Getting started

Version compatibility

These tutorials reference specific versions of wasmd and CosmWasm:

• The tutorials use wasmd v0.53.2 with some code links referencing v0.52.0/v0.53.0
• Current documentation uses wasmd v0.52.0 as an example version
• Rust version 1.80.1 is used in the tutorials
• Some code references point to older versions of CosmWasm/wasmd

The core concepts remain valid, but you may need to adjust:

• Version numbers in git clone commands
• CLI command syntax (which has remained relatively stable)
• Some API references

For the most up-to-date installation and setup instructions, see:

• Wasmd Setup Guide
• Core Installation Guide

Start with the Introduction to understand the fundamentals, then follow the numbered sequence for the best learning experience.
