创建钱包

钱包可以在SDK中以多种方式创建。

生成新钱包

要生成一个新的、未锁定的钱包，可以使用generate方法。此方法创建一个新实例的WalletUnlocked，可以直接使用。

const unlockedWallet: WalletUnlocked = Wallet.generate();

创建未锁定钱包

创建现有的WalletUnlocked实例非常简单，可以通过以下几种方式：

从私钥创建：

const privateKey = '0x36ca81ba70f3e04b7cc8780bff42d907ebca508097d4ae3df5147c93fd217f7c';

const myWallet: WalletUnlocked = Wallet.fromPrivateKey(privateKey);

从助记词创建：

const mnemonic = 'section gospel lady april mouse huge prosper boy urge fox tackle orient';

const myWallet: WalletUnlocked = Wallet.fromMnemonic(mnemonic);

从种子创建：

const mySeed = '0xa5d42fd0cf8825fc846b2f257887a515573ee5b779e99f060dc945b3d5504bca';

const myWallet: WalletUnlocked = Wallet.fromSeed(mySeed);

从Hierarchical Deterministic (HD)派生密钥创建：

const mySeed = '0xa5d42fd0cf8825fc846b2f257887a515573ee5b779e99f060dc945b3d5504bca';

const extendedKey = HDWallet.fromSeed(mySeed).toExtendedKey();

const myWallet: WalletUnlocked = Wallet.fromExtendedKey(extendedKey);

从JSON钱包创建：

const jsonWallet = `{"id":"83d1792f-3230-496a-92af-3b44a1524fd6","version":3,"address":"ada436e1b80f855f94d678771c384504e46335f571aa244f11b5a70fe3e61644","crypto":{"cipher":"aes-128-ctr","mac":"6911499ec31a6a6d240220971730374396efd666bd34123d4e3ce85e4cf248c6","cipherparams":{"iv":"40576cbd4f7c84e88b0532320e23b425"},"ciphertext":"3e5e77f23444aa86b397dbc62e14d8b7d3fd7c7fe209e066bb7df17eca398129","kdf":"scrypt","kdfparams":{"dklen":32,"n":8192,"p":1,"r":8,"salt":"b046520d85090ee2abd6285174f37bc01e28846b6bb5edc03ae5f7c13aec03d2"}}}`;

const password = 'password';

const myWallet: WalletUnlocked = await Wallet.fromEncryptedJson(jsonWallet, password);

可以从 WalletLocked 实例化一个 WalletUnlocked创建：

const address = 'fuel1fjett54ahnydhklerngqhclzmmkmp6s0xnykns8dwsdpjfg3r2rsfazpw5';
const privateKey = '0x9deba03f08676716e3a4247797672d8008a5198d183048be65415ef89447b890';

const lockedWallet: WalletLocked = Wallet.fromAddress(address);

const unlockedWallet: WalletUnlocked = lockedWallet.unlock(privateKey);

创建锁定钱包

您还可以仅使用钱包地址创建WalletLocked实例：

const myWallet: WalletLocked = Wallet.fromAddress(address, provider);

连接到 Provider

虽然钱包可以独立于Provider使用，但需要与区块链交互的操作将需要一个Provider。

连接现有钱包到Provider：

const provider = await Provider.create('https://beta-5.fuel.network/graphql');

myWallet.connect(provider);

带Provider的实例化钱包：

const myWallet: WalletLocked = Wallet.fromAddress(address, provider);
