How PumpStriker works: from wallet buys to a graded signal

The Engine reads GMGN's smart-money trade feed every 10 seconds and its KOL trade feed every 15 seconds. It also scans GMGN's new, near-graduation and graduated token lists every 30 to 180 seconds and reads GMGN token signals every 45 to 180 seconds; both scans pause at the leanest budget level. Token signals are recorded as extra facts and never fire a signal by themselves.

Only tokens from Pump.fun (including PumpSwap and Mayhem launches), Bags, LetsBonk and Jupiter Studio are considered. A token out of scope, or whose age is known to be more than one day, is dropped for good. For a migrated token the age counts from its pool, so an older token on a new pool can still qualify.

Distinct buyers of one token are counted inside a trailing 30-minute window. One buyer is noted, two trigger a first token check, and three trigger a full check. Tokens with three buyers that are just short of the bar get their data refreshed more often, every 30, 60 or 180 seconds, and a new buy pulls the next read forward.

Fresh price. Before deciding, the Engine takes a fresh snapshot: the pool, the last hour of 1-minute candles, security data if needed, and a quote. It decides only on a quote at most 30 seconds old, for a token that traded in the last 10 minutes and whose price is not frozen. If it cannot get one, it retries for up to 3 minutes and then records the token as unpriceable.

Safety kills. Eleven hard rules (K1 to K12; there is no K7) remove tokens that GMGN's data flags as honeypots or unsellable, or with a blacklist function, live mint or freeze authority, a sell tax of 10% or more, a Mayhem launch, a dev wallet over 25%, top-10 holders at 50% or more, wash trading or a market cap under $5,000. A killed token is recorded and never sent.

Unknown is not safe. An unknown value never kills. If mint authority, freeze authority, sell tax or the top-10 share is unknown, the signal is marked safety pending, which closes every auto-buy tier (grade C). Other unknown checks (honeypot, cannot-sell, blacklist, dev wallet, wash trading, Mayhem) are recorded as data gaps, do not change the grade, and are re-checked for 5 minutes after the signal.

Labels. Every decision also gets named true, false or unknown labels: acting labels used by the auto-buy tiers, measured labels that are recorded only, and quality labels for data problems. Beyond the hard kills and the safety tiers, every decision records more than 30 named risk and data-quality labels, such as insider and bundler share, copycat names and late clusters. They are kept for transparency and auditing and do not change the decision.

• Grade A: passed B2, so every tier, with a market cap from $10,000 to under $25,000.
• Grade B: passed B1 but not B2.
• Grade C: everything else, including safety pending. Not shown in Telegram at the default setting.

A grade is a sorting label. It is not a forecast and not a ranking of how a token might trade.

By default only grade B or better is marked for Telegram, and never a token under 60 minutes old that already trades 3x or more above its launch price. The bot then applies your own filters: Signals Active, Min Score, the market-cap and liquidity bands and the lowest card grade.

The signal goes to your own bot through a local, authenticated outbox that retries for up to 10 minutes. A signal that cannot be delivered in that time is recorded as expired: it is never shown late or bought, and none is sent twice.

The card shows the grade, the score, the entry price, market data, the safety status, smart-money and KOL counts, the reasons, the exit plan and buy buttons. At most 8 signal cards go out per 10 minutes; the rest wait and none are dropped, while cancels and alerts are not paced. Signal cards arrive around the clock while your machine runs; the optional session window limits only auto-buy, and exits always run.

Because the decision is frozen with its inputs and their ages, you can always see what the Engine knew at that moment and how old each value was. Selected examples from PumpStriker's signal records, each with its detection time, are on the Hall of Fame page.

• Second look. For 5 minutes after a signal, safety facts that were unknown keep being re-checked. If one now fails, one cancel goes out and a position that auto-buy opened is sold. Your own buys, including Buy taps on a signal card, are never touched.
• Tracking. Grade A and B signals are tracked live for up to 6 hours. Exit alerts follow the default plan and never sell by themselves.
• The record. Each decision is re-read about 6 and 24 hours later (grade A and B signals also after about 1 hour) so the rules stay auditable. Every signal stays on the record, and the dashboard lists every signal with CSV download.

• A signal or a grade is information, not a forecast, and no tool can make an outcome certain.
• The trigger is built on public GMGN data that other GMGN users can also see.
• Data can be missing, late or wrong, and a token can change faster than any check.
• The checks rely on third-party data and services: GMGN, Solana RPC providers and Jupiter.
• What your Engine sees depends on its GMGN key, its budget level and your settings.
• Nothing runs while your machine is off.
