What it can do without asking

DocumentedConditional

Stage 5 within policy; stage 4 when approval is required.

  • Read balance

    • Stage 1, reads wallet or data.

      Reads wallet or data

      When Authenticated wallet.

  • Execute transaction

    • Stage 5, executes without per-action human approval.

      Executes without per-action human approval

      When Within Guard policy and no approval-triggering risk.

      Limits Documented enforcement: Rolling USD outflow threshold; excess or increase requires 2FA. Excluded paths: Signatures such as Permit2 excluded; Outside-backend or unsimulatable outflows may not be measured reliably. Stage 5 does not mean limited or safe.

    • Stage 4, executes after per-action human approval.

      Executes after per-action human approval

      When Policy violation or flagged transaction requires 2FA.
