SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill allows users to query various blockchain networks for essential data, such as wallet balances, transaction history, gas prices, and smart contract details, without needing to directly interact with complex blockchain APIs.

Core Features & Use Cases

  • Multi-Chain Support: Query data from Ethereum, Polygon, Base, Arbitrum, and Optimism.
  • Data Retrieval: Fetch wallet balances, transaction history, gas oracle information, and smart contract ABIs.
  • Use Case: A developer needs to check the ETH balance of multiple addresses on the Ethereum mainnet and get current gas prices to estimate transaction costs.

Quick Start

Use the blockchain-scanner skill to get the ETH balance for the address 0x1234567890abcdef1234567890abcdef12345678.

FAQPage Schema
How do I query wallet balances and transaction history across multiple EVM blockchains?▼

To query EVM blockchain data, you can fetch wallet balances and paginated transaction history across networks like Ethereum, Polygon, Base, Arbitrum, and Optimism. This Skill retrieves up to 20 wallet balances and transaction records without requiring direct API interaction.

What is the best way to get current EIP-1559 gas prices for Ethereum transactions?▼

To get current EIP-1559 gas prices, you can query the gas oracle for real-time recommendations across supported networks like Ethereum mainnet. This helps estimate transaction costs accurately before broadcasting.

Can I retrieve verified smart contract ABIs on Polygon or Arbitrum?▼

Yes, you can retrieve verified smart contract ABIs on Polygon, Arbitrum, and other supported EVM networks. This allows you to interact with contract functions directly without manually sourcing the application binary interface.

How many wallet addresses can I check balances for at one time?▼

You can check wallet balances for up to 20 addresses simultaneously. This batch querying capability streamlines multi-wallet monitoring across Ethereum, Base, Optimism, and other supported chains.

Does this blockchain data tool work with Layer 2 networks like Base and Optimism?▼

Yes, the tool works with Layer 2 networks including Base, Optimism, and Arbitrum, alongside Ethereum and Polygon. It supports fetching transaction history, gas prices, and contract ABIs across these multi-chain environments.
