Learn Stellar Smart Contracts and Soroban SDK The idea is to take good steps forward after doing the increment, log, error examples, and using Okashi.dev We’ll use Soroban version 22.0 which is new and improved ✅ Day 1: Minting a Token Objective: Learn how to create a smart contract for minting and managing a token. […]
This article helps understand the use of “tokens” in the world of blockchain. I’ll cover the the ability to mint, transfer, and burn tokens securely. What what happens when you want to ensure that a user’s transfer includes a “burn” action, to remove tokens from one address before transferring them to another? Let’s break it […]
We will come back to the actual Rust (Soroban SDK) auction code – the lib.rs – but while I have it to hand let’s just cover how to deploy, invoke AND make a bid on this toy auction smart contract. The key thing to know, is that you need to fund your bidder account (aka […]
Rather than get too specialized in Stellar’s syntax and proprietary code, the ongoing theme here is to learn as much about Smart Contracts as possible AND also improve our Rust programming/problem solving skills. Learn the concepts rather than the nitty gritty syntax which may change right? Futhermore, we’ll get plenty more practice with enums, public, […]
Smart contract in Rust – Stellar’s BytesN Example code demo using BytesN If you’re used to using symbol_short! macro, note how for more than 9 characters we need to use Symbol::new We’ll use a fixed length 32 bytes array here so we need BytesN in Stellar : You could also use base64 encoded :
Beyond the beginner friendly Soroban basics? Let’s now look at a larger Smart Contract example. As usual we’ll get to the essence of the code. We’ll stick to Alice and Bob for familiarity. What are we trying to achieve? The TimeLockContract is a Soroban smart contract designed to manage delayed execution of operations in a […]
This article explains how to use one of the Soroban provided examples We’ll Deploy and Invoke Soroban Smart Contracts where one contract calls another. TL;DR: Contract B’s add_with function invokes Contract A’s add function to do some addition. **Ok, so I used chatGPT to help write this, but the code has been tested by a […]
