Smart Contract Skill

Provides read-only smart contract interaction capabilities:

• Read ERC20 token info (name, symbol, decimals, total supply)
• Check ERC20 token balance for an address
• Check ERC20 allowance for spender
• Read contract storage slots
• Decode contract events/logs
• Get contract code

Use builtin_smart_contract tool with fields:

• operation: one of "erc20_info", "erc20_balance", "erc20_allowance", "erc721_owner", "erc721_metadata", "code", "storage"
• contract_address: Ethereum contract address
• address: (optional) wallet address for balance/allowance queries
• spender: (optional) spender address for allowance query
• token_id: (optional) NFT token ID for ERC721 queries
• network: (optional) Ethereum network: "mainnet", "sepolia", "holesky" (default: "mainnet")

Note: Only read-only (view/pure) contract calls are supported. No state-changing transactions.
