# Wasm

`wasm` 模块是与部署在 injective 链上的 wasm 智能合约交互的核心，您可以在这里找到部署在 Injective 链上的[智能合约](https://injscan.com/smart-contracts/)列表。

  `MsgUpdateCode` 和 `MsgStoreCode` 不被以太坊（如 Metamask）钱包支持。

## 消息

### MsgExecuteContract (Transfer)

此消息用于执行合约函数，下面我们将使用 [CW20 规范](https://github.com/CosmWasm/cw-plus/blob/main/packages/cw20/README.md) 的 transfer 消息作为示例。

```ts theme={null}
import { Network } from "@injectivelabs/networks";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";
import { MsgExecuteContract } from "@injectivelabs/sdk-ts/core/modules";

const injectiveAddress = "inj1...";
const recipientAddress = "inj2...";
const contractAddress = "cw...";

const msg = MsgExecuteContract.fromJSON({
  contractAddress,
  sender: injectiveAddress,
  exec: {
    action: "transfer",
    msg: {
      recipient: recipientAddress,
      amount: 100000,
    },
  },
});

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

console.log(txHash);
```

### MsgExecuteContract (funds 示例)

在某些场景中，根据智能合约的函数，我们必须将代币转移到智能合约，按照 cosmwasm 惯例，我们使用 funds 字段将代币从用户的 bank 模块转移到智能合约。

以下是使用 `test` 合约函数发送 `MsgExecuteContract` 的示例。

```ts theme={null}
import { Network } from "@injectivelabs/networks";
import { toChainFormat } from "@injectivelabs/utils";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";
import { MsgExecuteContract } from "@injectivelabs/sdk-ts/core/modules";

const injectiveAddress = "inj1...";
const contractAddress = "cw...";

const msg = MsgExecuteContract.fromJSON({
  contractAddress,
  sender: injectiveAddress,
  exec: {
    action: "test",
    funds: [
      {
        denom: "inj",
        amount: toChainFormat(1).toFixed(),
      },
    ],
  },
});

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

console.log(txHash);
```

### MsgExecuteContractCompat

在前面的示例中，使用 EIP712 解析 `funds` 数组和 `msgs` 对象存在一些兼容性问题。由于 `MsgExecuteContract` 无法正确转换为 EIP712 然后由以太坊钱包签名，我们引入了完全兼容 EIP712 的 `MsgExecuteContractCompat`。

***注意：*** *`MsgExecuteContract` 和 `MsgExecuteContractCompat` 的底层消息是相同的。`MsgExecuteContractCompat` 只是兼容 EIP712。*

以下是使用 `test` 合约函数发送 `MsgExecuteContractCompact` 的示例。

```ts theme={null}
import { Network } from "@injectivelabs/networks";
import { toChainFormat } from "@injectivelabs/utils";
import { MsgBroadcasterWithPk } from "@injectivelabs/sdk-ts/core/tx";
import { MsgExecuteContractCompat } from "@injectivelabs/sdk-ts/core/modules";

const injectiveAddress = "inj1...";
const contractAddress = "cw...";

const msg = MsgExecuteContractCompat.fromJSON({
  contractAddress,
  sender: injectiveAddress,
  exec: {
    action: "test",
    funds: [
      {
        denom: "inj",
        amount: toChainFormat(1).toFixed(),
      },
    ],
  },
});

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

console.log(txHash);
```
