• Celebrating our 2025 open-source contributions Last year, our engineers submitted over 375 pull requests that were merged into non-Trail of Bits repositories, touching more than 90 projects from cryptography libraries to the Rust compiler. • This work reflects one of our driving values: “share what others can use.” The measure isn’t whether you share something, but whether it’s actually useful to someone else. • This principle is why we publish handbooks, write blog posts, and release tools like Claude skills, Slither, Buttercup, and Anamorpher. • But this value isn’t limited to our own projects; we also share our efforts with the wider open-source community. • When we hit limitations in tools we depend on, we fix them upstream. • When we find ways to make the software ecosystem more secure, we contribute those improvements.

Article Summaries:

  • Trail of Bits highlights its 2025 open‑source impact, noting that engineers submitted over 375 pull requests merged into more than 90 external projects, from cryptography libraries to the Rust compiler. The company stresses its core value of “share what others can use,” publishing handbooks, blogs, and tools such as Claude skills, Slither, Buttercup, and Anamorpher. Key contributions include the Sigstore rekor‑monitor (supported by OpenSSF), 20+ merged PRs to Rust’s Clippy and compiler, 28 PRs to pyca/cryptography (funded by Alpha‑Omega), and work on the Haskell‑based hevm EVM. These efforts aim to improve security and usability for the wider open‑source community.
