What if you could give an AI agent spending power without handing over your entire wallet?

One dev is testing exactly that on $CKB with QuotaCell.

How it works:

You set a spending cap from a shared wallet. Teammates or AI agents can transact within those limits. The $CKB network itself enforces the rules, not just the app layer. Even if a payment is built outside the app, the chain validates it.

You can revoke access anytime. In testing, the owner killed a helper's spending rights mid-flight. Next payment? Rejected. Owner then closed the shared wallet and recovered test funds. No helper signature needed.

The reality check:

This is one dev on a private local testnet with play money. Not public testnet. Not audited. Closing the wallet still locks ~600 $CKB for now.

So no, don't trust this with real funds yet.

But here's why it matters: As AI agents start handling on-chain payments, enforceable spending limits become critical infrastructure. An agent gets a budget, not root access.

That's the kind of unsexy, high-impact building that actually moves crypto forward. Watching $CKB closely on this one.
