// SKILLS

Our toolkit, scattered across the bench

Grab one. Throw it. The stack we reach for across blockchain, Web3, and AI.

// DEVELOPMENT CYCLE

How a system gets built here

Six phases, each a block in the chain. Open one to see what happens inside it.

We scope the work, map constraints, and surface the riskiest unknowns first — before a line of code is written.

// CASE STUDIES

A few we can talk about

Challenge, what we built, and the numbers that came out the other side.

IDDAS

IDDAS — proving physical ads actually happened

Challenge. Offline advertising is opaque: sponsors pay for estimated impressions with no way to prove real people interacted or that revenue was split fairly.

Solution. IDDAS — a blockchain-anchored verification layer: a hash-chained ledger, Merkle sealing, and a deterministic pricing & scoring engine, with roots committed to Polygon.

Result. Every interaction is provable, every calculation reproducible, and every allocation auditable — with no trust required in the operator.

CandleMe

CandleMe — from a QR scan to a living candle in one redirect

Challenge. Every extra onboarding screen loses 20–40% of users — a five-step registration flow can shed over 90% of the people who scanned a physical QR code.

Solution. A dual-product activation platform: frictionless progressive identity, QR/link activation with structural referral trees, and a consumer PWA whose flame is a GLSL shader driven by real device sensors.

Result. Anonymous users get a working, fully attributed experience the instant they scan — while distributors keep hierarchical roles, audit trails, and usage-metered billing.

What clients say when the dust settles

“They took a rough brief and turned it into a platform our whole organisation runs on. Delivered on time, every time — that is rarer than it should be.”

“Payments leave no room for mistakes. The team built Maninipay with the rigor of people who understood exactly what was at stake for our customers.”

“They cut our on-chain settlement costs by 75% without touching our existing contracts. That is the kind of engineering you rarely find.”

GMGeorge MuellerFounder, Northbound

“Leo went from an idea to a live product with paying subscribers. AI pipeline, payments, polish — they handled all of it, and it shows.”

// ABOUT US

DevXe Labs exists to make decentralized and intelligent systems boring to build — reliable, audited, and shipped on schedule.

We started as a handful of protocol and ML engineers who were tired of watching good ideas die in audit. So we built a studio around the unglamorous parts — the testing, the threat modeling, the monitoring — and made them the point. Today we partner with teams shipping on-chain infrastructure and AI systems that have to work the first time.

Security-first

Threat models before features. We assume the adversary is smarter.

AI-augmented engineering

We use the tools we build with — and ship faster for it.

Senior team, no bench

The people who pitch are the people who build. No hand-offs.

Ship in the open

Audited, documented, and handed over — never a black box.
