QA Report

[code423n4]

Solidity Version

Consider using the most recent version of solidity. 0.8.17 is already released and most contracts in the project specify ^0.7.6.

Consider using the same version of solidity in all files. A fixed version of solidity should be specified in all non-library files.

---

Most contracts in the project specify ^0.7.6.

pragma solidity ^0.7.6; https://github.com/code-423n4/2022-10-thegraph/tree/main/contracts/governance/Managed.sol#L3

But not all:

pragma solidity >=0.6.12 <0.8.0; https://github.com/code-423n4/2022-10-thegraph/tree/main/contracts/governance/IController.sol#L3

pragma solidity >=0.6.12 <0.8.0; https://github.com/code-423n4/2022-10-thegraph/tree/main/contracts/staking/IStakingData.sol#L3

Sensitive Terms

Avoid the use of sensitive terms in favor of neutral ones. Use allowlist rather than whitelist.

Missing NatSpec

Every function should have a short textual description.

In addition to the textual description, there should be a formal documentation for every parameter (@param).

There are A LOT of instances of this problem listed below. Quite a few borderline ok instances (missing formal parameters but described as text or obvious parameters) were not included in the report.
