Is this an upgrade of an existing system? If so, which? And what are the main differences?
This is a complete ground-up implementation of a Solana protocol client. It was based on the Agave client (https://github.com/anza-xyz/agave), which is written in Rust, but this implementation is written from scratch in C.
Where do you suspect there may be bugs? Valuable aspects of this question are:
Which parts of the code are you most concerned about?
- Signing Tile (https://github.com/firedancer-io/firedancer/tree/v0.106.11814/src/disco/keyguard)
- QUIC Tile (https://github.com/firedancer-io/firedancer/tree/v0.106.11814/src/waltz/quic)
- Sandbox (https://github.com/firedancer-io/firedancer/tree/v0.106.11814/src/util/sandbox)
What attack vectors are you most concerned about?
- Any attack vector that results in the loss of funds
- Remote Code Execution, leading to compromise of validator key material or arbitrary transaction signing
- Denial of Service, leading to degradation or loss of service availability
- Global Denial of Service, leading to consensus failure, excessive forking, or chain halts
Which part(s) of the system do you want whitehats to attempt to break the most?
- Signature Verification Tile (Denial of Service / RCE / Arbitrary Signing)
- Network and QUIC Tiles (Denial of Service / RCE)
- Sandbox Escape or Violation (Abusing the sandbox or violation of sandbox policies for unexpected outcomes)
- Inconsistencies between Firedancer / Agave behavior that lead to unsafe outcomes.
Are there any assumed invariants that you want whitehats to attempt to break?
- If any tile is compromised, the sandbox should contain its effects on that tile. It should not allow the compromise to significantly impact other tiles and/or the system.
Would you consider any bug report requiring their involvement to be out of scope as long as they operate within the privileges attributed to them?
- Any bug reports that assume a pre-existing compromise of the validator operating system, applications, or any administrative control over the operating system.
- Any bug dependent on exploiting vulnerabilities in the agave client codebase.
- Any bug reports that require social engineering or physical attack on a person or the system.
- Any bug reports that assume a malicious operator or the like.
- Any bug that is not exploitable on the latest stable and supported Linux distributions (Ubuntu, Debian, Fedora, or Red Hat Distributions).
- Any bug that is not focused on x86 architecture.
- Any bug that is not exploitable on the latest stable and supported GCC versions.
- Any bug that has an initial vector of compromise in a dependency.
- Any bug in a dependency that is not exclusive to Firedancer should instead be reported to the upstream repo. (For example, If you find a bug in Agave that also affects Agave, you should report it to the Agave bug bounty program instead).
What external dependencies are there?
Build Dependencies: perl, autoconf, gettext, automake, autopoint, flex, bison, build-essential, gcc-multilib, protobuf-compiler, llvm, lcov, libgmp-dev, cmake.
Where might whitehats confuse out-of-scope code to be in-scope?
Code exists in the repository, which is in development but not yet executed by the validator, while it currently leverages the Agave client for these functions - for example, src/flamenco/runtime/, src/ballet/sbpf/. Attempts have been made above to make this very clear in the file dump listing at the bottom of the scope table, but there may be some minor exceptions that we can clear up if there are questions.
Are there any unusual points about your protocol that may confuse whitehats?
TLS stack handwritten only contains the parts absolutely necessary for Firedancer
What is the test suite setup information?
- GitHub Actions: https://github.com/firedancer-io/firedancer/tree/main/.github/workflows
- Additionally, M1 fuzzing harnesses do exist in the main repo, you can find them with this command: find . -type f -name 'fuzz_.c' -path './src/'
- Fuzzing harnesses can be built with a modern Clang compiler (recommended: 17):
MACHINE=linux_clang_x86_64 EXTRAS="asan fuzz" make -j fuzz-test

Public Disclosure of Known Issues
Bug reports covering previously discovered bugs (listed below) are not eligible for a reward within this program. This includes known issues that the project is aware of but has consciously decided not to “fix,” necessary code changes, or any implemented operational mitigating procedures that can lessen potential risk.
- https://github.com/firedancer-io/firedancer/issues (any public issues before submission)
- https://github.com/firedancer-io/firedancer (any fixes in the main repo before submission)
Previous Audits
Firedancer v0.1 completed audit reports can be found at https://github.com/firedancer-io/audits. Any unfixed vulnerabilities mentioned in these reports are not eligible for a reward.
Any sandbox escape
Any bug leading to loss of funds or acceptance of forged / invalid signatures
Key compromise/exfiltration exploit chain
Process to process RCE between sandboxed tiles
Any bug leading Firedancer v0.1 to produce an invalid block or skip its leader slot
Consensus issues causing Firedancer v0.1 validators to fork
Liveness issues that cause Firedancer v0.1 validators to crash or be unavailable
Out of scope
These impacts are out of scope for this bug bounty program.
All Categories:
- Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
- Impacts caused by attacks requiring access to leaked keys/credentials
- Impacts caused by attacks requiring access to privileged addresses (governance, strategist) except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
- Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
- Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
- Best practice recommendations
- Feature requests
- Impacts on test files and configuration files unless stated otherwise in the bug bounty program
Websites and Apps
- Theoretical impacts without any proof or demonstration

- Impacts involving attacks requiring access to the local network of the victim

- Captcha bypass using OCR without impact demonstration
- CSRF with no state modifying security impact (e.g. logout CSRF)
- Impacts related to missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”) without demonstration of impact
