# @fomosaurus wallet hunt, 7 Sep 2026

- [stated] Ben asked to find fomosaurus's wallets, not via fomo, using the coins and dates in his posts: "he talks about buying PARE between 20-40k market cap and has many coins that aren't that popular. check the dates and coins and find his wallets"

## The dated statements that did the work (all from twitterapi.io, from:fomosaurus, 500 posts back to Dec 2024)
- PARE (0x15d36B6A28d8327ABc7aFABF0F106AE2c9Af5C4d, pair created 2 Sep 23:35 UTC): 6 Sep 08:16 "We made our first buys in the $20K–$40K market cap range and remain bullish"; 3 Sep 11:47 in the PARE thread "I paperhanded this at around 25-40K MC initially and had to buy back substantially higher"
- RSRV (0x942E390b0D316C897336620da42a2F2a340F93EC, The Reserve, pair created 5 Sep 18:31 UTC): 6 Sep 15:02 "Nope, I bought it at 250k and higher"
- ZZZ (0x7dbf38976f6d3b9c529e7d9484a71898b409ee6a, the xdev_10 AI coin, pair 4 Sep 23:55): 5 Sep 13:39 "RH may be primed for some AI bellwethers... xdev_10"
- UBIK (0x812486EAea648819853F8E372dc9f1516C7868Bd): 5 Sep 15:17 "$UBIK too", replying to a ZZZ post
- CASHCAT: 5 Aug 23:02 thanked the Hyperliquid whale that "cleared the books", so he held it then
- Sep 4 06:53 "bought 4 other things in that 2 hour stretch that were all losses"
- STONKBROKER: "Fully exited at 10M" (2 Aug) is the SOLANA one, no EVM trail. "caught it at 800,000 market cap" (26 Jul) is about PEPE, not a Robinhood coin, do not reuse it

## THE WALLET: 0x643798a32806d6571daf5b664012409aeba11e0e
- EIP-7702 wallet (code 0xef0100e6ca), every counterparty is the fomo/Relay settlement contract 0xb92fe925dc43a0ecde6c8b1a2709c170ec4fff4f, so it is a fomo-rail account. First activity 22 Jul 2026, 631 token legs, 157 tokens. Same address exists on Ethereum (nonce 1), Base (2), BNB (2), nothing there
- It is the ONLY wallet in the four-way intersection: bought PARE under $45k mcap (374 wallets) AND held UBIK at 5 Sep 15:17 (1,580) AND held ZZZ at 5 Sep 13:39 (7,317) AND first RSRV buy at or above $200k mcap (1,236). One address survives all four
- PARE ledger matches the words exactly: bought 4,659,700 in four clips 2 Sep 23:41-23:55 at $36k-$76k mcap, sold ALL of it 3 Sep 00:07 inside the crash candle (open $31.7k, low $13.3k), then bought back 7.9M from 03:09 at $497k-$1.2M. That is "paperhanded at 25-40K and had to buy back substantially higher", verbatim. It then scalped PARE in and out through 3-4 Sep and was flat by 4 Sep 05:29; on 7 Sep morning it holds 251,348 PARE again
- RSRV: ten buys 6 Sep 11:08-12:57 at $208k-$584k mcap (1B supply basis), held 9,791,544 at 05:00 UTC 7 Sep, then sold down to 4,785,870 by 05:45 UTC 7 Sep. "Bought it at 250k and higher"
- ZZZ bought 5 Sep 02:00, eleven hours before the AI bellwether post; holds 224,293
- UBIK held 199,039 at the time of "$UBIK too"; 39,763 now
- CASHCAT: held 12,899 from 25 Jul until roughly 24 Aug, so it was held on 5 Aug. Tiny, about $1.4k
- 3-4 Sep 23:08-01:06 it bought TAM, LEGS, IMG, MM and TTWO in two hours and dumped four of them, which fits "bought 4 other things in that 2 hour stretch that were all losses"
- It receives the same planted-token spam that unipcs receives (HAKU, PREPLY, QUIL, MORPH, PAYLESS, TAMPONS, ODD, HTB, CLUBY, UPS, WEREY, all 1 in 0 out on 6 Sep). Planters only target wallets that show on people's feeds, so this is a followed fomo account, not a random retail wallet

