Ethereum smart contracts interaction guide: No DAPP required, just use Etherscan

This article will provide you with a detailed introduction on how to directly interact with Ethereum smart contracts through the Etherscan block explorer, without relying on any DAPP applications. This method is both secure and convenient, especially suitable for users who wish to avoid using unfamiliar software.

Preparation Work

Before we begin, please ensure that you have:

1. Installed a reliable network proxy tool
2. Installed the MetaMask browser extension

Steps to Operate

1. Ensure that the network connection is normal.

First, start your network proxy tool. When you can access Google search normally, it indicates that the network connection is ready.

2. Access the target smart contracts

Open the Etherscan block explorer and find the smart contract 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 execute the "retrieve" QP Token operation.

3. Connect Wallet

On the contract page, click "Contracts" and then "Write Contract" in sequence, and then select the "Connect to Web3" option. In the pop-up window, choose and connect your MetaMask wallet.

4. Target positioning method

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

5. Execute contract interaction

After finding the target method, you need to fill in the following information:

• First input box: Enter the amount of QP Token you wish to withdraw. Please note that you need to consider the decimal places of the token when entering. For example, if you want to withdraw 100 tokens, the actual input should be: 100000000000000000000 (100 followed by 18 zeros).

• Second input box: Enter the contract address of the QP Token you want to withdraw. The contract addresses for different tokens are different, so please ensure you use the correct address.

After filling out, click the "Write" button to initiate the transaction. You can check the transaction progress through the "View your transaction" option and wait for the transaction to be confirmed.

Conclusion

By this method, we can directly interact with the smart contracts on Etherscan without using any third-party DAPPs or importing wallets into unknown software. This not only enhances the security of the operation but also provides users with a more direct and transparent way to interact.

Please remember to carefully verify all information before performing any blockchain operations to ensure the security and accuracy of the transactions.
