables with gas optimization for reduced business costs.

Module 4Chainlink Deployment: Security, Scaling, and Production (monitoring, audits, multi-chain)

Production deployment on Ethereum, BSC, and Arbitrum with Grafana/Prometheus monitoring, security audits of jobs against off-chain manipulations, horizontal scaling of nodes for high availability, exercises on multi-chain CCIP for secure cross-chain transfers, migration plan from legacy oracles to Chainlink 2.0, finalization of a capstone project with performance report and business roadmap.

Evaluation method

  • Multiple-choice quiz to validate Chainlink skills at the end of the training
  • Continuous assessment through practical exercises and simulated jobs
  • Defense of the capstone DeFi oracle project before the expert trainer

Learning method

  • Courses led by an active Chainlink expert trainer
  • Practical exercises on real business blockchain cases
  • Progressive capstone project with testnet deployment
  • Complete course materials and official Chainlink resources

Methods, materials and delivery

The Chainlink Training - Integrating Secure Decentralized Oracles program is delivered onsite or remote (blended-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.

Equipment required

For the smooth delivery of the Chainlink Training - Integrating Secure Decentralized Oracles program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

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.

Skills assessment methods

Assessment of skills acquired during the Chainlink Training - Integrating Secure Decentralized Oracles program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

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.
