Jow Software · Remote
We build the parts below the smart-contract line — consensus, networking, cryptography, wallets, and node infrastructure — and the AI tooling that helps teams ship faster. For early-stage and growing companies.
Services
01 / lead practice
Layer-1 work below the smart-contract line: the node, the network, the cryptography, and the wallets that talk to it.
02
Practical AI that ships: product features built on LLMs, and engineering teams that get real leverage from coding agents.
03
Senior engineering for the parts of the product that have to be right the first time.
Engagements
Architecture and protocol design reviews, security-minded code review, and a sounding board for hard technical calls.
A defined deliverable, scoped up front: a protocol feature, a wallet, an agent workflow, an MVP. Shipped, tested, documented.
A senior engineer inside your team part-time, in your standups and your repo, until the work no longer needs one.
Every engagement is scoped per project. Tell us what you need and we'll propose a shape.
Selected work
Full node for a privacy-focused cryptocurrency: consensus, P2P networking, mempool, and the wallet, with Rust cryptography under a TypeScript node.
Threshold multisig primitives based on FROST with authenticated participant communication, plus signing on Ledger hardware in embedded Rust.
Caching HTTP server that lets fully private light wallets run on nearly any device without a local node. Protobuf light blocks, OpenAPI endpoints.
Mobile wallet with a native Rust core compiled for iOS and Android, wired to the light-client stack.
Process
01
Thirty minutes on what you're building and where it's stuck.
02
A written plan: deliverables, risks, and how we'll know it's done.
03
Short cycles, working code early, progress you can run yourself.
04
Docs, tests, and a team that can own it without us.
