Monad agent payment control

Automated execution, human takeover available

Agent-native payment system on Monad Testnet

SmartBudget

Smart Budget gives AI agents controlled payment capability. Funds remain in the user's vault, agents pay through scoped session keys, and every execution stays bounded by policy rules and human pause controls.

Control model

Human takeover ready

Payment path

Vault -> session key -> x402 request

Operator brief

System status

Automation always runs inside explicit boundaries

This section answers three questions clearly: who keeps final control, what agents are allowed to do, and how operators can take over immediately when needed.

Operator brief

Control

Even during agent execution, the owner can pause the vault and stop subsequent payments at any time.

Operator brief

Scope

Session keys define expiry, per-tx caps, daily budgets, and access boundaries together.

Operator brief

Settlement

x402 requests settle through a clear and traceable machine-payment path.

System status

Vault state

Funds stay centralized while execution rights are granted as needed.

System status

Policy rules

Limits, categories, and recipient constraints stay active inside the system.

Recovery

Pause, revoke, and rotate paths remain clear and always available.

Capabilities

A controlled, auditable execution environment for agent payments

Smart Budget is an agent-native payment system built for Monad. Users retain control of the vault, agents execute payments through scoped session keys, and every action stays inside limits, timing rules, and policy boundaries.

Control overview

Control rights, authorization scope, and takeover paths stay visible

Asset control

Funds remain inside the user's deployed vault contract, and agents never receive unrestricted primary control.

Session keys

Each agent permission includes expiry, per-tx caps, daily budgets, and whitelist constraints.

Audit and recovery

Payment history, policy hits, and manual intervention paths remain traceable, with pause, revoke, and rotate always available.

Product structure

The page is organized around four core objects: the vault, session keys, policy validation, and human takeover, helping users understand how agent payments are safely authorized and executed.

Scoped authority

Session keys define payment duration, spending ceilings, and accessible scope.

Machine payment rail

Supports x402 and agent-to-service automated settlement flows.

Continuous visibility

Vault state, authorization state, and payment results stay readable in one place.

Execution path

Funds, policy, and settlement states move together in real time

Guardrails enabled

The lower section connects funding, policy checks, session authorization, and payment execution into one readable flow so operators can quickly judge whether the system is safe, executable, and recoverable.

Vault funds
Funds stay concentrated in the user's controlled vault address
Policy checks
Limits, categories, and recipient rules are validated before execution
Session authority
Expiry and spend boundaries remain active for every agent permission
Machine settlement
x402 payment requests can be executed directly by scoped agents

Per-tx limit

Limit active

Daily budget

Budget active

Emergency pause

Manual control available

Runtime overview

Key events and execution state stay up to date

The page uses event feeds and state modules to show vault funding, session key issuance, x402 settlement, and human takeover status so operators can quickly confirm the current runtime condition.

Product entry

The home page explains the system. `/vault` runs the operations.

The home page focuses on product capabilities, control model, and payment flow, while the console handles deposits, session key management, policy configuration, and payment review.

Route split

The system stays clearer and more credible when each page has one job.

Home page

Route `/` explains system capabilities, control boundaries, and machine-payment scenarios.

Console operations

`/vault` handles deposits, session key management, policy review, and payment approval flows.

Human override

Pause and recovery paths stay explicit instead of requiring extra navigation to find.

Product entry page

Page /vault

Operator console

Concentrates deposits, session keys, pause controls, and payment review into one surface built for execution.

Human takeover active

Human takeover paths remain explicit

The system consistently reinforces that automation is delegated and bounded, never unchecked, and that pause and recovery remain visible throughout.
