cw-optimizoor

A blazingly fast alternative to CosmWasm/rust-optimizer for compiling & optimizing CW smart contracts.

It's primarily meant to speed up local development and testing.

Features:

• Fast - especially in workspaces with many contracts
• Uses same optimizations as rust-optimizer by default
• No dependency on Docker
• Supports both single- & multi-contract workspaces
• Written as a cargo subcommand
• Cross-platform, cross-arch

Installation

# Pre-requisites
