Meme Coin Radar

Problem

New meme coins appear faster than any human can watch. I wanted a machine that watches DEXScreener and Pump.fun around the clock and only pings me when something scores well.

Constraints

• Must run unattended without babysitting
• Alert noise must stay low — every alert costs attention
• No real-money trading until alerts prove accurate over time

Approach

1. Poll DEXScreener and Pump.fun on a fixed schedule
2. Score each new coin on liquidity, velocity, and holder signals
3. Send Telegram alerts only above threshold, with a daily accuracy report grading every alert

Key decisions

• Alerts as implicit 24h up-predictions, graded daily

  Forces honesty — every ping is scored instead of forgotten.

• Read-only trading stance until accuracy clears 90%

  No wallet keys on the machine, no real trades before evidence.

What failed first

Early scoring was too trigger-happy — too many alerts, most went nowhere. Tightening thresholds and adding the daily grading loop cut noise instead of adding more signals.

Result

Runs continuously with a daily accuracy report. Trading stays read-only until the alerts prove themselves.

Lessons

• An alert system without grading is just spam with extra steps.
• Reliability (scheduler, deduplication, cost) matters more than clever scoring.
