Metamask: How to send a specific token from a wallet when there are multiple tokens

Sending Specific Tokens from MetaMask: A Step-by-Step Guide

MetaMask is a popular cryptocurrency wallet that allows users to interact with the Ethereum blockchain. In this article, we will show you how to programmatically send specific tokens from your MetaMask wallet to another wallet.

Prerequisites

You have MetaMask wallet installed on your computer or mobile device.

You have two ERC20 tokens in your MetaMask wallet, for example TOKEN_1 and TOKEN_2.

The recipient wallet has the necessary permissions to receive tokens.

Step 1: Get the token addresses

To send specific tokens from your MetaMask wallet, you need to get their addresses. Here’s how to do it:

Open MetaMask on your computer or mobile device.

Go to the “Wallets” > “Exchange” tab and click the “Token List” button.

In the list of available tokens, find the two ERC20 tokens you want to send.

Click on the address of each token in the list. A new tab will open with the token details, including the contract address.

Step 2: Send tokens using RPC

To programmatically send specific tokens from your Metamask wallet to another wallet, you need to use Web3’s RPC (Remote Procedure Call) functionality. Here’s how to do it:

Make sure you have the MetaMask extension installed on your browser.

Return to the MetaMask “Token List” tab and select the two tokens you want to send.

Click the “Send” button next to each token. A new window will open with the recipient’s wallet details.

3. Step 4: Enter recipient wallet information

In the “Send” window, enter the following information about the recipient wallet:

Contract address

Private key (or account address)

Gas limit (optional)

Step 4: Confirm token transfer

Once you have entered the required information, click the “Confirm” button to send the tokens.

Code example

Here is an example JavaScript code snippet that shows how to send specific tokens from your Metamask wallet to another wallet:


const MetaMask = request('metamask');
// Replace with your private key and contract address
const privateKey = '0x...';
const recipientContractAddress = '0x...';
const metaMask = new MetaMask({
extension: true,
accounts: [privateKey],
});
metaMask.on('connect', () => {
const tokenAddresses = ['0x...', '0x...'];
tokenAddresses.forEach((tokenAddress) => {
// Send TOKEN_1 to the recipient wallet
metaMask.send({ to: recipientContractAddress, tokens: [tokenAddress] });
});
});
metaMask.on('connect', () => {
const tokenAddresses = ['0x...', '0x...'];
tokenAddresses.forEach((tokenAddress) => {
// Send TOKEN_2 to the recipient wallet
metaMask.send({ to: recipientContractAddress, tokens: [tokenAddress] });
});
});

This code snippet shows how to send specific tokens from your Metamask wallet to another wallet using RPC. You will need to replace “privateKey” and “recipientContractAddress” with your private key and contract address.

Conclusion

Sending specific tokens from MetaMask is a simple process that requires minimal setup. By following the steps outlined in this article, you can easily send ERC20 tokens between wallets programmatically using Web3 RPC functionality. Happy coding!
