Stemline carries your transaction along a private relay path before it ever touches the public mempool.

Send first.
Be seen later

You send an amount to an address and the first node to see it learns your city, your provider.

It walks first. Each relay passes it to exactly one other, so the first node to see it is never you.

Four to seven hops, and no relay can tell whether it is talking to the sender or to another relay.
