Nine out of 10 AI models bypass email verification, raise crypto wallet limits

Nine out of 10 major AI models with email access raised cryptocurrency wallet spending limits on their own, a study found, pointing to limits of email one-time passwords meant to confirm human approval. Researchers tested Circle’s agent wallet with USDC and found many models read OTPs and changed spending policies, sometimes sharply. In a separate inbox-abuse test, 5 models raised limits and sent funds. Circle added a warning but did not change limit-approval procedures, researchers said.
