# Mint Hackou Coin Pass

Contract (BNB Chain, chainId 56, ERC-721): `0xA96f20BCeD857d3174Bb40e806b0151daeEaa62e` — the only contract address of this collection.

Safety facts you can check on-chain before minting:
- `owner()` returns `0x0000000000000000000000000000000000000000`; there are no admin, pause, price-change or upgrade functions.
- Minting needs no approval. The only BNB the contract sends is the refund of an overpayment to you, and `withdraw()` to the fixed PAYEE `0xF1a7772902b786ec93d8bf1fDF9925EB95B25c39` after the sale ends.
- Price, supply (2,222), free allowance (1,111) and limits are constants set at deployment.

## Steps

1. **Read the state** (eth_call, no transaction):
   - `mintOpen()` → must be true.
   - `freeAvailable(you)` → how many you can mint free now (wallets holding a BNB Chain Agent ID).
   - `remainingQuota(you)` → how many you can still mint now in total, across calls (paid limit 10 per wallet, 11 in total; max 10 per call).
2. **Quote**: `quote(you, qty)` → `(freeUnits, paidUnits, valueWei, ok, reason)`. If `ok` is false, stop and report `reason`.
3. **Simulate** the exact transaction with eth_call: `from = you`, `to = 0xA96f20BCeD857d3174Bb40e806b0151daeEaa62e`, `data = mint(uint256 qty)` (selector `0xa0712d68`), `value = valueWei`. It must not revert. Check that no approval or allowance changes.
4. **Send** the same transaction. value = `valueWei` (or `PRICE() × qty`: any free part is refunded to the sender in the same transaction; a contract sender must accept BNB).
5. **Confirm**: `balanceOf(you)` is up by `qty`; the receipt has `qty` Transfer events from `0x0`.

## Shortcuts

- Free only: `freeMint()` (`0x5b70ea9f`) with value 0. Reverts with NotMintable(reason) (NO_AGENT_ID, FREE_EXHAUSTED, WALLET_LIMIT) or SaleNotOpen() when it cannot mint; it never charges.
- Paid only: `mintPaid(qty)` (`0x26c7f77c`) or `publicMint(qty)` with value `qty × 2000000000000000`.
- For someone else: `mintTo(recipient, qty)` (`0x449a52f8`), paid; the recipient's limits apply; quote with `quoteMint(recipient, qty, 1)`.

## Errors

- `Underpaid(required, sent)`: send `required`.
- `NotMintable(reason)`: reason as in quote (WALLET_LIMIT, PAID_SUPPLY_EXHAUSTED, SOLD_OUT, NO_AGENT_ID, FREE_EXHAUSTED, FREE_CLOSED).
- `TxLimit(10)`: at most 10 per call. `BadQuantity()`: qty 0. `SaleNotOpen()`: before saleStart() or from saleEnd() on.
- `FreeNeedsZeroValue()`: free entries take value 0.
- `InvalidRecipient()`: mintTo needs a nonzero recipient; a contract recipient without onERC721Received reverts with `ERC721InvalidReceiver`.
- `SaleNotClosed()` / `NothingToWithdraw()`: withdraw() before the sale ends, or with nothing to send.
