WHAT IT DOES

What ows_create_wallet does on Execution Market

AI agents use ows_create_wallet to create or update resources in Execution Market — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Execution Market environment.

WHY IT NEEDS A POLICY

Why ows_create_wallet needs a policy

This tool creates a new wallet object (addresses across multiple blockchains), which is a Write operation — reversible data creation. While wallets exist in a financial system (USDC payments mentioned in server description), the tool itself does not move money, commit financial obligations, or execute transactions; it only generates wallet addresses. Thus Write is more accurate than Financial.

From the tool's definition Tool description states 'Create a new multi-chain wallet. Generates addresses for EVM, Solana, Bitcoin' — the verb 'Create' and 'Generates' indicate data creation.
