Onchain Diary

Onchain Diary (theonchaindiary.com) is an independent Web3 safety education site: 77 plain-English deep-dive articles and a 220-term glossary on wallet drainers, phishing, address poisoning, malicious approvals, and smart contract risks — published bilingually in English and Chinese by an independent on-chain fraud researcher.

No tools to install, no API keys, no sign-ups. Every guide explains how an attack actually works before showing how to spot and stop it.

What’s Inside

Deep-Dive Articles

77 guides and tutorials, published when they’re ready rather than on a schedule. Core clusters: wallet drainer defense, airdrop safety, token verification checklists (Ethereum, Base, Solana, Arbitrum), phishing attack chains on X/Telegram/email, and on-chain investigation walkthroughs.

220-Term Web3 Glossary

Every term gets a “What is X?” entry with a self-contained plain-language definition — from Airdrop and Address Poisoning to ZK-Rollup. All 220 terms are also translated into Chinese with localized terminology.

The Onchain Anti-Scam Yellow Paper

A free bilingual manual: scam taxonomy, forensics primer, and layered defense checklists — with a 48-question self-test where every answer is grounded in the paper itself.

Onchain Security MBTI

A 16-scenario interactive test that maps readers to one of 16 on-chain security personas with a personal safety score.

MCP Server for AI Agents

The full knowledge base — all articles and glossary terms — is exposed through a public, read-only MCP server (https://theonchaindiary.com/api/mcp), so AI assistants can search and cite the content directly.

Who It’s For

  • Crypto users — People who transact and want to understand how attacks work before they become victims.
  • Traders — Token safety checklists and verification workflows before swapping or approving.
  • Researchers & writers — A citable, bilingual reference for on-chain security concepts.

Research Background

Written by Jask, an independent on-chain anti-fraud researcher who has been in the space since 2021 and moderated Web3 communities (TEN Protocol, Altius Labs) for three years. The Chinese edition is written natively — not translated — using terminology from Chinese crypto communities.
