MultiversX Sharp Edges

A catalog of non-obvious behaviors, "gotchas," and platform-specific quirks that frequently lead to bugs in MultiversX smart contracts and dApps. Understanding these sharp edges is essential for writing correct code.

When to Use

• Debugging unexpected contract behavior
• Reviewing code for subtle platform-specific issues
• Onboarding to MultiversX development
• Checking if a bug might be caused by a known quirk
• Preparing for security audits

1. Async Callbacks & Reverts

The Sharp Edge

When an async call fails, the #[callback] is still executed, but state changes from the original transaction are NOT automatically reverted.
