A Complete Guide to Directly Operating Ethereum Smart Contracts with a Blockchain Explorer
How to Interact Directly with Ethereum Smart Contracts via Blockchain Explorer
This article will introduce a method that allows direct interaction with smart contracts through the Ethereum blockchain explorer without relying on any decentralized applications (DApp). This approach is not only safe and reliable but also enables users to better understand the operational mechanisms of smart contracts.
Preparation Work
Before we begin, please ensure you have the following tools ready:
Operation Steps
1. Ensure the network connection is normal.
First, make sure your network connection tools are working properly. When you can smoothly access websites like Google, it means the network connection is ready.
2. Target smart contracts
Open the Ethereum blockchain explorer and find the smart contract address you want to interact with. This tutorial uses a certain version of the QP Token deposit contract as an example to demonstrate how to retrieve QP Token.
3. Connect Web3 Wallet
In the blockchain explorer, click on 【Contracts】, then 【Write Contract】, and select 【Connect to Web3】 to connect your MetaMask wallet extension.
4. Find the target method
Scroll down in the contract interface until you find the method you need to call. In this example, we will use the【takeOut】method to retrieve the tokens.
5. Interact with the contract
Now, you need to fill in some parameters to execute the smart contracts method:
First input box: Enter the amount of tokens you want to withdraw. Note that you need to consider the decimal places of the tokens. For example, if you want to withdraw 100 tokens and the token has 18 decimal places, you need to enter: 100000000000000000000.
Second input box: Enter the contract address of the token you want to withdraw. Different tokens have different contract addresses, please ensure the input is correct.
After filling in the parameters, click the 【Write】 button to initiate the transaction. You can check the processing progress of the transaction through 【View your transaction】.
Summary
By following the steps above, you can interact directly with smart contracts on the blockchain explorer without the need to use any third-party DApp or import your private key into unfamiliar software. This method is not only safe and reliable but also helps you gain a deeper understanding of how smart contracts work.
Please note that before performing any operations, it is crucial to carefully verify the contract address and parameters to ensure the security and accuracy of the transaction. Additionally, it is recommended to test with a small amount before handling large transactions to familiarize yourself with the entire process and ensure everything is functioning correctly.
