In the contract `topup_v1`(Aptos), the role `admin` has authority over the functions shown below: - set_valid_coin(): setup whitelist token status - set_recv_addr(): setup token receiver address --- In `solana-pay` program, the role `ADMIN` has authority over the functions shown below: - withdraw(): withdraw tokens from the token account belongs to the program id --- In the contract `TopUpTron`, the role ` m_owner` has authority over the functions shown below: - withdraw(): withdraw native tokens from the contract - tokenWithdraw(): withdraw tokens from the contract - setValidToken(): setup whitelist token status - setRecvAddr(): setup token receiver address - changeOwner(): update `m_owner` address --- In the contract `TopUpV1`, the role `Manager` has authority over the functions shown below: - withdraw(): withdraw native tokens from the contract - tokenWithdraw(): withdraw tokens from the contract - setValidToken(): setup whitelist token status - setRecvAddr(): setup token receiver address - setupRole(): assign `MANAGER_ROLE` or `DEFAULT_ADMIN_ROLE` to an address In the contract `TopUpV1`, the role `DEFAULT_ADMIN_ROLE` has authority over the functions shown below: - grantRole(): assign `MANAGER_ROLE`, `DEFAULT_ADMIN_ROLE` or other role to an address - revokeRole(): revoke `MANAGER_ROLE`, `DEFAULT_ADMIN_ROLE` or other role from an address In the contract `TopUpV1`, the role `Owner` has authority over the functions shown below: - renounceOwnership(): Leaves the contract without owner. - transferOwnership(): Transfers ownership of the contract to a new account (`newOwner`). Any compromise of the privileged accounts could allow an attacker to exploit the authority, and potentially manipulate the contract functionalities.

The Aptos Move provides a code upgrade feature(with policy `compatible` by default) that allows deployed Move code to be replaced with the newer code based on the upgrade policy. Any compromise to the deployer account may allow a hacker to take advantage of this authority to control the implementation of the program, for example, burning tokens, which raises potential security risks. Reference: [Upgrading Move Code](https://aptos.dev/en/build/smart-contracts/book/package-upgrades) --- The Solana platform allows for the possibility of upgrading its programs, with the default upgrade authority being the entity responsible for deployment. In situations where the program has upgradability features and the account of the upgrade authority becomes compromised, there is the potential for an unauthorized and malicious update to the program. Reference: [Solana Update Program](https://solana.com/docs/programs/deploying#update-program) --- In the contract `TopUpV1`, the proxy admin has the authority to update the implementation contract behind the `TopUpV1` contract. Any compromise to the admin account may allow a hacker to take advantage of this authority and change the implementation contract which is pointed by proxy and therefore execute potential malicious functionality in the implementation contract.
