• SafeAdapter: Gnosis Safe multisig support — builds Safe transactions, EIP-712 signing, auto-executes when threshold == 1, proposes for co-signing when threshold > 1
• SmartWalletAdapter: Abstract base class extending WalletAdapter with get_owner_address(), is_deployed(), get_wallet_type_info() methods
• WalletFactory.from_erc4337(): Static factory for ERC-4337 wallets
