Integrating Metamask with AnySwap Router: A Step-by-Step Guide

As a token router developer, integrating your own router with anyswap.com is crucial for seamless user experience. In this article, we will guide you through the process of creating a custom token router that integrates seamlessly with the anyswap.com bridge.

Prerequisites

Before starting, make sure you have:

A MetaMask wallet

The anyswap.com API key (obtainable from [here](

The ABI (Application Binary Interface) of your custom token router contract

Step 1: Set up Metamask and AnySwap Account

Install MetaMask on your desktop or mobile device.

Create a new account in anyswap.com and replace the default API key with your own API key.

Step 2: Choose your Blockchain

Anyswap supports multiple blockchains, including Ethereum (mainnet), Binance Smart Chain, Binance OnChain, and others. For this example, we will use Ethereum (mainnet).

Step 3: Create a MetaMask Wallet

Open the MetaMask browser extension or app.

Create a new wallet by clicking on “New Wallet” in the top right corner.

Step 4: Set up your Custom Token Router Contract

Create a new contract on anyswap.com using the “Contract” button in the Bridge tab. Choose Ethereum (mainnet) and the blockchain.

Copy and paste the ABI of your custom token router contract into the contract code field.

Set up the contract functions according to your requirements (e.g., createToken, transferToken).

Step 5: Configure MetaMask to Use Your Custom Token Router

In MetaMask, go to “Settings” > “Account” and add a new account for your custom token router contract.

Set the default network as Ethereum (mainnet).

Update the wallet’s provider to point to your own wallet.

Step 6: Integrate with AnySwap Router

In your MetaMask instance, navigate to the Bridge tab.

Click on “Anyswap” in the left-hand menu.

Select your custom token router contract from the list of available contracts.

Now you can call your custom token router functions using anyswap.com’s API endpoints!

Sample Code

Here is an example of how you could use Metamask to call a simple createToken function:


const metamask = require("metamask");


// Set up MetaMask wallet

metamask.start();


// Get the contract instance from aniswap.com

const contractInstance = await metamask.getContractInstance({

  contractAddress: "0x...YOUR_CONTRACT_ADDRESS...",

});


// Call a function on your custom token router contract

async function createToken() {

  try {

    const response = await contractInstance.createToken("Your Token Name", 10);

    console.log(response);

  } catch ( error ) {

    console.error(error);

  }

}


createToken();

This is just a basic example to get you started. You can implement more complex logic and functionality as needed.

Conclusion

Integrating Metamask with anyswap.com is a straightforward process that allows you to create your own token router. By following these steps, you can set up your custom contract and call functions on your token router using the aniswap.com API endpoints. Happy coding!
