How to Interact Directly with Smart Contracts on the Ethereum Blockchain Explorer

This article will introduce a method to interact directly with smart contracts through the Ethereum blockchain explorer Etherscan, without relying on any decentralized application (DAPP). This approach is both secure and convenient, suitable for users who wish to avoid using unfamiliar software.

Preparation Work

Before starting, please ensure you have the following tools ready:

1. Scientific Internet Access Tool
2. MetaMask wallet browser extension

Operation Steps

1. Scientific Internet Access

First, make sure you can access the Google search engine normally, which indicates that your science-based internet access has been successfully enabled.

2. Access the target smart contracts

Open the Etherscan blockchain 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 retrieve QP Tokens.

3. Connect Web3 wallet

On the contract page, click "Contract" → "Write Contract" → "Connect to Web3" in sequence, and then connect your MetaMask wallet extension.

4. Target positioning method

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

5. Execute contract interaction

After filling in the necessary parameters, you can interact with the smart contracts. For example, to withdraw 100 QP Tokens:

• First input box: Enter the amount of tokens to withdraw, remember to add 18 zeros (100000000000000000000)
• Second input box: Enter the token contract address you want to withdraw

Finally, click the "Write" button to initiate the transaction, then click "View your transaction" to check the transaction status and wait for the transaction confirmation.

Notes

• When withdrawing different tokens, you need to fill in the corresponding token contract address. For example:
  • NEST Token: 0x04abeda201850ac0124161f037efd70c74ddc74c
  • NYFI: 0x075190c6130ea0a3a7e40802f1d77f4ea8f38fe2
  • NHBTC: 0x1f832091faf289ed4f50fe7418cfbd2611225d46

By this method, we can safely interact with Ethereum smart contracts without the need to use any third-party DAPP or import wallets into unfamiliar software. This not only enhances security but also provides users with a more direct operating experience.
