flintblocks is a small senior team. trading infrastructure, market-making systems and on-chain contracts for crypto-native funds — and consumer products (booking, POS, dashboards, marketplaces) for everyone else. you keep the code. you keep the edge.
we ship trading systems and consumer products from the same small senior pod. the disciplines feed each other — production-grade engineering shows up in both.
for crypto-native funds, prop desks, market makers and protocol teams. rust + c++ where it matters. solidity, vyper, move and anchor for contracts.
for everyone who needs a real product, not a SaaS rental. next.js + react native + postgres + stripe. same engineers as the trading infra side.
small surface area on purpose. every engagement is a small senior pod embedded with your team, shipping production code from day one.
co-located execution stacks, deterministic order routers, custom feed handlers. rust and c++ where it matters, written to your latency budget.
we don't sell a platform. we build yours and hand it over.
spread-capture strategies, inventory and hedging systems, post-trade attribution. we've quoted into majors and long-tail venues alike.
run by us as a service, or stood up inside your stack — your call.
production solidity, vyper, move and anchor. formally tested, fuzz'd, and shipped through real audits — not a stamp-of-approval audit.
we write contracts that hold the money our trading stacks move.
most "web3 dev shops" are body-shops with a logo. we're the team you call when the system has to actually work, in production, with real capital behind it.
every line we write ships to your repo. no platform lock-in, no shared IP, no licensing-back. when the engagement ends, you don't lose a system — you own it.
you talk to the people writing the code. our team is four engineers with backgrounds in tradfi hft, l1 protocol work, and protocol-side mm desks. nobody is learning on your engagement.
every release lands behind a kill-switch. contracts ship with fuzz harnesses, not just unit tests. execution paths are measured in p99, not averages. boring, on purpose.
we operate strategies on the same stacks we build for you. if a feed handler skips a tick, it's our pnl too. there's no clean abstraction between us and the code that goes to prod.
a 30-minute call. you describe what you're trying to ship; we tell you honestly whether we're the right team and what a small first engagement looks like. no nda, no sales follow-ups, no "let's circle back."
