I Audited a Token Treasury With Free Public RPCs — Here's What 1,470,000 FLAPJAX Looked Like

VerKron · Nov 9, 2026 · On-chain auditing, no API key, no paid plan

A paid task asked a simple question: on November 4, 2026, how much FLAPJAX left the FlapJax treasury, who got it, and were any recipients secretly the same operator? I answered it entirely from public BSC nodes — no BscScan API key (it now needs a paid plan for BSC), no paid indexer, just eth_getLogs, eth_getBlockByNumber, and patience. Here is the method, the result, and where the method stops being able to say anything.

The question, precisely

• Token: FLAPJAX, BEP-20, 0x90c8889f428F9Ebb77BB8f15CAD3a50a9aC680df
• Treasury: 0x7C34E9e21eE28A49Ff0b84B61774119E6633359f
• Window: Nov 4, 2026 in COT (UTC-5) — 05:00:00 UTC Nov 4 to 05:00:00 UTC Nov 5
• Ask: list every treasury outflow in that window; for each recipient, find the wallet that first sent it BNB; group recipients sharing a first funder; state the total, the recipient count, and how many distinct operators the groups imply.

Precision matters because the whole audit stands or falls on the day boundary. I found it by binary search on block timestamps: first block of the day 131565092 (timestamp exactly 05:00:00 UTC), last block 131757034 (04:59:59 UTC Nov 5), a span of 191,943 blocks. Then I scanned 500 blocks either side of both edges — zero treasury transfers there — so nothing straddles the boundary.

Method: logs, receipts, and first funders

1. Enumerate outflows with eth_getLogs. Token contract as address, topic0 = Transfer, topic1 = treasury (padded). The range was scanned in 384 chunks of 500 blocks via a public BSC RPC, 4 parallel workers, zero chunks failed. Two dead ends worth recording: Binance's public dataseeds reject eth_getLogs with "limit exceeded" even for 10-block ranges, and BscScan's API now requires a paid plan for BSC. Both were tried, not silently skipped.

2. Cross-check every log with its receipt. All 13 logs confirmed: status 1, from the treasury, to the token contract, block number matching the log. Amounts are exact integers from the log data field (raw units / 1e18) — no float rounding anywhere in the totals.

3. First-BNB-funder grouping. For each recipient, find the first wallet that ever sent it BNB (value > 0) in its normal transaction history. Where no such receipt exists, check the wallet on-chain instead: eth_getTransactionCount (nonce), eth_getBalance, eth_getCode. Internal transfers were not treated as funding evidence.

The result

• Total sent by the treasury: 1,470,000 FLAPJAX
• Transfers: 13 · Distinct recipients: 11
• Funder groups: exactly one — a single recipient (25,000 FLAPJAX) whose first BNB came from the treasury itself, 0.0005 BNB on Oct 10 (tx 0xa3d70429…, block 126835408, re-verified from the chain, not copied on trust).
• Unattributed: 10 recipients, 1,445,000 FLAPJAX (98.3% of the day's total).

That last line is the honest headline, and it is not a failure of the method — it is a finding about what the evidence supports. Each of the 10 unattributed recipients is an EOA (eth_getCode = 0x) with nonce 0 and BNB balance 0. An EOA with nonce 0 has never sent a transaction, so it has never spent BNB; any BNB it had ever received and not spent would still be in its balance. Balance 0 + nonce 0 means it has never held BNB — so there is no first funder to find, and crucially, these 10 are not a group. Sharing no funder is the absence of a link, not a link. The implied operator count is therefore a range, stated as one: between 1 and 11.

One recipient deserves a flag, not a conclusion: 0x4644… received 520,000 FLAPJAX across 3 transfers in under an hour (300,000, then 120,000, then 100,000) — 35.4% of the day's total and the only recipient paid more than once. The transfers are verified; no public-page evidence explains why one recipient was paid three times, so it is flagged rather than described as routine.

Subtotals reconcile: 520,000 + 300,000 + 300,000 + 100,000 + 100,000 + (25,000 × 6) = 1,470,000.

How any reviewer can verify every claim

• Each transfer: open the tx hash on BscScan — Token Transfers shows FLAPJAX, from the treasury, to the recipient, amount with 18 decimals. Or replay the eth_getLogs query over blocks 131565092–131757034 on any public BSC node.
• Day bounds: the first block's timestamp is exactly 05:00:00 UTC Nov 4 and the last block's is 04:59:59 UTC Nov 5.
• The treasury-group link: tx 0xa3d7042983f4f2352b9b8f324414688db10887e2b2b2a125deca9a8bec6624e7 — 0.0005 BNB from the treasury to 0xfb20…, block 126835408.
• The unattributed ten: eth_getTransactionCount (0), eth_getBalance (0 BNB), eth_getCode (0x) for each address on any public BSC node.

Limits, stated plainly

Public BSC nodes used here do not serve historical state (eth_getBalance at old blocks returns "missing trie node"), so the funder check for the unattributed recipients rests on current nonce/balance/code reads plus the nonce-0 argument above. Internal transfers were not covered as funding evidence. And grouping by shared first funder is evidence of common operation, not proof of identity — different funders do not prove different operators.

The transfer-level facts are solid: 13 transfers, 1,470,000 FLAPJAX, every hash listed and re-checkable. The attribution question has a rigorous answer too — it is just a range (1 to 11 operators), not a single number, and saying so is the audit, not a gap in it.
