Why PR Reviews is a Vital Security Checkpoint
Before your next audit, before you deploy, before your code ever goes live, there’s an effective way to catch vulnerabilities early.
PR Reviews brings elite web3 security researchers directly into your development workflow, reviewing your pull requests as they happen. Delivered within days, not weeks, PR Reviews helps you identify security issues early, streamline your audit process, and ship with greater confidence.
The Problem: Security Needs to Be Continuous
Security audits are a critical part of launching in web3, but they often come at the end of the development cycle, when changes are hard to make and the cost of mistakes are higher.
And perhaps more importantly, code doesn’t stop evolving once an audit is complete. Features are added. Bugs are fixed. Business logic changes. All of this introduces new vulnerabilities that your audit simply wasn’t scoped to catch.
Relying on audits alone leaves a dangerous gap in your security posture. It’s not enough to secure your code once. Security needs to be continuous.
The Solution: Code Reviews at the Pace of Development
PR Reviews provides structured, on-demand security reviews of your pull requests, performed by vetted security researchers in the Immunefi network.
Each review is scoped to the changes in a specific PR and delivered as inline feedback directly in GitHub, typically within 24 to 72 hours.
Every time your team opens a pull request, you can ensure that security experts are reviewing your code, just like your own engineers, but with a focus on threat models, logic bugs, and attack surfaces. PR Reviews helps you reduce risk without slowing down development.
How It Works
Getting started is simple and fast:
- Install the Immunefi GitHub Application: Enable PR Reviews on selected repositories and branches.
- Submit Your Pull Request: When you open a pull request, the system detects it and begins the review process.
- Automatic Researcher Assignment: Using Immunefi’s HackerSync system, the PR is routed to a qualified researcher based on your code, scope, and past activity.
- Expert Review: The assigned researcher reviews your changes with a security-first mindset, identifying vulnerabilities and risks.
- Feedback Delivered in GitHub: Clear, actionable feedback is posted directly on your PR.
- Resolve and Merge: Address the findings, update your code, and ship with confidence.
When to Use It
PR Reviews is designed to be flexible and seamlessly integrate into your development workflow. It offers meaningful value across multiple stages of a project’s lifecycle, whether you're pre-launch, mid-sprint, or post-audit.
Before an Audit
Use PR Reviews to harden your codebase ahead of formal audits. By identifying and resolving issues early, you reduce audit scope, speed up turnaround time, and focus your audit team on higher-impact risks. This leads to better outcomes and fewer surprises.
During Ongoing Development
As your team ships new features or adjusts contract logic, PR Reviews offers a consistent layer of security without slowing velocity. It helps you identify bugs, risky patterns, or edge cases as they’re introduced, allowing for faster fixes and safer merges.
Between Audit Rounds
Many projects continue evolving between audit stages. PR Reviews helps validate updates, changes, or fixes made after your initial audit. It reduces the risk of regressions and ensures new code meets the same security standards as what’s already been reviewed.
Pre-Launch
In the days or weeks before a major deployment, PR Reviews provides targeted, high-signal feedback on final pull requests. This helps catch last-minute vulnerabilities or overlooked issues during a critical, high-pressure window when time is short and risks are high.
As Part of CI/CD
By embedding PR Reviews into your continuous integration process, you turn security into a routine part of development, just like testing or peer review. This makes it easier to scale secure practices across teams, contributors, and releases.
Understanding PR Reviews vs. Audits
By now, you might be thinking, “but how’s this different from an Immunefi Audit?”
And you won’t be alone in thinking that. Audits are critical, and PR Reviews doesn’t replace them. But the two processes are fundamentally discrete from one another:
Think of PR Reviews as the unit tests of your security process: repeatable, targeted, and built into your everyday workflow.
Trusted by Leading Onchain Security Teams
Leading web3 projects are already using PR Reviews to scale secure development. Here’s what some of them have to say:
"At Resolv, code quality and security are top priorities. While audits are essential, they can’t catch everything. Immunefi helps streamline the process, from PR reviews to continuous monitoring, through its bug bounty program and network of top researchers." — Fedor Polshchikov, Lead Software Engineer, Resolv
"It was easy to send a PR for review and the feedback was great. The only friction was setting up the app, but Immunefi made it easy. We look forward to working with them more." — Adriano DiLuzio, CTO, Bitcoin L2 Labs @ Stacks
