Release: mx-sdk-rs-v0.58.0

SpaceCraft SDK v0.58.0 is live, and testing just got a lot more real.

‍

This release was 3+ months in the making, with over 27,000 lines of code rewritten to open up testing workflows for real-world complexity.

‍

For the first time ever, you can run actual smart contracts in blackbox tests, no source code needed. That means better testing for contracts you don’t own, don’t control, or just don’t want to peek into.

Why this matters:

• Run tests against any Wasm contract, no matter how it was built
• Simulate multi-contract interactions more realistically
• Prepare for production-level usage with real code

We’ve also:

• Enabled gas usage tracking (experimental for now)
• Added support for Rust 1.87
• Rolled in Wasmer 6 for local devs, while keeping compatibility with Wasmer 2.2 on mainnet
• Improved the build system with auto-target install + opcode validation

Coming soon: v0.59 with Barnard support on devnet. Stay tuned.
