Missing Project-Specific Source Code for Full Audit
The provided source code only includes OpenZeppelin's abstract ERC20 contract and its interfaces. The specific implementation of the 'Lighter' token, which would inherit from this base and define its unique functionalities (e.g., `_mint`, `_burn`, custom modifiers, or other business logic), was not included in the scope of this audit. Without the full implementation, a comprehensive security assessment of the 'Lighter' token cannot be performed, as critical vulnerabilities often arise from custom logic and interactions.
