课后练习

通过命令行，发行一个代币。并给自己账号mint一定数量的代币。 并通过插件钱包或者命令行的方式给其他同学空投该代币

提示：

• 命令行操作，查看spl-token命令的帮助文档

solana config set --url https://api.devnet.solana.com

示例

设置环境为开发环境：

创建账号：

solana-keygen new --force
Generating a new keypair

For added security, enter a BIP39 passphrase

NOTE! This passphrase improves security of the recovery seed phrase NOT the
keypair file itself, which is stored as insecure plain text

BIP39 Passphrase (empty for none):

Wrote new keypair to /Users/you/.config/solana/id.json
===========================================================================
pubkey: Czorr4y9oFvE3VdfCLVFuKDYxaNUG1iyQomR7kMZUuzi
===========================================================================
Save this seed phrase and your BIP39 passphrase to recover your new keypair:
tail ... despair
===========================================================================

因为这里是求取ATA账号，所以只需要提供Token Mint地址即刻。

去浏览器找一个其他地址，如BBy1K96Y3bohNeiZTHuQyB53LcfZv6NWCSWqQp89TiVu,这个是个SOL地址
