Bank - Injective Docs

bank 模块负责处理账户之间的多资产代币转移，并跟踪必须以不同方式工作的特殊情况伪转移（特别是 vesting 账户的委托/取消委托）。它暴露了几个具有不同功能的接口，用于与必须更改用户余额的其他模块进行安全交互。此外，bank 模块跟踪并提供对应用程序中使用的所有资产总供应量的查询支持。

消息

让我们探索（并提供示例）Bank 模块导出的消息，我们可以使用这些消息与 Injective 链交互。

MsgSend

此消息用于从一个地址向另一个地址发送代币。任何 TokenFactory 代币和 Peggy 代币都可以在这里使用。要转移 CW20 代币，请参阅 wasm 模块示例中的 MsgExecuteContract 部分。

import { Network } from "@injectivelabs/networks";
import { toChainFormat } from "@injectivelabs/utils";
import { MsgSend } from "@injectivelabs/sdk-ts/core/modules";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";

const privateKey = "0x...";
const injectiveAddress = "inj1...";
const amount = {
  denom: "inj",
  amount: toChainFormat(1).toFixed(),
};
const msg = MsgSend.fromJSON({
  amount,
  srcInjectiveAddress: injectiveAddress,
  dstInjectiveAddress: injectiveAddress,
});

const txHash = await new MsgBroadcasterWithPk({
  privateKey,
  network: Network.Testnet,
}).broadcast({
  msgs: msg,
});

console.log(txHash);

MsgMultiSend

此消息用于从多个发送者向多个接收者发送。

import { Network } from "@injectivelabs/networks";
import { toChainFormat } from "@injectivelabs/utils";
import { MsgMultiSend } from "@injectivelabs/sdk-ts/core/modules";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";

const privateKey = "0x...";
const injectiveAddress = "inj1...";
const denom = "inj";
const decimals = 18;
const records = [
  /** 在此添加记录 */
] as {
  address: string;
  amount: string /* 人类可读的数字 */;
}[];
const totalToSend = records.reduce((acc, record) => {
  return acc.plus(toChainFormat(record.amount, decimals));
}, toChainFormat(0));

const msg = MsgMultiSend.fromJSON({
  inputs: [
    {
      address: injectiveAddress,
      coins: [
        {
          denom,
          amount: totalToSend.toFixed(),
        },
      ],
    },
  ],
  outputs: records.map((record) => {
    return {
      address: record.address,
      coins: [
        {
          amount: toChainFormat(record.amount, decimals).toFixed(),
          denom,
        },
      ],
    };
  }),
});

const txHash = await new MsgBroadcasterWithPk({
  privateKey,
  network: Network.Testnet,
}).broadcast({
  msgs: msg,
});

console.log(txHash);
