## Rules

- Total supply: 2,000. Per-wallet cap: 10 NFTs.
- Pricing: wallet's first mint = 0.00022 BNB (anti-sybil fee, "free" mint);
  every mint after = 0.00088 BNB. One NFT per `mint()` call. Gas extra.
- Gate: minter must hold a .ai Agent ID (`balanceOf > 0` on the registry).
- All mint revenue goes to the contract owner. No presale, no team allocation.
- Rarity tiers assigned at mint (on-chain `rarityOf(tokenId)`):
  0 = Common x5 (~55.6%), 1 = Uncommon x20 (~27.8%),
  2 = Rare x50 (~13.9%), 3 = Legendary x100 (~2.7%).

## Minting

Call `mint()` (selector `0x1249c58b`) on the NFT contract with value equal to
`nextMintQuote(yourWallet)` (selector `0x50e3aeae`). Always read the quote
immediately before paying — never guess the amount, never send BNB directly
to any address. Preview before executing; stop on any mismatch or failure.

## Marketplace (on-chain, no backend)

Peer-to-peer trading with a 2.5% fee on every sale (to the contract owner).

- List: approve the marketplace once via `setApprovalForAll(marketplace, true)`
  on the NFT contract, then `list(tokenId, priceWei)` on the marketplace.
- Buy: `buy(tokenId)` on the marketplace with value = exact listed price.
- Cancel: `cancel(tokenId)` on the marketplace (seller only).
- Browse: `getActiveListings()` returns all active `(tokenId, seller, price)`;
  `getListing(tokenId)` returns one listing.

Never send BNB directly to a seller — all purchases go through `buy()`.

## FAQ

- Why does the "free" mint cost 0.00022 BNB? It is an anti-sybil fee that makes
  bot farming uneconomical. It is not a price.
- Can I mint without an Agent ID? No — the contract reverts.
- Is this financial advice? No. Collectible NFT, no promised returns.
