A Simple Tutorial for Direct Interaction with Ethereum Smart Contracts

This article will introduce how to interact directly with Ethereum smart contracts through the Etherscan block explorer without relying on any DAPP. This method is both secure and convenient, allowing you to complete the required transaction operations without importing your wallet into unfamiliar software.

Preparations

Before we begin, please ensure you have the following tools ready:

• Reliable network environment
• MetaMask wallet extension

Operation Steps

1. Ensure that your network environment is stable and can normally access websites like Google.

2. Open the Etherscan block explorer and find the target smart contracts address. This tutorial takes the NEST 3.0 version of the QP Token deposit contract as an example to demonstrate how to retrieve QP Token.

3. On the contract page, click "Contract", then "Write Contract", and then select "Connect to Web3" to connect your MetaMask wallet.

4. Find the "takeOut" method in the contract method list.

5. Interact with the target smart contracts:

   • In the first input box, enter the amount of QP Token to be withdrawn. For example, to withdraw 100 tokens, enter: 100000000000000000000 (add 18 zeros after 100).
   • In the second input box, enter the contract address of the QP Token to be withdrawn. The contract addresses for different tokens vary, so please ensure you use the correct address.

6. Click the "Write" button to initiate the transaction. You can then click "View your transaction" to check the transaction progress and wait for the transaction to be confirmed.

Notes

• When entering the Token amount, please pay attention to add the correct decimal places.
• Make sure to use the correct token contract address to avoid mistakes.
• After the transaction is initiated, please patiently wait for the block confirmation and do not perform repeated operations.

By this method, you can securely interact with Ethereum smart contracts without relying on third-party DAPPs or importing your wallet into unknown software. This not only enhances the security of the operation but also simplifies the interaction process. I hope this tutorial helps you better manage your digital assets.
