System Documentation

What problem does it solve?

This Skill enables reading data directly from another smart contract's storage without incurring the gas costs and complexities associated with traditional proxy calls, specifically for same-shard contracts.

Core Features & Use Cases

  • Direct Storage Access: Utilizes storage_mapper_from_address to read storage variables.
  • Zero Gas Overhead: Avoids proxy call gas fees, only incurring the cost of a storage read.
  • Use Case: Efficiently retrieve the total_supply of a token or a user's balance from another contract on the same shard without making an external call.

Quick Start

Use the mvx_cross_contract_storage skill to read the external_total_supply from the contract at address erd1... for the token identifier 'MYTOKEN'.
