Multi-chain support is not as simple as you think

Sat, 05 Jul 2025 08:20:55 +0000

A practical reflection on multi-chain wallet integration

Finally, I have some free time to sort out the code. The Web3 project has access to multi-chain wallet connection functions, mainly involving Ethereum, Polygon, BSC and Solana. At first glance, it seemed like it was just a matter of “doing a few more sets of compatible logic”, but after I actually implemented it, I discovered that many things were actually not as simple as I thought.

What is Web3.0, and what does it have to do with blockchain?

Mon, 17 Jun 2024 12:59:22 +0000

Another new inexplicable word -. - I can roughly summarize it into the following points:

What is web3.0

Web 3.0 (Web3) is the development direction of the next generation of the Internet, aiming to create a more decentralized, user-controlled and data-protected network environment. Different from the previous Web 1.0 (static web pages) and Web 2.0 (dynamic, interactive web pages and social media), the core concepts and technologies of Web 3.0 include the following aspects:

Thermal Bluetooth printer development

Tue, 05 Nov 2019 14:49:50 +0000

Recently, I have been working on receipt printing. The project requirement is to implement it on both IOS and Android. I was confused when I started doing it. Then I found a lot of information on the Internet, stepped on a lot of pitfalls, and read a lot of articles. The result turned out to be okay. Bluetooth printers are generally divided into two printing modes, receipt printing and label printing.

WeChat authorized login

Fri, 05 Apr 2019 09:29:45 +0000

Documentation: https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421135319

The authorized login of WeChat is similar to the authorized login of QQ, Sina and other platforms, and both adopt the OauthOAuth2.0 authentication method.
There are two types of WeChat authorization:

Silent authorization
Pop-up authorization requires manual consent from the user.

Explanation of the differences between the two scopes

WeChat JSAPI payment

Sat, 30 Mar 2019 09:30:21 +0000

I have been doing business related to WeChat some time ago. Although it is not a new technology, I have never had the opportunity to come into contact with it before. Then I stepped on some pitfalls and took the time to organize and record it.
There are 7 types of WeChat payment, including: payment code payment, JSAPI payment, Native payment, APP payment, H5 payment, mini program payment, and face payment.
WeChat JSAPI payment is used in this business: the user enters the merchant’s H5 page by scanning the QR code on WeChat, following the official account, etc., and calls JSSDK within WeChat to complete the payment.

Simple Steps for Using Git

This article does not elaborate any conceptual knowledge, just make a note, simply is the use of the steps, if you encounter obstacles, please Google it!

Using SSH to Bind Git to GitHub

1. Generate SSH key

ssh-keygen -t rsa

Specify the RSA algorithm to generate the key, after which two files will be generated, id_rsa and id_rsa.pub, i.e., the key id_rsa and the public key id_rsa.pub. For these two files

Use .htaccess to bind subdomain names to subdirectories

Mon, 22 Jan 2018 01:18:11 +0000

Under normal circumstances, a virtual host is only allowed to bind one domain name to the root directory.
People who have used emlog should be familiar with the static links in it. It is a typical use of .htaccess files to redirect domain names to web pages.
Use .htaccess to bind domain names to subdirectories. The prerequisite is that your space server must support the rewrite function of apache. Only in this way can .htaccess be used. If your space is a Linux server, it is usually enabled by default. That is, you can bind domain names to subdirectories and multiple sites in one space.
