Signed is developing trust infrastructure for AI agent payments. Its technology allows AI agents to prepare and execute payments within user-approved mandates while requiring human approval for transactions outside those mandates. Signed verifies agent keys, user signatures, mandates, payees, accounts, and amounts, and preserves proof of payment decisions. It integrates with apps, accounting systems, banks, and card platforms, but does not hold, move, or insure money; the user’s bank executes the payment.
