The contract uses OpenZeppelin's `Ownable` pattern with a single owner address that has complete control over critical functions. This creates a single point of failure where the compromise or loss of the owner's private key can severely impact the protocol.

Risk scenarios include:

- Owner key compromise leading to malicious actions

- Loss of owner key resulting in inability to manage protocol

- Social engineering attacks targeting the owner

- No redundancy or recovery mechanisms

All critical functions use onlyOwner modifier

​

Functions controlled by single owner:

- setAllowedSellToken()

- emergencyWithdrawERC20()

- withdrawFees()

- Any future administrative functions

modifier onlyOwner() {

_checkOwner();

_;

}

Implement multi-signature wallet ownership using Gnosis Safe or similar

Add role-based access control with separate roles for different functions

Implement governance mechanisms for critical decisions

Add owner rotation capabilities with proper transition
