QBX Token

In the contract `qbx` the role `_owner` has authority over the functions shown in the diagram below.  - `pause()`: This function pauses all token transfers, mints, and burns. It leverages the `Pausable` extension to enforce that no ERC20 operations can occur while the contract is paused. **Privileged role**: Only the contract owner can call this function. - `unpause()`: This function unpauses the contract, allowing token transfers, mints, and burns to resume. This is particularly critical after a pause has been implemented to stabilize the token's operations or address security issues. **Privileged role**: Only the contract owner can call this function. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and update the sensitive settings and execute sensitive functions of the project

The linked function `transfer()` is declared to return a value, but the function body does not return anything. Consequently, the function will return a default value, which could cause issues when used.