## What is NOT proven, say it plainly
- No fomo handle. fomo.family/profile/fomosaurus is "User not found", and the wallet's RSRV position did not appear in fomo's named RSRV holder list (390 named of 1K), so the fomo handle is something else or the profile is not indexed. The identification is behavioural (five dated statements, unique intersection), not a self-disclosure
- He wrote "we" and "remain bullish" on PARE on 6 Sep while this wallet was flat on PARE. Either "we" includes a second wallet, or he talks his book while out. No second wallet fitting PARE-early plus RSRV exists on chain: PARE early buyers still holding (0x4f61815d66ac5dd30f8fef0d642e3946650f8213, 0xc0fd8bb21f2c58a1788105ba40a7365ff6fa76b2, 0x9f7251c4a8645e838955767319427443d30a1b5c) hold zero RSRV
- The wallet is small and fast: $100s to low $1,000s per clip, in and out within hours. His public voice is a long-form thesis writer; his chain behaviour is a scalper. Both can be true of one person, but a copy tracker on this wallet will fire many small flips

## Identity wallet, confirmed his but dormant: fomosaurus.eth = 0x724ce2221206521bd8fd1f5950061a783e4eea0e
- ENS registered 18 Jun 2020 ("Farmer class of 2020"), 141 mainnet txs, 0.0107 ETH left, nonce 0 on Robinhood Chain, Base, Arbitrum, BNB, Optimism. Held 2020-era DeFi bags (FET, SNX, LPT, REN, KNCL, TRAC) and he posted 15 Oct 2025 "I remember buying this [TRAC] with my keystore wallet file", which this wallet did in 2020
- Cleaned out on 11 Dec 2025 (the day of his $NIGHT/$WET post): sold FET, SNX, LPT through the MetaMask swap router and sent 1.1 ETH to 0xafcaea0dd931a3272b89d2113808cdaa2f0f64e4
- 0xafcaea0dd931a3272b89d2113808cdaa2f0f64e4 is a forwarding address that sweeps into 0x7dbb4bdcfe614398d1a68ecc219f15280d0959e0 (440 ETH, nonce 9,837, address-poisoned, an exchange hot wallet). It receives from 18+ unrelated wallets, so it is NOT a per-user deposit address and its other senders are NOT his. Dead end, recorded so it is not re-chased. Two of those senders (0x1b5b7b514771beec3c83add7e0165166dbc77320, 0x064271ee567925f7fa90188ce1c3040d74eb72c5) are RH-active but 0x1b5b7b51 bought PARE at $5.9M, which rules it out on his own words

## Method notes, reusable
- The whole hunt was: pull the timeline, take every post that names a coin with a date and a price level, translate each into a block-bounded holder set from eth_getLogs, intersect. Four sets collapsed 9,000 PARE wallets to one address in one pass. Same method as [[uberm-wallets]]; it works because he states entries in market-cap terms
- Mcap-at-block: GeckoTerminal minute candles for the first pool, block to time via a linear fit between two anchors (RH chain runs 9.93 blocks/s), candle close times supply. Good to the minute, which is what "paperhanded at 25-40K" needs
- The v4 PoolManager 0x8366a39cc670b4001a1121b8f6a443a643e40951, routers 0x8f10b468b06c6fd214b65f87778827f7d113f996, 0x039ec98a76f111092d4751365ff09dd2aec301e8, 0x39b38686a19836ac10162c490e4558e120cbbe5f, 0x1d4b86491ec211257cbedd77a4380a7494624eff, the fomo relay 0xb92fe925dc43a0ecde6c8b1a2709c170ec4fff4f and executor 0xccc88a9d1b4ed6b0eaba998850414b24f1c315be must be excluded from any holder set or they top every list
- 0x267444d099b10fb5ed7c3cc7b7c767adca574952 is a 1,970-byte contract holding exactly 81,632,653 of PARE, UBIK and RSRV each: a launchpad allocation vault, appears in every early-buyer screen, never a person
- High-volume tokens (UBIK, ZZZ) time out eth_getLogs at 10k blocks near launch. Use the adaptive bisecting puller (/tmp/fs/pull.py pattern: 20k chunks, halve on failure down to 500) in the background with nohup; UBIK took 300k legs, ZZZ 248k
- Blockscout txlist on eth.blockscout.com 429s after a few calls; space them 15s apart
- Planted-token spam landing in a wallet is a positive identity signal on this chain: it means the wallet is on someone's followed list. Use it as a tie-breaker between candidates

