A simple tutorial for interacting directly with Ethereum smart contracts

This article will introduce you to how to interact directly with Ethereum smart contracts through Etherscan without relying on any DAPPs. This method is both secure and convenient, suitable for those who wish to avoid using unfamiliar software.

Preparation

Before we begin, please ensure that you have:

1. Install a reliable network acceleration tool
2. Installed the MetaMask browser extension

Steps

1. Ensure that the network connection is normal.

First, launch your network acceleration tool. When you are able to access Google without any problems, the network connection is ready.

2. Find the target smart contract

Open the Etherscan block explorer and find the smart contract address you want to interact with. This tutorial takes the NEST 3.0 version of the QP Token deposit contract as an example to demonstrate how to retrieve QP Token.

4. Target positioning method

Find the method you need to call in the contract interface. In this example, we will use the "takeOut" method to retrieve the QP Token.

5. Execute contract interaction

For example, to withdraw 100 NEST Tokens:

1. In the first input box, enter the number of tokens (including 18 decimal places) to be withdrawn: 100000000000000000000

2. In the second input box, enter the contract address of the Token: For NEST Token: 0x04abeda201850ac0124161f037efd70c74ddc74c For NYFI: 0x075190c6130ea0a3a7e40802f1d77f4ea8f38fe2 For NHBTC: 0x1f832091faf289ed4f50fe7418cfbd2611225d46

3. Click the "Write" button to initiate the transaction.

4. Click "View your transaction" to check the transaction status.

5. Wait for the transaction to be confirmed

In this way, you can securely interact with smart contracts without using any additional DAPPs or importing your wallet into unknown software. This not only increases the safety of the operation, but also simplifies the entire process. This is an ideal option for those who want direct control over their assets.

Please remember to carefully verify all input information when conducting any blockchain transactions to ensure the accuracy and security of the operations. If you are unsure about certain steps, it is advisable to try them on a test network first or seek assistance from professionals.
