Daily ETH wallet monitoring with Etherscan, CoinGecko pricing & Discord alerts
Daily ETH Wallet Balance & Holdings Alerts
Never miss a snapshot of your (or others) ETH wallet, this workflow polls your wallet on a schedule, fetches balances and current ETH prices, formats a concise summary, and posts it to Discord (or email/Slack/Telegram). Easy to customize to track multiple wallets, tokens, or alert on thresholds.
How it works
- Schedule Trigger - Runs on your cadence (default: morning and evening).
- Query Blockchain - Calls Etherscan (or another API) to get wallet balances and token holdings.
- Process Balances - Calculates totals and converts values using CoinGecko price lookups.
- Format Summary - Creates a readable report (holdings, USD value, % change, etc.).
- Deliver Alert - Sends the snapshot to Discord (swap in Slack/Telegram/email/webhook as needed).
Quick setup notes
- Add your Etherscan (or preferred) API key and CoinGecko key where indicated.
- Set the wallet address(es) in the code node(s) supports one or many.
- Adjust the schedule, number of snapshots, and message format to suit your needs.
Use cases / variations
- Single-wallet daily snapshot - Quick morning/evening balances.
- Multi-wallet portfolio digest - Aggregate several addresses into one report.
- Token breakdown - Show ERC-20 token amounts and fiat values.
- Price/threshold alerts - Ping when ETH or a token crosses a set price or % change.
- On-demand reporting - Trigger via webhook or command to pull a live snapshot.
- NFT & token inventory - Report owned collections and token counts.
- Tax / bookkeeping exports - Add CSV output for record-keeping.
Why use this
- Hands-off monitoring - automated snapshots replace manual checks.
- Customizable - swap APIs, add wallets, or change channels in minutes.
- Actionable - get the data you need (holdings, fiat value, alerts) where you already work.
Daily Wallet Monitoring with Etherscan, CoinGecko Pricing & Discord Alerts
This n8n workflow provides a robust solution for daily monitoring of cryptocurrency wallet balances and their fiat value, delivering timely alerts to a Discord channel. It integrates with Etherscan to fetch Ethereum wallet balances and CoinGecko for current cryptocurrency prices, then calculates the total fiat value and sends a formatted message to Discord.
What it does
- Triggers Daily: The workflow is scheduled to run once every day.
- Fetches Wallet Balance: Makes an HTTP request to the Etherscan API to retrieve the ETH balance for a specified wallet address.
- Fetches Current Price: Makes an HTTP request to the CoinGecko API to get the current price of Ethereum in USD.
- Calculates Total Value: Uses a Code node to process the fetched balance and price, calculating the total USD value of the wallet.
- Sends Discord Alert: Formats a message with the wallet address, current ETH balance, and its USD value, then posts it to a designated Discord channel.
Prerequisites/Requirements
- n8n Instance: A running n8n instance.
- Etherscan API Key: An API key from Etherscan (for fetching wallet balances).
- CoinGecko API: No API key is typically required for basic price lookups.
- Discord Webhook URL: A Discord webhook URL for the channel where alerts should be posted.
- Ethereum Wallet Address: The ETH wallet address you wish to monitor.
Setup/Usage
- Import the Workflow: Import the provided JSON into your n8n instance.
- Configure Credentials:
- HTTP Request (Etherscan):
- Edit the "HTTP Request" node connected to Etherscan.
- Update the URL to include your Etherscan API key and the Ethereum wallet address you want to monitor.
- Example URL structure:
https://api.etherscan.io/api?module=account&action=balance&address={{$json.walletAddress}}&tag=latest&apikey={{$env.ETHERSCAN_API_KEY}}(you might need to replace{{$json.walletAddress}}and{{$env.ETHERSCAN_API_KEY}}with direct values or expressions if not using environment variables/previous nodes to set them).
- Discord:
- Edit the "Discord" node.
- Set the "Webhook URL" to your Discord channel's webhook URL.
- HTTP Request (Etherscan):
- Configure Schedule: The "Schedule Trigger" node is set to run daily. You can adjust the schedule as needed (e.g., specific time, different interval).
- Activate the Workflow: Save and activate the workflow. It will now run on its defined schedule, sending daily updates to your Discord channel.

AI-powered code review with linting, red-marked corrections in Google Sheets & Slack
Advanced Code Review Automation (AI + Lint + Slack) Who’s it for For software engineers, QA teams, and tech leads who want to automate intelligent code reviews with both AI-driven suggestions and rule-based linting — all managed in Google Sheets with instant Slack summaries. How it works This workflow performs a two-layer review system: Lint Check: Runs a lightweight static analysis to find common issues (e.g., use of var, console.log, unbalanced braces). AI Review: Sends valid code to Gemini AI, which provides human-like review feedback with severity classification (Critical, Major, Minor) and visual highlights (red/orange tags). Formatter: Combines lint and AI results, calculating an overall score (0–10). Aggregator: Summarizes results for quick comparison. Google Sheets Writer: Appends results to your review log. Slack Notification: Posts a concise summary (e.g., number of issues and average score) to your team’s channel. How to set up Connect Google Sheets and Slack credentials in n8n. Replace placeholders (<YOURSPREADSHEETID>, <YOURSHEETGIDORNAME>, <YOURSLACKCHANNEL_ID>). Adjust the AI review prompt or lint rules as needed. Activate the workflow — reviews will start automatically whenever new code is added to the sheet. Requirements Google Sheets and Slack integrations enabled A configured AI node (Gemini, OpenAI, or compatible) Proper permissions to write to your target Google Sheet How to customize Add more linting rules (naming conventions, spacing, forbidden APIs) Extend the AI prompt for project-specific guidelines Customize the Slack message formatting Export analytics to a dashboard (e.g., Notion or Data Studio) Why it’s valuable This workflow brings realistic, team-oriented AI-assisted code review to n8n — combining the speed of automated linting with the nuance of human-style feedback. It saves time, improves code quality, and keeps your team’s review history transparent and centralized.
By higashiyama Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review
This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
