CosmJs 支持

Injective 在 @cosmjs 包中没有原生支持。强烈建议使用我们的 @injectivelabs 包与 Injective 交互。 如果你熟悉 @cosmjs 包，我们导出了类似的接口/类，它们的工作方式与 @cosmjs 上的类相同，但也支持 Injective。 再次提醒，推荐的方法是使用 Injective 的标准方法，你可以在 Cosmos 交易中了解更多。

使用 Keplr

以下是如何使用 @injectivelabs 替代 @cosmjs 包与 Keplr 配合使用的示例：

import {
  PrivateKey,
  InjectiveStargate,
} from "@injectivelabs/sdk-ts/cosmjs";
import { OfflineDirectSigner } from "@cosmjs/proto-signing";
import { assertIsBroadcastTxSuccess } from '@cosmjs/stargate'
(async () => {
  // 启用 Keplr
  await window.keplr.enable(chainId);
  // 获取离线签名者
  const offlineSigner = window.getOfflineSigner(chainId);
  const [account] = await offlineSigner.getAccounts();
  // 初始化 stargate 客户端
  const client =
    await InjectiveStargate.InjectiveSigningStargateClient.connectWithSigner(
      "https://lcd-cosmoshub.keplr.app/rest",
      offlineSigner,
    );
  })
  const amount = {
    denom: "inj",
    amount: amount.toString(),
  };
  const fee = {
    amount: [
      {
        denom: "inj",
        amount: "5000000000000000",
      },
    ],
    gas: "200000",
  };
  const result = await client.sendTokens(
    account.address,
    recipient,
    [amount],
    fee,
    ""
  );
  assertIsBroadcastTxSuccess(result);
  if (result.code !== undefined && result.code !== 0) {
    alert("发送 tx 失败: " + result.log || result.rawLog);
  } else {
    alert("成功发送 tx:" + result.transactionHash);
  }
})()

在 CLI/Node 环境中使用

以下是如何在 node 或 CLI 环境中使用 @injectivelabs 替代 @cosmjs 包的示例。 再次提醒，推荐的方法是使用 MsgBroadcasterWithPk 抽象来遵循 Injective 的标准方法。

import {
  PrivateKey,
  InjectiveStargate,
  InjectiveDirectEthSecp256k1Wallet,
} from "@injectivelabs/sdk-ts/cosmjs";
import { getStdFee } from "@injectivelabs/utils";
import { OfflineDirectSigner } from "@cosmjs/proto-signing";
import { Network, getNetworkInfo } from "@injectivelabs/networks";
(async () => {
  const network = getNetworkInfo(Network.Testnet);
  const privateKeyHash = process.env.PRIVATE_KEY as string;
  const privateKey = PrivateKey.fromHex(privateKeyHash);
  const injectiveAddress = privateKey.toBech32();
  const wallet = (await InjectiveDirectEthSecp256k1Wallet.fromKey(
    Buffer.from(privateKeyHash, "hex")
  )) as OfflineDirectSigner;
  const [account] = await wallet.getAccounts();
  const client =
    await InjectiveStargate.InjectiveSigningStargateClient.connectWithSigner(
      network.rpc as string,
      wallet
    );
  const recipient = injectiveAddress;
  const amount = {
    denom: "inj",
    amount: "1000000000",
  };
  const txResponse = await client.sendTokens(
    account.address,
    recipient,
    [amount],
    getStdFee(),
    "祝你的星币玩得开心"
  );
  if (txResponse.code !== 0) {
    console.log(`交易失败: ${txResponse.rawLog}`);
  } else {
    console.log(
      `广播的交易哈希: ${JSON.stringify(
        txResponse.transactionHash
      )}`
    );
  }
})();
