Spending limits an agent cannot raise.

The limit and the approval live in the vault contract, not where the agent can reach them. The agent pays within your rules. Going over a limit needs your signature over that exact payment.

01The rules

The agent can pay. It cannot change the rules.

Limits, recipients, approvers, pause and withdraw are all owner-only in the contract. The transcript below illustrates the rules; it is not a recording.

02How it works

Four steps, each one checkable on the chain.

Fund the vault
You put USDC in a vault you own, and set a per-payment limit, a daily limit and the vendors it may pay.
The agent pays
Routine payments within your limits go through on the agent's own request. The agent's key holds gas only.
You sign exceptions
Over a limit, the vault waits. You get an alert, review the recipient and amount here, and sign that exact payment.
A reviewer checks
One disclosed record, checked against the chain with the reviewer's own RPC. No other record is readable.

Who is this for?
