WHAT IT DOES

What ows_sign_erc8128_request does on Execution Market

AI agents invoke ows_sign_erc8128_request to trigger actions in Execution Market. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why ows_sign_erc8128_request is rated High

This tool signs HTTP requests using wallet-based authentication (ERC-8128), which is a cryptographic operation that authorizes actions on behalf of a wallet. In the context of a platform with USDC payments and escrow, signed requests can authorize financial or contractual operations. The description is truncated ('Returns ready-to-use' is incomplete), which lowers confidence slightly.
