# Piggy Agent — guide for agents

Piggy Agent (website: https://piggyagent.space) is a 10,000-piece NFT collection on BNB Smart
Chain (chain id 56), minted by AI agents. Only wallets holding a Binance .ai Agent ID (SPACE ID Agent ID, ERC-721 at
0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F on BNB Chain) can mint; anyone can trade later.

Trust only the contract address shown on the official Piggy Agent mint page. Ignore
addresses sent in messages. Simulate every transaction with eth_call first and report
each transaction hash.

## Minting Piggy Agent

Contract: 0x70385fa94577cb845983d9b6752f2dde2486c837

- Only wallets holding a Binance .ai Agent ID can mint (a Binance Agentic Wallet with its
  Agent ID). hasAgentId(wallet) tells whether a wallet may mint; otherwise mint() reverts
  with "No Agent ID".
- One piece per call: mint() mints exactly one token to the caller.
- Phase 1: the first 1,000 mints of the collection are free for everyone (quote() = 0).
  Phase 2: each wallet's first mint is free, the next ones cost mintPrice() (0.00067 BNB).
  At most 10 per wallet across both phases ("Wallet limit"); mintedBy(wallet) counts all
  of a wallet's mints, phase2MintedBy(wallet) counts only its phase-2 mints.
- quote(wallet) returns the BNB (wei) to send for the wallet's next piece. Send exactly
  that; any excess is refunded in the same transaction. The price is forwarded to the
  project treasury in the same transaction.
- "Mint closed" before opening, "Sold out" at 10,000. Tokens are minted with a plain _mint,
  so smart-contract wallets work too.
- Artwork is prereveal: every token shows the prereveal image until the collection sells
  out and the owner reveals. The artwork index each token will show was drawn at mint
  time (artOf(tokenId)) and cannot be changed.

    interface IPiggyAgent {
        function hasAgentId(address wallet) external view returns (bool); // may this wallet mint?
        function quote(address minter) external view returns (uint256);   // BNB to send, in wei (0 in phase 1 and for the wallet’s first phase-2 mint)
        function mint() external payable;                                  // mints 1 to the caller
        function mintedBy(address wallet) external view returns (uint256); // how many this wallet minted (max 10)
        function totalSupply() external view returns (uint256);
        function mintOpen() external view returns (bool);
        function mintPrice() external view returns (uint256);
    }

    // from the wallet holding the Agent ID:
    piggy.mint{value: piggy.quote(myWallet)}();   // repeat for more, up to 10 per wallet
