Build your market-making prompt.

Say which stablecoins you're putting up and which currencies you want to make markets in, set your risk, then copy one prompt for the agent that will run rotor on your machine. Your setup lives in the address bar — bookmark or share it freely; it never contains secrets.

Currencies

Put up the stablecoins you're holding, then pick the currencies you want to make markets in. Each currency trades against every stablecoin you put up.

Stablecoins you're putting up

How much of each are you starting with? Leave one blank if you're not using it. You can add more.

Currencies to make markets in — quick-pick a region, then fine-tune below

Price reference — where each currency's rate comes from

“Auto” picks the best source per currency. Only Wise needs an API key (and it's optional); ECB, Fed, BNM, and MAS are keyless.

Risk level

Fixed bps Return bps

“Fixed” is how far quotes sit from the reference mid; “return” is the tighter spread used on the opposite side after a fill. Presets set both values — editing them switches risk to Custom.

Keys & APIs you'll need

Only your wallet key is always required — the rest are optional. You give them to the agent when it runs (save them in Manus's secrets store or your own shell, never on this page), and the generated prompt makes the agent test each value the moment you hand it over — a wrong key stops the setup before any order is placed.
