Ethereum blockchain explorer direct interaction smart contracts tutorial
How to Interact Directly with Smart Contracts via the Ethereum Blockchain Explorer
This article will introduce a method to interact directly with smart contracts without relying on any DAPP, using only the Ethereum blockchain explorer. This approach is safe and reliable, suitable for users who wish to avoid using unfamiliar software.
Preparation Work
Before you begin, please ensure you have the following tools ready:
Operation Steps
First, enable scientific internet access to ensure you can normally access the Google search engine.
Open the Ethereum blockchain explorer and find the target smart contract 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.
Click the "Connect to Web3" button to connect your MetaMask wallet.
Scroll down the page to find the target method, which in this case is the "takeOut" method.
Interact with the target smart contracts:
In the first input box, enter the quantity of QP Tokens to withdraw. For example, to withdraw 100 tokens, enter: 100000000000000000000 (add 18 zeros after 100).
In the second input box, enter the token contract address of the QP Token to be withdrawn. For example:
Click the "Write" button to initiate the contract interaction transaction.
Click "View your transaction" to check the transaction status and wait for the transaction to be confirmed.
By this method, we can directly interact with smart contracts on the Ethereum blockchain explorer without the need to use any additional DAPPs or import wallets into unfamiliar software. This not only simplifies the operational process but also enhances security, making it a practical skill worth mastering.
