# Kadena dApp Integration

CLV extension wallet will inject clover\_kadena to window object, dApp could use it to integrate with CLV extension wallet.

```
window.clover_kadena = {
  isCloverWallet: true,
  getAccount: async ()=> {...},
  sign: async (paload) => {...}
}
```

## Sample Code

Below is an example for dApp to integrate CLV extension wallet

```
signKdaTransaction = async () => {
    if (!window.clover_kadena) {
      this.console('wallet not injected!')
    }

    var mkReq = function(cmd) {
      return {
        headers: {
          "Content-Type": "application/json"
        },
        method: "POST",
        body: JSON.stringify(cmd)
      };
    };

    try {
      const account = await window.clover_kadena.getAccount()
      await new Promise((resolve) => setTimeout(resolve, 3000))
      const signCmd = {
        pactCode: `(free.hello-world.set-message ${JSON.stringify('hello test')})`,
        caps: [
          Pact.lang.mkCap("Gas capability", "description of gas cap", "coin.GAS", []).cap,
        ],
        sender: account,
        gasLimit: 10000,
        chainId: "0",
        ttl: 28800,
        envData: {}
      }

      const result = await window.clover_kadena.sign(signCmd)
      const txRes = await fetch(`https://api.testnet.chainweb.com/chainweb/0.0/testnet04/chain/0/pact/api/v1/send`, mkReq(result));
      const tx = await txRes.json();
    } catch (e) {
      console.log(e)
    }
  }
```
