Summary

On 28 of 53 calls of tokens it did not create, wallet 4JXU…nPaL bought before posting (median 0.7 min before) and sold 50%+ within 30 minutes after (median 3.2 min after the call) while other wallets were buying (1429.92 SOL from 3406 buys-by-wallet between the calls and the sells); net +2.204 SOL on those calls. pump.fun callouts are tied to a position, so holding before the call is expected; the flagged part is selling into post-call buying.
24 of 53 called tokens fell 50%+ below the call-time market cap within 1 h. This is a market outcome, not evidence of the caller's own selling; shown as context and not counted as a detector.

Detectors

Each detector reports on-chain facts only, with a confidence from 0 to 1 that the pattern is present (not a finding about intent or identity).

Caller bought before its calls and sold into them fired · confidence 0.78 (high)
On 28 of 53 calls of tokens it did not create, wallet 4JXU…nPaL bought before posting (median 0.7 min before) and sold 50%+ within 30 minutes after (median 3.2 min after the call) while other wallets were buying (1429.92 SOL from 3406 buys-by-wallet between the calls and the sells); net +2.204 SOL on those calls. pump.fun callouts are tied to a position, so holding before the call is expected; the flagged part is selling into post-call buying.
False-positive risk: A caller can buy because they like the token and post it later; selling after posting can be ordinary profit-taking. We report timing only.

Called tokens fell 50%+ within 1 h (context, not a detector) not fired
24 of 53 called tokens fell 50%+ below the call-time market cap within 1 h. This is a market outcome, not evidence of the caller's own selling; shown as context and not counted as a detector.
False-positive risk: Many traders react to the same call; wallets of a group selling at once can also be one bot managing several wallets for unrelated reasons.

Limitations

Bonding-curve trades on pump.fun only (decoded from public Solana data by our collector); trades after migration to a DEX and transfers outside the curve are not in P&L.
P&L is in SOL, before fees and priority tips; unrealized value uses the last bonding-curve price, which a large sale could not achieve.
Wallet links are statistical (shared creation-block buying, shared funding wallet, shared exchange deposit path); one person can use many wallets and unrelated people can share infrastructure such as bots.
Caller (KOL) call times are pump.fun home-feed callout times; we link the caller's public X profile and, where we captured it, the post. Telegram calls are not collected.
Exchange cash-out paths follow up to 3 hops of plain SOL/USDC transfers and stop at labeled exchange wallets; amounts are upper bounds of the traced wallet's money on that path.
Collector gaps (RPC drops) can miss a small share of trades; transaction signatures can be checked independently on Solscan or any Solana node.

Automated analysis of public blockchain data. Detectors report on-chain facts and patterns "consistent with" known manipulation techniques; they make no claim about the intent or identity of any person. Wallets are not linked to real identities. Exchange labels come from public datasets and can be wrong. Not legal, financial or investment advice. Corrections: admin@deepcounterfeit.com.
