How to Interact Directly with Smart Contracts Using the Ethereum Blockchain Explorer

This article will introduce a method that does not rely on any decentralized applications (DAPPs) and teach you how to interact directly with smart contracts through the Ethereum blockchain explorer Etherscan. This method is simple and secure, suitable for various Ethereum smart contract operations.

Preparation Work

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

1. Reliable network connection tool
2. MetaMask wallet browser extension

Steps to Operate

1. Ensure the network connection is normal.

First, please ensure that your network connection tool is functioning properly. A simple test method is to try searching for content on Google; if it works normally, it indicates that the network connection is successful.

2. Find the target smart contracts

Open the Etherscan blockchain explorer and find the smart contracts address you want to interact with. This tutorial uses the NEST 3.0 version of the QP Token deposit contract as an example to demonstrate how to perform the QP Token retrieval operation.

3. Connect Web3 wallet

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

4. Targeting method

Scroll down on the contract page to find the method you need to use. In this case, we need to find the "takeOut" method.

5. Interact with smart contracts

After finding the target method, fill out the necessary information according to the following steps:

a) In the first input box, enter the amount of QP Token you want to withdraw. Note that you need to add 18 zeros after the amount. For example, to withdraw 100 tokens, you should enter: 100000000000000000000.

b) In the second input box, enter the token contract address of the QP Token you want to withdraw. For example:

• NEST Token: 0x04abeda201850ac0124161f037efd70c74ddc74c
• NYFI: 0x075190c6130ea0a3a7e40802f1d77f4ea8f38fe2
• NHBTC: 0x1f832091faf289ed4f50fe7418cfbd2611225d46

c) Click the "Write" button to initiate the transaction.

d) Click "View your transaction" to check the transaction progress and wait for the transaction to complete.

By following the steps above, you can interact directly with the smart contracts through the Etherscan blockchain explorer, without the need to use any additional DAPPs or import your wallet into unfamiliar software. This method is not only simple and direct but also ensures the security of your assets.

Please remember to carefully verify all information when performing any blockchain operations to ensure the operations are correct. If you are unsure about certain steps, it is recommended to try them first on a test network or seek assistance from professionals.