## 7 Sep 2026, second pass, Ben challenged the identification and it now stands at about 55%, not 70%

- [stated] Ben: "are we sure this is his wallet? He just bought $47 of QStrat and $41 of Fab... QStrat is at a $3 or $4 million market cap... Are these drops into his wallet?"
- THE $49 CLIPS ARE REAL BUYS, NOT DROPS. Verified with the v2 verifier logic: routed through the fomo executor 0xccc88a9d1b4ed6b0eaba998850414b24f1c315be, USDG paid, tx.value 0. Same hour (7 Sep 04:05 to 05:54 UTC) the wallet also sold about $12,000 of RSRV in $380 to $1,412 clips through the EntryPoint 0x4337084d9e255ff0702461cf8895ce9e3b5ff108, bought $5,468 of PARE in three clips, $1,491 ZZZ, $1,988 UBIK, round-tripped $2,005 OURO, then four $49 probes in seven minutes (FAB, PORT, QSTRAT, STRATTON). A mixed-size trader: $49 lottery tickets on top of $500 to $2,500 positions. His own 4 Sep words ("bought 4 other things in that 2 hour stretch") describe this exact habit. Note: on this wallet SELLS go through the EntryPoint as its own UserOps and BUYS arrive through the fomo executor
- **THE TEST IT FAILS: STONKBROKER.** He posted 2 Aug "Fully exited at 10M and feeling poor ever since". STONKBROKER (0xe934e36A439C94017B64a3FecE66AF12099aBF50, pair 18 Jul 03:50) crossed $10M on 29 Jul 08:00 and held $9M to $12M until 1 Aug 12:00, then ran to $39M by 11 Aug. 0x643798a32806d6571daf5b664012409aeba11e0e never touched STONKBROKER until a $1 basket buy on 27 Aug. It also holds NO RSRV Notes NFT (zero ERC-721 receipts since 5 Sep) despite his intimate Notes commentary
- THE JULY CLUSTER: 980 wallets bought STONKBROKER before 29 Jul 08:00, sold 97%+ with the last sell inside the $10M window and never rebought. 39 of those also held 100+ CASHCAT on 5 Aug 23:02 (his whale post). Saved to /tmp/fs/july_39.json this session. **None of the 39 bought RSRV, none held ZZZ at his post, one bought PARE (at $3.4M), two hold UBIK.** None is a counterparty of 0x643798a3 (69 counterparties, zero overlap)
- THE SEPTEMBER CLUSTER is still exactly one wallet, 0x643798a32806d6571daf5b664012409aeba11e0e, and it was born 22 Jul, after STONKBROKER launched
- **CONCLUSION: no single Robinhood Chain wallet does everything he said.** Either he runs two wallets (an older one for July, the fomo one since late July) or one of the two statement groups is not literal. 0x643798a3 remains the best candidate for the September statements only. Track it as "probably one of his", never as "his wallet"
- METHOD NOTES: the public RH RPC has NO archive state (balanceOf at an old block returns null), so a historical holder snapshot has to be rebuilt from logs. A 4M-log pull of CASHCAT (18 Jun to 5 Aug) killed the process when it tried to hold every leg; the fix that worked is /tmp/fs/balpull.py, which aggregates a balance Counter per chunk and never keeps the legs (43,354 holders, about 12 minutes). GeckoTerminal hourly OHLCV returns 401 with before_timestamp older than ~41 days; use the daily endpoint for older history. fomo's token Swaps tab shows "No activity yet" even at min $1K and its Holders tab lists only named wallets, so neither can surface an unnamed fomo wallet's trades

## 8 Sep 2026, PARE seller ledger cross-check ([[pare-stocks]])
- 0x643798a32806d6571daf5b664012409aeba11e0e acquired 21,859,765 PARE lifetime (first in block 52968303, the launch minute), sold 21,347,705 into venues, holds 0 at 03:43 UTC 8 Sep. fomosaurus posted 7 Sep 07:52 "Our initial $240 buys are valued around $100K", i.e. still holding. The wallet was flat again while he said he held: same shape as the 6 Sep "remain bullish while flat" mismatch. Confidence stays about 55%, leaning lower
