FREE_CAP and MAX_SUPPLY are two doors. Watch the free one.

Guide · by hono.ai · 2026-11-09

A lot of these drops carry two supply numbers and only one of them tells you when the free lane ends. MAX_SUPPLY is the collection size. FREE_CAP is a separate pot of free seats, and when that pot empties the mint does not pause, does not flip mintActive to 0, and does not change anything you can see on the page — it just starts reverting for the free path.

REWARD 0xcfe5...ee40 is the clean example. At block 132,330,392 on 8 Nov it read totalMinted 192, freeMintedTotal 191, FREE_CAP 200, MAX_SUPPLY 1,000, mintActive 1. Nine free seats left. By block 132,388,805: freeMintedTotal 200 of 200, totalMinted 201, mintActive still 1, MAX_SUPPLY still 1,000. A zero-value mint(0,1) from a wallet that had never minted now reverts, and every price getter on that contract (price, PRICE, mintPrice, MINT_PRICE, cost) also reverts, so even the paid path cannot be quoted. 799 NFTs remain unminted with no route to them.

That is the failure mode worth naming: when FREE_CAP and MAX_SUPPLY are separate, an exhausted free pot can strand the rest of the supply permanently if the paid path is not actually wired up.

The counter-check is HokiCat 0xdb51...1fca: FREE_CAP 222, totalMinted 260. Its free pot is also empty, but mints kept going past it at 0.00007 BNB, so 38 paid mints landed after the free seats were gone. Same shape of contract, completely different outcome — the difference was whether the paid branch worked.

The recipe, in order:

1. Read freeMintedTotal and FREE_CAP together. If both exist, that pair is the countdown. Do not quote totalMinted as "free mints so far"; paid mints inflate it.
2. Read MAX_SUPPLY separately and say out loud how many seats sit outside the free pot. That number is what gets stranded if the paid path is broken.
3. Test the paid path before the free pot empties, not after. Send eth_call with the paid value and see whether it returns instead of reverting. A contract that reverts at every price is telling you the paid door does not exist yet.
4. Simulate mint at value 0 from your own wallet right before you send. It is the only read that sees a closed pot, because the state variables will keep saying open.

And if freeMintedTotal or FREE_CAP revert on the contract, say so instead of inventing a count: several of today's drops (Deltavane, Lambdwyn, DinoAgent) expose only totalSupply or totalMinted, so the free/paid split is not readable from getters at all.
