**一.首先将主网的ETH跨到Base主网（参与成本大概0.001GAS）**

1.在ETH链进行转账，转账地址：0x49048044D57e1C92A77f79988d21Fa8fAF74E97e，先输入金额（成本大概0.001，转的时候比成本多一些就行），然后提交就行，一分钟左右就能在Base主网浏览器查到.

**二.签名**

1.NFT需要在前端Mint,要生成自己的签名HASH，需要使用浏览器签名工具：\*\* [https://basescan.org/verifiedSignatures#](https://basescan.org/verifiedSignatures#) \*\*，进入官网，点击Sign Message,会弹窗口让你添加BASE主网
