今天的新SB我昨天个群里的小伙伴们安利了一只Shiba狗，太太也说这狗挺好看的，我赶快的加到我的shopping list里面。 他的网站是 https://www.shiba-beast.io/ ，同时他的discord是满的，非常的牛逼亚。抽奖了在他的Twitter上，项目方放了一个抽奖链接，我用自己的一个钱包注册了一下。但是我发觉这个钱包注册并没有发出任何的请求出去，仅仅是一个签名。开奖了PST 11:00am的时候，可以mint了，我竟然中了，可以mint 3个呢，每个要我0.3e。不过因为之前有过怀疑，觉得这个项目方太fishy了，我就没有见过discrod满的项目，我也没有见过我可以中奖的抽奖！所以我打算先看看他们的合约： 我们再看看代码 https://etherscan.io/address/0xe3155db13b2be4866b7723b1458eb9611b838930#code%23L1// ========== SB CONTRACT MINTER ========== function SHIBABEAST_MINT(uint256 _MINT_AMOUNT) public payable nonReentrant { require(!PAUSE, "SHIBABEAST CONTRACT IS PAUSED"); uint256 MINTED_SUPPLY = totalSupply(); require(_MINT_AMOUNT > 0, "MINT AMOUNT SHOULD BE AT LEAST 1"); require(MINTED_SUPPLY + _MINT_AMOUNT <= SUPPLY, "MAX SUPPLY EXCEEDED"); if (msg.sender != owner()) { require(_MINT_AMOUNT <= 5, "MAX PER TRANSACTION EXCEEDED"); require(msg.value >= COST * _MINT_AMOUNT, "INSUFFICIENT FUNDS"); } uint256 _NEW_TOKEN_ID; for (uint256 i = 1; i <= _MINT_AMOUNT; i++) { _TOKEN_IDS.increment(); _NEW_TOKEN_ID = _TOKEN_IDS.current(); _safeMint(msg.sender, _NEW_TOKEN_ID); } } /** * @dev Same as {xref-ERC721-_safeMint-address-uint256-}[`_safeMint`], with an additional `data` parameter which is * forwarded in {IERC721Receiver-onERC721Received} to contract recipients. */ function _safeMint( address to, uint256 tokenId, bytes memory _data ) internal virtual { _mint(to, tokenId); require( _checkOnERC721Received(address(0), to, tokenId, _data), "ERC721: transfer to non ERC721Receiver implementer" ); } /** * @dev Mints `tokenId` and transfers it to `to`. * * WARNING: Usage of this method is discouraged, use {_safeMint} whenever possible * * Requirements: * * - `tokenId` must not exist. * - `to` cannot be the zero address. * * Emits a {Transfer} event. */ function _mint(address to, uint256 tokenId) internal virtual { require(to != address(0), "ERC721: mint to the zero address"); require(!_exists(tokenId), "ERC721: token already minted"); _beforeTokenTransfer(address(0), to, tokenId); _balances[to] += 1; _owners[tokenId] = to; emit Transfer(address(0), to, tokenId); } /** 恩。。每次可以mint 5个，但是没有限制每个钱包可以有多少个。慢着，为啥没有白名单检查？为啥没有中奖检查？ 在看看opensea上的情况0.1e的地板价，其实我看的时候是0.01….你们心不疼吗？还是说你们也发觉风险太大，想收回点成本呢？后记我突然可以进入他们的discord了，完全没有热度。我不好评论这个项目，但是我是决定不碰了，按照我们的说法：没有这么大只青蛙满街跳！
