The program, module by module
Module 1 — Blockchain Fundamentals
Understand what actually changes with a blockchain — consensus, blocks, wallets — before a first transaction on an Ethereum testnet.
Module 2 — Writing Smart Contracts in Solidity
Move from theory to a contract that compiles: syntax, visibility, require(), events.
Module 3 — Deploying to Ethereum with Hardhat/Foundry
Compile, test, then deploy a contract to a testnet, in that order, never reversed.
Module 4 — Smart Contract Security
Spot reentrancy, integer overflow, and broken access control before an irreversible deployment makes them costly.
Module 5 — Building a dApp with Web3
Connect a frontend to a deployed contract with ethers.js and MetaMask, including error handling.
Module 6 — Final Project and Certification
CertificationAssemble an audited contract, security, and frontend into a functional dApp on testnet, graded by a mentor.

Three levels, from simplest to most demanding. Each one only claims what it actually verifies.
Attendance certificate
Earned by: Modules followed
Proves: You followed the track — no graded assessment.
Certificate of achievement
Earned by: Full track completed on the platform, final project included, and final exam passed
Proves: Your knowledge and your final project, evaluated by the platform.
Field Practice Validated distinction
Earned by: A field challenge completed after the exam, in a real situation, with evidence
Proves: A CoursTech mentor reviewed and validated a genuine real-world application.
The distinction is added to your certificate of achievement — it never replaces it: nothing off-platform ever blocks the certificate itself.
Mentor support and validation: handled on request, within 72 business hours. If no mentor is active, the distinction stays open for 12 months as planned: no learner is penalized.
Mentor sessions: limited spots, on request. Reply within 48 h.
