Ride your Perpl account
Use the account and the AUSD you already have on Perpl. No transfers, no gas.
Go to app.perpl.xyz/apikeys and connect the same wallet you already trade with on Perpl. That wallet owns your account and your AUSD.

It could, and that is the smoothest way: your wallet signs once, the key is made for you, nothing to copy. Perpl only accepts that one-signature request from websites it has approved, a safety check so a strange site can't make keys in your name. Until this app is on that list, the key is created on Perpl's own page and pasted here.
Signing every trade with your wallet instead would mean a pop-up on every lane change, which doesn't work in a game.
The other way in is the passkey wallet. Mera turns your Face ID or fingerprint into a Monad wallet that signs each order inside the app, with no key to paste and no pop-ups. It is a new wallet, so it starts empty: send it about 15 AUSD (Agora's dollar, the one Perpl uses for margin) and a little MON for gas, then deposit from Money.
Tip: orders from a key are sent onchain by Perpl for you (“one-click trading”), and Perpl pays the gas. If the cockpit says one-click trading is off, switch it on in your Perpl settings at perpl.xyz.
