Blockchain systems that hold up when real money is on the line
We are a blockchain engineering firm, not a token shop. Senior engineers, audit-first, building since 2014. We design, build, and audit DeFi protocols, tokenization, stablecoin rails, wallets, and exchanges for fintech and Web3 teams.
Senior engineers. Audit-first. Building since 2014.
Not sure which service fits? Tell us what you are building →What we are, and what we are not
Plenty of shops will spin up a token over a weekend and disappear after launch. That is not us. We are the team founders bring in when the thing they are building holds real money, faces a regulator, or cannot afford an exploit.
What that means in practice:
→ We are engineers first
Senior people who have shipped to mainnet, not a sales team with a contractor bench.
→ We are audit-first
Security is designed in from week one and audited before anything goes live, not bolted on after.
→ We are not a retail crypto shop
We do not do meme tokens, pump projects, or make me the next Shiba Inu requests.
→ We stay through launch
We are there for deployment, the first incidents, and the months after, when production fires actually happen.
What we build. Pick the work you need.
Six capabilities, six pages. Start with the four lead practices or jump straight to a wallet or exchange build. Each links to its full page.
Also build:
How we work. The same model across every service.
→ Senior engineers only
The people who scope your project build it. No juniors learning on your budget.
→ Audit-first delivery
We design for security from week one and audit before launch, using Slither, Mythril, Echidna, Foundry, and manual review.
Slither · Mythril · Echidna · Foundry
→ You own everything
Your code, your repos, your keys, your IP, from day one. NDA on request.
→ Fixed-fee discovery first
You get a written architecture and price before committing to the build, so there are no surprises.
What we build on. Only the tech we have shipped.

Selected work. Range across services.
DeFi wallet from idea to launch
A multi-chain DeFi wallet taken from idea to launch in 10 weeks.
Pre-mainnet audit on a DeFi protocol

Frequently asked questions
A blockchain engineering firm. Blockchain and AI engineering is what we do, for fintech and Web3 teams. We do not run retail crypto or speculative token projects.
Freelancers build fast, ship broken, and disappear at handoff. We staff senior engineers, audit before launch, and stay through the first months in production.
Yes. AI agents and automation are a separate practice. Ask on the architecture review.
You do, from day one. We sign an NDA before discovery on request.
A 30-minute architecture review, then a fixed-fee discovery scope with a written plan and price. The build only begins once you sign that scope.
[NEEDS-VALIDATION: founder] We work with clients across the US, UAE, Singapore, the UK, and Canada.
Tell us what you are building. We will tell you how to build it right
Book a 30-minute architecture review. We will review your project, point you to the right approach, and send a written scope and price range. No sales pitch. If we are not the right fit, we will tell you who is.
NDA on request. Replies within 4 business hours, Monday to Friday.
