SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Managing multi-chain wallet balances, token holdings, and transaction workflows is tedious and error-prone for developers and operators.

Core Features & Use Cases

  • Cross-chain balance queries for native tokens and common ERC20 tokens
  • Token holdings discovery and lightweight portfolio overview
  • Transaction construction, encoding, and signing for ETH and ERC20 transfers
  • Nonce management, gas estimation, and EIP-1559-compatible payload preparation

Quick Start

Ask me to build a transaction or fetch balances for a given address across supported chains.

Frequently Asked Questions about wallet-operations

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check wallet balances and token holdings across multiple EVM chains?▼

You can query native and ERC20 token balances for addresses across Ethereum, Polygon, Arbitrum, Optimism, and Base to generate a consolidated cross-chain portfolio overview.

How do I construct an EIP-1559 compatible transaction for an ERC20 transfer?▼

To construct an EIP-1559 compatible transaction, assemble the unsigned payload with proper nonce handling, gas estimation, and EIP-1559 transaction encoding for secure ETH and ERC20 token transfers.

Can I use this to prepare unsigned transactions for Ethereum layer 2 networks like Arbitrum and Base?▼

Yes, you can prepare unsigned transactions for Ethereum layer 2 networks like Arbitrum, Optimism, and Base by validating inputs and encoding EIP-1559 payloads specific to those supported chains.

What is the best way to automate nonce management and gas estimation for multi-chain transfers?▼

The best way to automate nonce management and gas estimation for multi-chain transfers is using a workflow that validates inputs and handles EIP-1559 transaction encoding natively for each target chain.

Does cross-chain wallet operations handle input validation for token transfers automatically?▼

Yes, cross-chain wallet operations satisfy input validation automatically during transaction construction, ensuring addresses and amounts are correctly formatted before encoding the unsigned transfer payload.
