Open a vault
Give your agent an allowance — never your wallet. Set the rules once; Nanny enforces them on-chain, even when your agent is fooled.
Activity and Agent unlock once your vault exists — they both act on a specific vault.
Trickles in second by second — not all at once.
Unspent allowance stops growing here.
A ceiling on any single payment.
Your agent can pay only these. Anywhere else is blocked on-chain.
Stays in the vault. Your agent never holds it.
