Why this program matters

  • Without mastery of ERC-20, 78% of token projects suffer hacks costing on average 2,5 millions d'euros per incident, like the 600M$ lost on Ronin in 2022.

  • Untrained teams waste 50% more time on buggy redeployments, delaying DeFi launches.

  • In 2026, with MiCA, companies without secure tokens risk fines and exclusion from crypto markets.

  • Every delay widens a fatal competitive gap while rivals capture 30% more market share through flawless standards.

ERC-20 curriculum: 4 modules over 4 days

Module 1 : ERC-20 Fundamentals: Implementing the Standard Interface (Solidity, OpenZeppelin)

Dive into the complete ERC-20 interface with balanceOf, transfer, and approve; use OpenZeppelin libraries for secure code from the start; create your first testable fungible token; analyze real enterprise token cases; produce a deployable deliverable on Remix with integrated documentation; practical exercises to anchor professional skills in a continuous, value-adding learning flow.

Module 2 : Advanced ERC-20 Development: Adding Minting, Burning, and Ownership (Hardhat, Foundry)

Develop extended features like controlled minting and secure burning via Ownable; integrate roles with AccessControl for enterprise governance; code modular contracts with Hardhat for a smooth DevOps workflow; test locally with automated scripts; apply to a realistic DeFi red-thread project; generate 90% code coverage reports to validate certifiable skills.

Module 3 : ERC-20 Security: Audits, Reentrancy, and Upgrades (Slither, Mythril, Proxy Patterns)

Identify common vulnerabilities like reentrancy and overflow using Slither and Mythril; reinforce your ERC-20 contract with guards and checks-effects-interactions patterns; implement upgradable proxies for professional scalability; simulate attacks on your token; correct in real-time with expert feedback; produce a complete audit report and security plan; turn risks into sustainable competitive advantages.

Module 4 : ERC-20 Deployment: Layer2 Integrations and Monitoring (Etherscan, The Graph)

Deploy your ERC-20 token on Sepolia then mainnet via Hardhat and ethers.js; integrate with MetaMask wallets and DeFi applications; set up a The Graph subgraph to index transfer events; monitor live transactions on Etherscan; optimize gas for costs under 100k per mint; finalize the red-thread project with source code verification; leave with a live token and enterprise-ready skills.

Our method

How Learni guarantees the quality of your ERC-20 training

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.
