Tadeas Vrábel Lead dApp Architect
Spent several years building EVM-compatible protocols before moving into consulting. Tends to ask uncomfortable questions about token economics early in a project.
dApp consulting
without the noise
Building on-chain requires more than code — it requires someone who has already made the expensive mistakes and knows which ones to skip.
Moxelwyn Ist works with founders, developers, and organizations navigating decentralized architecture from first contract to production deployment.
Operating since 2020
Remote-first by design. Clients across twelve countries have used Moxelwyn Ist to structure their dApp projects, audit their contract logic, and choose the right chain for their use case.
What the team actually does
Moxelwyn Ist handles the full technical surface of decentralized application work — from architecture decisions early in a project to contract review before a mainnet launch.
Clients tend to arrive with one of three problems: a contract that behaves unexpectedly on testnet, a wallet integration that breaks on mobile, or a protocol choice that made sense six months ago but no longer fits their product. Each situation gets treated separately.
Focus to read — working approach
Sessions run asynchronously or in real time depending on what the client needs. Most technical reviews happen over shared documents and screen recordings before any live call. This keeps the conversation focused and skips the part where everyone restates the problem for twenty minutes.

People behind the work
Orsolya Fekete Protocol Integration Specialist
Focuses on the gap between smart contract logic and the interfaces that users actually touch. Has strong opinions about when not to use a particular chain.
Rúairí Ó Briain Security Review Consultant
Brought in specifically for pre-launch contract reviews. Works independently and delivers written reports rather than verbal summaries — findings are easier to act on that way.
