Audit findings are submitted to this repo.
Unless otherwise discussed, this repo will be made public after audit completion, sponsor review, judging, and issue mitigation window.
Contributors to this repo: prior to report publication, please review the Agreements & Disclosures issue.
Note that when the repo is public, after all issues are mitigated, your comments will be publicly visible; they may also be included in your C4 audit report.
Sponsors have three critical tasks in the audit process: Reviewing the two lists of curated issues, and once you have mitigated your findings, sharing those mitigations.
Note: It’s important to be sure to only review issues from the curated lists. There are two lists of curated issues to review, which filter out unsatisfactory issues that don't require your attention.
This curated list will shorten as you work. View the original, longer list →
For each curated High or Medium risk finding, please:
sponsor confirmed
, meaning: "Yes, this is a problem and we intend to fix it."sponsor disputed
, meaning either: "We cannot duplicate this issue" or "We disagree that this is an issue at all."sponsor acknowledged
, meaning: "Yes, technically the issue is correct, but we are not going to resolve it for xyz reasons."Add any necessary comments explaining your rationale for your evaluation of the issue.
Note: Adding or changing labels other than those in this list will be automatically reverted by our bot, which will note the change in a comment on the issue.
If you believe a finding is technically correct but disagree with the listed severity, leave a comment indicating your reasoning for the judge to review. For a detailed breakdown of severity criteria and how to estimate risk, please refer to the judging criteria in our documentation.
Judges have the ultimate discretion in determining validity and severity of issues, as well as whether/how issues are considered duplicates. However, sponsor input is a significant criterion.

disputed label
to any reports that you think should be completely disregarded by the judge, i.e. the report contains no valid findings at all.When you have finished labeling and responding to findings, drop the C4 team a note in your private Discord backroom channel and let us know you've completed the sponsor review process. At this point, we will pass the repo over to the judge to review your feedback while you work on mitigations.
Note: this section does not need to be completed in order to finalize judging. You can continue work on mitigations while the judge finalizes their decisions and even beyond that. Ultimately we won't publish the final audit report until you give us the OK.
For each finding you have confirmed, you will want to mitigate the issue before the contest report is made public.
Most C4 mitigation reviews focus exclusively on reviewing mitigations of High and Medium risk findings. Therefore, QA and Gas mitigations should be done in a separate branch. If you want your mitigation review to include QA or Gas-related PRs, please reach out to C4 staff and let’s chat!
If several findings are inextricably related (e.g. two potential exploits of the same underlying issue, etc.), you may create a single PR for the related findings.
This will allow for complete transparency in showing the work of mitigating the issues found in the contest. If the issue in question has duplicates, please link to your PR from the open/primary issue.
