Tutorials
Step-by-step guides for integrating EthIntel into your applications.
Developer Tutorials
End-to-end integration guides with working code
Longer than API reference snippets on purpose. Each tutorial shows how EthIntel endpoints fit into real workflows — alerting, pre-sign review, portfolio UX, and extensions.
Build a Transaction Alert Bot in 30 Minutes
Node.js + fetch: poll addresses for new transactions and send Telegram/Discord notifications with explanations.
Add Safety Scanning to Your DApp's Sign Flow
React pre-sign review: call POST /api/scan before wallet signature and display risk score + signals in a modal.
Build a Portfolio Transaction History Page
Next.js App Router page: fetch address profile + recent transactions with pagination and inline AI explanations.
Embed Transaction Intelligence in Your Wallet Extension
Chrome MV3 extension: inject explanation cards on block explorer pages with caching and safety banners.
How to use these guides
Each tutorial is a copy-paste-first build guide. Start with the raw Markdown, keep the API reference open in another tab, and replace demo transaction sources with your own product logic once the EthIntel calls are working.
