SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the friction of working with Wrapped Ether on Base Sepolia by giving you a reliable way to inspect balances, wrap and unwrap ETH, and manage token approvals without manually assembling contract calls.

Core Features & Use Cases

  • Balance and allowance checks: Read WETH name, symbol, decimals, supply, balances, and spender allowances before sending a transaction.
  • Wrap and unwrap ETH: Deposit native ETH into WETH or withdraw WETH back to ETH with the correct contract interaction.
  • Approve and transfer flows: Set ERC-20 allowances, transfer WETH directly, or move tokens with transferFrom when approval already exists.
  • Wallet-executed transactions: Use keypo-wallet for sending single calls or batched calls on Base Sepolia when you need secure onchain execution.

Quick Start

Ask the skill to help you check a Base Sepolia address's WETH balance, then wrap the ETH amount you choose or prepare the exact calldata needed for an approval or transfer through keypo-wallet.
