-> Le contrat `FGC42Forge.sol` sera ajouté à l’étape 3. Le dossier contient encore l’exemple **Counter** généré par `npx hardhat --init`.
+### BEP-20 vs `ERC20` dans le code

+- **Rendu / soutenance :** token **BEP-20** sur **BNB Smart Chain Testnet** (chainId 97).
+- **Code :** héritage **OpenZeppelin `ERC20`** — norme EVM identique en pratique ; pas de bibliothèque `BEP20` séparée.
+- **Après deploy :** BscScan classera le contrat en **BEP-20** ; le source reste `import {ERC20} from "@openzeppelin/contracts/..."`.

+> Le dossier peut encore contenir l’exemple **Counter** (template Hardhat) en attendant nettoyage.
