# @sonder_crypto wallet hunt (7 Sep 2026)

[stated] Ben asked: "find his wallets. not his fomo wallet but his robinhood wallet. use his twitter posts and replies with timestamps and coin mentions."

## Proven
- fomo user id `7b9a6506-ba02-5030-aae5-dd735a68ac68`, handle sonder_crypto, "Joined Apr 2025", 1,451 trades, $6.23M volume, clan "Sparsity".
- Robinhood Chain fomo wallet = `0x82b270406d88d4615374af31acd7be031a8a9212` (EIP-7702 code `0xef0100e6…`, nonce 219). Proof: FIRE balance 65,802,202 = fomo profile "65.8M FIRE"; fomo API FIRE buys 7 Sep 16:19 (37,832) and 16:49 (94,060) land in this address to the token; CUM/GLD buys 23:00 to 23:18 vs tweet 23:13 UTC 1 Sep; CUM/USAR switch 05:11 vs tweet 05:23 2 Sep; ANALYST buys 00:52 vs "I am an $ANALYST" 01:11 3 Sep; CATAMINE buys 18:40 to 22:30 vs nomination 22:43 3 Sep; GASOLINU buys 19:04 vs "gas it" 19:06 4 Sep.
- fomo Solana wallet `8rz5qXHh5raQbiJ4bRrBGb8uuasKzH5gQMxPsNuQQj5x`. fomo record also lists evmAddress `0x042b0dbc76ad1e78086f01c4b5a84a3e4d999017` and RH trade address `0xfc11ca3f0cff98d6bc31e61c7df8924ab8fdff03`, both EMPTY on chain (internal ids, not wallets).
- "Rabby" = the same key. 0x82b2 signs 105 of its 2,067 txs itself (fomo fills are relayer-sent): 36 to 1inch router `0x5a705de8982235a7fa45bb83dcacf03a211389c7` (sel 0x07ed2379), 25 to `0x20f6ee51340adeed01a59b0e65cb3703f3dc860c`, 23 to `0x02e5be68d46dac0b524905bff209cf47ee6db2a9`, 15 FIRE buys with ETH via `0x6131b5fae19ea4f9d964eac0408e4408b66337b5`; each preceded by a gas top-up from `0x91604f590d66ace8975eed6bd16cf55647d1c499` (nonce 106,849, a gas service). Other fomo wallets (Uber M `0xcf6cdf01…`, `0x4609aa82…`) have zero such txs, so this is not a fomo feature.
- FIRE co-runner ("I'm running it with dev friend", 5 Aug). FIRE distributor EOA `0xacc79e7b9f8dbb22e197c76d92ff8c0472ac81b4` airdropped 1:1 to Base holders on 18 Jul; 0x82b2 got 40,412,212 (his "4%").
- `0xcd6b980029e6e6e0733ac8ec3e02be9410d09799` (nonce 58k) is an aggregator FEE COLLECTOR, not a wallet.

## Not found
- A separate wallet for his July first-wave trades (CASHCAT at $4M day 1, HOODRAT ~$350K, TENDIES ~$3M, INDEX after Vlad tweet, PONS sold ~$10M, AI added 23 Jul 22:39). 0x82b2 has nothing on RH before 11 Jul. Swept CASHCAT/HOODRAT/TENDIES/PONS/INDEX/AI transfer logs in dated windows and intersected: no single EOA matches all; best partial fits were `0xff2bcd8e3a12d6930518a45519da1c5e67129948` (day-1 CASHCAT, PONS, AI 19:54 23 Jul, holds AI+ANALYST+CASHCAT, but flipped HOODRAT/TENDIES same night 8 Jul) and `0x5ec560396f7a6f9292c4e8c479ea9c291bc7d179` (TENDIES sold 21:25 vs tweet 21:46 16 Jul, but no AI on 23 Jul). Neither proven.

## Method notes (reusable)
- fomo API from the logged-in fomo.family tab: `prod-api.fomo.family/v2/users/userHandle/{handle}` gives id + evmAddress; `/trades?userId=&orderBy=closedAt|realizedPnlUsd&networkId=4663` (RH = 4663, Solana 1399811149, Base 8453, BSC 56) gives userAddress per trade; `/v2/users/{id}/swaps?limit=100`; `/v2/users/{id}/balances`. MUST send header `X-Supported-Chains: 1,56,143,4663,8453,1399811149` or EVM data is hidden. Bearer = localStorage `privy:token`. No working pagination found (limit max 25 on trades, 100 on swaps).
- Blockscout API blocks the container (403) but works from the Chrome tab via same-origin fetch on robinhoodchain.blockscout.com `/api/v2/addresses/{a}/transactions?filter=to|from`.
- RH block-time is not linear early on; for dated windows use block_at() binary search at both edges, never interpolate across days.
