Centralized Control of Critical Roles
The `DEFAULT_ADMIN_ROLE` and `MINTER_ROLE` are initially granted to a single hardcoded External Owned Account (EOA) at address `0x70F279Fa72c82110A0bB4745D6283B790190c33F`. This creates a single point of failure for the contract's access control (7.3 Access Control) and economic stability (7.4 Economic). If this EOA's private key is compromised, an attacker would gain full control over role management (granting/revoking any role) and token minting, potentially minting tokens up to the `MAX_SUPPLY` and devaluing existing tokens.
