STEP 1
Owner sets the policy
The vault owner fixes the rules on-chain: a per-transaction cap, a daily cap, and the list of recipients the agent is allowed to pay.
STEP 2
Agent spends inside the caps
The AI agent holds its own key and pays for services from the vault. Any payment outside the policy reverts on-chain, no exceptions.
STEP 3
Every move is auditable
Deposits, spends and policy changes are recorded as events on Arbitrum Sepolia, so the owner always sees the same truth as the chain.

Over the cap, the chain says no: a 0.5 ETH payment from the agent reverted on this vault because it exceeded the 0.01 ETH per-transaction limit.

A payment that fails any check reverts on-chain. In the live demo, a 0.5 ETH payment was rejected for exceeding the per-transaction cap.
