SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a comprehensive reference for interacting with and reading on-chain state within MultiversX smart contracts, simplifying access to crucial blockchain data.

Core Features & Use Cases

On-Chain Data Access: Retrieve caller information, account balances, block timestamps, ESDT token metadata, and more directly from self.blockchain().
Smart Contract Development: Essential for building smart contracts that need to query current blockchain conditions, user states, or token properties.
Use Case: A smart contract needs to verify the caller's EGLD balance before allowing a specific action. This Skill's methods enable that check.

Quick Start

Use the multiversx-blockchain-data skill to get the caller's address.

FAQPage Schema

How do I read caller and account balances in MultiversX smart contracts?▼

You can read caller and account balances in MultiversX smart contracts by using the `self.blockchain()` interface, which provides typed access to on-chain account state and EGLD balances directly within the contract logic.

What on-chain data is available through the MultiversX blockchain API?▼

The MultiversX blockchain API provides typed access to caller info, account balances, block and transaction details, ESDT token metadata, and contract code inspection through the `self.blockchain()` interface.

How do I check ESDT token metadata inside a MultiversX smart contract?▼

You check ESDT token metadata inside a MultiversX smart contract by calling the specific methods provided by the `self.blockchain()` interface to retrieve token properties directly from the on-chain state.

Can I retrieve block timestamps and transaction details using the MultiversX SDK?▼

Yes, you can retrieve block timestamps and transaction details using the MultiversX SDK by accessing the `self.blockchain()` interface, which exposes current block and transaction information for smart contract execution.

How do I verify a user's EGLD balance before allowing a smart contract action?▼

To verify a user's EGLD balance before allowing a smart contract action, use the `self.blockchain()` interface methods to query the caller's current account balance and enforce conditional logic based on the returned state.
