A tutorial on interacting directly with Ethereum smart contracts through Etherscan

A Simple Guide to Direct Interaction with Ethereum Smart Contracts

This article will introduce how to interact directly with Ethereum smart contracts through the Etherscan block explorer without relying on any DAPP.

Preparation Work

  • Network Proxy Tool
  • MetaMask browser extension

Operation Steps

  1. Ensure that you can access the Google search engine normally, indicating that the network proxy settings are successful.

  2. Open the Etherscan block explorer and find the target smart contracts 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.

  1. On the contract page, click the "Contract" tab, then select "Write Contract". Click the "Connect to Web3" button to connect the MetaMask wallet extension.

  1. In the contract interaction interface, scroll to the "takeOut" method.

  1. Interact with the contract:

    a) In the first input box, enter the quantity of QP Tokens to withdraw. For example, to withdraw 100 tokens, you need to enter: 100000000000000000000 (100 followed by 18 zeros).

    b) In the second input box, enter the token contract address of the QP Token you want to withdraw. For example:

    • NEST Token: 0x04abeda201850ac0124161f037efd70c74ddc74c
    • NYFI: 0x075190c6130ea0a3a7e40802f1d77f4ea8f38fe2
    • NHBTC: 0x1f832091faf289ed4f50fe7418cfbd2611225d46

    c) Click the "Write" button to initiate the transaction.

d) Click "View your transaction" to check the transaction status and wait for the transaction confirmation to complete.

By this method, we can safely interact with smart contracts without using unknown DAPPs or importing wallets into unfamiliar software. This direct operation through the block explorer provides users with higher security and control.

It is important to note that before engaging in any contract interactions, you should fully understand the implications of the operation and the potential risks involved. If you have any questions, it is advisable to consult a professional or conduct in-depth research on the relevant documentation.

I really admire that there are people who still manually write contract interactions.
