20+ 从0开始构造DApp
21+
22+ 1 . 本次演示的GitHub代码库:https://github.com/0xhardman/handmade-nft-frontend
23+
24+ https://github.com/0xhardman/foundry-simple-nft
25+
26+ 活动官方仓库地址: https://github.com/CasualHackathon/MyFirstDApp
27+
28+ hardman老师的社交媒体链接: https://x.com/0xhardman
29+
30+ 2 . 手把手教写代码:

40+ source .env && forge verify-contract 0x2aF278c3EE57620cb82ce19bD5b3E3d696ADEb01 src/SimpleNFT.sol: SimpleNFT \
41+
42+ source .env && forge script script/DeploySimpleNFT.s.sol --rpc-url $SEPOLIA_RPC_URL \
43+
44+ - -broadcast --verify
45+
46+ ```
47+ --etherscan-api-key $ETHERSCAN_API_KEY \\
48+
49+ --chain sepolia
50+ ```
51+
52+ 3. Q & A
53+
54+ 预言机是什么:可以理解为-?我就喜欢foundry可以用solidity去写测试
55+
56+ 区块链后端?:理解为后端就是区块链了
57+
58+ ai?:你得熟悉流程,把任务拆给ai,再去让ai帮你写代码。推荐Windsurf cursor Claude code
