Senior Blockchain Architect — Technical Feasibility Review

Overview: We are seeking a senior blockchain / solution architect to perform a time-boxed technical feasibility and architecture review of an existing concept. This engagement is review-only. There is no implementation, no coding, and no expectation of ongoing work. This is a short, high-leverage diligence exercise intended to validate system mechanics, identify constraints, and surface failure modes before any build decision is made. Scope of Work: • Review a highlevel system concept centered on ERC721–based ownership mechanics • Evaluate architectural feasibility, scalability, and edge cases • Assess system constraints, risks, and potential failure points • Provide written, structured feedback on: ~Technical soundness ~ Design risks ~ Assumptions that should be validated before build ~ Areas that are defensible vs. easily replicated This is not a request to design, improve, or implement a solution. Engagement Parameters: • Duration: Shortterm (less than one month) • Estimated time: 2–6 hours • Deliverable: Written technical review (bullet points or memo format) • No code access • No repository access • No frontend, UX, or marketplace discussion • NDA required prior to receiving details Required Background: • Seniorlevel experience in solution architecture or blockchain architecture • Direct familiarity with ERC721 and tokenized ownership models • Experience reviewing or validating systems prior to build • Comfort identifying weaknesses and saying "this breaks" where applicable Explicitly Out of Scope: • Writing code • Building an MVP • Suggesting implementation services • Ongoing advisory or contracttohire discussions If you are primarily a builder or are looking for long-term development work, this role is not a fit.
