Compile messaging contract

Before a contract can be used, it must be compiled into wasm bytecode or artefacts that can be stored on chain.

CUDOS Blast makes compilation easy with a single command.

01 Modify files​

  1. Open contracts > schema.rs and replace alpha with your project-name.

update-schema

  1. Open src > cargo.toml and replace alpha with your project-name

update-cargo

02 Compile your contract​

  1. Make sure you have docker running.

  2. Run the following command:

    blast compile
    # Example
    blast compile
