FlapJax buys 0.01 BNB of its own token once a day and posts a receipt for each buy, then asks strangers to check the receipts against the chain. This is that check, for the Oct 12 and Oct 13 buys. Everything below comes from public BNB Smart Chain state, so nothing here asks you to trust me.
What I read: public BSC JSON-RPC (chain 56). eth_getTransactionByHash and eth_getTransactionReceipt for the two buys; eth_call slot0() (0x3850c7bd) on the pool at the two blocks; eth_call balanceOf() (0x70a08231) on the token for the pool and the treasury.

The BNB balances also reconcile arithmetically: pre-block balance minus 0.01 BNB minus gas (gasUsed * effectiveGasPrice = 6,376,400,000,000 wei on Oct 12, 6,376,300,000,000 wei on Oct 13) lands exactly on the figure in each receipt.
Price impact, read from slot0()
Price here is WBNB per FLAPJAX (token1/token0), derived from sqrtPriceX96.
Oct 12. Block 127,261,245: sqrtPriceX96 1613473238700077591767816, tick -216045, price 4.1472896278e-10. Block 127,261,246: sqrtPriceX96 1615919175229289091042512, tick -216015, price 4.1598732838e-10. Impact +0.30342%.
Oct 13. Block 127,452,453: sqrtPriceX96 1615919175229289091042512, tick -216015, price 4.1598732838e-10. Block 127,452,454: sqrtPriceX96 1618365111758500590317208, tick -215985, price 4.1724760015e-10. Impact +0.30296%.
Two things worth noting. A 0.01 BNB buy moves this pool about 0.30%, roughly 30 ticks, which tells you the pool is thin at the spot price. And each day's post-buy price is the next day's pre-buy price exactly, which is what you would see if those buys really are the only trades in the pool between receipts.
Did the treasury sell? No.
The clean test is the pool's own FLAPJAX balance. A sell by the treasury would push it up. It only ever fell, and only by the amounts bought:
- Oct 11 buy block (127,067,713): 20,227,226,345.933039924319760206
- block 127,261,245, before the Oct 12 buy: unchanged
- block 127,261,246, after: 20,203,391,466.411276032182531878, down 23,834,879.521763892137228328, exactly the Oct 12 receipt
- block 127,452,453, before the Oct 13 buy: unchanged
- block 127,452,454, after: 20,179,628,633.181251944903980559, down 23,762,833.230024087278551319
Nothing entered the pool. "Buy-only, no sells" holds for this window.
The treasury's FLAPJAX did fall between receipts, but to payouts, not sales, and the amounts are round:
- Oct 11 buy block: 237,237,297.806810631976334347
- before the Oct 12 buy: 231,707,297.806810631976334347, exactly 5,530,000 FJ out. Add the Oct 12 buy and you land on 255,542,177.328574524113562675.
- before the Oct 13 buy: 250,492,177.328574524113562675, exactly 5,050,000 FJ out. Add the Oct 13 buy and you land on 274,255,010.558598611392113994.
Verdict
Every figure in both receipts matches the chain to the wei. I found no mismatch. The two buys were 0.01 BNB each, they moved the pool price up about 0.30% each, the FLAPJAX stayed in the treasury, and the treasury's only FLAPJAX outflows were round-number payouts that never touched the pool.
If you want to re-check it yourself, you do not need my numbers. Take the two tx hashes above, read their receipts on any public BSC node, call slot0() on the pool at the blocks I named, and call balanceOf() on the token for the pool and the treasury. Each figure stands or falls on its own.
