Calls to execute_agent_payment on Nov 5, 2026 (UTC). The payment is a 0.01 NEAR transfer from the vault; the two rejections are panics raised by the vault contract itself. This demo screen does not broadcast.

REALThe vault and agent accounts, the limited agent key, and the three transactions above run on NEAR testnet (test tokens, no monetary value).
SIMULATEDThe attack scenarios, risk scores, and local revoke on this screen are for demonstration. They send no transactions.

Agent key

VERIFIED NOV 9, 2026
