Evm Wallet
Manage EVM wallets and interact with smart contracts using the Foundry `cast` CLI — covering wallet creation, vanity addresses, keystore management, message signing, ETH transfers, contract calls, gas estimation, and on-chain queries. Use this skill whenever someone mentions wallets, private keys, signing, ERC-20 operations, sending transactions, checking balances, Foundry, or cast. Also use it when calling or deploying any EVM contract from the command line, or managing token approvals.
