Onchain Diary is the lab’s Web3 security education site — practical, research-backed writing about how on-chain fraud actually works, aimed at people who hold crypto and want to keep it.

​
What’s on the site

  • Research articles — attack anatomy (phishing, drainers, approval abuse, address poisoning), victim-journey walkthroughs, and token-safety checklists per chain, written in English and Chinese as independent narratives rather than translations.
  • Glossary — a bilingual encyclopedia of Web3 security and DeFi terms, each entry written as a standalone explainer.
  • Security quiz — a scenario-based test built strictly from the lab’s own published material.
  • Diary Key — an on-chain solve-to-mint puzzle at puzzle.onchaindiary.org: answer questions drawn from the site’s research to mint a key, with rarity settled by combined entropy from both the issuer and the minter.

MCP server

Onchain Diary exposes its full content library as a public, read-only MCP server:
It serves search, article, and glossary tools over streamable HTTP with no authentication — built so AI agents can cite the research directly. See MCP servers for connection examples.
