QBT Labs is a crypto market making firm and AI payment infrastructure company. We run trading desks, ship open-source protocols, and build the payment layer for autonomous agents.
On the market making side, we provide 24/7 liquidity across centralized exchanges — MEXC, Gate.io, Bitget, and Kraken. We manage spreads, maintain order book depth, and handle inventory risk for token projects that need reliable markets. No wash trading, no opaque token loans, no black boxes.
On the payments side, we're building the infrastructure that lets AI agents transact autonomously. Our x402 implementation enables HTTP 402 machine-to-machine payments. AMP delivers high-throughput payment channels across chains. Both are open source, MIT licensed, and production-tested.
We're not consultants. We don't build custom projects for clients. We operate trading infrastructure, ship products, and open-source everything we can.
Founder
Engineer turned operator. Previously Lead Engineer at Indigo Protocol — Cardano's leading synthetic assets platform — where he built the core blockchain indexer, production APIs, and multi-language SDKs processing millions of transactions daily.
Founded QBT Labs to build what didn't exist: open-source market making infrastructure that token projects can run themselves, and payment protocols that let AI agents operate financially without human intervention.
Now runs market making operations across 4 exchanges, leads development on the x402 and AMP payment protocols, and maintains the OpenMM trading stack used by quantitative traders and AI agents.
Open-source products powering market making and AI agent payments.
TypeScript-first trading toolkit for algorithmic market making across multiple exchanges. Grid strategies, inventory management, risk controls, and a unified connector interface for MEXC, Gate.io, Bitget, and Kraken. Funded by Cardano Project Catalyst.
Model Context Protocol server with 13+ tools giving AI agents direct access to market data, order execution, portfolio tracking, and grid strategies. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.
Everything we build is open-source. Not as a marketing strategy — as a core belief.
Every line of our trading and payment infrastructure is public. No hidden fees, no opaque algorithms, no black boxes.
Open code means more eyes finding bugs. Our infrastructure is battle-tested by the community, not just our team.
The best tools are built with their users. Contributors shape our roadmap, report issues, and push the ecosystem forward.
Don't trust us. Read the code. Verify the logic. Run it yourself. That's how trust should work in crypto.
