There are upgradable contracts in the Castello coin project and can be deployed under proxies. The proxy admin can upgrade current version contracts to new version contracts.

The user should be aware that the Castello coin contracts are upgradable.

Upgradable Contracts

`AccessControlUpgradeable` is only used in the contract `TokenPolygon`, contract `Token` do not have any privileged functions depends on the AccessControl. 

`AccessControlUpgradeable` Is Not Used In The Contract `Token`

Without any other mint out of the token initialize. All of the tokens are sent to the contract deployer when deploying the contract. This could be a centralization risk as the deployer can distribute tokens without obtaining the consensus of the community.

Initial Token Distribution

The name and symbol of the token is not solidified in its contract code. They depends on the deployment parameters which could be changed.

Unsolidified Token Name And Symbol

A local variable is shadowing another component defined elsewhere.

File: castello/Token.sol (Line 10, Function `Token.constructor`)
```solidity
        string memory _name,
        string memory _symbol,
```


Shadowing Local Variable

In the contract `TokenPolygon`, the role `DEFAULT_ADMIN_ROLE` has authority over the following functionalities:
- reannounce the CHILD_CHAIN_MANAGER
- set CHILD_CHAIN_MANAGER role admin

Any compromise to the `DEFAULT_ADMIN_ROLE` account may allow a hacker to take advantage of this authority and change the polygon child chain manager.

Centralization Related Risks

In the contract `UpgradableProxy` the role `ProxyOwner` has authority over the functions shown in the diagram below:
- transferProxyOwnership
- updateImplementation
- updateAndCall

Any compromise to the `ProxyOwner` account may allow a hacker to take advantage of this authority and change the ownership or the implementation.
