Low Risk Issues

[L‑1] Critical functions should be controlled by time locks

It is a good practice to give time for users to react and adjust to critical changes. A timelock provides more guarantees and reduces the level of trust required, thus decreasing risk for users. It also indicates that the project is legitimate (less risk of a malicious owner making a sandwich attack on a user).

[L‑2] Owner can renounce Ownership

Typically, the contract’s owner is the account that deploys the contract. As a result, the owner is able to perform certain privileged activities.

The Openzeppelin’s Ownable used in this project contract implements renounceOwnership. This can represent a certain risk if the ownership is renounced for any other reason than by design. Renouncing ownership will leave the contract without an owner, thereby removing any functionality that is only available to the owner.

[L‑3] Missing storage gap for upgradable contracts

See description of this storage variable. While some contracts may not currently be sub-classed, adding the variable now protects against forgetting to add it in the future.

[L‑4] Use Ownable2Step instead of Ownable

Ownable2Step
and Ownable2StepUpgradeable prevent the contract ownership from mistakenly being transferred to an address that cannot handle it (e.g. due to a typo in the address), by requiring that the recipient of the owner permissions actively accept via a contract call of its own.
