mvx_cache_patterns

What problem does it solve?

This Skill addresses the high gas costs associated with frequent storage operations on the MultiversX blockchain by implementing efficient caching strategies.

Core Features & Use Cases

• Gas Optimization: Significantly reduces transaction fees by minimizing expensive storage reads and writes.
• In-Memory Caching: Loads storage values into a struct on function entry and commits changes on exit, making intermediate reads free.
• Selective Write-Back: Only writes back modified fields, further saving gas.
• Use Case: For smart contract endpoints that read three or more storage values, using these cache patterns can lead to substantial gas savings.

Quick Start

Implement the write-back cache pattern with a Drop trait for your contract's storage fields.
