Getting started​

:::warning 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
