Interact with smart contracts directly on Etherscan: A secure and convenient operation guide
A Simple Way to Interact with Ethereum Smart Contracts
This article will introduce a method to interact directly with Ethereum smart contracts without relying on any decentralized application (DAPP), using only Etherscan. This method is simple and effective in protecting user security.
First, users need to prepare a scientific internet access tool and the MetaMask wallet plugin. Once they can access the Google search engine, they can begin operations.
Next, open the Etherscan block explorer and find the target smart contracts address. This article takes the deposit contract of the NEST 3.0 version QP Token as an example to demonstrate how to retrieve QP Token.
On the contract page, click the "Contract" tab, then select "Write Contract". Click the "Connect to Web3" button to connect the MetaMask wallet extension.
Scroll down the page to find the target method. In this case, we need to use the "takeOut" method.
When interacting with the target contract, the following information needs to be filled in:
Enter the amount of QP Token to be withdrawn. For example, to withdraw 100 tokens, you need to input 100 followed by 18 zeros: 100000000000000000000. If you want to withdraw 10000 tokens, you would enter 10000000000000000000000.
Enter the token contract address of the QP Token to be withdrawn. For example:
After filling out, click the "Write" button to initiate the contract interaction transaction. Then you can click "View your transaction" to check the transaction packaging status and wait for the transaction to succeed.
By this method, users can interact directly with smart contracts through the Etherscan block explorer to complete the required transaction operations without using any DAPP or importing their wallet into unfamiliar software. This not only simplifies the operation process but also enhances security, making it a recommended way to interact with Ethereum smart contracts.
