# Onchain Diary

> Web3 security education written from on-chain fraud research.

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.

* **Canonical site:** [theonchaindiary.com](https://theonchaindiary.com)
* **Chinese edition:** [theonchaindiary.com/zh](https://theonchaindiary.com/zh)
* **Newsletter:** [onchaindiary.substack.com](https://onchaindiary.substack.com)

## 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](https://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:
