May this agent submit this payment?

One governed payment, evaluated in your browser against a recipient's signed Proof Request, in two stages: permission before dispatch, evidence after. The recipient decides what counts as enough. Nothing is uploaded.

For: anyone who must approve what an agent does, or decide whether to rely on what it did.You get: why the action can proceed, or what stops it, one answer per question the recipient asked; then a decision you sign and the other side can check.

SandboxDemo keys sign every artifact. Signatures are real; identities are not.The bank ledger is simulated. No money moves.

Five guided scenes: the approved payment; the amount changes; submitted, not yet confirmed; the bank confirms; the same authorization, again; ten minutes pass. Then explore who must be satisfied and the ways it fails, or load your own Proof Request.
