密钥对和钱包

如何生成新的密钥对

对于使用Solana库执行各种操作,许多操作都需要一个密钥对或钱包。如果你正在连接到一个钱包,那么你不必担心。然而,如果你需要一个密钥对,你会需要生成一个。

如何从密钥恢复密钥对

如果你已经有了密钥,你可以通过这个密钥获取密钥对,以测试你的dApp。

  1. 从字节中:

如何检查一个公钥是否有关联的私钥

在某些特殊情况下(例如,派生自程序的地址(PDA)),公钥可能没有关联的私钥。你可以通过查看公钥是否位于ed25519曲线上来检查这一点。只有位于曲线上的公钥才可以由具有钱包的用户控制。

如何生成助记词

如果你正在创建一个钱包,你需要生成一个助记词,以便用户可以将其保存为备份。

如何通过助记词恢复密钥对

许多钱包扩展使用助记词来表示其密钥。你可以将助记词转换为密钥对以进行本地测试。

  const mnemonic =
    "pill tomorrow foster begin walnut borrow virtual kick shift mutual shoe scatter";
  const seed = bip39.mnemonicToSeedSync(mnemonic, ""); // (mnemonic, password)
  const keypair = Keypair.fromSeed(seed.slice(0, 32));
  console.log(`${keypair.publicKey.toBase58()}`); // 5ZWj7a1f8tWkjBESHKgrLmXshuXxqeY9SYcfbshpAqPG
})();
from solders.keypair import Keypair

keypair = Keypair.from_bytes(seed)
print("Created Keypair with Public Key: {}".format(keypair.pubkey()))

如何生成自定义地址(vanity address)

自定义公钥或地址(Vanity Address)是以特定字符开头的密钥。例如,一个人可能希望公钥以 "elv1s" 或 "cook" 开头,这样可以帮助他人记住密钥所属的人,使密钥更容易识别。

注意: 自定义地址中字符的数量越多,生成时间将会更长。

如何连接到钱包

Solana的钱包适配器open in new window 库使客户端管理钱包连接变得简单。

反应

运行以下命令来安装所需的依赖项:

yarn add @solana/wallet-adapter-react @solana/wallet-adapter-react-ui @solana/wallet-adapter-base @solana/wallet-adapter-wallets

React的钱包适配器库允许我们通过钩子和上下文提供程序来持久化和访问钱包连接状态,主要包括useWallet、WalletProvideruseConnection和ConnectionProviderWalletProviderConnectionProvider必须包装React应用程。

此外,我们可以使用useWalletModal来提示用户进行连接,通过切换连接模态框的可见性,并将应用程序包装在@solana/wallet-adapter-react-ui中的WalletModalProvider中。连接模态框将处理连接流程,因此我们只需监听钱包连接的状态。当useWallet的响应具有非空的wallet属性时,我们知道钱包已连接。反之,如果该属性为空,我们知道钱包已断开连接。

};
initWallet(wallets);

const { connected, wallet } = useWallet();
</script>

  <div>
    <p v-if="connected">
      Wallet with public key {{ wallet.publicKey }} successfully connected!
