Deploy and Interact with Wrapped Token

Learn how to deploy and interact with wrapped tokens

In this section, we will deploy and interact with a wrapped token using Forge and cast commands. Forge simplifies smart contract deployment, and cast allows you to interact with deployed contracts.

1. Write the Wrapped Token Contract

Here is a basic implementation of a wrapped token contract in Solidity:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
 
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
 
contract WrappedToken is ERC20 {
    address public nativeTokenHolder;
 
    constructor() ERC20("Wrapped Token", "WTKN") {}
 
    function deposit() external payable {
        _mint(msg.sender, msg.value);
        nativeTokenHolder = msg.sender;
    }
 
    function withdraw(uint256 amount) external {
        _burn(msg.sender, amount);
        payable(msg.sender).transfer(amount);
    }
}

Deploy ERC20 Receiver

Deploy the Contract Using Forge's create Command

forge create --rpc-url myblockchain --private-key $PK WrappedToken.sol:WrappedToken

Save the Wrapped Token Address

Save the Deployed to address in an environment variable.

export WRAPPED_TOKEN=<address>

Interacting with the Deployed Contract

Once the contract is deployed, you can interact with it using cast commands.
