Solana wallet with Rust: get started now
In this tutorial, we will learn the basics of Solana development by programming a software wallet with Rust. What is a cryptocurrency wallet? A cryptocurrency wallet’s primary function is storing keys that allow you to send and receive cryptocurrency, in this case, Solana. This wallet can be a device or software program. For this tutorial, we will write a Solana wallet with Rust that can generate keys and perform actions. With our wallet application, we will be able to: All this using Rust code. To help us easily connect to Solana RCP servers we will use Solana crates like: solana_client…

Rust SQLx basics with SQLite: super easy how to
In this tutorial, we will learn the basics of using the SQLx crate with Rust and SQLite. The SQLx crate is an async pure Rust SQL crate featuring compiling time-checked queries. However, it is not an ORM. We will look at how to create an SQLite database and do SQL operations on it with SQLx. After we complete this tutorial we will have a good understanding of the basics for using SQLite databases in our future Rust projects using SQLx. The repository with the finished project can be found here: https://github.com/tmsdev82/sqlx-sqlite-basics-tutorial. Another rust and database-related article can be found here:…
Solana transactions per second: how to with Rust
In this tutorial, we will learn how to count Solana transactions per second (TPS) using the Rust programming language. We will look at how to connect to the Solana blockchain API using the Solana SDK crates. Using this simple program we will learn some basics about using the Solana crates for Rust. Our program will count non-vote transactions over the course of some time period and then calculate the transactions per second.
