Infrastructure that keeps running after the enthusiasm runs out.
Chippr Robotics is an independent engineering company. We build financial infrastructure and the software underneath it, and we publish what we learn doing it.
What we build
Three projects, one discipline.
Write it to be read, test it in public, license it so someone else can pick it up, and don’t ship anything you’d be embarrassed to have audited.
Self-custody digital asset infrastructure
FairWins
Embedded wallets, policy-governed custody, payments and settlement, markets connectivity and compliance. The platform never takes custody: every action that moves value is signed by the holder’s own keys. Available white-label as tenant instances.
- Treasury lead Signed
- Finance Signed
- Operations Waiting
Execution client · Scala 3
fukuii
An execution-layer client for EVM networks, continuing IOHK’s Mantis: from a home mining rig to enterprise infrastructure.
Agent key containment
Sigil
Two-of-two threshold signing: one shard on a floppy disk, one on the agent’s device. Nothing signs until someone puts the disk in.
From the research blog
We work in public.
The research behind the products: protocol notes, design decisions and the reasoning we would otherwise only write in a pull request. All research →

How we work
Small on purpose: a few humans, many robots.
In public
The reasoning is readable by anyone.
The code, the issues and the reasoning are open. When something fails we say so, in the same place we said it would work.
Custody
Custody stays with the holder.
Our software never takes custody, and the parts that could are the parts we do not build.
Verifiable
Verifiable over impressive.
Every fukuii release ships with SLSA Level 3 provenance, a CycloneDX SBOM and a Cosign signature, so an operator can verify what they are running.
