# Wallet Integration

## Overview <a href="#overview" id="overview"></a>

Ramper supports many standardized methods, including: `signMessage` , `signTransaction` , `sendTransaction` , `sendToken`

## Example <a href="#example" id="example"></a>

```javascript
import {
  sendToken,
  sendTransaction,
  signMessage,
  signTransaction,
} from "@ramper-v2/multi";
import { CHAIN } from "@ramper-v2/core";
 
...
 
// Initialize Chain
const chain = CHAIN.VICION;
 
// Sign Message
const handleSignMessage = async () => {
  const result = await signMessage({
    message: abc,
    chain,
  });
};
 
// Sign Transaction
const handleSignTransaction = async () => {
  // Please use your own nonce and estimateGas function
  const nonce = await getNonce(publicKey);
  const gasLimit = await estimateGas({
    to: receiver,
    value: //,
  });
 
  const transaction = {
    from: publicKey,
    data: "0x",
    gasLimit: gasLimit.toString(),
    nonce,
    to: receiver,
    value: amount,
  };
  const result = await signTransaction({
    transaction,
    chain,
  });
};
 
// Send Transaction
const handleSendTransaction = async () => {
  // Please use your own nonce and estimateGas function
  const nonce = await getNonce(publicKey);
  const gasLimit = await estimateGas({
    to: receiver,
    value: amount,
  });
 
  const transaction = {
    from: publicKey,
    data: "0x",
    gasLimit: gasLimit.toString(),
    nonce,
    to: receiver,
    value: amount,
  };
  const result = await sendTransaction({
    transaction,
    chain,
  });
};
 
// Send Token
const handleSendToken = async () => {
  const result = await sendToken({
    transaction: {
      from: publicKey,
      to: receiver,
      value: amount,
    },
    symbol: "c98",
    chain,
  });
};
```
