部署合约一次铸造多个NFT

February 19th, 2022

在Matic上有个项目的会员NFT可以让一个钱包免费铸造一个: https://meta.esportsone.com/claim

想到之前学到的部署合约多领空投的合约，虽然那一个是领取代币，而这次是领取NFT，但是原理是一样的，所以打着学以致用的道理改了一下合约代码

很顺利一次性领取了200个NFT，费用也还好，花了总共0.53 matic，比一个个领便宜一些

合约代码:

pragma solidity ^0.8.0;

interface passNFT {
    function claim(address receiver,uint256 tokenId,uint256 quantity,bytes32[] calldata proofs) external;
}
contract multiCall {
    address constant contra = address(0x4867f7ACb9078d2b462442c5ca3DBa01456844B5);
    function call(uint256 times) public {
        for(uint i=0;i<times;++i){
            new claimer(contra);
        }
    }
}
contract claimer{
    constructor(address contra){
        bytes32[] memory proofs;
        passNFT(contra).claim(address(tx.origin),2,1,proofs);
        selfdestruct(payable(address(msg.sender)));
    }
}

部署好后，调用call函数，call(200) 就是铸造200个NFT

200个NFT铸造好后，全部发到调用合约的钱包，绕过1个钱包只能铸造一个NFT的限制

注: 这个会员可以无限制铸造，没有啥价值
