Telegram Ethereum Insider Buy Alert

Overview

Flags wallets on Ethereum that buy tokens before public announcements.

Dependencies

from lib.gumloop_telegram import BotConfig, send_alert, build_alert, ScheduledBot, escape_md
import requests, os, json

Bot Config

config = BotConfig(bot_token=os.environ["TELEGRAM_BOT_TOKEN"], chat_id=os.environ["TELEGRAM_CHAT_ID"])
EXPLORER = "https://etherscan.io"

Insider Detection

def early_buyers(tok, block):
    url = f"{EXPLORER}/api?module=account&action=tokentx&contractaddress={tok}&startblock={block}&endblock={block+100}&sort=asc"
    buyers = {}
    for tx in requests.get(url, timeout=15).json().get("result", []):
        addr = tx["to"].lower()
        val = float(tx.get("value", 0)) / 10**int(tx.get("tokenDecimal", 18))
        buyers[addr] = buyers.get(addr, 0) + val
    return buyers

Webhook Mode

from flask import Flask, request
app = Flask(__name__)
@app.route("/webhook/insider-check", methods=["POST"])
def check():
    data = request.json
    buyers = early_buyers(data["token"], data.get("deployBlock", 0))
    for addr, amt in sorted(buyers.items(), key=lambda x: -x[1])[:5]:
        send_alert(config, f"👀 *Insider Buy*\nToken: {data['token'][:8]}...\nWallet: `{addr[:6]}...`\nAmount: {amt:,.2f}")
    return "ok", 200

Docker

FROM python:3.11-slim
WORKDIR /app
RUN pip install lib-gumloop-telegram requests flask
COPY bot.py .
CMD ["python", "bot.py"]

docker build -t tg-eth-insider .
docker run -d -e TELEGRAM_BOT_TOKEN=x -e TELEGRAM_CHAT_ID=y tg-eth-insider

Risk Filters

• Flag wallets appearing in 3+ token launches as early buyer
• Check if buyer was funded by CEX before purchase
• Multi-wallet buys from same funder = coordinated insider
