We build signing, custody, and high-performance backend infrastructure for trading and on-chain teams.

What we build
A policy-based signer for your bots and your agents. You hold the keys. A signature is produced only when your policy is satisfied, and every request is decoded into something a person can actually read before it gets approved.
One slow path in Python, Node, or Go, moved to Rust. We benchmark it before and we benchmark it after, on your data. You get both numbers.
One or two Rust engineers embedded in your team. Your repo, your board, your review queue. Hourly or monthly.
Selected work
A signing daemon that sits between your automation and your keys. Bots get exactly the authority they were granted, decoded into something a person can read, and nothing more.
The security and throughput problems here are the same ones a trading desk has: hold credentials no operator should see, drive thousands of authenticated sessions without tripping rate limits, and keep the whole surface behind a boundary that fails closed.
Same four stages every time, whether the job is three weeks or six months.
A call, then a written scope. Goals, constraints, the failure modes that matter, and a definition of done we both sign off on.
Architecture and milestones agreed before any code is written. Risks get named while they are still cheap to fix.
Milestone delivery against a branch you can see. Progress is visible weekly, not revealed at the end.
Documentation, runbooks, and a deployment your team can operate without us. We stay reachable through your launch window.
Most of our work sits on a hot path or next to a private key. Rust is the one mainstream language that gives us both things we need: no garbage collector pausing a latency-sensitive service, and a compiler that refuses to ship the class of memory bugs that turn into a disclosure.
It is not the right answer everywhere. When a Python service is already fast enough, we will tell you that and leave it alone.
If it holds keys or it runs hot, it gets written in Rust.
Small on purpose. You talk to the people writing the code.
