Issue a City Permit

The Mayor grants Agent City a capped operating budget from your wallet. No keys are shared — overspend reverts by construction. Revoke anytime from /app.

Connect your wallet
Click Connect MetaMask and approve the account request in the MetaMask Flask popup. Verify the active network shows Base Sepolia — the permit targets chain 84532.
Issue the permit
Click Issue Permit and approve the erc20-token-periodic permission in the MetaMask popup. The City Treasury receives a scoped delegation: ≤ 5 USDC per day, expiring in 7 days. Your private key never leaves your device.
Server validates the permit
The City Treasury decodes the granted context on-chain and confirms the delegation chain is intact. A valid permit shows the APPROVED stamp below. Then open /app and dispatch the city — every payment chains under your authorization.
