Ethereum contract operation process operation
Jul 15, 2025 pm 08:54 PMThe Ethereum smart contract operation process includes six main steps: 1. The development preparation stage requires the installation of Node.js, Solidity compiler, configuration of the development environment and preparation of storage; 2. The contract writing and compilation requires the use of the Solidity language to define the structure and generate bytecode and ABI; 3. The deployment of the contract requires connection to the network, creation of transactions, and signature to obtain the deployment address; 4. The contract interaction is divided into read (call) and write (sendTransaction) operations; 5. Monitoring and event processing involves listening to events and querying transaction status; 6. Security considerations include testing logical vulnerabilities, setting gas parameters, permission control and using security libraries.

Detailed explanation of the operation process of Ethereum smart contract
1. Development preparation phase
Before operating an Ethereum smart contract, developers need to complete the following preparations:
Install Node.js and npm/yarn package manager
Install Solidity compiler (solc) or use Remix online IDE
Configure development environments (such as Truffle, Hardhat, or Foundry frameworks)
Prepare Ethereum storage (MetaMask, etc.) and obtain testnet ETH
2. Contract writing and translation
Operation process:
Writing smart contract code (.sol file) using Solidity language
Define contract structures, state variables, functions, and events
Compile Solidity code into EVM bytecode and ABI interface via compiler
// Example: simple storage contract pragma solidity ^0.8.0;contract SimpleStorage { uint storedData; function set(uint x) public { storedData = x; } function get() public view returns (uint) { return storedData; }}
3. Deploy the contract
Operation steps:
Connect to the Ethereum network (main network or test network)
Interact with blockchain using Web3.js or Ethers.js library
-
Create a contract to deploy transactions, including:
Compiled bytecode
Constructor parameters (if any)
Specified gas limit and gas price
Signing transactions with storage private key
Broadcast transactions to the network and wait for miners to pack
Get the contract deployment address (contractAddress in transaction receipt)
4. Contract interaction
Main operation methods:
Read operation (call): free query of contract status
const value = await contract.methods.get().call()
Write operation (sendTransaction): Gas fee needs to be paid to modify the status
await contract.methods.set(123).send({from: account})
5. Monitoring and event handling
Listen to contract events:
contract.events.EventName({ filter: {key: value}, fromBlock: 'latest'}, (error, event) => console.log(event))
Query transaction status:
const receipt = await web3.eth.getTransactionReceipt(txHash)
6. Safety precautions
Strictly test contract logic to avoid loopholes such as reentry
Set gas limits and gas prices reasonably
Add permission control for important operations
Consider using security libraries like OpenZeppelin
The complete operation process involves multiple links of development, testing, deployment and interaction, and each step needs to be handled with caution to ensure the contract runs safely and reliably.

The latest news on September 18th, Huawei HarmonyOS6 has launched multiple rounds of preview version push for developers, and has recently opened the experience qualification to some users who have tried it out for the first time. According to user feedback, the current system name no longer displays the "NEXT" suffix, and it is officially renamed to HarmonyOS6.0. Huawei initially proposed the name HarmonyOSNEXT for the first time at the developer conference in August 2023, aiming to mark the Hongmeng system entering a new stage of development and realizing true native self-development. HarmonyOSNEXT's most core breakthrough is to completely adopt the underlying system architecture developed independently, completely remove the Linux kernel and Android AOSP code, and only run applications based on the HarmonyOS kernel.

On September 17, the iPhone 17 series review was officially lifted, and the Huangjia Review immediately released the first launch experience of the series. This time, the iPhone 17 has launched four models, namely iPhone 17, iPhone 17 Pro, iPhone 17 ProMax and the newly unveiled iPhone Air. Among them, the standard version of iPhone 17 has undergone a significant upgrade, and is equipped with a high-end screen that was previously only available in the Pro series for the first time. The new phone is equipped with a 6.3-inch ProMotion adaptive high refresh rate screen, with a peak brightness of up to 3,000 nits, and a second-generation anti-reflective super-ceramic crystal glass panel. The core display parameters have been fully matched with the iPhone 17P.

In the just-concluded Peace Elite Professional League (PEL) Summer Finals, OnePlus' new flagship model OnePlus 15 made its official debut and was officially announced to be the designated machine for the official competition of the new generation of PEL. Judging from the actual photos exposed on the spot, OnePlus 15 adopts a new rounded matrix array image module design, and the overall style is quite similar to the previously released OnePlus 13T, and it is more concise and neat visually. It is worth noting that the machine no longer continues to cooperate with Hasselblad’s imaging, but instead is equipped with OPPO’s self-developed OPPOLUMO light condensing imaging system, marking a brand’s new exploration in the imaging technology path. In terms of screen configuration, OnePlus 15 will launch a 1.5K resolution, 165Hz high refresh rate display jointly developed with BOE in the world. official

Windows 10 system comes with automatic maintenance function, which can perform maintenance tasks on the system according to the set time, such as system updates or disk defragmentation. By default, Windows 10 automatic maintenance is enabled. However, in some cases, we may prefer to manage these maintenance operations on our own to better control the equipment. So, how can I turn off the automatic maintenance service of Windows 10? Next, let’s take a look at the specific steps together, I hope it will be helpful to everyone. The specific method for disabling the automatic maintenance function in Win10 is as follows: Step 1, press the Win and R keys at the same time to open the running window. After entering regedit, click OK or press Enter; step 2: If the user account control is added

Everyone knows that there are many types of blue screen phenomena in Windows 10. When blue screen occurs, many people often don’t know how to deal with it. Since most of the code displayed on the blue screen is obscure and difficult to understand, many users are confused and difficult to solve the problem on their own. Today, let’s talk about how to effectively deal with Kernel_Security_check_Failure blue screen code. This blue screen code usually indicates that there are problems with the driver, and the most common errors are network cards and graphics drivers. The reasons for the KERNEL-SECURITY-CHECK-FAILURE blue screen may be as follows: There are compatibility issues with network card drivers. The graphics card driver version does not match or is damaged. In response to this situation,
