Trust, but Cap It: How We Gave Our Agents Wallet Allowances on Arc

Описание и применение

Агенты получили кошельки с ограничениями расходов, которые предотвращают транзакции сверх заданных лимитов, обеспечивая мгновенные отклонения, аудит и уведомления.

Задача

Agents need funded wallets that are safe to use at night, preventing overspending while maintaining auditability and alerts.

Результат

Agents can now operate with capped spending envelopes that deny transactions before they are constructed, eliminating gas costs and mempool delays, while providing instant alerts and audit logs.

Рабочий процесс

• Register wallet address with AgentBadge
• Attach envelope with perTxUsd, dailyUsd, etc.
• Reserve amount on transaction request
• If reserve succeeds, attempt to settle; on success record txHash
• If settle fails, release reserved amount
• Monitor alerts: cap_denied, failed, release_late, low_balance

Доказательства

agent wallets with spending envelopes — every payment an agent makes through AgentBadge runs under per-transaction, daily, weekly, and monthly caps, with a full audit trail and alerts.

Источник

The envelope denies before a transaction is constructed.

Источник

Reserve — the amount earmarks against the window on arrival; concurrent requests can't overspend the same budget.
