Market manipulation patterns on pump.fun

Updated 23 Oct 2026 17:48 UTC. Wallet clustering, pump-and-dump patterns, caller behavior and exchange cash-out paths, from public on-chain data. Methodology & disputes · API: /v1/forensics/trace/<wallet>, /v1/forensics/token/<mint>, /v1/forensics/kol/<wallet|handle> (MCP: trace_wallet, token_manipulation_score, kol_scorecard).

New: Contest watch, independent integrity monitoring of the pump.fun Squads Invitational (anomaly indicators and evidence packs).

Case files

279 evidence packs built 2026-10-23 18:31:52 UTC: 209 token, 30 cluster, 40 kol. Each pack lists every supporting transaction (Solscan links, UTC block time, amounts), the funding and exchange cash-out graph with label sources, a timeline of launch, early buys, calls and sells with price impact, per-wallet P&L, detector results with confidence and false-positive notes, and a SHA-256 hash of the pack. Detectors fired: creator sell-off 208, caller sold into call 166, bundled launch 153, recurring launch-and-exit 30, sells after call 11. Public pages are previews; the full JSON, printable HTML and PDF are in the API (/v1/forensics/case/<id>) and MCP tool forensics_case.

Where the money went

Outbound SOL/USDC from creator wallets, followed up to 3 hops, until it reached a hot wallet labeled as a centralized exchange. Amounts are upper bounds of the traced wallet's funds on each path (the smallest transfer along the path). An intermediate address that forwards to an exchange hot wallet is likely an exchange deposit address, which exchanges can map to an account on request from law enforcement or a brand's counsel.

Repeat launcher groups

Creator wallets grouped by shared funding wallets, shared exchange deposit paths and repeat creation-block buyers, with 5+ launches in 7 days (3+ analyzed). "Serial pattern" = 80%+ of analyzed launches died (below 30% of peak and no trades for 2 h), consistent with serial pump-and-dump launches.

Caller scorecards

Public pump.fun callouts by accounts with 1,000+ followers, joined with the caller wallet's own on-chain trades. Ranked on calls of tokens the caller did not create. "Bought before call" = the caller wallet bought the token before posting it; "Sold within 1 h" = of those, the share it sold within an hour after the call. Creator→caller transfers are only counted when found in a traced creator wallet.

Automated on-chain pattern analysis of public blockchain data. Labels describe transaction patterns "consistent with" known manipulation techniques; they are not findings of wrongdoing by any person, and wallets are not linked to real identities. Exchange labels come from public community datasets and can be incomplete or wrong. Not investment, financial or legal advice.
