Beginner's Tutorial: Directly Interacting with Ethereum Smart Contracts on Etherscan
How to Interact Directly with Ethereum Smart Contracts via Blockchain Explorer
In this tutorial, we will introduce how to directly interact with smart contracts using the Ethereum blockchain explorer Etherscan without relying on any decentralized applications (DApp). This method allows users to safely complete the necessary transaction operations without the need to import their wallets into unknown software.
Preparations
Before starting, please make sure that you have:
Step-by-step Explanation
1. Ensure the network connection is normal.
First, start your scientific internet access tool. When you can successfully access Google search, it indicates that the network connection is ready.
2. Find the target contract
Open the Etherscan blockchain explorer and find the smart contract address you want to interact with. In this example, we will use the NEST 3.0 version of the QP Token deposited in the contract to demonstrate how to perform the token retrieval operation.
3. Connect Web3 wallet
On the contract page, click "Contract", then "Write Contract", and select "Connect to Web3" to connect your MetaMask wallet extension.
4. Targeting Objective Function
Scroll down on the contract page to find the function you need to call. In this example, we will use the "takeOut" function to retrieve QP Token.
5. Execute contract interaction
Fill in the function parameters and initiate the transaction according to the following steps:
In the first input box, enter the amount of QP Tokens you wish to withdraw. For example, to withdraw 100 Tokens, you need to enter: 100000000000000000000 (100 followed by 18 zeros).
In the second input box, enter the token contract address of the QP Token you want to withdraw. For example:
Click the "Write" button to initiate the transaction.
By this method, you can safely interact with smart contracts without using any third-party DApps or importing wallets into unfamiliar software. This not only enhances the security of operations but also provides users with a more direct and transparent contract interaction experience.
Please note that when conducting any blockchain transactions, it is essential to carefully verify all input information to ensure that the transaction parameters are correct. Additionally, it is recommended to test with a small amount before making large transactions to ensure that the operation is correct.
