Generic

How to tailor your Blockchain Security Researcher CV in three steps
- Mark the must-haves. Read the posting and highlight the tools, skills, and responsibilities it repeats or labels “required”.
- Match them to your real experience. For each must-have, find the place in your history where you actually did it, and move that evidence to the top — using the posting’s wording where it is honest.
- Cut what doesn’t help. Shorten or remove bullets that don’t support this particular job. Two strong, relevant lines beat six generic ones.
That’s exactly what renewed.cv automates: it extracts the requirements, rewrites your real experience around them, fact-checks the result against your original, and shows you a before/after match score.
Common Blockchain Security Researcher resume mistakes
- Writing "blockchain" without naming the chains, languages, or protocols you actually used
- No links to code, deployments, or audits that a hiring team can verify

Recommended structure: Summary → Technical skills (chains, languages, tools) → Experience → Projects and audits (with links) → Education.
