IPFS存文件
1、去中心化存储NFT的元数据
用这个网站https://www.pinata.cloud/ ,用来IPFS PIN files,笔者传了一个文件得到CID:
QmYgceyozYeZkeN5v1ZcS5rdpLxqWXrcLDCevT1FZyufaa
2、如何查看图片文件:
https://cloudflare-ipfs.com/ipfs/QmYgceyozYeZkeN5v1ZcS5rdpLxqWXrcLDCevT1FZyufaa
Cloudflare's IPFS gateway provides a read-only, HTTP-accessible interface to the Interplanetary File System (IPFS).
或者ipfs://QmYgceyozYeZkeN5v1ZcS5rdpLxqWXrcLDCevT1FZyufaa
这个可以在Brave浏览器直接打开,因为内置了IPFS节点。
如何开放合约源码
1、先去etherscan申请api key:
https://etherscan.io/login.aspx
2、当然可以直接在etherscan上按照提示一步步的进行verify and publish,然后填入合约源代码。这里使用另一种方式,用Hardhat:
申请etherscan的api key,然后在hardhat工程里:
npm i -D @nomiclabs/hardhat-etherscan
hardhat.config.js文件里添加:
require("@nomiclabs/hardhat-etherscan");
// Rest of code
...
module.exports = {
solidity: "0.8.17",
// Rest of the config
...,
etherscan: {
// Your API key for Etherscan
// Obtain one at https://etherscan.io/
apiKey: "",
}
};
执行verify
npx hardhat verify 0xd1f21ba617b622e290cd3c5d2a10193177c269fa --network goerli
报timeout,因为终端没有像浏览器一样走proxy,ClashX没法实现这个功能,下载安装ClashX Pro, 由于是基于前者的,所以安装之后配置自动就导入了不用重新配置。
ping api-goerli.etherscan.io 可以ping通了,重新执行verify:
$ npx hardhat verify 0xd1f21ba617b622e290cd3c5d2a10193177c269fa --network goerli
Nothing to compile
