AI and blockchain systems.
Tools. Demos.
Production systems, delivered: AI integrations, smart contracts, and the Go backends underneath. Every contract is lint-gated, statically analyzed, invariant-fuzzed by two engines, coverage-gated and deployed live on Base Sepolia — drive the demos yourself.
Founders describe a business idea and get a structured, AI-driven viability analysis — market demand, competition, risks — in 10 languages.

Every demo here runs on real AI — nothing mocked. In three, the model's ruling lands on Base Sepolia, verbatim and permanent.
In the escrow, a seller releases funds with a Groth16 proof of a delivery secret — the secret is never revealed, not even to the contract. When delivery is contested, the case goes to an AI arbiter: it reads the evidence both parties published on-chain, rules, and its full reasoning is written back to the chain verbatim, permanently.
The arbiter's power is bounded by the bytecode. It can credit a pull-payment balance and nothing else — it cannot push funds, cannot touch an escrow that isn't disputed, and cannot revisit one that's settled. That's the part worth looking at: not that an AI made a decision, but that the decision is auditable and the authority is enforced by a contract rather than a policy.
No screenshots, no mock data. Contract addresses are on BaseScan, source is on GitHub, and every settlement is sitting there to read.

Go & systems labs
Runnable labs for the awkward parts of systems work — backpressure, profiling, reconciliation, scheduling, and the Rust ownership rules that trip everyone up. Each one is driven in the browser and computed from real code.

Rust Move Lab
Who owns this value? Ask rustc, then watch the Go program run.
-
Rust Borrow Lab
Two refusals, and the program the borrow checker accepts.
-
Rust Send/Sync Lab
A guarantee on one side, a detector that watches on the other.
-
ETL Lab
State that is never kept is state that cannot go stale.
Practical tools
Free online tools built and run in-house — from OSINT and security checks to SEO and marketing analyzers.
-
TraceCheck
Trace an email header end to end and see every hop it really took.
-
Domain Recon
Pull DNS, WHOIS, and mail records for any domain in one pass.
-
EXIF Metadata
Reveal the camera, location, and edit history hidden inside an image.
-
Fake Recruiter Check
Test whether a recruiter message is a real opening or a scam.
Not another AI wrapper.
Every tool here hits real infrastructure — DNS, WHOIS, TLS, raw metadata — before any model reasons over it. Evidence first, interpretation second, and you can verify every signal yourself. Same rule on-chain: the arbiter's authority is whatever the contract grants it, and its reasoning is public record.
What Pigfox delivers
Engagements start with an outcome rather than a stack: an AI integration that earns its place, a smart contract you can audit before you trust it, or the Go backend underneath them. Pigfox designs it, builds it, ships it to production, and stays on it afterwards.
Go/Golang
The APIs, proxies, and backend systems underneath — built to run in production for years, and handed over documented.
AI engineering
AI features that earn their place, on real infrastructure — and AI-augmented delivery to get there sooner.
Organic SEO
Technical search optimization that compounds instead of expiring — the same work that ranks this site.
- AI engineering & AI-augmented development
- Smart contracts, tested and fuzzed before they ship
- Go/Golang APIs & backend systems
- APIs & Proxies
- Web sites & applications
- Rebuilding or upgrading outdated business systems
- WASM applications
- Organic Search Engine Optimization
- Practical tools — OSINT and security checks, SEO and marketing analyzers
Build something together
If you have a system to build — an AI integration, a contract that has to be trustworthy, a backend that has to hold up — get in touch and describe it. You will get a straight answer on whether Pigfox is the right fit, what the work involves, and what it would take to ship it. Partnerships and ventures are welcome on the same terms.
